Abstract
The metabolic cost of circuit weight training was determined in a group of 20 men and 20 women, 17-36 yr of age, who volunteered to participate in this study. Performing 3 circuits (10 stations/circuit), using a work (30-s) to rest (15-s) ratio of 2:1, and a total exercise time of 22.5 min, the energy expenditure was highly related to body wt [BW] (r = 0.84 and r = 0.67 for men and women, respectively). The average gross energy expenditure was 539.7 and 367.5 kcal/h (9.0 and 6.1 kcal/min) for the men and women, respectively, but was 7.0 and 6.0 kcal/kg .cntdot. h when expressed relative to BW, and 8.1 and 8.2 kcal/kg (LBW) .cntdot. min when expressed relative to lean body weight [LBW]. Thus, when body composition was considered, there were essentially no differences in the energy expenditure for males and females.
