Study 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.

Primary Outcome

assessed using dual energy x-ray absorptiometry (DEXA) scan for changes in lean body mass (kg)

Interventions

  • DIETARY_SUPPLEMENT Whey protein supplement
  • DIETARY_SUPPLEMENT Soy protein supplement
