No caffinated beverages for players. (Note that caffeine is a
restricted substance per the International Olympic Committee.)
Timing Your Pre-activity Meals
The rule of thumb for eating before exercise is to allow 4 hours
for a big meal (about 1,200 calories), 2 hours for a light meal
(about 600 calories), and an hour or less for a snack (about 300
calories). Sample carbohydrate-rich menus:
| Large Meal |
Light Meal |
Snack |
| 2 large bagels |
2 c
spaghetti |
1 medium banana |
| 2 tbsp
peanut butter |
1/2 c
tomato sauce |
1 pkg instant oatmeal |
| 2 tbsp jam |
8 oz
low-fat milk |
8 oz low-fat milk |
| 8 oz fruit
yogurt |

| 16 oz
orange juice |

Pre-Game Nutrition:
- Right before an
athletic competition: Players should have a light meal
or snack prior to arriving at games. In the morning, toast
and fruit, such as a banana are excellent, as is a pure
fruit juice. (the juice is even better if diluted 50% with
water for additional hydration.) Eat items that are easily
digestible, and try to eat shortly after waking. Avoid heavy
or greasy foods like bacon, home fries, doughnuts, and
cheese steaks. These take longer to digest and may have a
negative effect on performance.
AS AN ALTERNATIVE.............
- For early morning competition and no time to have a full
meal at least 3 hours before the competition, the best
choice is a nutrition drink that has a higher protein to
carb ratio. Good choices are the pre-mixed canned drinks
(e.g. Myoplex protein shakes, MET RX protein
shakes) These shakes come in different flavors and are best
when served cold. They usually have between 200 and 300
calories and because they are in liquid form are digested
quickly and easily distributed into the bloodstream. You can
always bring a six pack when you are traveling and just put
them in ice when you arrive at a hotel, or keep them in a
cooler. Also bring some straws for easy consumption. One
of these an hour before and right after each game can be
beneficial.
- For those having difficulty maintaining their weight, a
high calorie count drink can also be beneficial. Slim
Fast provides nutritional benefit without excessive
calories. Another choice is Boost or Ensure
that has a high protein count.
- Day before or night before competition (should be
eaten at least 3 hours before a
competition): Eat complex
carbohydrates (starches). Starchy foods such as pasta,
breads, cereals, potatoes, corn, peas and others provide a
major energy source to fuel your activities. These foods are
also a source of fiber, vitamins and minerals. Keep protein
and fat intakes low since these slow digestion.
- Avoid bulky foods. They
may stimulate bowel movements. Bulky foods include raw
fruits and vegetables, dry beans and peas and popcorn.
- Avoid gas-forming foods
such as vegetables from the cabbage family and cooked dry
beans.
- Eat slowly and chew well.
- Fruit juice or water rather than soda, always! The
juice is even better if diluted 50% with water for
additional hydration. Drink water to be adequately
hydrated. One suggestion is to drink 2 cups of cool water
1-2 hours before the event. Follow this by drinking
additional fluid 15 minutes before the event.
- Avoid drastic changes in
your normal diet routine immediately prior to competition.
Some athletes prefer to use favorite foods which may give
them a psychological edge.
During Game Nutrition:
- Drink sufficient fluids to
stay hydrated during training and competition periods -
don't wait until you are thirsty to drink.
- There is a new product coming onto the market that may
be used in lieu of water in the water bottles during games.
It is called Accelerade. It has a 4 to 1 protein to
carb ratio and has been proven to increase performance and
endurance if consumed during competition (better than
Gatorade, Powerade or water.)
Post-Game Nutrition:
- Consume carbohydrate-rich
foods and beverages as soon as possible after competition.
They will replenish glycogen stores quickly and get the
athlete back into performance shape. Fruits, juices, high
carbohydrate drinks and pop are examples.
- Replace fluids that have
been lost. For every pound that is lost, drink 2 cups of
fluids.
- Replace any potassium or
sodium that has been lost during competition or training by
using foods. Fruits and vegetables are excellent sources of
potassium. Replace sodium by eating salty foods. If activity
has exceeded 2 hours and is vigorous, a sports beverage will
be helpful.
- Return to your normal high
carbohydrate diet at your next meal.
Packable Snacks:
So you won't go hungry if
you're traveling to a game, stash 1,000 calories of
tried-and-true food in your bag. (Never try new foods before an
important event.) You might even pack extra snacks for underfed
teammates. On game day you can add perishable items such as
yogurt, bagels, apples or other fresh fruit, or even a sandwich
or two. Some possibilities:
- Granola bars or energy
bars (about 200 calories each)
- Trail mix (about 200
calories per 1/2 cup)
- Toaster pastries (about
200 calories each)
- Dried fruit (150 calories
per 1.5-ounce box of raisins)
- Animal crackers (about 140
calories per 12 pieces)
- Juice boxes (100 to 150
calories per 8 ounces)
Candy? Research
suggests that candy doesn't hurt most people's sports
performance. In one study, reported in the March 1987 Journal
of Applied Physiology, athletes who ate a big breakfast 4
hours before and a candy bar 5 minutes before hard exercise
improved 20% during the exercise test compared with when they
ate nothing. The results of the study also suggest that just
candy and no breakfast before exercise improved performance 10%
in comparison with eating nothing. Snickers Bars are a
good choice.
Some people are sensitive to
pre-exercise sugar, however, and have a rebound blood-sugar low
that makes them feel weak. Hence, the safest bet is to eat the
candy within 5 to 10 minutes of starting activity. This span is
too short for the body to respond. (Or, eat the candy more than
45 minutes before exercise to allow insulin levels to drop.)
Candy is better than nothing,
but it's not premium fuel. It's better to eat a more wholesome
snack like cereal, a banana or apple, yogurt, or pretzels and
juice. The urge for a quick energy fix is a sign you've eaten
too little food earlier in the day. To prevent cravings, eat a
hearty breakfast and lunch.

