초록

Purpose: The purpose of this study is to investigate the effect of eight weeks of regular aerobic exercise on body composition and resting metabolic rate in obese women in their 20’s & 30’s and obese women in their 50’s & 60’s who have entered menopause.
Method: In this study, the tested subjects were obese women residing in the city of S with a BMI of 25 or higher, or a body fat percentage of 32% or higher. They were separated into two age groups: women in their 20’s and 30’s (E1), and women in their 50’s and 60’s (E2). 16 subjects were selected with 8 subjects in exercise group 1 (E1) and 8 subjects in exercise group 2 (E2). The 8-week aerobic training consisted of moderate-intensity exercise at 55-65% THR. Exercise during weeks 1-4 were performed at 55-60% intensity, and weeks 5-8 were performed at 60-65% intensity. Descriptive statistics (Mean ± Standard Error) of all dependent variables were calculated using SPSS/PC+Ver. 21.0K program and the corresponding sample t-test were conducted to determine the differences in RMR, body composition, maximal oxygen uptake, and lipid profile before & after aerobic exercise. The statistical significance level was set as α=.05.
Results: There were significant differences in weight and BMI before & after training in the E1 group and E2 group before & after training (p<.001). There were significant differences in body fat percentage and total fat before & after training (p<.01) in both E1 and E2 groups. There were significant differences in maximal oxygen uptake for the E1 group (p<.01) and the E2 group (p<.001) before & after training, but only the E2 group resulted in significant differences in resting metabolic rate (p<0.01). Examining changes in TC, significant differences were found before & after training in both the E1 group (p<.01) and the E2 group (p<.05). No significant differences in levels of TG, LDL-C, and HDL-C were observed in either group.
Conclusion: Eight weeks of regular aerobic exercise result in positively improved treatment of obesity in both age groups. Both groups show decreases in body weight, BMI, body fat percentage, lean mass, and TC, as well as increases in resting metabolism rates and maximal oxygen uptake. It is observed that 8 weeks of aerobic training resulted in a variety of positive physiological changes in women with obesity.
