White, M. T., & Faria, I. E. (1999). The effects of oral creatine supplementation on anaerobic power in trained cyclists. Medicine and Science in Sports and Exercise, 31(5), Supplement abstract 367.

The effect of oral creatine supplementation on anaerobic power during multiple sprint cycle bouts was investigated. Well-trained male cyclists were assigned to a placebo (N = 4) or a creatine (N = 6) group. Creatine was consumed (15 g/day) for five days before the initial pre-test assessment (six maximal 30-s sprints with three minutes of active recovery between each effort). Supplementation lasted 28 days. The carbohydrate placebo was 34 g/d while creatine was 34 g/d CHO plus 3 g/d creatine.

Post-supplementation testing showed no differences between the groups for total power, mean power, or percent power decline.

Implication. Creatine supplementation, of the levels used in this study, does not provide an ergogenic effect on repeated anaerobic power output in well-trained cyclists.
