The purpose of this study was to investigate the effects of low frequency and aerobic exercise on body weight, fat mass, percent body fat (PBF), lean body mass (LBM), body circumference, resting metabolic rate (RMR), energy intake (EI), binge-eating disorder (BED), coping strategy indicator (CSI), r...
The purpose of this study was to investigate the effects of low frequency and aerobic exercise on body weight, fat mass, percent body fat (PBF), lean body mass (LBM), body circumference, resting metabolic rate (RMR), energy intake (EI), binge-eating disorder (BED), coping strategy indicator (CSI), respiratory exchange ratio (R), oxygen uptake and energy expenditure in obese women. The subjects of this study were twenty obese women who participated in this experiment voluntarily and didn't have any disease. The subjects were divided into two groups : low frequency electrostimulation with aerobic exercise group (LFE+EX, n=11), aerobic exercise group (EX, n=9). Both of the experimental groups were trained for 8 weeks. The subjects in the aerobic exercise performed 60 min in about, three times per week at the low intensity. The low frequency electrostimulation treatment which done to LFE+EX group was accomplished to part of uper arm, back, abdomen, femur, waist, hip, calf for 30 min/day and 3 days/wk using a low frequency electric stimulator at the level of 60Hz and 200Hz. For body weight, fat mass, PBF, LBM, body circumference, RMR, BED and CSI were conducted before and after treatment. For EI was conducted before treatment, at the every weeks during treatment and after treatment. For R, oxygen uptake and energy expenditure were conducted using gas analyzer in mid treatment. Statistical techniques for data analysis were paired T-test to determine the differences among treatment and One-way ANOVA to determine the differences among groups and Duncan's multiple range test to multiple comparison in mid treatment. The 5% level of significance was utilized as the critical level for acceptance of hypotheses for the study. The following results were obtained from this study. The body weight, fat mass, PBF, 8 site body circumference, BED and EI were significantly decreased, and RMR was significantly increased in the LFE+EX group. However, the EX group was significantly decreased only on 3 site body circumference (waist, low-thigh, calf) after 8 weeks and another 3 site body circumference (chest, up-thigh, upper arm) were not altered after 8 weeks, however the levels of significance (0.0543, 0.0556, 0.0540, respectively) were closed to P=0.05 utilizing as the critical level for acceptance of hypotheses. And LBM was not altered after 8 weeks in the EX and LFE+EX group. The R was significantly decreased only on the level of 200Hz during the low frequency electrostimulation and oxygen uptake was significantly decreased both on the level of 60Hz and 200Hz during the low frequency electrostimulation. The energy expenditure was not altered on the level of 60Hz and 200Hz during the low frequency electrostimulation, but the level of significance (0.056) was closed to P=0.05 utilizing as the critical level for acceptance of hypotheses. As this results, it is suggested that low frequency electrostimulation with aerobic exercise is much more effective than only aerobic exercise in improving the body fat loss, health care and exercise capacity on the obes
