Proper fueling
prevents fatigue during long workouts
By Nancy Clark, MS, RD
Active.com 1/7/2003
I'm at the gym from 5:30 to 7:00 pm
and feel exhausted by the end of my workout. What can I do to prevent
fatigue?"
"I'm training for a marathon ... I
dread the long runs. I'm dragging after 12 miles. Any suggestions for
how to boost my energy?"
"I'm whipped by the end of my
after-school soccer practices ..."
Sound familiar? Preventing fatigue is the
No. 1 concern of active people who exercise for more than an hour.
This article can help you enjoy high
energy and enhanced stamina during long, hard exercise sessions. (For
shorter exercise sessions, a pre-exercise snack and some water should
fuel you well.)
To prevent fatigue during extensive
exercise that lasts for more than 60 to 90 minutes, you have two
nutrition goals:
1. To prevent dehydration
2. To prevent your blood sugar from
dropping
The following tips can help you reach those goals.
Sweat and dehydration
When you exercise hard, you sweat.
Sweating is the body's way of dissipating heat and maintaining a
constant internal temperature (98.6°F).During hard exercise, your
muscles can generate 20 times more heat than when you are at rest.
You dissipate this heat by sweating. As
the sweat evaporates, it cools the skin. This in turn cools the blood,
which cools the inner body. If you did not sweat, you could cook
yourself to death.
A body temperature higher than 106°F
damages the cells. At 107.6°F, cell protein coagulates (like egg
whites do when they cook), and the cell dies. This is one serious
reason why you shouldn't push yourself beyond your limits in very hot
weather.
When you sweat for more than an hour, you
lose significant amounts of water from your blood. The remaining blood
becomes more concentrated and has, for example, an abnormally high
sodium level. This triggers the thirst mechanism and increases your
desire to drink.
To quench your thirst, you have to replace
the water losses and bring the blood back to its normal concentration.
Unfortunately for athletes, this thirst
mechanism can be an unreliable signal to drink. Hence, you should plan
to drink before you are thirsty. By the time your brain signals thirst,
you may have lost 1 percent of your body weight, the equivalent of 1.5
pounds (24 ounces) of sweat for a 150-pound person.
This 1 percent loss corresponds with the
need for your heart to beat an additional three to five times per
minute. This contributes to early fatigue.
Thirst sensations change with age and
older people, even athletes, become less sensitive to thirst. For
example, 56-year-old hikers became progressively dehydrated during 10
days of strenuous hill walking. The younger, 24-year-old hikers
remained adequately hydrated. This means older people, in particular,
should carefully monitor their fluid intake.
Light-colored urine, in significant
volume, is a sign of adequate hydration.
Most athletes voluntarily replace less
than half of sweat losses; thirst can be blunted by exercise or
overridden by the mind. To be safe, always drink enough to quench your
thirst, plus a little more.
If you know how much you sweat, you can
then replace those losses according to a plan. To learn your sweat rate
(and fluid targets), weigh yourself naked before and after a workout.
For every pound (16 ounces) you lose, you should strive to replace 13
to 16 ounces (80 to 100 percent of that loss) while exercising.
This requires training your gut to handle
this volume. Do not drink more water if your stomach is already
sloshing; enough is enough!
You might find it helpful to figure out
how many gulps of water equate to 16 ounces, and even set an alarm
wristwatch to remind you to drink on schedule. You'll also need to plan
on having the right quantity of enjoyable fluids readily available. Do
not be in such a rush to start your workout that you fail to bring with
you the sports drinks and fluids that will enhance your efforts.
Carbohydrates and blood sugar
As I?ve mentioned above, you can
significantly increase your stamina by consuming a pre-exercise snack
that provides fuel for the first hour of the workout and by drinking
adequate fluids during exercise.
The third trick to enhancing endurance is
to consume carbs after an hour of exercise. Depending on your body size
and ability to tolerate fuel while you work out, you'll want to target
100 to 250 calories of carbohydrates per hour of endurance exercise.
The larger you are, the more calories you
need. For example, if you weigh 180 pounds, you should target about 250
calories per hour, such as 8 ounces of a sports drink every 15 minutes,
or a 250-calorie energy bar plus water.
During a moderate to hard endurance
workout, carbohydrates supply about 50 percent of the energy. As you
deplete carbohydrates from muscle glycogen stores, you increasingly
rely on the carbs (sugar) in your blood for energy. By consuming
carbohydrates such as sports drinks, bananas, or energy bars during
exercise, you can both fuel your muscles as well as maintain a normal
blood sugar level.
Because your brain relies on the sugar in
your blood for energy, keeping your brain fed helps you think clearly,
concentrate well, and remain focused. So much of performance depends on
mental stamina; maintaining a normal blood sugar level is essential to
optimize your workouts and boost your stamina.
Your body doesn't care if you ingest solid
or liquid carbohydrates, both are equally effective forms of fuel. You
just have to learn which sports snacks settle best for your body: gels,
gummy bears, dried figs, animal crackers, defizzed cola, whatever.
Despite popular belief, sugar can be a
positive snack during exercise and is unlikely to cause you to "crash"
(experience hypoglycemia). That's because sugar feedings during
exercise result in only small increases in both insulin and blood
glucose. Yet, too much sugar or food taken at once can slow the rate at
which fluids leave the stomach. Hence, "more" is not always better.
Because consuming 100 to 250 calories per
hour of exercise (after the first hour) may be far more than you are
used to taking in during exercise, you need to practice fueling while
exercising to figure out what foods and fluids settle best.
You'll learn through trial and error which
snacks help prevent fatigue, boost performance and contribute to
enjoyment of your long, hard workouts
Athletes and protein:
The truth about supplements
By
Nancy Clark, MS, RD
Active.com 1/22/2003
When you look at the ads in almost any sports publication, you cannot
help but notice the supplement industry is hard at work promoting
protein powders, bars and shakes.
Their goal: to convince athletes they need extra protein to
build muscles and recover from exercise. Never before have I talked to
so many frenzied athletes, bodybuilders and marathoners alike, who are
worried their standard diets are protein-deficient and inadequate to
support their sports program. They commonly ask: What's the best
protein supplement?
My response: Why do you think you even need a protein
supplement in the first place? You can easily get the protein you need
through standard foods. Believe it or not, very few athletes need any
type of protein supplement.
Yes, protein supplements can be helpful in certain medical
situations. For example, an athlete with anorexia may be more willing
to consume a protein shake than eat tuna, cottage cheese or chicken.
Patients with cancer or AIDS often benefit from protein supplements if
they are unable to eat well.
But I have yet to meet a healthy athlete who is unable to
consume adequate protein through his or her sports diet. Hence, the
purpose of this article is to look at the myths and facts surrounding
protein supplements, so you can make informed decisions regarding your
sports diet.
How much is enough?
Only 10% to 15% of total calories need to come from protein.
Although athletes require slightly more protein than does a sedentary
person, a hungry athlete tends to eat hefty meals with large portions
of protein-rich foods.
That extra peanut butter sandwich, second chicken breast at
dinner and taller glass of milk satisfies any and all protein needs
without any supplements.
Following are recommendations for a safe, adequate protein
intake:
(numbers are given for grams per pound of body weight, with an example
for a 150-pound person):
Sedentary person: 0.4 gms/lb; 60 gms/150 lb person
Recreational exerciser, adult: 0.5 - 0.75, 75 -112
Competitive athlete, adult: 0.6 - 0.9, 90 - 135
Growing teenage athlete: 0.8 - 0.9, 120 - 135
Dieting athlete, reduced calories: 0.8 - 0.9, 120 - 135
Maximum for all healthy athletes: 0.9 gram/lb (2 gm/kg)
Note: Protein needs change depending upon calorie
intake. That is, if you are dieting to lose weight and are in calorie
deficit, you will need more protein than if you are eating adequate
calories. Your muscles burn protein for energy when fuel is scarce.
Example: If you weigh 160 pounds and want the maximum
acceptable protein intake (0.9 gms pro/lb), you'd need 144 grams of
protein ? an amount you could easily consume from a day's diet that
includes 1 quart skim milk (30 gms protein), 1 can tuna (30 gms pro),
and 8 ounces chicken breast (70 gms pro).
The small amounts of protein you get from the foods that
fill out the rest of your diet (cereal, bread, broccoli, frozen yogurt,
etc.) will bring you to more than 144 grams of protein. More protein
will not be "better."
And no scientific evidence supports the idea the protein or
amino acids in supplements are in any way superior to the protein from
eggs, milk, lean meats, fish, soy or other ordinary foods.
Is more better?
Eating more than the recommended protein intake offers no
benefits. Apart from being costly, a protein-based diet commonly
displaces important carbs from the diet. That is, if you have an omelet
and a protein shake for breakfast instead of cereal with banana, you'll
consume fewer carbs to fuel your muscles properly.
Carbs are the primary fuel for athletes who do
muscle-building resistance exercise. Once your muscles become
carb-depleted, fatigue sets in and your workout is over. Your diet
should provide extra carbs, not extra protein.
