Fujieda, Y., Ohyama, T., Sugiura, K., & Yamauchi, H. (2002). Six-day creatine loading could improve anaerobic performance of repetitive maximal exercise in Japanese athletes. Medicine and Science in Sports and Exercise, 34(5), Supplement abstract 808.

Japanese male college athletes (N = 14) were assigned to a creatine supplement or placebo group. Ss supplemented creatine (4 x 5 g creatine plus 2.5 g dextrin) or placebo (4 x 7.5 g dextrin) daily for six days. Testing consisted of five repetitions of 7-s maximal cycle pedaling with five minutes of rest between each repetition. Tests were performed before and after the supplementation period.

The creatine group significantly improved in performance with each successive repetition, whereas the placebo group did not. As repetitions were completed, more of the total repeat was improved.

Implication. Creatine supplementation improved explosive cycling performance and the duration of the improvement within each trial.
