Study Summary
To conduct a randomized, double-blind, controlled clinical trial to determine the independent and combined effects of dietary conjugated linoleic acid (CLA) and vitamin D supplementation on anabolic signaling, the expression of growth regulatory factors, and muscle protein turnover in older adults.
Primary Outcome
A stable isotope labelled amino acid infusion, in conjunction with blood and muscle tissue sampling and mathematical modelling analysis will be used to measure post-absorptive muscle protein synthesis.
