Muscle Growth and Development Following a 12-week Resistance Training Program in Men and Women Consuming Soy and Whey Protein Supplements

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.
