High Performance Nutrition for Athletes
Prepared by Coach Lee Pantas
To reach
your highest potential as an athlete, all of your body
systems must be perfectly tuned. Nothing is more important to
your well-being and ability to perform than good nutrition. The
best training in the world will not help you perform at a high
level if you do not eat right. Eating the right foods helps you
maintain desirable body weight, stay physically fit, and
establish optimum nerve-muscle reflexes. Without the right
foods, even physical conditioning and expert coaching aren't
enough to push you to your best. Good nutrition must be a key
part of your training program if you are to succeed.
There is
no one "miracle food" or supplement that can supply all of your
nutritional needs. Certain foods supply mainly proteins, other
foods contain vitamins and minerals, and so on. The key to
balancing your diet is to combine different foods so that
nutrient deficiencies in some foods are made up by nutrient
surpluses in others. Eating a variety of foods is the secret.
The
nutrients--the proteins, carbohydrates, fats, vitamins,
minerals, and water--are teammates that work together to provide
good nutrition. Just as each team member carries out different
tasks during a game, each nutrient performs specific functions
in your body. A lack of just one nutrient is a disadvantage to
your body. Your body needs all these nutrients all of the time,
so the foods you eat should supply them every day.
Just
because you are not hungry does not necessarily mean that your
body has all the nutrients it needs. You can fill up on foods
that contain mostly carbohydrates and fats, but your body still
has basic needs for proteins, minerals, and vitamins.
Listed
below are the 5 main food groups. As a track athlete you should
eat a balanced selection from all five groups. Recommended
minimum servings per day are given for each group:
Milk, Yogurt, and Cheese
Group (3-5
servings daily) 1 serving is
an 8 ounce glass of milk,
8 ounces of yogurt or 1 1/2 ounces
of natural, unprocessed cheese.
Meat, Poultry, Fish, Beans, Eggs, and Nuts Group
(3 to 4 servings daily)
1 serving is
3 ounces of lean, cooked meat, 2
eggs, 1 cup of cooked dry beans, peas, or lentils or 4
tablespoons of peanut butter.
Vegetable Group (3 to
5 servings daily). 1 serving
is 1/2 cup of cooked
vegetables, 1/2 cup of chopped raw vegetables, 1 cup of leafy
raw vegetables such as lettuce or spinach, or 1 glass (6 ounces)
of juice.
Fruit Group (3 to 5 servings daily).
1 serving is
1 whole fruit such as a medium
apple, banana, or orange, 1/2 grapefruit, 1 glass (6 ounces) of
juice, 1/2 cup (4 ounces) of berries, 1/2 cup (4 ounces) of
cooked or canned fruit or 1/4 cup of dried fruit
Bread, Cereal, Rice, and Pasta
(6 to 11 servings daily). 1
serving is 1 slice of
bread, 1/2 hamburger bun or English muffin, one1 small roll,
biscuit, or muffin, 3 to 4 small or 2 large crackers, 1/2 cup
cooked cereal, rice, or pasta or 1 ounce ready-to-eat breakfast
cereal.
Because of
their rapid growth and development and higher levels of physical
activity, teen athletes should eat the higher levels of servings
recommended from each food group. An active track athlete could
easily eat eleven servings of breads/cereals and four to five
servings of the other food groups each day. Some athletes may
even need more than the maximum servings recommended. Eating the
maximum number of servings recommended from all five-food groups
provides about 3,000 calories.
In no instance should you
eat less than the minimum servings for any food group.
You need the minimum servings to supply a base level of
essential nutrients and calories required for good health.
Consuming the minimum servings listed above will supply about
1,600 calories, which is the minimum a teen girl should take in.
Teen boys need at least 2,000 calories a day and thus need more
than the minimums given.
Athletes
need plenty of starchy foods because, along with proper
training, these foods cause muscle and liver cells to store
glycogen. Glycogen is a vital energy source for most sports.
When muscle cells run out of glycogen, muscle fatigue sets in
and performance suffers. Foods high in starch include: pastas,
spaghetti, noodles, ravioli, beans, rice, potatoes, carrots,
peas, corn, sweet potatoes, bread, bagels, muffins, pancakes,
waffles and cereals.
Unfortunately, many girl athletes think of starchy foods as
"fattening" and cut out breads, cereals, and starchy vegetables.
