Effects of Graded Protein Intake and Resistance Training on Body Composition in Older Adults

This clinical trial is intended to evaluate the effects of protein intake graded to resistance training volume over a 10-week period on macroscopic skeletal muscle adaptations and body composition. Briefly, all participants will complete a progressive resistance training protocol for 10 weeks, with one group consuming a constant amount of total daily protein (RDA of 0.8g/kg/day) to serve as an active comparator. The alternative group will consume total daily protein and protein supplement in a graded manner designed to increase as overall training volume increases. Protein intake and resistance training protocols are described in full elsewhere. The investigators hypothesize that the graded protein intake group will see larger benefits to skeletal muscle function, size, and body composition than the active comparator.
