Sarcopenia Clinical Trials

Muscle health declines during aging. One factor that may impact muscle health is the community of bacteria that live in our intestines, but studies aimed at improving muscle health by targeting the gut in older adults are sparse. The primary goal of this study is to use a diet that is enriched in soluble fiber, which is exclusively utilized by gut bacteria to make substances that can impact muscle health, to improve muscle-related measures 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. Read Less