Drinks
and Sports Beverages for Athletes
Perspiration and exertion
deplete the body of fluids necessary for an optimal performance
and lead to dehydration and hyperthermia (over heating). It is
important to drink plenty of cool water, at least a half a cup
of water every 20 minutes of exercise. Adding a teaspoon of
sugar, a little fruit juice or a small amount of powdered drink
mix flavors plain water and may encourage fluid intake.
For the calorie conscious:
A teaspoon of sugar, has only 15 calories* per teaspoon. *Note:
Like all carbohydrates, sugar really has 4 calories per gram,
and there are 4 grams to a teaspoon. The FDA's 1993 food
labeling regulations require rounding to 15 calories on consumer
packages.
Usually there is no need to
worry about replacing carbohydrates unless the exercise lasts
over 90 minutes and is hard and continuous. When this happens,
drinking a sports drink or other beverage with some sugar in it
will fuel and water to the muscles being exercised.
Make a homemade sports drink
by mixing no more than 4 teaspoon of sugar, 1/4 teaspoon of salt
and some flavoring (like a teaspoon of lemon juice) in 8 ounces
of water.
The main benefit sports drinks
provide is hydration, which is why water is their most important
component. Dehydration both decreases performance and is
potentially life-threatening. Regular water intake is essential
during exercise.
The second ingredient sports
drinks contribute is carbohydrates, usually in the form of
sugars (glucose, fructose, and sucrose) or short-chain starches
(maltodextrins). Muscles use carbohydrates as their fuel of
preference, and carbohydrates in sports drinks help replace
carbohydrates that are burned during exercise. During prolonged
exercise bouts (90 minutes and longer), sports drinks do a
better job than plain water in delaying fatigue and prolonging
endurance. Research has shown that mixtures of the previously
mentioned carbohydrates are more quickly absorbed than a single
sugar, and that the total concentration of carbohydrates should
not exceed 8% (that equals about 19 grams or 75 calories of
carbohydrates per 8 ounces) for optimal absorption rate.
The next most important
component of sports drinks is the electrolyte mineral sodium,
which actually plays several important roles in sports drinks.
Sodium enhances fluid absorption in the gut (this is aided by
glucose in the drink), helps to maintain plasma volume, replaces
sodium lost in sweat, improves the palatability of the drink
(which increases intake), and stimulates the thirst mechanism
(which also increases intake). Although other minerals are also
lost in sweat (such as potassium), the amounts lost are so small
that their presence is not necessary in sports drinks, and their
levels can be replaced after exercise with a normal diet.
Sports drinks also contain
coloring and flavoring agents and often a little citric acid to
add tartness to the taste. These enhance palatability, which
means we'll drink more. That's really more important than it
seems, because the best sports drink is no good unless it gets
inside the athlete.
One more item deserves mention:
drink sports beverages cold; fluids that are about 40 degrees F.
are better absorbed than warm fluids.
High-carbohydrate drinks are
designed for post-exercise carbohydrate replacement -- after
you've already worked on rehydrating with a sports drink.
Virtually any high-carbohydrate source works well: soft drinks,
juices, solid foods, etc., so there's no reason to limit
ourselves to the high-carbohydrate sports drinks.
As for protein drinks and
powders, these are the oldest and stalest player in the sports
nutrition world. Consuming more dietary protein does not equal
more muscle protein. Actually, endurance athletes have more of a
need for dietary protein than weight lifters, but the truth is
that dietary protein is virtually never the limiting factor for
muscle growth and recovery in American athletes (that is folks
who eat a Western-world type diet). High protein products tend
to be a waste of money, but they aren't likely to physically
harm us.
