    Cermak NM, Res PT, de Groot LC, Saris WH, van Loon LJ

    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

    Whey Protein
    Compound

    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.
