HARGREAVES, M., D. L. COSTILL, W. J. FINK, D. S. KING, and R. A. FIELDING. Effect of pre-exercise carbohydrate feedings on endurance cycling performance. Med. Sci. Sports Exerc., Vol. 19, No. 1, pp. 33-36, 1987. Six men were studied to compare the effects of pre-exercise carbohydrate feedings on endurance performance and muscle glycogen utilization during prolonged exercise. Trials consisted of a cycling ride to exhaustion at 75% maximal oxygen uptake preceded by the ingestion of either 75 g of glucose in 350 ml of water (GLU), 75 g of fructose in 350 ml of water (FRU), or 350 ml of an artificially sweetened and flavored placebo (CON). No differences were observed between trials for oxygen u..
