What to Eat Before an Athletic
Event
By Nancy Brinch, MS, RD, LSW
Knowing
what to eat before exercise, especially before competition, can
be tricky. On the one hand, the athlete needs adequate fuel available
during competition for peak performance. On the other hand, eating
the wrong foods prior to exercise can result in bloating, nausea,
and a sluggish feeling.
An athlete needs to eat to avoid hunger and low blood sugar during
exercise. The muscles and the brain need a constant supply of glucose
to function. If the blood sugar falls too low fatigue, light-headedness,
and poor mental functioning will result. Eating sufficient carbohydrate
a day or more before competition will increase the body's supply
of glycogen, the storage form of carbohydrate. This will provide
a continual supply of glucose during exercise. Food eaten within
an hour of competition also provides glucose to exercising muscles,
the brain and nervous system. Selecting the best foods to meet the
body's need for energy is crucial.
There is no magical meal that will work for all athletes. Every
athlete has individual food preferences and tolerances. The type
of exercise, level of intensity and time of day all influence optimal
food selection. The following guidelines will help an athlete make
the best food choices:
Eat adequate carbohydrate in the days leading up to competition.
This keeps the muscles fueled with glycogen stores. Glycogen breaks
down to glucose when the blood level of glucose drops. By eating
good sources of carbohydrate like bread, bagels, fruit, juices,
skim or 1 % milk, low-fat yogurt, pasta, potatoes, rice, cereal,
crackers, Graham crackers and fig Newtons throughout the day the
muscles will store glycogen.
Eat a pre-exercise meal. This won't increase glycogen stores,
but it will increase the blood glucose level to supply exercising
muscles with fuel. A good meal is high in carbohydrate, moderate
in protein and low in fat. Carbohydrates are digested quickly. Fat
takes longer to digest. Therefore the pre-exercise meal should be
low in fat. High-fat meals before an event can cause bloating and
indigestion. Timing is important when choosing what to eat.
4 hours or more before an event: The night before an event
eat a high-carbohydrate meal and drink lots of water. Four hours
or more before the event try these suggestions. Four hours leaves
enough time for the food to be digested and leave the stomach.
1. turkey sandwich and fruit
2. grilled chicken, potato and vegetable
3. scrambled eggs, toast, and juice
4. spaghetti and meat sauce
2 hours before an event: A light (200- 400 calories) carbohydrate
meal is easily
digested and provides glucose for exercising muscles. Drink plenty
of water. Why should you not eat a high-protein meal? Protein does
not provide quick energy. Excess protein increases water loss from
the body and can increase the risk of dehydration. Also, many high-protein
foods are also high in fat.
1. Cereal and skim or 1% milk
2. Bagel
3. Energy bar
4. Large banana and yogurt
1 hour or less before an event: Be careful with eating sugary
foods before an event. While most athletes perform well or even
improve their performance when they eat pre-exercise sweets, some
athletes experience a drop in blood sugar when they eat sweets 15
minutes to 2 hours before exercise. Eating sweets 5 to 10 minutes
prior to exercise is your best bet because the body will not have
enough time to produce excess insulin, the hormone that causes the
blood sugar to drop. Once you start exercising the body stops secreting
insulin.
1. Sports drink
2. Pretzels
3. Raisins
4. Yogurt
If your stomach becomes nervous before an event, a liquid meal might
be better tolerated. Liquid meals leave the stomach faster than
solid meals. Make a yogurt smoothie by blending:
1 cup vanilla yogurt
1 small banana
½ cup frozen berries
Some athletes find too much liquid in the stomach causes discomfort
that can cause nausea. It's always best to experiment with new foods
ahead of time to see how your body responds to them during exercise.
Stick with familiar foods before an event.
Always drink lots of fluids.
The day before an event drink an extra 4 to 8 glasses of fluid.
You should have to urinate frequently, and your urine should be
a clear lemonade color.
Up to 2 hours before an event drink 2 to 3 glasses of water. This
will give you adequate time to empty your bladder before the event.
5 - 10 minutes before the event drink another 1 -2 glasses of water.
Remember - hunger hurts your performance. What you eat as well as
when you eat can help you optimize your performance.
