Abstract
Research with obese populations has shown an improvement in body composition and increased resting metabolic rate with the supplementation of pyruvate and dihydroxyacetone. PURPOSE: To observe any body composition changes in competitive Division I collegiate anaerobic athletes during a 3-week double-blind supplementation period. METHODS: Twelve anaerobically-trained athletes (9 females and 3 males) volunteered to participate in the study where they were randomly assigned to a Calcium Pyruvate (CP) group (5 g/day) or Placebo group (PL). This study period occurred during the athletes' off-season resistance exercise program. RESULTS: Both groups were similar in all measured variables prior to a 3-week supplementation period. Body weight, BMI, resting metabolic rate and percent fat (determined by hydrostatic weighing) did not differ between the two groups following the 3-week supplementation period. Lower body muscular strength and upper and lower body muscular endurance exhibited significant improvements during the study period, however no significant effect of pyruvate supplementation was noted in the CP group. CONCLUSION: The results of this study suggest that 3 weeks of supplementation of CP in Division I anaerobically trained athletes will not result in positive body composition, resting metabolic rate, or muscular strength and endurance improvements.Table: No Caption Available.
