Muscle Growth Following a Resistance Training Program in Men and Women Consuming Protein Supplements

Completed · Not applicable

Conditions studied: Skeletal Muscle Growth

In brief

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.
