The effect of chromium picolinate on muscular strength and body composition in women athletes
Fifteen women softball athletes were randomly divided into 2 groups, the chromium treatment group (n = 8) and the placebo control group (n = 7) to examine the effect of chromium, in the form of chromium picolinate (CrPic) supplementation, on muscular strength, body composition (body weight, percent body fat, and lean body mass), and urinary excretion. The CrPic supplementation consisted of a 500 ug dosage taken once per day. All participants trained 3 times per week with 23 sets of 812 repetitions at 80% of 1 repetition maximum (1RM) using variable resistance machines and free weights. No significant (p < 0.05) differences in muscular strength or body composition were found after 6 weeks of resistance training. In addition, chromium excretion (g per 24 every hours) was examined and increased significantly with the treatment group after the 6-week period.
