Eating Before Competing
Nancy Clark, MS, RD
Many casual exercisers and competitive athletes believe
they should avoid food for several hours before they exercise
or compete. Others wonder if they should snack, perhaps
on an energy bar before a soccer game. And a few are so
nervous that even the thought of food is nauseating.
Whatever your concerns, experimenting with some of the following
preactivity strategies and finding what works best for you
can give you top energy and performance.
Is it bad to eat before exercising or competing? Doesn't
the food just sit undigested?
As long as your activity is moderate (at a pace you can
maintain for more than 30 minutes), your body can digest
food during exercise. Preactivity eating can help you significantly
by supplying energy for sustained exercise and preventing
the lightheadedness, fatigue, and indecisiveness that can
result from low blood sugar. The food you eat 5 minutes
to 4 hours before activity helps fuel your muscles and brain,
and it can help you perform better.
For a few people whose activity is moderately paced, eating
causes gastric upset or intestinal problems. If you have
these difficulties, you simply have to learn from experience
the preexercise eating plan that works best for you.
With intense activities like rowing, sprinting, or speed
skating, blood flow is diverted from the stomach to the
working muscles. If you'll be exercising or competing intensely,
you'll probably want to allow about 4 hours between eating
and the event. That's the time needed for a typical meal
to empty from the stomach. Otherwise, you may have discomfort
or even nausea.
What can I do before a 10 am soccer game?
Carbohydrates are very important for maintaining normal
blood sugar (the fuel used by the brain) and glycogen (the
fuel used by the muscles). Because your blood sugar drops
as you sleep, you need to replenish the depleted stores
or your morning performance could suffer.
Plan to eat a carbohydrate-based breakfast between 6 am
and 8 am; then, if you're still tired, go back to bed. Cereal,
bread, fruit, and fruit juice are excellent choices that
may help you concentrate better and respond more quickly
during that morning soccer game. Or, be sure to eat extra
food the day before: Have an extra-big dinner that's low
in fat and a substantial bedtime meal or snack. You'll have
a better chance of maintaining a high energy level the next
morning.
I get so nervous before a competition that I can't even
think about eating. What can I do?
Plan to eat several hours before activity, and eat familiar
foods that won't cause a surprise stomach upset. Many athletes
like oatmeal or other hot or cold cereals with low-fat milk.
Other soothing, carbohydrate-rich choices are bagels with
a little light cream cheese, yogurt, pancakes, or French
toast. If the thought of solid food turns your stomach,
you may prefer a meal replacement drink.
Any fuel is better than none, so try to consume at least
300 to 500 calories.
I'm so hungry in the afternoon that I buy a candy bar for
quick energy before working out. Does sugar hurt sports
performance?
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.
Some people are sensitive to preexercise 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.
When we travel to a 7 pm event, I often miss dinner. Any
suggestions?
Traveling athletes commonly struggle to fuel properly. Sometimes
they simply run out of time. Or they get to the event and
expect food to be provided--and find nothing left, or nothing
appealing or appropriate.
Your responsibility is to fuel yourself well throughout
game day. That means, for example, getting up early enough
to have a hearty pancake breakfast, eating a double serving
of pasta or two big sandwiches at lunch, drinking water
throughout the day for extra fluids, and making time for
a pregame dinner. The key: Plan ahead.
The best pregame meals are carbohydrate-based: for example,
spaghetti and tomato sauce (a little lean meat in the sauce
is fine); or potatoes or rice, vegetables, and dinner rolls
with a small serving of chicken or other protein-rich food
(see "Timing Your Preactivity Meals," below).
As with any pregame meal, choose foods that you know will
settle comfortably and digest easily. Be sure to limit fried
and high-fat foods like burgers, fried chicken, french fries,
and nachos. These and similar fast foods take a long time
to digest.
Too many athletes--most of whom know they should have a
carbohydrate-rich pregame dinner--fail to plan meals into
their schedule. If this sounds familiar, pack emergency
food in your gym bag (see "Packable Snacks," below).
Snacks are better than nothing, but a good meal helps mentally,
if not physically. Rather than regret improper eating, make
time to eat well--perhaps even planning a mandatory team
dinner--so you'll have energy to enhance your sports performance.
Timing Your Preactivity 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 |
|
|
|
Packable Snacks
So you won't go hungry if you're traveling to a night
game, stash 1,000 calories of tried-and-true food in your
gym 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)
