Published in American Journal of Clinical Nutrition
Methodology
Double-blind randomised placebo-controlled trial of 20 g protein before and after each session during 12 weeks of resistance training in healthy elderly men.
Key Findings
Both groups gained muscle cross-sectional area and strength, with no significant difference between protein and placebo.
Conclusions
In elderly men consuming adequate habitual protein, timed protein supplementation adds no further hypertrophy beyond resistance training itself.
Limitations
Small sample; habitual protein intake already sufficient; healthy, non-sarcopenic participants.
Supplements Studied
Both groups gained muscle cross-sectional area and strength, with no significant difference between protein supplementation and placebo.
Outcomes Measured
Strength gains did not differ between protein and placebo in elderly men with adequate protein intake.
