Methodology
Randomized, double-blind trial using stable isotope tracers to measure myofibrillar and muscle connective protein synthesis rates after resistance exercise with collagen protein, whey protein or placebo.
Key Findings
Collagen protein ingestion did not increase muscle connective tissue protein synthesis rates above placebo, and whey was superior for myofibrillar synthesis.
Conclusions
Collagen protein does not augment muscle connective protein synthesis during post-exercise recovery.
Limitations
Acute mechanistic endpoint over hours rather than long-term structural or performance outcomes; young healthy males only.
Supplements Studied
Collagen protein ingestion did not increase muscle connective tissue protein synthesis rates above placebo.
Outcomes Measured
Collagen protein ingestion did not increase muscle connective tissue protein synthesis rates above placebo.
Collagen protein ingestion did not increase muscle connective tissue protein synthesis rates above placebo, and whey was superior for myofibrillar synthesis.