The results are predictable: low glycogen, low energy, and poor
performance. The girl athlete who wants top performance must eat
starchy food so that she goes into an event with glycogen
reserves. Starchy foods are not fattening in themselves. Eating
more than the body needs and not exercising is the main cause of
obesity. America is currently experiencing an epidemic of
overweight kids who eat too much junk food and do not exercise.
However, the girl athlete who is training properly shouldn't
worry about extra weight from starchy foods.
High Energy Foods For Athletes
These are
some of the best foods you can eat as an athlete, the ones that
improve athletic performance. They are of particular importance
in your diet. Make sure you include them.
Bananas: The perfect
snack-One of the highest sources of potassium.
Beef: Great source of zinc, high quality protein, iron and
creatine.
Beans-Legumes: High in protein and B Vitamins, important for
building protein
Broccoli: One of the best nutritional foods around. High in
Vitamin C, folic acid, calcium, magnesium and iron.
Brown Rice: Better for you than white rice.
Carrots and Carrot Juice: Most concentrated source of
beta-carotene
Cheese: Great source of calcium
Chicken: Another high quality protein source
Corn: High carbohydrate source
Dried Fruit: Concentrated sources of energy and good sources
of iron
Fig Bars: Strong carbohydrate punch and easy to eat
Grapes: Good source of boron, important in building strong
muscles and bones
Kiwi: High in vitamin C
Lentils: Good source of protein, complex carbohydrates, and
iron.
Milk: Absolutely essential for athletes. Great source of
vitamin D and calcium. The drink of choice for Marion Jones.
Oatmeal: Great source of fiber and carbohydrates.
Orange Juice: Vitamin C, potassium and more
Papaya: A treasure trove of nutrients
Pasta: Loaded with complex carbohydrates
Potato: Powerhouse of complex carbohydrates, potassium,
Vitamin C and iron
Salmon: High protein and rice source of important omega-3
fatty acids
Strawberries: Vitamin C and fiber
Water: 2 liters a day for athletes is a must!
Whole Grain Cereals. Complex carbohydrates. Chose whole
grain bread rather than white.
Yogurt: Another great source of all-important calcium.
Special Nutrient Needs of
Athletes:
Increased physical activity increases some of your food needs.
You require more energy, water, and possibly salt (sodium
chloride). An athletic teenage boy may need 5,000 calories a
day, compared to the 3,000 calories required daily by his
non-athletic friends. By taking extra servings of foods from all
food groups (particularly breads, cereals, vegetables, and
fruits), you can fill this increased energy need.
Salt needs
can be met by increased use of salt on foods. The use of salt
tablets is not recommended. Salt tablets can cause stomach
cramps. The tablets hold water in the stomach longer and can
actually cause water to be pulled back into the intestinal tract
and away from body tissues where the water is needed most.
What To
Eat Before A Game:
Before a
game, your digestive processes may be slowed down by your
keyed-up emotional state. To allow for this condition, you
should eat an easily digestible, balenced meal no later than
three hours before the contest. Avoid foods that contain
substantial amounts of fats or oils. Fats are more slowly
digested than other nutrients. Trying to compete with a high-fat
meal still in your stomach is a losing proposition. Meals high
in starches are better because they are digested more rapidly
than fats or oils. Make sure that your pre-game meal is a
balanced one containing all food groups.
Some
athletes like poached eggs, toast, and juice as a light pre-meet
meal. Some prefer breakfast cereal with milk, yogurt, a bagel or
toast, and juice. All-day events such as track meets present
special problems. Consuming several high-starch mini-meals or
snacks, accompanied by ample fluids, is a winning strategy for
these situations. Snacks you might consider bringing to the
all-day meet include Fig Bars (Allen Johnson’s favorite meet
snack is Fig Newtons), Powerbars, dried fruit, Granola Bars,
bananas, apples, oranges, grapes and other fruit, carrots,
peanut butter sandwiches. For the meet, stay away from candy,
chips and most of the junk food sold in convenience stores or in
the concession stand at the track! Bring your own high-energy
snacks! At all costs avoid sugary foods such as candy or honey
before a meet. Sweets can cause rapid swings in blood-sugar
levels and result in low blood sugar and less energy.
Keeping Energy Levels Up
Keeping
your energy levels up for peak performance isn't easy. It
doesn't just happen. High energy levels are the result of good
eating and exercise habits. If you don't pay attention to either
of these factors, your performance can suffer.
One of the
least-recognized nutrition problems of the young athlete is
simply not eating enough. Extracurricular activities may make
life so busy that you simply don't take the time to eat.
