EFFECT OF CREATINE SUPPLEMENTATION ON BODY COMPOSITION, STRENGTH, AND MUSCULAR ENDURANCE IN RESISTANCE TRAINED MALES

796 The purpose of this study was to determine the effect of two forms of Cr supplementation on body composition, strength, and muscle endurance. Thirty-five males (age = 19-26 yrs) with at least two years of strength training experience were tested on three occasions [pre-test (T-1), after 3 wks (T-2), and after 6 wks (T-3)] for 1-RM bench press, 1-RM leg press, repetitions-to-fatigue on a seated preacher bar curl, and body composition(via skinfolds). Subjects were divided into matched groups based on strength: Cr monohydrate (CrM, n = 11), Cr phosphate (CrP, n = 9), and placebo (PL, n = 14). Supplemented subjects followed a loading dosage (5 g 4X/day for 3 days) with maintenance dosage (5 g 2X/day) for remainder of the study. At T-3, both the CrM and CrP groups made significant increases in 1-RM bench press and LBM compared to the PL group, although the supplemented groups did not differ. TableTableOral supplementation with either CrP or CrM may be more effective in increasing strength and LBM than resistance training alone.
