The purpose of this study was to examine the effect of taekwondo training after 12 weeks on abdominal fat, kidney function and inflammatory factors, CRP and IL-6, in abominal obese elderly women. We recruited subjects that the ratio of visceral fat and subcutaneous fat is more than 0.4 and GRF is less than 60 ml/min/1.73m2 in elderly women. Total 20 participants were randomly divided into a taekwondo training group(n=10), control group(n=10). The abdominal obese elderly women did the taekwondo training four times a week during 12 weeks. Body weight(p<.05), BMI(p<.05), body fat(p<.01), %fat(p<.01), SBP(p<.01) and DBP(p<.05) were significantly decreased and VO2max(p<.05) or VO2max per weight(p<.01) were significantly increased in the taekwondo training group. In regard to abdominal fat, all the factors(p<.0`) for significantly decrease in taekwondo training group. Glucose(p<.01), insulin(p<.05), HOMA-IR(p<.01), cystatin C(p<.01) and CRP(p<.01) were significantly reduced in the taekwondo training group and glucose(p<.05), cystatin C(p<.05) and CRP(p<.05) significantly increased and GRF(p<.05) was significantly decreased in the control group. Therefore, Taekwondo training positive effected on kidney function factors by decreasing abdominal fat and insulin resistance in abdominal obese elderly women. This study results indicated that regular taekwondo training may reduce and percent the death rate caused by kidney disease and inflammatory factors in elderly women and may improve their quality of life.

The purpose of this study was to investigate the effect of muscular resistance training on abdominal fat and insulin concentration. Subjects were composed of eighteen obese middle-aged women. Muscularl resistance training was performed 60minutes per day, 5 days per week at 60% of 1RM during 1∼12 weeks and at 70% of 1RM during 13∼24 weeks. The items for abdominal fat volume were measured subcutaneous fat volume(SFV), visceral fat volume(VFV), VFV/SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 24 weeks muscular resistance training. The 0.05 level of significance was as critical level for the study. The results of this study are as follow; 1. Weight(kg) was significantly decreased and %lean body mass(%) was significantly increased after 24 weeks muscular resistance training. 2. VFV, SFV and VFV/SFV were significantly decreased after 24 weeks muscular resistance training. 3. Glucose and insulin concentration were significantly decreased after 24 weeks muscular resistance training. In conclusion, total abdominal fat, subcutaneous fat, visceral fat, VFV/SFV and insulin concentration were decreased in muscular resistance training. So it could be thought that long-term muscular resistance training improve body composition and insulin concentration for obesity treatment.

The purpose of this study was to investigate the effects of Taekwondo training for 12 weeks on adiponectin, which was reported as closely related to body composition, physical fitness, insulin resistance and hyperglycemia in obese children. The subjects were 8~12-year-old obese children(n=24) whose BFP(body fat percentage) was over 25% and were randomly assigned to the control group(n=12) and the taekwondo training group(n=12). As to the Taekwondo program, the average exercise intensity was 55~60% of HRmax(maximal heart rate) during the first to fourth weeks and 65~70% of HRmax during the 5 to 12 weeks, 60minutes per each time and three times a week for 12weeks. Body composition was measured by height, weight, BFP and LBM(leanbodymass), while physical fitness was measured by grip strength, back muscle strength and sit-up. Bloods were analyzed by adiponectin, serum lipid and insulin. As a results, a significant difference was shown with regard to BFP(p<.001) after the 12 weeks of Taekwondo training, a significant interaction was shown with regard to physical fitness in such factors as forward bending(p<.05), standing on one foot(p<0.5), 50m running(p<.01), standing long jump(p<.05), side step(p<.01), VO2max(p<.01), VO2max per unit weight(p<.001). In addition, adiponectin(p<.05), glucose(P<.05), total cholesterol(p<.001), LDL cholesterol(P<.05), insulin(P<.05) and insulin resistance(P<.02) showed a significant difference in the interaction between the taekwondo training group and the other group. Therefore, it turned out that for obese children, taekwondo training not only improves body composition and physical fitness but also has a positive influences on the improvement of adiponectin and insulin resistance.

We investigated the effect of the regular combined exercise training for the body composition, serum lipid, metabolic syndrome factor and carotid artery and brachial artery luminal diameter in 50 years men in metabolic syndrome. The combined exercise training included resistance training(65%RM for first 6 weeks 15 frequency 75%RM for another 6 weeks 15 frequency) and aerobic exercise (50%HRR for first 6 weeks and 70%HRR for another 6weeks). The results showed that %body fat, total cholesterol and LDL-C were significantly decreased and lean body mass and apolipoprotein A-I were significantly increase in combined training group but body weight, BMI, WHR, insulin and HOMA-IR did not change. Waist circumference, triglyceride, fasting glucose, systolic and diastolic blood pressure were significantly decreased and high density lipoprotein cholesterol was significantly increased in combined training group. Also, carotid artery luminal diameter and brachial artery luminal diameter were significantly increased in combined training group but carotid artery intima-media and radial artery luminal dimeter did not change. In conclusion, we could find that the combined exercise training could improve the body composition, serum lipid, lipoprotein and metabolic syndrome factor in combined exercise training group. So, regular combined exercise training could positive change of carotid artery through increase carotid artery luminal diameter and brachial artery luminal diameter.