After-school practice sessions may be so exhausting that you
feel too tired to eat. But you must take the time to eat the
right foods. Don't let fatigue caused by poor eating hurt your
performance. Another problem of the young athlete is not eating
the right kinds of foods--particularly foods high in starch.
Eating a balanced diet that has plenty of starch keeps muscle
energy up.
Participating in sports can drastically increase your food
energy needs. Increased physical activity calls for more food
calories. Also, when you train, you increase muscle tissue
relative to fat tissue, and muscle tissue requires more calories
than fat tissue. Going out for sports can easily increase the
daily calorie needs of a teen athlete by 2,000 or more. A
teenage athlete on a track team may consume 5,000 or more
calories daily.
The amount
of food you need depends on your age, sex, weight, and activity
level. A larger athlete requires more calories that a smaller
one because more energy is needed to move more mass over the
same distance. You usually burn more calories in a practice
session than in actual competition because more total work is
usually done during practice. However, the rate at which
calories are burned for short periods of time may be greater
from short bursts of intense activity during competition.
Activity levels vary among sports as well as with the position
played in a sport.
The
glycogen stores you have available right before an event are the
result of how you've eaten and exercised for the past several
days. Glycogen stores in the body are increased by rest or light
levels of exercise and high levels of carbohydrates
(particularly starch) in the diet. Glycogen stores in the body
are lowered by high levels of exercise and low levels of starch
in the diet. Once glycogen stores are exhausted, it takes at
least two days to fully restore them. Although the pre-meet
meal can stabilize blood sugar levels and provide some energy,
don't look to the pre-meet meal to provide the bulk of your
energy for the meet. You should eat a nutritious, varied
diet containing plenty of starchy foods every day. Give starches
particular emphasis two days before the event.
Here are
some tips to help you keep your glycogen reserves
up--particularly before a soccer game:
-
Start
each day with a good breakfast. Cold cereal, milk, toast,
fruit, and/or fruit juice make an easy-to-fix, quick meal
that provides plenty of starch.
-
Select
meals that contain foods from all five-food groups. Our
bodies use nutrients more efficiently when they are consumed
together. Model your noon meal on one of the Main Meals
shown above.
-
Use
high-energy healthy snacks as another opportunity to power
up with starch--and don't forget that snack at bedtime. Cold
cereal with milk serves as a quick snack at any time. It can
be more than the "breakfast" of champions! And you don't
have to stop at one bowlful.
-
Give
starchy foods particular emphasis the days right before the
event by building the main meal around a high-starch entree
like spaghetti and meatballs. Make sure the other food
groups are also represented.
-
Decrease physical activity the day before and the day of the
event. Light practices directed by your coach are enough.
The day before or the day of the event is not the time to
organize a pickup game with your friends. Rest up!
-
Drink
plenty of fluids--even at mealtimes--to guard against
dehydration.
AFTER THE GAME
After the
game or practice session, much of the glycogen in your muscle
and liver tissue has been used up, and synthesis, or creation,
of new muscle protein slows. To promote glycogen recovery,
consume nutritious foods and drinks that are high in
carbohydrates and protein. When you eat the right foods, your
body can replace lost glycogen rapidly, and normal synthesis of
new proteins can resume.
Whole
foods like cereals, breads, and pastas with a glass of milk are
better for total recovery than pure carbohydrate supplements. A
mix of whole foods contains proteins, minerals, and vitamins in
addition to carbohydrates. You need these other nutrients along
with high levels of carbohydrates for a complete, rapid
recovery. . Remember, whole foods, such as breads and cereals,
when eaten with beverages like milk promote more rapid recovery
than pure carbohydrates alone.
To assist in total, rapid recovery, you
should consume nutritious foods and drinks as soon as you can
tolerate them after an event or workout. Ideally, you should eat
food within two hours afterward. However, if you can't tolerate
eating that soon, choose what's comfortable for you.
Young
athletes often have questions about foods high in fat and sugar,
such as candy, soda, and desserts. These foods are called "empty
calorie" foods because they're usually high in calories but
contain few nutrients. Don't eat many of these foods but they
are ok in moderation. Stay away from these foods on meet day.
Get your energy from foods that supply ample proteins, vitamins,
and minerals as well as calories.
Many
athletes mistakenly believe that high-sugar foods will give them
quick energy before a game or an event. High-sugar foods, such
as candy or honey, should be avoided before a game or an event.