If you consume too much protein from supplements, you may
also fail to invest in optimal health. For example, I had one client
who daily ate five protein shakes and four protein bars ? to the
exclusion of standard food. Displacing natural foods with engineered
foods (such as protein supplements) limits your intake of the
vegetables, fruits, grains, fiber, phytochemicals, natural vitamins and
other health-protective nutrients that Nature puts in whole foods.
Pre- and post-exercise protein
Q. I've heard I should eat a protein bar for a
pre-exercise snack?
A. Protein has typically been consumed at meals, away
from the time of exercise. New research suggests eating protein before
you work out can optimize muscle development. Pre-exercise protein
digests into amino acids that are then ready and waiting to be taken up
by the muscles after a strength workout.
This does not mean you'll evolve into Charles Atlas; you'll
simply optimize your body's ability to build and repair muscle at that
moment.
The amount of protein needed for this benefit is tiny ?
about 6 grams (less than 1 ounce of meat). You certainly do not need a
hefty pre-exercise protein bar nor a thick steak. A yogurt, cereal with
milk, or a slice of peanut butter toast will do the job just fine! A
pre-exercise protein supplement is a needless expensive.
Protein source (with cost/grams of protein/cost per gram)
MetRx Big 100 Bar: $2.50, 26 grams, 9.5 cents
PowerBar ProteinPlus: $1.95, 24, 8 cents
Tuna, 6 oz can: $0.99, 30, 3.5 cents
Skim milk, 1 quart: $0.75, 32, 2.5 cents
Peanut butter, 2 tbsp: $0.15, 7, 2 cents
Q. I?ve heard I should I eat protein right after I
exercise to enhance the speed of glycogen recovery?
A. Supposedly, eating some protein along with
carbohydrates after exercise stimulates insulin, and that stimulates
greater glycogen uptake. At least five carefully controlled studies
have shown the addition of post-exercise protein does not offer any
advantages when the athlete eats adequate calories from carbs.
My advice: If you refuel with wholesome, refreshing meals
that appeal to you, you'll inevitably get the nutrients you need. Fruit
and yogurt, nuts and raisins, bagel sandwich, and pasta with meat sauce
are just a few popular recovery foods that offer an enjoyable
combination of both protein and carbs to refuel, rebuild and repair
muscles.

Breakfast: the
most important meal of an athlete's day
By Nancy Clark, MS, RD
Active.com 2/12/2003
Without question, breakfast is the meal
that makes champions. Unfortunately, many active people follow a
lifestyle that eliminates breakfast or includes foods that are far from
champion-builders.
I commonly counsel athletes who skip
breakfast, grab only a light lunch, train on fumes, gorge at dinner and
snack on "junk" until bedtime. They not only rob their bodies of the
nutrients needed for health, but also lack energy for high-quality
workouts.
A satisfying breakfast tends to invest in
better health than does a grab-anything-in-sight dinner. Sarah, a
collegiate athlete, learned that fueling her body's engine at the start
of her day helps her feel more energetic and also able to choose better
quality lunch and dinner foods.
That is, when she has granola, banana and
juice in the morning, as well as a sandwich and yogurt for lunch, she
stops devouring brownies after dinner.
Excuses to skip breakfast are abundant:
"No time," "I'm not hungry in the morning" and "I don't like breakfast
foods." Weight-conscious athletes pipe up, "My diet starts at
breakfast."
These excuses are just that, excuses; they
sabotage your sports performance.
Here's a look at the benefits of eating
breakfast. I hope to convince you that breakfast is the most important
meal of your sports diet.
Breakfast for dieters
If you want to lose weight, you should
start your diet at dinner, not at breakfast! For example, do not eat a
meager bowl of Special K for your "diet breakfast." You'll get too
hungry later in the day and crave sweets.
A bigger breakfast (cereal + toast +
peanut butter) can prevent afternoon or evening cookie-binges. An
adequate (500 - 700 calorie) breakfast provides enough energy for you
to enjoy your exercise, as opposed to dragging yourself through an
afternoon workout that feels like punishment.
If you are trying to lose weight, you
should target at least 500 to 700 calories for breakfast; this should
leave you feeling adequately fed.
To prove the benefits of eating such a big
breakfast, try this experiment:
1. Using food labels to calculate
calories, boost your standard breakfast to at least 500 calories. For
example, add to your english muffin (150 calories): 1 tablespoon peanut
butter (100 cal.), 8 oz. orange juice (100 cal.) and a yogurt (150
cal). Total: 500 calories.
2. Observe what happens to your
day's food intake when you eat a full breakfast vs. a skimpy "diet
breakfast." The 500+ calorie breakfast allows you to successfully eat
less at night and create the calorie deficit needed to lose weight.
Remember: Your job as a dieter is to fuel
by day and lose weight by night. Successful dieters lose weight while
they are sleeping; they wake up ready for another nice breakfast that
fuels them for another high-energy day.
Breakfast for the morning exerciser
If you exercise first thing in the
morning, you may not want a big pre-exercise breakfast; too much food
can feel heavy and uncomfortable. However, you can likely tolerate half
a breakfast, such as half a bagel, a slice of toast, or a banana before
your workout.
Just 100 to 300 calories can put a little
carbohydrate into your system, boost your blood sugar so that you are
running on fuel, not fumes, and enhance your performance.
You'll likely discover this small
pre-exercise meal adds endurance and enthusiasm to your workout. In a
research study, athletes who ate breakfast were able to exercise for
137 minutes as compared to only 109 minutes when they skipped this
pre-exercise fuel.
After his morning workout, Jim, a banker,
felt rushed and was more concerned about getting to work on time than
eating breakfast. Using the excuse "No time," he overlooked the
importance of refueling his muscles.
I reminded him: Muscles are most receptive
to replacing depleted glycogen stores within the first two hours after
the workout, regardless of whether or not the athlete feels hungry. I
encouraged Jim to be responsible! Just as he chose to make time for
exercise, he could also choose to make time for breakfast.
One simple post-exercise breakfast is
fluids. Liquid breakfasts take minimal time to prepare and very little
time to drink, yet they can supply the calories, water, carbohydrates,
protein, vitamins and minerals you need ? all in a travel mug. (You can
always get coffee at the office.)
Because Jim felt thirsty after his morning
workout, he found he could easily drink 16 ounces of juice or lowfat
milk. Sometimes, he'd make a refreshing fruit smoothie with milk,
banana and berries.
Later on mid-morning, when his appetite
returned, Jim enjoyed the rest of his breakfast: (instant) oatmeal,
multi-grain bagel with peanut butter, yogurt with granola, a banana ?
or any other carbohydrate-rich foods that conveniently fit into his
schedule.
This nutritious "second breakfast"
refueled his muscles, abated hunger and curbed his lunchtime cookie
cravings.
Breakfast for the noon-time, afternoon and evening exerciser
A hearty breakfast is important for people
who exercise later in the day. It not only tames hunger but also
provides the fuel needed for hard workouts.
Research has shown that athletes who ate
breakfast, then four hours later enjoyed an energy bar five minutes
before a noontime workout were able to exercise 20% harder at the end
of the hourlong exercise test compared to when they ate no breakfast
and no pre-exercise snack. (They worked 10% harder with only the snack.)
Breakfast works! Breakfast + a
pre-exercise snack works even better!
What's for breakfast?
From my perspective as a sports
nutritionist, one of the simplest breakfasts of champions is a
wholesome cereal with lowfat milk, banana and orange juice. This
provides not only carbohydrates to fuel the muscles, but also protein
(from the milk) to build strong muscles, and numerous other vitamins
and minerals such as calcium, potassium, vitamin C, iron (if you choose
enriched breakfast cereals) and fiber (if you choose bran cereals).
Equally important is the fact that cereal
is quick and easy, requires no cooking, no preparation, no
refrigeration. You can keep cereal at the office, bring milk to work
and eat breakfast at the office. Breakfast is a good investment in a
productive morning.
The bottom line
Breakfast works wonders for improving the
quality of your diet. That is, eating breakfast results in less "junk
food" later in the day. Breakfast also enhances weight control, sports
performance, daily energy levels and future health.
Breakfast is indeed the meal of champions.
Make it a habit ? no excuses!
Sample grab-and-go sports breakfasts
Bran muffin plus a vanilla
yogurt
Two slices of last night's left-over thick-crust pizza
Peanut butter-banana-honey sandwich
Pita with 1 to 2 slices of lowfat cheese plus a large apple
Baggie of lowfat granola with a handful of raisins (preceded
by 8 oz. lowfat milk before you dash out the door)
Cinnamon raisin bagel (one large or two small) plus a can of
vegetable juice

Recovery eating:
Don't let your energy reserves run low
5/13/2003
You can speed your
recovery considerably and maximize your training gains after a long
race or a hard training session if you eat (and drink) for recovery.
Your muscles are most receptive to reloading glycogen in a 15- to
30-minute window immediately following exercise. Blood flow to muscles
is enhanced immediately following exercise.
Muscle cells can pick up more glucose and are more sensitive to the
effects of insulin, a hormone that promotes the synthesis of glycogen
by moving glucose out of the bloodstream and into cells.
