Comparative Effects of Creatine Monohydrate and Creatine Hydrochloride Supplementation on Strength and Body Composition in Elite Team-Sport Athletes

This randomized controlled trial investigates the effects of Creatine Monohydrate (CrM) and Creatine Hydrochloride (Cr-HCl) on strength and body composition in elite team-sport athletes. Thirty-one male athletes were assigned to CrM (n=11), Cr-HCl (n=10), or placebo (n=10) groups for a six-week supplementation period. Performance metrics included one-repetition maximum (1RM) for bench press and squat, and body composition via DEXA. Both creatine groups demonstrated significant improvements in strength and fat-free mass compared to placebo (p < 0.01), with no significant differences between CrM and Cr-HCl. These findings support the efficacy of both forms as effective ergogenic aids.
