The purpose of this project was to determine the effects of creatine supplementation on muscular power and work. Eighteen subjects (mixed male and female) volunteered to participate in this study and were randomly assigned to either the supplement (S) or the placebo (P) groups (N=9 per group). Prior to the supplement period, all subjects performed a concentric/eccentric maximal power output isokinetic test at 60°·sec-1 on the knee extensors of their dominant leg. This test was followed by a bilateral isotonic muscular fatigue test of the knee extensors (concentric/eccentric contractions) to exhaustion. Following the pre-test protocol, subjects were administered either 20 g/day creatine monohydrate (dissolved in a sports drink solution) or a placebo (sports drink solution with no creatine monohydrate) for 6 consecutive days. Post-testing occurred on day seven of the supplement/placebo period. No changes were observed in group P. All data is reported as means ± SD for group S. Table

These data indicate that supplementing with creatine monohydrate can be effective in improving muscular power and work.
