Summary

This study will compare short-term post-exercise muscle glycogen synthesis following combined galactose-glucose, glucose alone or galactose alone ingestion.

Detailed description

Lactose, the sugar contained within milk, consists of glucose and galactose. Post-exercise consumption of a carbohydrate mixture containing glucose with galactose has been shown to accelerate liver glycogen repletion as compared to glucose-only provision. However, the extent to which galactose-glucose combinations influence post-exercise muscle glycogen storage has yet to be determined. Therefore, this study will investigate whether short-term muscle glycogen storage after strenuous endurance exercise is enhanced by combined galactose-glucose or glucose only ingestion as compared to the ingestion of galactose alone.