It takes at least 20 to 24 hours of refueling with carbohydrate-rich
foods to replenish your muscle stores fully, so daily workouts can
leave you running on low fuel stores. Since the effects of dehydration
and muscle glycogen depletion can be cumulative, inadequate refueling
can contribute to overtraining syndrome.
Here are strategies you can use to improve your recovery eating
habits and make sure that you are always running on a full tank.
Don't forget fluids. Your body cannot perform any of its
metabolic jobs well if you are dehydrated. Weigh yourself periodically
before and after a hard workout to estimate how much fluid you need to
replace. Remember, "a pint's a pound" ? every one pound lost during a
workout reflects two cups of water loss. Sports drinks are an efficient
fluid replacement since they also provide carbohydrates and sodium.
Fruit juices, low-fat milkshakes, and smoothies are also good
choices since you get both liquid and carbs. Avoid drinking copious
amounts of plain water if your workout has been over an hour. You'll
need to consume some electrolytes and sodium as well.
After exercise, you can eat or drink your carbs, but do
it quickly. Aim for about half a gram of carbohydrate per pound of
body weight (about 50 to 100 grams) within the first 15 to 30 minutes
after a long race or workout. Most sports drinks contain only 14 to 20
grams per cup, while fruit juices contain about 25 to 40 grams per cup.
The best recovery plan also includes eating carb-rich foods as
soon as you can tolerate them. Try yogurt, fresh fruit, an energy
bar, or a bagel. You may be able to boost the rate at which your
muscles store glycogen, as well as speed up the recovery and repair of
muscle tissue, by ingesting protein in combination with carbohydrate at
this time. The results of one study suggest using one gram of protein
per three grams of carbohydrate.
Try to eat (or drink) an additional 50 to 100 grams of
carbohydrates every two hours until your next full meal. Think of
whole grains, fresh fruits, dried fruits, pretzels, whole-grain cereal
and non-fat or low-fat dairy.
Don't wait for your appetite to return after a long race. The
longer you wait to eat, the less glycogen you store and the longer it
takes to recover. Intense or exhaustive exercise may depress your
appetite. Anticipate that, and have palatable food ready to eat.
Make notes about your food choices in your running log to help
you keep track of what worked well and what didn't.
Maximize your
potential through mental training and focus
By Adam Zucco
UltraFit.com 7/2/2003
Focusing on immediate goals is a key
part of mental training.
In his book In Pursuit of Excellence: How to Win in Sport and Life
Through Mental Training, internationally acclaimed author and sport
psychologist Terry Orlick outlines his techniques that have helped
Olympic athletes and ordinary people maximize their potential and
achieve their goals.
I have been working with some of my athletes in regards to mental
training, specifically focus, using the principles that Orlick explores
in his book.
Principles of Focusing
1. Try to remain oblivious to the
outside world. Orlick provides great examples of how well we are able
to push ourselves when we are not aware that we are being "scored." Ask
yourself how things change for you when you realize people expect
things out of you.
2. Focus is something that requires practice. The author describes a
technique using an index card with a dime-sized black dot on it. He
tries to study the dot until there is really nothing else in his world
other than the dot. It becomes almost like a controlled daydream.
Practice imagery along with this for the most effectiveness.
3. Learn to put less thought into all of your reactions. This will take
some practice, but try letting your body go a few times and see what
happens. Do not overthink all the things that you do.
4. Learn to use reminders to help you refocus.
If you experience problems focusing, then you have to learn to just let
it happen. Focus is not something that can be forced.
The difference between your best and worst performances usually comes
down to focus. In our worst performances, we most likely let negative,
anxiety-producing or distracting thoughts, like worrying about other
competitors, rule our emotions.
Focusing Strategies
1. Return to the
basics and follow a pre-practiced plan.
2. Focus only on your immediate goal.
3. Reassure yourself that you are trained, and that you are ready.
4. Remind yourself of past performances.
5. Remember that your goals are realistic; all you want to do is what
you know you can.
6. Focus on doing what is right for you rather than worrying about what
is wrong.
7. Imagine perfect execution of your skill.
8. Stay in the moment.
9. Intensify your focus on form.
10. Remind yourself that it is just another performance.
11. If you hate it, leave it.
Breathing 101:
Increase your efficiency for better oxygen uptake
By Thomas Chapple
UltraFit.com
9/3/2003
For some reason we're taught to expand
our chest when we breathe. This is not the most effective way to
completely fill the lungs, and is not how our bodies are designed to
inhale.
The diaphragm is the muscle located under
the lungs that is designated to expand the lungs and bring air into
them.
To breathe efficiently by using the
diaphragm effectively, think about drawing air into the bottom third of
your lungs as you expand your belly like a balloon.
Try doing this while inhaling through your
nose and you'll notice a relaxing sensation throughout your body.
Take a few moments before each workout to
sit quietly and practice breathing through your nose and with the
diaphragm. This will start your workout in the right frame of mind and
with correct breathing.
Keep reminding yourself how to breathe
with the diaphragm throughout your workout, and return to it if you
fall back on incorrect breathing.
Another breathing aid is to focus on
exhaling forcefully during climbing and hard efforts. Once you've
developed the habit of filling your lungs completely by breathing with
the diaphragm, your body will take care of the inhaling portion on its
own.
By forcing the air out of your lungs
you'll develop a more complete, efficient breathing cycle. Short,
shallow breaths don't completely fill or empty the lungs and will
dilute incoming oxygen with carbon dioxide.
I've also found that airflow improves if I
drop my jaw and open my mouth in an oval shape (vertically) during hard
efforts
Feeding our muscles: A
key to smart training
By June M.
Lay
HealthNewsDigest.com 9/29/2003
Today we discuss "feeding our muscles" since the fuel we give
our muscles plays an important part in being able to "smart
weight train" and it's also an important factor in avoiding an
injury.
So, whether our goal is to tone, get strong, gain muscle, heal
from an injury, or participate in a sport activity, we need to feed our
muscles!
Many of us think that if we eat lots of protein, we'll get
lean, strong and we'll build muscle. Let me say now that it is the
carbohydrates that we eat that gives us the energy to push the weights,
to use the protein we do eat to build muscle.
Those of us who participate in endurance sports such as
running, cycling etc. know the importance of eating a diet high in
carbohydrates with some extra protein. But did we know, for instance,
that carbs are the foundation to our performance, whether to power our
tennis game, aerobic workout, or bodybuilding routine?
So, here are a few sport nutrition rules to "Feed our
muscles":
Eat enough and often enough
When we eat enough calories and we eat often, we fuel our
muscles, not just for getting around, but for all the additional
activities, especially if we are active in sports.
When we restrict our calories too much (this goes for us
dieters) over a period of time, we send a signal to our body that a
famine is coming. The body may then adjust our metabolic rate to slow
down to conserve calories. Result? Most likely less strength, less
energy, and even higher body fat!
Eat carbohydrates
Yes, let's eat the dreaded starches! When we eat enough
carbohydrates, we give our muscles the fuel to work out hard. This in
turn will give our body the need to utilize all that protein we're
taking in to make more muscle (when we tone we add muscle fibers too,
so this is not just for bodybuilders).
Carbohydrates also feed our brain, so when our blood sugar
levels are low from not eating enough carbs, we will impair our energy,
focus, and performance.
When we are in short supply of carbs, the process of turning
protein into fuel for our muscles and brain is costly to our body. We
impair our performance, our ability to build and repair muscle, our
health and even our ability to lose weight (ever get constant sugar
cravings after eating mostly protein?).
Lastly, high-protein diets can cause dehydration. This is
deadly to our energy.
Drink water
Water is stored in our muscles with carbohydrates. This is the
energy source for our muscles. When we need to produce energy, the
stored carbohydrates are used and water is released during the process.
We need water to make and release energy. Guess what happens
when we are dehydrated? We get fatigued easily. Water aids stamina and
performance, and it helps to ward of those muscle cramps during intense
exercise.
Eat a balanced diet
This means that for those of us who eat lots of protein, we
also need to eat enough fruits, veggies and grains. And for those of us
who are vegetarians, it is important to get enough protein, iron,
calcium, B12, and Vitamin D. Supplements, sports bars and sports drinks
are not a substitute for real food.
Eat wisely
I call this being choosy about what kind of calories we eat.
If I want a tough workout, I will choose a nutrient-dense food over a
junk food. Of course, there is always room for a little junk -- I
recommend no more than 10% of our total daily calories (that's about
200 calories for most of us).
So, if we want to look good, feel energetic, and perform well,
let's "feed our muscles." Have we eaten enough carbohydrates; eaten
often enough; eaten wisely and had enough water? If the answer is yes,
we're off to a good start.

Want energy? Time your
eating and exercise
By Deborah
Shulman, Ph.D.
For Active.com 10/3/2003
"To give me energy." This is the usual response when I ask why
someone has eaten an energy bar or other food in the hour or so before
starting exercise.
In fact, the opposite is true. Eating an hour or even half an
hour before exercise is likely to make you feel tired and sluggish.
Twenty-five years ago, if a food or drink label proclaimed
"high energy," it would have sounded a death knell for that product. In
contemporary times though, people interpret that to mean that it will
give them high energy.
