Abstract
Ribeiro, B.G.; Burini, R.C. Determinant factors of glycogen resynthesis following exercise: nutritional issues. Nutrire: rev. Soc. Bras. Alim. Nutr.= J. Brazilian Soc. Food Nutr., São Paulo, SP., v.23, p. 79-91, jun., 2002.
Recovery after exercise poses an important challenge to the modern athlete. Important issues include restoration of liver and muscle glycogen stores. The synthesis of muscle glycogen following its depletion by exercise occurs in a biphasic manner. These primary stimulus regulate the glicose uptake for the skeletal muscular cell, the own muscular contraction, the insulin concentration and the carbohydrate bioavalability. Factors that seem to influence the rate of glycogen synthesis to the hours immediately following exercise include the time following exercise, the amount and frequency of carbohydrate consumption, the type and form of carbohydrate consumed and the presence of other macronutrients ingested at a meal following exercise. Rapid resynthesis of muscle glycogen stores is aided by the immediate intake of carbohydrate, 1 g.kg1 of body mass, particularly of high glycemic index carbohydrate foods, leadind to a total intake over 24 hours of 7 - 10 g.kg1 of body mass. Provided adequate carbohydrate is consumed it appears that the presence of others macronutrientes does not affect the rate of glycogen storage.
