Abstract
The purpose of this study was to examine the effects of 11 weeks of resistance exercise training on body composition, insulin resistance, growth hormone and insulin-like growth factor-1 of obese college male students. Twenty obese college male students were volunteered to participate in this study as subjects, and they were randomly assigned to either resistance exercise training group(n=10) or control group(n=10). The subjects in resistance exercise program for intensity of 65% 1RM, three times per week for 11 weeks, whereas subjects in control were asked to maintain their normal life pattern for the same intervention period. All subjects were asked not to change their physical activity pattern throughout the intervention period. Main results of the present study were as follows: 1) Weight, BMI and % body fat were significantly decreased in resistance exercise training group. 2) Insulin and insulin resistance were significantly decreased in resistance exercise training group. but Insulin and insulin resistance were significantly increased in control group. 3) Growth hormone was significantly increased in resistance exercise training group. 4) Insulin-like growth factor-1 was significantly increased in resistance exercise training group. It was concluded that 11 weeks of resistance exercise training would be beneficial for body composition, Insulin resistance, growth hormone and insulin-like growth factor-1 in obese college male students.