Red Bull drinks proudly display that they are high-energy
drinks. Sports bars are high-energy foods. Consequently, people eat or
drink them so they have high energy during exercise.
In the nutrition world, "high energy" is synonymous with "high
calorie." The way that the body deals with high calorie, particularly
high sugar, is by releasing insulin. Insulin is a storage hormone. When
you eat a high-calorie, high-sugar food an hour before exercise, you
will start exercise with high insulin levels.
This has two important results. First, it will change how you
perceive exercise. You feel sluggish and it feels hard. This is called
the rating of perceived exertion, or RPE. Your RPE is higher when you
start exercise with high insulin levels.
Second, you will burn a lower amount of fat for fuel. Insulin
lowers fat removal from the fat deposits and reduces fat metabolism
inside the muscle. Consequently, you rely more on carbohydrate for
energy.
Obviously, if you are trying to increase fat metabolism, it is
counterproductive to eat an hour or half an hour before exercise.
In general, during the day, it is better to time your last
meal or snack to be two hours before the start of exercise. If you wait
too long, however -- say, three or four hours after eating -- you'll
spend the whole exercise session hungry and fantasizing about food.
In fact, the best time to exercise is after an overnight fast.
At his time, blood levels of fat, growth hormone and testosterone are
all high. Under these conditions, fat metabolism will be at its
highest. Even better if you've had some coffee beforehand.
Those who have low fasting blood sugar in the morning may want
to eat a banana, a sports gel or some juice within five minutes of
starting exercise. You know who you are: you feel dizzy and shaky in
the morning until you've had something to eat. If you eat a small
amount a few minutes before starting, you won't get a substantive
insulin response.
Instead of eating before exercise, eat within 30 minutes of
finishing your exercise session. It is common for people to make the
mistake of not eating after exercise, either because they think the
increased metabolic rate will help them lose weight or just because
they're not hungry. In reality, during exercise you are breaking down
protein from the muscles, liver and kidney. This catabolic state
persists after exercise.
The more intense the exercise -- such as a heavy strength
training session at the gym or an interval workout at the track -- or
the longer the exercise lasted, the more muscle breakdown will occur.
This when insulin is your friend. Insulin is a growth hormone
and stops muscle breakdown. This is the best time to get larger doses
of carbohydrate. Your glycogen storage tanks will be low and the
combination of insulin and carbohydrate will refill them to be ready
for the next exercise session and will help your muscles grow.

Soccer: 7
nutrition myths
By Dr. Don
Kirkendall
For Active.com, 10/24/2003
Think nutrition is an easy topic?
See if you have the answers to these myths common in soccer.
1. Your performance in a game is not affected
by what you eat
You would think this is true, from reading the scientific
literature on just what soccer players eat. Nutritional recalls from
the 1970s to the present show that soccer players choose a diet that is
around 40% carbohydrates, 40% fat and 20% protein.
Virtually every study on athletic performance, be it a team
sport or an individual endurance sport, shows that a diet rich in
carbohydrates improves running performance. The more carbohydrates you
eat, the more and faster you run, especially late in the game.
What is discouraging is that in the very early '70s, the
Swedes showed that soccer players with low muscle fuel (glycogen) walk
about 50% of the game. And that was 30 years ago. What might be even
more discouraging is that over half of a national team in the 1994
World Cup thought food had nothing to do with their game. Players eat
what is put in front of them.
2. Sports drinks are just a product of
marketing; they are no better than water
No question that water is well understood by the active
public. The days of fluid restriction during sports are long gone. But
researchers have been looking at improving on water ever since the
advent of Gatorade. The timing, volume, temperature and components of
sports drink have been under continual study.
For example, a drink does no good if it stays in the stomach,
so the concentration of sugars is limited. A drink does no good if it
doesn't get from the small intestine into the blood, so there is an
optimal concentration of salt in the drink. And a drink isn't all that
effective if it doesn't stay in the body -- meaning that the volume of
drink and salt concentration, again, are critical.
Plain water doesn't have these advantages. A well-formulated
drink has the proper concentrations of sugars, salts, and
micronutrients, making it more effective than water alone.
3. All sports drinks are alike, so just buy
any of them
A lot of people think this, and the marketing of different
drinks can lead to this perception. But a close look at labels will
show vastly different drinks.
To start with, there are basically three completely different
types of drinks: fluid replenishment drinks, carbohydrate replenishment
drinks and energy drinks.
Fluid replenishment drinks are formulated to provide
optimal concentrations of sugars and salts, leading to rapid absorption
and retention of fluids in order to prevent dehydration and improve
performance.
Carbohydrate replenishment drinks are designed to
provide a fast source of carbohydrates that are rapidly absorbed by the
intestines. These can be used during a game for extra fuel as well as
right after play to start storing energy for the next day or game. The
best drinks have a little protein in them that speeds the uptake and
deposit of fuel into the muscle.
Energy drinks are highly caffeinated drinks that
deliver a small bump in energy due to caffeine's effect on the central
nervous system, not by adding any more fuel to the muscles. Plus,
caffeine is a diuretic, so it can increase urine volume, and any urine
loss of water during exercise is not good.
4. It doesn't matter what players eat after
games
I go to games and tournaments and see some of the worst
post-game feedings possible: soda, sweet drinks in soft packaging,
potato chips, other salty snacks, chocolate, fries. You've seen it.
The smart team supplies food that will start refilling the
muscles with carbohydrates at just the time that the muscles are most
ready to receive a fresh supply of fuel; the first hour to two after
exercise. And that food probably doesn't come in a bag.
A good supply of carbohydrates is needed, and it can come from
a carbohydrate replenishment drink or other high-glycemic foods like
bagels with jam/jelly, the ingredients for "chex mix" (not the premixed
boxes from the store, but the ingredients minus the oil and toasting),
pretzels, raisins (or other dried fruit). This is even more critical
between tournament games when time is even shorter.
5. All athletes get enough protein from what
they eat, so there's no need to look for other sources
While most every survey of the athletic diet shows that they
get all the protein they need from food, there is a problem. The vast
majority of protein is consumed in conjunction with fat. Marbled meat,
ground beef, fried chicken in the skin all are examples of protein that
is combined with lots of fat.
Red meat should be trimmed of fat, ground beef should be very
lean, chicken should have the skin removed. But one place protein is
often lacking is the immediate post-exercise meal. A little protein
helps in storing new fuel in the muscles faster than when there is no
protein. You can try to figure out a protein source (NOT from a fast
food chain) or simply buy one of the carbohydrate replenishment drinks
that contain protein.
6. I just coach; what the players eat is their
problem
While I have already stated that most all studies show that
players are not eating properly, there is an implicit question. Who
tells the athlete what to eat?
There have been plenty of surveys asking where athletes get
their information and the top two sources are the coach and teammates.
Now, from what we know, teammates are probably pretty unreliable. That
leaves the coach as the primary source of information. But should the
coach tell the player or the parents?
As the player eats what is put in front of them, that means
the parents are now the assistant coach in charge of fuel. They need to
know what to serve and when to serve it. Your new assistant may think
the various versions of the Atkins diet are good for themselves, but
those high-protein diets do the athlete no good when it comes to
providing fuel. Make sure your parents know the facts.
7. Your body is the best indicator of when to
drink
Now, that is true ... if you are a donkey, or a dog. The thirst
mechanism of humans isn't as good.
In fact, the human thirst mechanism doesn't even kick in until
you have lost about 2% of your body weight from sweating; a level where
performance decrement begins to become evident.
Drink early (before play), every 15 - 20 minutes during play,
and at halftime. Put water bottles along the sidelines, in both goals,
supply during stoppages. Remember that playing in the cold is also
dehydrating, so don't forget to push fluids even in cold weather.
There are likely more myths coaches, players and parents may
be following, but by following some of the guidelines mentioned here
will put your team at a significant advantage over the opposition.

Soccer
recovery: Bounce back faster after games
By Dr. Don Kirkendall
For Active.com, 10/24/2003
A soccer game can take a lot out of
you. When the final whistle blows, you are tired and sore, as expected.
But there are things you can do to bounce back quickly from games.
If you do them, you will have plenty of
energy and less leftover
muscle soreness by the time you practice again. If you don't do them,
you might stay sluggish and tender a lot longer.
Nutrition tips
Nutrition is an important part of
recovery. Nutritional recovery has
three components:
1. Rehydrate
During games, you sweat, and when you
sweat, you lose two important
substances that your body needs: water and selected minerals called
electrolytes (the stuff that makes sweat taste salty).
After games, you need to put these
substances back into your body,
in a little greater amounts than what you lost, sooner rather than
later. Until you rehydrate, your body will have a hard time keeping
cool and you may be prone to cramps and other problems.
Drinking water is just a start because it
does not contain
electrolytes. You're better off drinking a sports drink that has both
water and electrolytes. Try to drink at least 12 ounces of sports drink
in the first half-hour after the game ends. If it's a hot day, you may
need to drink even more.
The goal is to drink 1.5 pints for every
pound of weight lost over
the next 24 hours, before the next workout. Your urine should be no
darker than diluted lemonade.
