Vukovich, M. D., & Peeters, B. M. (1999). Effects of creatine supplementation on exercise performance: A meta-analytical review. Medicine and Science in Sports and Exercise, 31(5), Supplement abstract 1278.

A meta-analysis was performed on 31 published studies of creatine supplementation and measures of performance.

It was concluded that creatine supplementation results in a positive ergogenic effect that is more pronounced in athletes. The magnitude of performance improvements appears to be directly related to the length of the period of supplementation and favors relatively short-duration work. The effect on lactate metabolism during exercise appears to be small.

Implication. Creatine supplementation improves strength, power, and relatively short-duration work.
