The purpose of this investigation was to examine the effects of 6 wk of oral creatine supplementation during a periodized program of strength training on arm flexor, bench press and squat 1RM, and body composition. Eighteen college athletes volunteers with at least 1 year of weight training experience randomly assigned to two groups of creatine(Cr, n=9) and placebo(P, n=9) with no significant mean at pretest measures. Cr group received 20 g.d-1 of creatine for the first 6 d in 5-g doses, four times daily, followed by 5 g.d-1 for reminder of the study. Each 5-g dose was mixed with 500 mL of glucose solution. The P group received a placebo (starched, sucrose drink) following the exact protocol as the Cr group. All subjects’ resistance trained 3 d.Wk-1. Measurement of 1RM strength of arm flexors, bench press, and squat and body composition were made pre- and post-training after supplementation while monitoring dietary intakes. Results showed body mass and lean tissue mass increased to a greater extent with training in Cr compared to placebo group (p< 0.05). There were no significant changes in percent body fat for either group. Cr group demonstrated greater improvement in 1RM of squat, bench press and arm flexors than placebo group. These data suggest that creatine supplementation during strength training may be superior to training alone for enhancing muscular strength and body composition.