2. Re-energize
You also burn a lot of energy fuel
during games. The main energy fuel
used in high-intensity sports like soccer is carbohydrate, which is
stored in your muscles, liver, and blood. The human body cannot story
very much carbohydrate. In a hard game, you can easily burn most of the
carbohydrate fuels in your body.
It's important to quickly replace this
carbohydrate. Until you do,
you will not have much energy. Most sports drinks contain
carbohydrates, so a convenient way to put energy back into your body is
to get it from the same place you get your water and electrolytes.
You can also get carbohydrate from foods
like fruits, breads,
starches and certain vegetables. Muscles refill with carbohydrate the
fastest immediately after exercise. Don't wait even as little as two
hours after exercise to start, as the rate of refilling becomes slower.
3. Rebuild
Your muscles are mostly made of
proteins. During games, some muscle
protein can be damaged; this is a main reason your legs feel sore and
weak after games. The good news is that your body is able to build new
muscle proteins at two to three times the normal rate after hard
exercise. All you need to do is supply the building blocks -- protein
-- to do the job in the first couple hours after the game is over.
Most sports drinks do not contain protein,
but some of the new ones
are adding it. Using a sport drink with protein is a good way to go
because of the convenience. You can get the water, electrolytes,
carbohydrate, and protein you need for recovery all from one source.
You can also get protein from foods like
meat and cheese, but these
foods also tend to be high in fat. When you eat a lot of fat after hard
exercise, or even too much protein, it takes longer for the nutrients
to get through your system to your muscles. This slows down the whole
recovery process.
So a sport drink that contains protein is
a better choice for
post-game nutrition. It contains everything your body needs to bounce
back fast, and without anything unneeded to get in the way.
Get a head start on
recovery
Using a sport drink with protein during
games is also a good idea
for two reasons. First, it will delay fatigue so you can play harder,
longer. In one experiment, athletes who drank a sports drink with
protein were able to exercise 24% longer than athletes who drank a
regular sports drink with no protein.
Second, the protein in the drink will
reduce the amount of muscle
protein breakdown that happens during the game, so there is less
rebuilding to be done afterward.
Other tips
While your muscles are still warm after a
game, stretch your
muscles. This will keep your blood flowing, helping to deliver
nutrients to your muscles and to clear away built-up wastes. You can
start drinking your sports drink while you stretch. Later in the day,
you can massage your legs using your thumbs, and this will also help
with blood flow.
After you play a game, try not to do
anything too strenuous for the
rest of the day. Your body requires rest in order to rehydrate,
re-energize, and rebuild the muscles. At the very least, be sure to get
plenty of sleep that night. During sleep, your body releases hormones
that help your muscles rebuild.
The recovery checklist
After every game:
Stretch while your muscles are still warm
Drink at least 12 oz. of a sports drink
containing protein
Monitor your urine color
Take it easy
Get a good night's sleep

Nutrition for
High School Athletes
Jacqueline Berning, Ph.D., R.D.
for Gatorade Sports Performance News 10/20/04
It's 8:45 p.m. on a school night and you and 35 athletes are loading on
a bus and heading back to school after an away game. Like many high
school athletes, your team didn't eat much before the game, and now
they are complaining that they're hungry and thirsty. As a coach, what
do you do? If you stop to eat on the way home, it will take another
hour to get there. Some of the athletes have homework to do, while
others need the extra sleep. If they don't eat, you know that they're
performance will suffer. Research shows that the decision you make will
have an impact on their ability to play and compete at their peak.
Recovering from Exercise
Not eating and drinking after competition and training can have
negative consequences on future athletic performance. For instance,
many coaches don't realize that it can take up to 36 hours to reload
the muscles of athletes who delay refueling their bodies. Such a delay
means that the athletes will not have the energy to meet the demands of
their sport. This is especially true for sports that have repeated
competitions such as tournament play in volleyball, basketball, soccer,
swimming or tennis. Parents and coaches need to recognize that an
intense game or a hard interval-training session can be just as
exhausting as running a marathon. Athletes who fail to refuel and/or
rehydrate during these activities will not have the optimal level of
energy the next day.
What to Eat
Carbohydrates
Muscle glycogen is the predominant fuel for energy during
exercise. As carbohydrate (glucose) is the primary source of muscle
glycogen, it is the most efficient source of energy for the body and
should make up approximately 60 percent of an athlete's diet. Depending
on the size of the athlete, that could amount to anywhere between 300
to more than 600 grams of carbohydrate each day. Carbohydrate-rich
foods include whole-grain breads, rice, pasta, fruits, vegetables and
sports drinks.
A carbohydrate snack consumed within 30 minutes after the competition
or practice will allow the body to start the recovery process faster.
In addition, players need to consume a carbohydrate-rich meal within
two hours after the recovery snack. This ensures that the muscles
continue to load with carbohydrate energy. For most high school
athletes, that means eating a meal soon after they get home from
competition or practice.
Protein
Protein also plays an important role in recovering from exercise.
Although carbohydrates are the primary source of energy for muscles,
consuming a small amount of protein shortly before or after exercise
may help the body recover from exercise in a different way, by
stimulating muscle repair and growth. This is backed by research that
found that adding protein to the recovery snack does not enhance the
muscle's ability to store energy, but instead, this extra protein is
used by the muscles to rebuild after exercise.
Note that it does not take large amounts of protein to get these
results. In fact, when athletes eat a combination of carbohydrates and
protein post-exercise, the carbohydrates are used to refill the muscles
with fuel, while the protein is used to help build and repair muscle
tissue.
What to Drink
Athletes need to replace the fluids they lose through sweat to fully
recover from exercise. The easiest way to do this is to consume a
sports drink, as sports drinks have flavor to encourage drinking and
contain electrolytes, such as sodium and potassium to maintain fluid
balance in the body. For instance, if an athlete drinks plain water and
does not eat any salty foods for the two hours after exercise, a
significant portion (25 to 50 percent) of what they drink will be
excreted as urine. However when an athlete rehydrates with a drink that
contains both sodium and potassium at the proper levels, then 65 to 80
percent of the fluid is retained by the body, helping to better
rehydrate the player.
A Coach's Story
Like many high school coaches, Chad Allen, who coaches the men's soccer
team at Douglas County High School in Castle Rock, Colorado, was
frustrated with the amount of time it took to feed his players after an
away game. While the Huskies' road trips are generally not over an
hour, stopping and feeding both the JV and Varsity teams added another
hour to the trip. A late afternoon game with travel and eating would
mean the bus did not arrive back at school until nearly 8:00 p.m.
To solve this problem, Chad implemented a strategy where parents
provide snacks for his players to consume on the way home, thus
eliminating the late trips and the problem of finding someplace to eat
after the game. The strategy is working, as he has noticed an
improvement in their performance. Their attitudes and moods are also
better. “It used to be that the kids were so hungry and thirsty that
they were quite irritable,” states Chad. “Now, we have the chance to
relax on the bus ride home, knowing we will have something healthy and
satisfying waiting for us to eat.”
Recovery Foods
Here's a sample of healthy foods to help athletes recover from
exercise:
- Sports drinks, like Gatorade Thirst Quencher
- Granola, energy or breakfast bars
- Bagels with peanut butter
- Sub sandwiches
- Crackers and cheese
- Burritos
- Fresh fruit like apples, bananas, oranges, grapes
- Vegetables such as carrots and celery
- Fruit smoothies (prepackaged)
- Rice cakes or trail mix
- Chocolate milk
- Animal crackers
Jacqueline Berning, Ph.D., R.D., is a nutrition consultant for the
Denver Broncos and Cleveland Indians as well as an associate professor
at the University of Colorado at Colorado Springs.
Quick Tips
- Athletes who fail to refuel and/or rehydrate during and after
activities will not have the optimal level of energy to play at the
same intensity the next day.
- To help in the recovery process, athletes should eat a
high-carbohydrate snack within 30 minutes after practice or competition
and a healthy meal two hours later.
- Carbohydrates are the most efficient source of energy for muscles
and they should make up approximately 60% of an athlete's diet.
- Sports drinks are an ideal way for athletes to rehydrate during
and after exercise.
- Having parents provide snacks and sports drinks for the bus trip
home after an away game is an excellent way to help athletes recover
from exercise.
Iron
Depletion: What you and your doctor need to know
by Jeff Hess
2005, Track & Field News
Before
you read on and decide that the following is either gospel or garbage,
let me suggest that it's neither. I'm addressing a medical issue, but
I'm just a high school track coach with degrees in English and Physical
Education. I have no medical training, but I have watched enough
athletes fade mysteriously from super-fitness to super-misery that I
started researching the possible causes.
More than anything else my questions led to the same answer: Iron.
Too
often we've attributed declining performances among high school
athletes (especially girls) to structural changes relating to puberty
or injuries resulting from overtraining. It's my belief-and I'm not
alone here-that a great many of those cases are caused directly from
iron depletion and could be remedied with proper nutrition and
supplementation.
But don't take my word for it. Do your own research; talk to you
coach,
parents and doctor and make an informed decision about what's right for
you. For starters though, you can continue reading and find out what
I've learned over the last few years.
