Summary

Soy and whey protein have different concentrations of leucine, an amino acid known to be a particularly potent simulator of muscle protein synthesis. The purpose of this study is to determine whether matching soy and whey protein supplements for leucine content instead of by total protein content would contribute to differences in strength increases and muscle growth in response to 12 wk of resistance training.

Conditions

• Skeletal Muscle Growth

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Whey protein supplement	19 g whey protein isolate (contains 2 g leucine) was consumed daily by one intervention group.
DIETARY_SUPPLEMENT	Soy protein supplement	26 g soy protein isolate (contains 2 g leucine) was consumed daily by the other intervention group.
