Published in American Journal of Clinical Nutrition
Methodology
Meta-analysis of 22 randomised controlled trials comparing protein supplementation with placebo during prolonged resistance-type exercise training.
Key Findings
Protein supplementation increased fat-free mass gain by 0.69 kg and leg press strength by 13.5 kg compared with placebo.
Conclusions
Protein supplementation during resistance training produces small but consistent additional gains in lean mass and strength in young and older adults.
Limitations
Variable protein types and timing; limited number of trials in older women.
Supplements Studied
Protein supplementation increased fat-free mass gain by 0.69 kg and leg press strength by 13.5 kg compared with placebo.
Outcomes Measured
Protein supplementation augments the adaptive response of skeletal muscle to resistance-type exercise training.
Leg press strength increased by 13.5 kg more with protein supplementation than placebo.
