Glycemic carbohydrates consumed with amino acids or protein right after exercise enhance muscle formation

Abstract

This review shows the importance of high-glycemic carbohydrates consumed together with protein in enhancing the exercise-induced muscle formation relative to timing of intake. Insulin, which increases in blood after glycemic carbohydrate ingestion, seems to effectively stimulate protein synthesis and inhibit protein degradation right after exercise rather than later. This presents a new aspect in nutrition: the importance of intake timing in addition to the composition and amount of nutrients. © 2003 International Life Sciences Institute.