Sweets can cause rapid swings in blood sugar, make you feel
tired, and decrease performance.
Hydration For Top Performance
Water lost
through sweating is not easily replaced. Low water-intake during
strenuous exercise leads to dehydration, which can lead to
fatigue, heatstroke, and death. Replacement water should
never be restricted during exercise. However, if you drink
too much water too quickly during increased physical activity,
you may become "waterlogged," an unpleasant condition that you
may already have experienced. Moderate amounts of cool water
taken frequently before, during, and after activity prevent this
problem. Six to eight ounces of fluid taken every fifteen to
twenty minutes during strenuous activity is about right for most
athletes.
There are many different commercial sports
drinks available. They contain varying kinds and amounts of
sugars and electrolytes. Whether they offer advantages over
plain water depends on the situation. Many times, plain water is
all that an athlete needs. When activities last an hour or more,
however, some sport drinks may offer advantages both for
carbohydrate and electrolyte replacement.
Water is a
basic necessity for all life. Without it, life can't exist. Even
when water is limited, living organisms suffer. You are no
exception. For young athletes like yourself, not enough water
means you can't do your best. It can even cause serious health
problems. Our blood circulates like an ocean within us. The
water in blood helps carry nutrients and energy to our body
cells. It also carries waste products away from our cells for
excretion from our body. Water helps regulate our body
temperature, too--an important factor for all of us.
As a young
athlete, you have a special need for water. Remember to
drink plenty of fluids, even if you aren't thirsty. A soccer
athlete in training needs at least 2 liters of water a day!!
Keep your fluid levels up! When you participate in a
sport like soccer, you burn a lot of food energy (called
calories). Some of that unleashed energy powers muscles. But
some of that energy is released as heat. Water keeps you from
overheating. Sweating and evaporation from the skin cools you
down. However, water is lost in the cooling process. That can be
dangerous if the water is not replenished. If you run low on
water, your body can overheat, like a car that is low on cooling
fluid. Losing just two percent of the body's water can hurt
performance. A five percent loss can cause heat exhaustion. A
seven percent to ten percent loss can result in heat stroke and
death. Dehydration can kill.
Young
athletes have a lot of growing to do. New muscle tissue must be
made. Bones need to grow rapidly. And with all of the physical
activity, some tissues need to be repaired. All of this
metabolic activity requires an abundance of nutrients and energy
carried to body tissues and waste products carried away. Water
allows all of this to happen. Water is vital for your body's
growth, repair, and physical activity.
Just
satisfying thirst is not enough!!
Thirst is
your body's signal that you need to drink water. By the time you
feel thirsty, you may have already lost one percent to two
percent of your water--and that's enough to hurt performance.
But just drinking enough to satisfy your thirst may not supply
your body's needs. If you drink only enough to satisfy your
thirst, your body may take up to 24 hours to fully rehydrate its
cells and regain maximum performance.
When you
participate in a sporting event or practice session, follow
these guidelines:
-
Don't
wait until you are thirsty before drinking water.
-
Drink
more than enough to satisfy your thirst.
-
Drink
more than you think you need before an event or practice to
make sure you are fully rehydrated.
Conditioned athletes need
more water--not less.
The conditioned athlete is
able to store and burn more energy in a shorter time. That means
your body releases more heat, requires more cooling, loses more
water, and needs more water to replenish its stores. Also, you
may have increased your sweating response, which means you lose
even more water. As an in-shape athlete, you need more water
than other people.
When you feel exhausted and hot during a
workout or game, drinking large amounts of water very rapidly
may cause discomfort or stomach cramps. But that is not a good
reason to restrict water. Drinking moderate amounts at frequent
intervals is the best strategy during competition or practice.
About one cup (six to eight
ounces) of cool water every 15 to 20 minutes during an activity
is about right for most athletes.
Some athletes can drink a bit more than this at each interval.
Cool water is best and helps absorb body heat. And it empties
from the stomach into the intestine at a fast rate, which allows
it to be absorbed rapidly into the body.
Most of
the weight you lose during an event or training session is water
lost through sweat. Of course, you lose some weight when your
body burns materials for energy. For example, the glycogen
stored in liver and muscle cells is used for energy, which
results in some weight loss. Some fat and protein is burned for
energy, too, and that results in additional weight loss.
However, most of the weight you lose during strenuous physical
activity is water lost through perspiration.
