CREATINE DOES NOT ACT DURING THE CREATINE LOADING PERIOD

Laks, D. M., Duarte, J. S., Alves, L. A., Neves, C. E., & Santos, E. L. (2004). Power output response during loading creatine supplementation period. Medicine and Science in Sports and Exercise, 36(5), Supplement abstract 2299.

This study investigated the power output during a creatine supplement loading period. It evaluated the peak power output, mean power output, power output variation, and total work done during the loading period. Males (N = 10) were divided in two groups - creatine and placebo, taking 4 5gm/day of creatine or maltodextrine, respectively. After a familiarization test, Ss completed a modified 60-s Wingate test on four alternate days. Testing was over seven days with 48 hours of rest between each test.

Peak power output, mean power output, and total work performed showed a non-significant decrease over the seven days. The amount of decrease was slightly less in the creatine group than in the placebo group.

Implication. Power output does not increase during a creatine supplement loading period.
