10 young men will be recruited and be exposed to both WPH and WHEY supplementation. Each subject will undergo a metabolic stable isotope infusion study. Muscle biopsies will be obtained to measure markers of amino acid sensing (e.g., mTORC1 activation) via immunoblotting and to assess protein synthesis. This acute study will allow to determine whether low dose WPH supplementation will be an effective nutritional treatment to stimulate muscle protein synthesis in young adults. Importantly, this study will provide the necessary preliminary data to design future short and long-term clinical trials to improve muscle function and skeletal muscle mass in clinical populations.
