Resistance exercises are commonly
used by sportsmen and trainers to increase strength, muscle mass, and fat-free
mass. The aim of this study is to investigate the effects of moderate-intensity
circuit resistance training on resting metabolic rate and body composition. 16
moderately active male subjects were voluntarily participated in this study and
the subjects were randomly assigned into either training (n=8, 25.1±1.3 years)
or control (n=8, 24.8±1.4 years) group. The moderate-intensity circuit resistance
training group followed a 12-week exercise program while the control group had
no resistance training. The subjects’ resting metabolic rates and body
composition assessments were performed at the beginning of the study and at the
end of the 12-week training period as pre- and post-tests. Statistical analyses
conducted by using paired samples t-test
showed that there were no significant differences (p>.05) in the resting
metabolic rates, heart rates and respiratory exchange ratios between the
training and control groups. At the end of the 12-week training period there
was a significant increase (p<.05)
in fat-free mass (2.5%) and a significant decrease (p<.05) in fat mass
(-8.5%) and body fat percentage (-8.9%) of the training group. No significant
differences were observed in the control group. Bone mineral density and body
weight values were not statistically different in any group, either. The
results showed that the 12-week moderate-intensity circuit strength training
had no significant effect on resting metabolic rate but body composition values
of the training group were improved.
