| Description | Purpose: This study examined the effects of anaerobic exercise on resting metabolic rate (RMR) and body composition and determined whether 3 months of regular resistance training changed these parameters in groupofmen (n = 8), aged 27-34 with sedentary life style. Methods: During the initial measurements, thevaluesof RMR, body composition and exercise test were obtained. In addition, five-day nutrition alintake and record of physical activity were completed. After the initial measurements, participants performed supervised resistance training, for 12 weeks, 3 d/wk. The combination of free weights and exercise machine was used for training. During the first 6 weeks of training program, subjects performed 10-12 repetitions per set, 2-3 sets per exercise movement, 2 exercises per muscle group. The resistance was set on each exercise so that each subject became fatigued between 10 and 12 repetitions. Duringthe second 6 weeks, subjects performed 8-10 repetitions per set, 3 sets per exercise movement, 2-3 exercises per muscle group. The resistance was set on each exercise so that each subject became fatigued between 8 and 10 repetitions. The output measurements were obtained after 6 and 12 weeks of regular physical activity. The monitored parameters were mainly differences in value of resting metabolic rate and body composition. Data of RMR were collected using the air analyzer MetalyzerCortex 3B in the Laboratory of Sports Medicine, Faculty of Sports Studies in Brno. Results: All subjects had increases in the values of relative RMR from baseline to 3 months of regular physical activity( 22,9kcal/kg/d, s = 2,79 to 26,8 kcal/kg/d, s = 3,51). Conclusions: Regular resistance training in healthy, previously sedentary adult men increases the value of RMR. The results suggest that resting metabolic rate is a dynamic parameter, responding to changes in lifestyle. |
