...five male and three female cyclists cycled in a steamy environment (34 degrees Centigrade, 55 per cent humidity) until they had dehydrated them-selves by about 2 per cent of body weight. After the exercise, the athletes ingested either a carbo-hydrate-electrolyte sports drink or else a standard meal comprised of 53 per cent carbohydrate, 28 percent fat, and 19 percent protein, along with water (at a volume 1.5-times greater than the amount actually lost during exercise).
Total urine output was significantly lower after the meal, compared with the sports drink, probably because of all the electrolytes (especially sodium and potassium) naturally found in the food, which helped hold water in the body. When only the sports drink was ingested, the subjects' body-water levels were still down by about 10 to 11 ounces six hours after the exercise had concluded, while the meal-and-water combination restored fluid balance to normal ('Restoration of Fluid Balance after Exercise-Induced Dehydration: Effects of Food and Fluid Intake,' European Journal of Applied Physiology, vol. 73, pp. 317-325, 1996). Obviously, combining good water intakes with consumption of electrolyte-rich foods can be a great way to rehydrate. -pponline.uk
MY COMMENT: Eating after a long workout does much more than restock muscle glycogen!