Iron is a particularly important mineral for endurance athletes
due to its role in binding oxygen, which is circulated through the
lungs and to the working muscles. Unfortunately, our bodies absorb only
about 15% of the iron we ingest, and distance runners do just about
everything possible to deplete the iron that they do consume.
Iron is lost through sweat and gastrointestinal irritation. It is
temporarily lost through "footstrike hemolysis" (bursting blood cells
through foot impact with the ground). Iron absorption is inhibited by
calcium, coffee, tea, carbonated beverages and non-steroidal
anti-inflammatories (all that ibuprofen some of you swallow). Women
lose a substantial amount of iron through menstruation, making them
more susceptible to iron depletion, but it is a concern for all
distance runners-male and female.
Anemia, clinical iron deficiency, is not rare among runners, but
even
more common than iron deficiency is "iron depletion" due to low
ferritin stores. Ferritin is an iron-containing protein that is
primarily responsible for iron storage in the bone marrow. It is common
among distance runners to have acceptable hemoglobin and hematocrit
counts even when ferritin levels are severely depleted. For less active
people, low ferritin levels are much less significant and don't often
draw the attention of medical professionals.
However, the results of low ferritin levels for distance runners are
significant. While iron depletion rarely results in the general
lethargy associated with true iron-deficiency anemia, distance runners
with low ferritin will likely experience abnormal exhaustion, increased
blood lactate, slow recovery, declining performances, heavy legs,
muscular tightness, loss of motivation, and substantially increased
risk of injury. Does any of this sound familiar?
And there's more. Overuse injuries (the type of injuries
distance runners get) double with ferritin levels under 20 and triple
with levels under 12. I think it's safe to suggest that iron depletion
is rarely considered to be the root cause of these injuries. Instead we
focus on mileage, running surfaces, shoes and the other usual suspects.
If you were nodding your head thinking the previous symptoms sound like
a checklist of your most recent season, go get your serum ferritin
tested.
People within the medical and running communities have been
aware of anemia for decades, but the prevalence and severe impact of
iron depletion (low ferritin) is still far too much of a secret. The
normal range for serum ferritin levels depends on whom you talk to. I
have read everything from 50-150 nanograms per milliliter (ng/ml) to
10-300 ng/ml. However, we know that the lower the ferritin level, even
within the "normal" range, the more likely a person is iron depleted.
Virtually all female distance runners who have been training for a year
or more are well below 50 ng/ml unless they take supplemental iron.
At South Eugene High School, we became aware of the consequences of
low
iron in the spring of 2001 when three of our female distance runners
all came back from blood tests with ferritin levels below 10 ng/ml. All
three had all run their best times two years before but had been
plagued with injuries and frustration since. During those two years,
they had multiple blood tests, but the doctors never checked their
serum ferritin levels.
Within four weeks of beginning an aggressive supplementation
program, all three felt substantially more energy while running; their
enthusiasm and joy for running returned, and they began to run much
faster. Within two months, their levels were between 35 and 55 ng/ml.
All three went on to compete collegiately and ran times far superior to
what they ran in high school.
Since that initial experience, we have suggested that all the
girls on the team have complete iron tests. Only five out of the dozens
who have been tested, have been within the acceptable range for serum
ferritin, and those five were either big meat eaters or had been taking
supplemental iron for years. Half of the girls tested have been below
12 ng/ml.
Most of those tests were conducted at the beginning of the year,
giving
the girls enough time to boost their levels by the end of the season.
It makes better sense to have everyone tested (boys and girls and
absolutely all vegetarians) long before the season begins, so that any
deficiencies can be addressed before the more strenuous training
begins. Obviously, the best attack against this problem is not allowing
it to occur in the first place. Those taking supplemental iron and
eating an iron rich diet will most likely never develop an iron
deficiency.
When a blood test reveals that iron supplementation is called
for, there are many options for correcting the deficiency. Begin by
increasing the amount of iron-rich foods and foods high in Vitamin C in
your diet, avoid caffeine with meals, use cast iron cookware, and
consider taking supplemental iron.
With our athletes, we have noticed significantly faster and more
dramatic results among those who are supplementing with ferrous sulfate
or ferrous gluconate elixir and ascorbic acid than with those who have
taken iron tablets. Obviously, this is something that should be
undertaken only after consulting with a physician, but many doctors
still appear to be unaware of the problem of iron depletion. You may
need to educate your doctor before your doctor can help you.
As a competitive distance runner, you should know about the
importance
of iron, but it's not a cure-all, and it should be a blame-all either.
I've had a few athletes develop instant cases of iron depletion the day
after a hard workout or a late night of homework. It doesn't work that
way. Iron consumption is only one piece of the big nutrition puzzle,
and nutrition is only one piece of the enormous
How-to-be-the-best-runner-I-can-be puzzle, but if you're truly devoted
to completing the enormous one, you might help yourself get there by
giving your doctor a vial of your well-pumped blood.

Feed your hungry jocks foods to fuel performance
By Barbara Mahany
Chicago Tribune
Posted: 06/07/2011 12:01:00 PM PDT
A scary thing happens in the kitchen when a kid, who used to
scarf down half the pantry and call it "just a snack," decides to
take up an uber-taxing sport. And then decides he is going to eat like the
pros.
You can:
A. Take out a second mortgage to cover the grocery bills or ...
B. Get smart, and make sure every bite counts.
We went with the latter when the lanky 6-foot-3 kid in our house decided to
become a varsity rower and put us to the test.
We turned to the sports nutritionist Harper's Bazaar calls "one of the
top 10 experts to help revamp your diet" -- and who counts among her
clients elite athletes and pros, including the Stanley Cup-winning Chicago
Blackhawks, the Miami Heat's Dexter Pittman and the Minnesota Twins' Jim Thome.
Julie Burns, founder of SportFuel Inc., and the mother of high-school-age
triplets, has long been a walking encyclopedia of supernutrition.
Here's her Gospel for Hungry Jocks (and those who feed them): "What we
tell athletes and kids: Eat foods that will rot and spoil, but eat them before
they do."
She explains: "Say you have a box of (sugary cereal) that you leave
over winter at some cabin in the woods. You come back the next summer, you can
still eat it. But with foods that rot, the reason they become not edible is
that they're alive and they have enzymes. What creates high performance is
clean protein, healthy fats and minimally processed carbohydrates with all the
nutrients and enzymes nature packaged with them."
Instead of grabbing a bagel, she says, scramble eggs and grab a bowl of
raspberries. You need the antioxidants and the protein.
"The truth is if we don't prepare to eat well, we'll eat poorly,"
she cautions.
She knows too well what kids will eat if they're at an all-day swim meet, or
a rowing regatta, and the booster club -- with best intentions -- hauls in a
groaning board of granola bars, PB&J and juice bottles.
"You want to make every bite count," she says. "So think
ahead, pack a cooler of real foods: hard-cooked eggs, plain yogurt, turkey
jerky, pumpkin seeds, nuts, and dried and fresh fruits."
Eat Like a Pro
Give these tips from Burns to your teen athletes and tell
them: No need to tackle all of 'em at once. Just take one at a time, and watch
what happens to your sports performance.
Consider grass-fed beef. It contains higher amounts of omega-3 fatty acids, GLA
(gamma-linolenic acid, an omega-6 fatty acid), vitamins A and E, and zinc,
essentials all.
Add a green drink (a fresh or powdered blend of an alphabet of fruits and
greens) to your daily regimen to boost your vegetable consumption.
Add lemon to water whenever possible; it helps to alkalize your body, which
makes you feel good.
Drink at least one 8-ounce cup of green tea each day. Its wonders are too long
to list.
Chow down on carbohydrates and some protein in liquid form -- whey with
colorful fruit juice and even coconut water -- as soon as possible after your
workout.
Brazil nuts will boost selenium intake and may have anti-cancer properties.
Colleges are beginning to put more emphasis on students' shut-eye
Published: Thursday, Sep. 13, 2012 - 12:00 am

As college students return to campus, they're showered in the usual handouts of coupons, condoms and credit cards.
But some schools are also giving students what a growing body of
research reveals could make a huge difference in their college careers:
ear plugs, sleep shades and napping lessons.
College health
officials are finally realizing that healthy sleep habits are a
potential miracle drug for much of what ails the famously frazzled
modern American college student: anxiety, depression, physical health
problems and – more than most students realize – academic troubles. Some
studies have found students getting adequate sleep average a full
letter grade higher than those who don't.
But adolescent
biorhythms make it hard enough for college students to get the sleep
they need, a recommended nine hours. On top of that, campus life turns
out to resemble a giant laboratory experiment designed for maximum sleep deprivation:
irregular schedules, newfound freedom, endless social interaction, loud
and crowded housing, late-night exercise and food washed down by booze,
coffee and energy drinks. Campuses pulsing with energy at midnight by
mid- afternoon resemble Zombie U, with students dozing in library
chairs, on yoga mats and even in coffee shops.
Technology isn't helping, with wireless Internet adding to the 24/7
distractions and students sleeping with their smartphones on. That
likely helps explain data showing college students got about eight hours
of sleep in the 1960s and '70s, seven by the '80s, and, according to
more recent surveys, closer to six these days.
