Effect of creatine supplementation on body composition and performance: a meta-analysis
Branch JD
Published in International Journal of Sport Nutrition and Exercise Metabolism
Methodology
Meta-analysis of 100 randomized studies examining creatine supplementation effects on lean body mass and exercise performance across exercise modes and durations.
Key Findings
Creatine produced a significant positive effect size for lean body mass and for performance in short-duration, high-intensity tasks, with negligible effect for tasks lasting more than 150 seconds.
Conclusions
Creatine supplementation reliably improves lean mass and high-intensity, short-duration performance.
Limitations
Older analysis with heterogeneous protocols; few female or older-adult participants; publication bias possible.
Supplements Studied
Creatine produced a significant positive effect size for lean body mass and short-duration, high-intensity performance.
Outcomes Measured
Creatine produced a significant positive effect size for lean body mass and short-duration, high-intensity performance.
