Ohyama, T., Fujieda, Y., Sugiura, K., Yamauchi, H., Hanaki, A., & Kuroda, I. (2002). Creatine supplementation could control reduction of performance in 60m running sprints among Japanese male athletes. Medicine and Science in Sports and Exercise, 34(5), Supplement abstract 809.

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 60-m sprinting with five minutes of rest between each repetition. Tests were performed before and after the supplementation period.

The creatine group performed better in the test set after supplementation. Performance deterioration was prevented.

Implication. Creatine supplementation could prevent performance deterioration in repeated sprint runs.
