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

DIETARY_SUPPLEMENT

Whey protein supplement

19 g whey protein isolate (contains 2 g leucine) was consumed daily by one intervention group.

DIETARY_SUPPLEMENT
