Abstract

Supplementation of oral creatine is a popular practice among strength and power athletes. Little evidence exists, however, on creatine’s short-term performance effects in college-aged females. The purpose of this study was to examine the effects of short-term creatine supplementation on physical fitness measures of muscular strength, muscular endurance, and body composition in college aged females. A double-blinded randomized placebo controlled trial was used with n=10 college-aged females assigned to either creatine (n=5) or placebo (n=5) groups. Subjects underwent a 2-week resistance training program with treatments administered during week 2. Fitness measurements were taken at baseline, week 1 (pre-supplementation), and week 2 (post-supplementation). Significant group-by-trial interactions were seen for percent body fat (PBF), 1RM leg press (LP), 1RM bench press (BP), wall sit (WS), push-up (PU), plank, and vertical jump scores, with the creatine group exhibiting significantly (p’s<.05) greater improvement over control group on all measures. Results of this study show that short-term creatine supplementation may produce positive effects on physical fitness measures while taken during a resistance training program.
