Carbs, Carbs, Carbs

BY KATHLEEN WOOLF, PhD, RD//Special Correspondent

Swimmers, like most athletes, use carbohydrates as fuel during exercise. Unfortunately, the body only stores a limited amount of carbohydrate, and it can easily be depleted after a vigorous workout. To maximize your body’s carbohydrate stores, consume carbs before, during and after exercise.

Carbs Before Exercise
Before every practice or competition, include carbs as part of a pre-event meal to “top off” your muscle stores. Select foods that can be quickly digested and absorbed. Depending on the time of your pre-event meal, vary your meal patterns. When a pre-event meal occurs 4 hours before your event, consume foods such as a turkey sandwich, apple, oatmeal cookie and low-fat milk. If your pre-event meal occurs less than one hour before an event, limit your intake to a small amount of juice or fruit or a sports beverage. Research consistently supports that eating a pre-event meal improves performance. However, a single pre-event meal will not compensate for an overall poor training diet.

Carbs During Exercise
When exercise lasts more than an hour, carbs are recommended during exercise to provide additional fuel for your body. Carbohydrate intake during exercise allows athletes to exercise longer and harder. Consume 30 to 60 grams of carbs per hour during long duration exercise. To provide your body with 30 grams of carbs, choose 2 cups of a sports beverage or 1 medium banana or 3 large graham crackers.

Carbs After Exercise

Immediately after every practice or competition, consume carbohydrate-rich foods and beverages as part of your recovery. Choose fruit, 100% fruit juices, low-fat milk, cereal, sports beverages and bagels to replenish your carbohydrate stores so that you are ready for your next event. What you eat after a hard practice affects your ability to perform during your next workout.

Carbs Always

Because carbohydrates are the predominant fuel for most events, swimmers need to focus on a carbohydrate-rich diet. For optimal performance, make it a habit to consume high-carbohydrate meals and snacks, before, during and after exercise.
