Brief Summary:
Stimulating overnight muscle protein synthesis, might augment muscle hypertrophy, increase mitochondrial mass, and/or improve muscle tissue repair. The goal of this proposal will be to provide further insight into the responsiveness of the muscle protein synthetic machinery to food intake in relation to age.