Campaigning
recently, even President Barack Obama told some students at an Ohio
State University diner that he assumed "you guys have arranged it so you
don't have really early morning classes."
No such luck.
"Actually, I failed that," one student replied, telling the president he had one at 8 a.m. the next day.
Now, some counselors and health officials are trying to get the message out in creative ways. At tiny Hastings College
in Nebraska, student peer educators plop down a bed in the middle of
the student union, dress themselves in pajamas, and talk to passers-by
about sleep. Macalester College in Minnesota publishes a "nap map"
listing pros and cons of various campus snooze sites. And many schools
offer seminars on napping (basic lesson: short naps work best).
The University of Louisville
is even planning a campus-wide "flash nap" – think of a flash mob but
with sleeping, not dancing – later in the school year. ("We have to
arrange in it advance so our public safety folks know it's not an
epidemic of something," said director of health promotion Karen Newton).
Still,
given the scope of sleeping problems, what's surprising is that such
efforts are exceptional. Major, campus-wide campaigns appear rare or
nonexistent. Experts say professors (and doctors) aren't always good
sleep role models. As for deans and administrators, many seem hesitant
to tell parents who've just dropped $50,000 on tuition that the big push
on campus this year will be for everyone to sleep more.
While
awareness is growing, at most schools sleep efforts amount to a few
posters on campus or perhaps a few lines in a quickly forgotten talk
during orientation week. While about three-quarters of college students
have indicated occasional sleep problems,
the latest National College Health Assessment found about the same
proportion reported receiving no information from their school about
sleep (though it's possible, in their sleepiness, some forgot).
"The average student is functioning with a clinical sleep disorder," said Lee Ann Hamilton, assistant director of health promotion and preventive services at the University of Arizona,
describing research conducted on students there. They average about 6
1/2 hours per night (though students tend to over-report in such
surveys).
But sleep time and quality measurements declined over
the course of the academic year, while anxiety, depression and conflict
with family, friends and roommates all rose.
Hamilton's office has been sending students a "Snoozeletter" with sleep tips.
As
described by junior Sara Campbell, residence hall life at UA makes it
hard even for students trying to sleep – constant late-night chattering,
visitors coming and going, early morning cleaning crews. She aims to be
asleep by 12:30 a.m. or so, but was dumbfounded to find girls on her
hall regularly pulling all-nighters for papers and exams – basically
academic suicide, the research shows.
"Not to speak bad of them,
but a lot of them are freshmen and just decided to wait 'till the last
minute," she said. Her big challenge was managing with a roommate who
tries to keep earlier hours; this year the pair are moving off-campus
together where they'll have separate bedrooms.
Still, Campbell is
applying what she's learned about sleep as a psychology major. This
year, she's arranged her schedule to have classes and work start at 8
a.m. every day of the week. That will be tough, but commits her to
avoiding the destructive pattern that traps many college students –
getting up early one day, then sleeping late the next.
"Regularity
is key," Campbell said. "You can pick a schedule here and have a
different time to get up every day, but going to bed at a different time
every night, it wears on your body."
College mental health
professionals are increasingly asking students about sleep right away,
finding it's often the low-lying fruit for helping students with a range
of issues.
"When you find depression, even when you find anxiety,
when you scratch the surface 80 to 90 percent of the time you find a
sleep problem as well," said University of Delaware psychologist Brad
Wolgast.
Many students who think they have attention deficit hyperactivity disorder
are often just sleep-deprived. Some simple steps to improve "sleep
hygiene" are usually far preferable to prescribing drugs. (Wolgast is
also seeing more students who've been prescribed sleeping pills, which
he says usually harm sleep patterns more than help).
"On a campus
they're dealing with alcohol, cocaine, marijuana, Ritalin abuse, sexual
assault," Wolgast said. In comparison, sleep "looks like a small
problem. But the truth is if I could wave a magic wand and change
everybody's sleep, there would be fewer problems with pretty much
everything else."
But Wolgast and others don't have a magic wand,
and have concluded that nagging students, or fighting the campus
culture, is hopeless. Running napping classes – pitched as ways to help
students maximize their sleep – has proved a more effective pitch.
Students
also happily accept earplugs. Hastings, with just 1,200 students,
orders them in bulk from a manufacturing supply company and hands out
thousands, said Beth Littrell, director of campus health services.
The
guru of the college sleep crusade is James Maas, who over 48 years
taught more than 65,000 students in Cornell University's most popular
class – a sleep-focused version of introductory psychology. Maas
evangelized to his students and experimented on them as well, asking
them to wear sleep-monitoring headbands and showing them
magnetic-resonance images of the brains of sleep-deprived college
students.
"You can see that nothing is going on in their brains," Maas said. "Literally nothing."
Confronting
students with such photos, along with hard data on how sleep undermines
academic performance, is the most effective way to change behavior,
Maas said. Still, he'd like to see colleges do more: ending early
classes, sound-proofing and air-conditioning dorms, putting sleep
education into the curriculum.
The people most receptive to his
message on campus are usually coaches. A few years back, he made his
pitch to Cornell's basketball coach, who stopped morning practices. The
next year the Big Red became the first Ivy League team since 1979 to
advance to the Sweet 16 of the NCAA men's basketball tournament.
Sleep
efforts have paid off at a number of boarding schools. After Maas spoke
at the Deerfield Academy in Massachusetts in 2007, the school moved the
start of classes from 7:55 to 8:30 a.m., cut sports practices and
homework expectations 10 percent each, and got students back into dorms
earlier at night.
The results? Twenty percent fewer student visits
to the health center (in a bad flu year); 17 percent more students
taking time for a hot breakfast, and a record increase in GPA. Also,
several Deerfield sports teams enjoyed unexpectedly good years, thanks
to late-season surges.
Of course, boarding schools have more
control over students than colleges. But Deerfield Headmistress
Margarita Curtis said that's no excuse for higher education. She said
Deerfield's efforts worked because students bought into them.
"You
need to appeal to their intellect," she said. "They responded because
they saw that correlation. They saw if you get that extra hour of sleep,
this is what happens in your brain, what happened to that athlete."

25 Horrible Things That Happen If You Don't Get Enough Sleep
By Lauren F Friedman
February 15, 2014 11:30 PM
In our 24/7 culture, sleep loss is a major problem. Back in 1942, we averaged almost 8 hours of sleep a night —
now that's down to 6.8. (Seven to 9 hours per night are what's generally recommended.)
Almost 40% of Americans get less than 7 hours of sleep a night, a recent Gallup poll found, and an estimated 70 million Americans have a sleep disorder.
Everyone knows that it's important to get enough sleep — but you may
not realize just how many things can go wrong when you don't.
Here are 25 unfortunate risks of partial and total sleep deprivation, some more common than others.
1. Irritability
"Complaints of irritability and [emotional] volatility following
sleepless nights" are common, a team of Israeli researchers observed.
They put those complaints to the test by following a group of underslept
medical residents. The study found that the negative emotional effect
of disruptive events — things like being interrupted while in the middle
of doing something — were amplified by sleep loss.
Source: Sleep, 2005
2. Headaches
Scientists don't yet know exactly why sleep deprivation leads to
headaches — but it's a connection doctors have noticed for more than a
century. Migraines can be triggered by sleepless nights, and 36 to 58%
of people with sleep apnea wake up with "nondescript morning headaches."
Source: Headache, 2003; Headache, 2005
3. Inability to learn
Sleepiness has long been an issue among adolescents. One study of
middle school students found that "delaying school start times by one
hour, from roughly 7:30 to 8:30, increases standardized test scores by
at least 2 percentile points in math and 1 percentile point in reading."
But it's not just kids. Short-term memory is a crucial component of
learning, and sleep deprivation significantly impaired the ability of
adult volunteers to remember words they'd been shown the day before. In
another study, researchers found that while people tend to improve on a
task when they do it more than once, this isn't true if they are kept
awake after they try it the first time — even if they sleep again before
doing it again.
Source: Nature, 1999; Nature Neuroscience, 2000; Education Next, 2012
4. Weight gain
People who are underslept seem to have hormone imbalances that are
tied to increased appetite, more cravings for high-calorie foods, a
greater response to indulgent treats, and a dampened ability to control
their impulses — a very dangerous combination. It's true that you burn
more calories when awake, but not nearly enough to cancel out the many
excess calories you consume when exhausted.
Source: Journal of Clinical Endocrinology & Metabolism, 2012; PLOS Medicine, 2004; Nature Communications, 2013; PNAS, 2013
5. Poor vision
Sleep deprivation is associated with tunnel vision, double vision,
and dimness. The longer you are awake, the more visual errors you'll
encounter, and the more likely you are to experience outright
hallucinations.
Source: International Journal of Occupational Medicine and Environmental Health, 2010
6. Heart disease
When researchers kept people awake for 88 hours, their blood pressure
went up — no big surprise there. But even subjects who were allowed to
sleep for 4 hours a night had an elevated heart rate when compared to
those getting 8 hours. Concentrations of C-reactive protein, a marker of
heart disease risk, increased in those fully and partially deprived of
sleep.
