Muscle Growth and Development Following a 12-week Resistance Training Program in Men and Women Consuming Soy and Whey Protein Supplements
In Brief
A clinical study evaluating Whey protein supplement and Soy protein supplement for Skeletal Muscle Growth. Completed, enrolled 61 participants across 1 site.
Detailed 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.
