Impact of circuit resistance training on body composition on young male

Abstract

The purpose of this study was to determine the effects of circuit type resistance training on body composition and bone status in young males. Twenty eight moderately active male volunteers were randomly assigned to 12 weeks of circuit resistance training (CRT) (n=15; 24.3±1.4 years) or control (C) (n=13; 24.8±2.1 years). Total body fat (%BF), fat mass (FM), fat-free mass (FFM), bone mineral content, and bone mineral density (BMD) measurements were performed with dual-energy X-ray absorptiometry. At the end of the 12-week training period, there was a decrease (p.05) in body weight or BMD. In C, no significant (p>.05) changes were observed. CRT bone mineral density values were significantly (p