Source: Journal of the American College of Cardiology, 2004; PLOS ONE, 2009; Sleep Medicine Reviews, 2012
7. Slowness
Your reaction time is severely impeded when you don't get enough
sleep. When researchers gave West Point cadets two tests that require
quick decision-making, some were allowed to sleep between the tests,
while others were not. Those who had slept did better the second time —
those who had not did worse, and their reactions slowed down. A study in
college athletes found similar results.
Source: Sleep, 2009; Asian Journal of Sports Medicine, 2012
8. Infection
You know that great thing your immune system does, where when you get
an open wound of some kind it doesn't always get infected immediately?
Prolonged sleep deprivation and even one night of sleeplessness can
impede your body's natural defenses against microorganisms.
Source: American Journal of Physiology, 1993; The FASEB Journal, 1996
9. Economic risk-taking
Planning to make some changes to your portfolio? You might want to
make sure you're well-rested. "A single night of sleep deprivation
evoked a strategy shift during risky decision making such that healthy
human volunteers moved from defending against losses to seeking
increased gains," researchers concluded.
Source: The Journal of Neuroscience, 2011
10. Overproduction of urine
When people sleep, the body slows down its normal urine production.
This is why most people don't have to pee in the night as much as they
do during the day. But when someone is sleep deprived, this normal
slowdown doesn't happen, leading to what researchers call "excess
nocturnal urine production." This condition may be linked to bed wetting
in children and, in adults, it's tied to what's called nocturia — the
need to use the bathroom many times during the night.
Source: American Journal of Physiology, 2010; American Journal of Physiology, 2012
11. Distractedness
Having trouble paying attention to what you're reading or listening
to? Struggling with anything that requires you to truly focus?
"Attention tasks appear to be particularly sensitive to sleep loss,"
researchers have noted. If you want to stay alert and attentive, sleep
is a requirement. Otherwise, you enter "an unstable state that
fluctuates within seconds and that cannot be characterized as either
fully awake or asleep," and your ability to pay attention is variable at
best.
Source: Archives of Italian Biology, 2001; Seminars in Neurology, 2009
12. Less effective vaccines
Vaccines work by spurring your body to create antibodies against a
specific virus. But when you don't sleep, your immune system is
compromised, and this doesn't work quite as well. In one small study, 19
people were vaccinated against Hepatitis A. Ten of them got 8 hours of
sleep the following night, while the rest pulled an all-nighter. Four
weeks later, those who had slept normally had levels of Hepatitis A
antibodies almost twice as high as those who'd been kept awake.
Another study found that a sleepless night did not have a long-term
effect on immunity after a flu vaccine, it concludes that the effect
might be specific to certain diseases. "Sleep should be considered an
essential factor contributing to the success of vaccination," the Hep A
researchers wrote.
Source: Psychosomatic Medicine, 2003; Journal of Immunology, 2011; BMC Immunology, 2012
13. Impaired speech
Severe sleep deprivation might make you sound like a bumbling idiot —
much like having way too much to drink. "Volunteers kept awake for 36
hours showed a tendency to use word repetitions and clichés; they spoke
monotonously, slowly, [and] indistinctly," one study noted. "They were
not able to properly express and verbalize their thoughts."
Source: Sleep, 1997; International Journal of Occupational Medicine and Environmental Health, 2010
14. Colds
If you're wondering why you're sick all the time and seem to pick up
every bug that travels around the office, it's probably because you're
not getting enough sleep. When a group of 153 people were exposed to a
common cold, those who had gotten less than 7 hours of sleep in the two
weeks prior were almost 3 times more likely to get sick than those who'd
had 8 or more hours of sleep. How well you sleep is also a factor –
those who had spent 92% of their time in bed actually asleep were 5.5
times more likely to catch a cold than those who had been peacefully
slumbering 98-100% of the time they were in bed.
Source: Archives of Internal Medicine, 2009
15. Gastrointestinal problems
One in 250 Americans suffer from Inflammatory Bowel Disease (IBD),
and sleep deficiencies make its symptoms much worse. Regular sleep loss
also makes you more likely to develop both IBD and inflammatory bowel
syndrome, which affects an estimated 10-15% of people in the U.S. And
patients with Crohn's disease were twice as likely to experience a
relapse when they weren't getting enough sleep.
Source: World Journal of Gastroenterology, 2013
16. Car accidents
Drowsy driving is often compared to drunk driving: You really
shouldn't do either. "Motor vehicle accidents related to fatigue,
drowsy driving, and falling asleep at the wheel are particularly common,
but often underestimated," one review concluded. Pilots, truck drivers,
medical residents, and others required to stay awake for long periods
of time "show an increased risk of crashes or near misses due to sleep
deprivation."
Source: Seminars in Neurology, 2009
17. Depleted sex drive
Testosterone is an important component of sexual drive and desire in
both women and men. Sleeping increases testosterone levels, while being
awake decreases them. Sleep deprivation and disturbed sleep,
consequently, are associated with reduced libido and sexual dysfunction,
and people suffering from sleep apnea are at particular risk.
Source: American Journal of Obstetrics and Gynecology, 2007; Behavioral Brain Research, 2009; Journal of Sexual Medicine, 2009; Sleep Medicine, 2010; Brain Research, 2011
18. Pain
People in pain — especially those suffering from chronic pain — tend
not to get enough sleep. This makes sense: Pain can wake you up in the
night and make it hard to fall asleep in the first place. But recently,
researchers have begun to suspect that sleep deprivation may actually
cause pain or at least increase people's sensitivity to pain. One study
found that after research subjects were kept awake all night, their pain
threshold — the amount of painful stimulus they were able to endure —
was lower.
Source: Journal of Sleep Research, 2001; Sleep Medicine Reviews, 2006
19. Diabetes
Being awake when your body wants you to be asleep messes with your
metabolism, which in turn increases your risk for insulin resistance
(often called "pre-diabetes") and type 2 diabetes. "Interventions to
extend sleep duration may reduce diabetes risk," one study in
adolescents concluded. And four large studies in adults found a strong
association — though not a cause-effect relationship — between regular
sleep loss and the risk of developing diabetes, even after controlling
for other habits that might be relevant.
Source: Journal of Applied Physiology, 2005; Sleep, 2012; Annals of Internal Medicine, 2012
20. Sloppiness
Most people notice that when they're sleepy, they're not at the top
of their game. One study found that one sleepless night contributed to a
20-32% increase in the number of errors made by surgeons. People
playing sports that require precision — shooting, sailing, cycling, etc.
— also make more mistakes when they've been awake for extended periods
of time.
Source: The Lancet, 1998; Physiology & Behavior, 2007
21. Cancer
Scientists are just beginning to investigate the relationship between
sleep and cancer, and different kinds of cancer behave differently. But
since disrupted circadian rhythm and reduced immunity are direct
results of sleep deprivation, it's no surprise that preliminary research
seems to indicate that people who don't get enough sleep are at
increased risk for developing certain kinds of cancer, most notably
colon and breast cancers.
Source: Journal of the National Cancer Institute, 2003; Pathologie-biologie, 2003; Cancer, 2011; AAOHN Journal, 2011
22. Memory problems
Sleep disruptions in the elderly can lead to structural changes in
the brain that are associated with impaired long-term memory — and
sleep-related memory deficits have been observed in the general adult
population as well. As early as 1924, researchers noticed that people
who slept more forgot less. Poor sleep and not enough of it have also
been linked to higher levels of β-Amyloid, a biomarker for Alzheimer's.
Source: Cell Signal, 2012; Nature Neuroscience, 2013; JAMA Neurology, 2013
23. Genetic disruption
A 2013 study shed some light on why sleep is tied to so many
different aspects of our health and wellness. Poor sleep actually
disrupts normal genetic activity. After one week of sleeping less than 6
hours per night, researchers found that more than 700 genes were not
behaving normally, including some that help govern immune and stress
responses.
Some genes that typically cycle
according to a daily (circadian) pattern stopped doing so, while others
that don't normally follow a daily pattern began doing so. What does
this mean? Just one week of less-than-ideal sleep is enough to make some
of your genetic activity go haywire.
Source: Proceedings of the National Academy of Sciences, 2013
24. Unhappiness and depression
In a classic study led by Nobel
Prize-winning psychologist Daniel Kahneman, a group of 909 working women
kept detailed logs of their moods and day-to-day activities. While
differences in income up to $60,000 had little effect on happiness, a
poor night's sleep was one of two factors that could ruin the following
day's mood. (The other was tight deadlines at work.)
Another study reported higher marital happiness among women with more
peaceful sleep, although it's hard to say whether happy people sleep
better, better sleep makes people happier, or — most likely — some
combination of the two. Insomniacs are also twice as likely to develop
depression, and preliminary research suggests that treating sleep problems may successfully treat depressive symptoms.
Source: Science, 2004; Behavioral Sleep Medicine, 2009; Journal of Affective Disorders, 2011
25. Death
Many health problems are
associated with sleep deprivation and poor sleep, but here's the big
one: People who consistently do not get 7-8 hours of sleep are more
likely to die during a given time period. Put more simply: We all die
eventually, but sleeping too little — or even too much — is associated
with a higher risk of dying sooner than you otherwise might.
