CREATINE INFLUENCES POWER OUTPUT IN INTERVAL EXERCISE SETS
Vole, J. S., Kraemer, W. J., Bush, J. A. Boetes, M., Incledon, T., Clark, K. L., & Lynch, J. M. (1997). Creatine supplementation enhances muscular performance during high-intensity resistance exercise. Journal of the American Dietetic Association, 97, 765-770.
The influence of one week of oral supplementation with creatine monohydrate on muscular performance during repeated sets of high-intensity resistance exercise was assessed. Active men were assigned to a creatine group (N = 7) and a placebo group (N = 7). Repeated bench press and jump squat exercises with low resistances were performed to exhaustion.
It was found that lifting performance was similar for both groups. Creatine supplementation resulted in significant improvement in peak power output during all sets of exercises. Post exercise lactates were only higher for bench presses but not jump squats in the creatine group. Creatine ingestion significantly increased the body mass/weight of the participants.
Implication. One week of creatine supplementation (25 gm/day) enhanced performance during repeated sets of specific exercises. Single performance measures of strength were not altered.
