Document Summary
The pre-athletic event meal: readily digestible foods, should contribute to energy and fluid requirements, meals high in carbohydrates and low in lipids and proteins, three to four hours to digest and absorb the meal. Is consumed 3 to 4 hours before the event: contains 150 to 300 grams of carbohydrates, contains little fat, contains little fiber. Liquid meals: high in carbohydrate, supply fluids, rapidly digestible, can be used for day-long events, supplement calorie intake in those with difficultly maintaining body weight. Nutrition bars: high protein content, approximately 25 g of carbohydrates, may contain dietary supplements, should not substitute for normal food intake. Nutrition powders and drinks: high protein content, contain vitamins, minerals, and other dietary supplements, come in powdered form, contain fewer calories per serving than nutrition bars. If simple sugars are consumed, they should be consumed at least 60 minutes prior to exercise: fructose absorbs more slowly compared with glucose or sucrose, risk of gastrointestinal distress.
