简要总结
The purpose of this study is to assess which amino acids are affecting acute muscle collagen synthesis in response to supplementation and exercise.
详细描述
This is a double-blinded, randomized controlled, parallel design study, with 3 treatment groups (placebo, collagen peptide, and essential amino acid). The study will involve 3 visits: a baseline testing/familiarization session, and 2 exercise trials which will include muscle biopsies, blood draws, and the infusion of a tracer isotope in order to measure muscle protein synthesis.
