The problems of rehydration during exercise are addressed. Dehydration will reduce circulatory capacity, cooling and exercise efficiency and hence reduce athletic performance. However, athletes attempting to supplement fluid intake during performance commonly complain of gastrointestinal (GI) discomfort. Experiments are described investigating the relationship between GI function and fluid supplementation. The authors conclude that fluids should be taken early in the exercise period, before dehydration sets in.
