The differences in MPS rates between whey and soy protein may be due to higher leucine content and more rapid leucinemia with whey.
Understanding the role of leucine may help in selecting protein sources for muscle health in the elderly.
StrongQualifiesmedium confidence
the higher leucine content and more rapid leucinemia with whey as opposed to soy may in part explain the observed differences in resting and post-exercise MPS between the two proteins.
Why this rating
The study design is robust as indicated in the abstract.
