댄스스포츠가 비만중년여성의 건강관련체력과 CRP, Leptin, TNF-α, Adiponectin 농도 변화에 미치는 영향

Abstract

This study was intended to examine the effects of a 12-week dance sport program on the changes of health-related physical fitness and CRP, leptin, TNF-α, and adiponectin concentration in 20 obese middle-aged women with >30% body fat. Finally the following results were obtained.

1)As for the body composition factors of health-related physical fitness, the dance sport group showed a statistically significant difference in weight and % body fat at p<.001, LBM at p<.05, and WHR at p<.01. As for health-related physical fitness factors, there was a statistically significant difference in muscle strength at p<.01 and muscle endurance, flexibility, and cardiorespiratory endurance at <.001. There was no significant difference in the control group as a result of pre- and post-test. It was found that the dance sport program was effective for improving health-related physical fitness in obese middle-aged women. Based on this result, dance sport can be an effective obesity management program as a low-intensity aerobic exercise program in obese middle-aged women.

2)As for the change of CRP in the dance sport group, there was a statistically significant difference at p<.05. However, the control group showed no significant difference as a result of pre- and post-test. This result suggests that weight loss by continuous exercise can decrease CRP concentration.

3)As for the change of leptin in the dance sport group, there was a statistically significant difference at p<.05. However, the control group showed no significant difference as a result of pre- and post-test. Leptin is known to increase food intake, decrease heat generation, and control appetite, weight, and energy consumption by working on hypothalamus. This result suggests that the dance sport program had a positive effect on the decrease in leptin.

4)As for the change of TNF-α in the dance sport group, there was a little decrease but no statistically significant difference. The control group showed no significant difference as a result of pre- and post-test. TNF-α, which is a kind of cytokine, is known to induce vascular inflammation. Although a statistically significant difference was not found, it was found that weight loss by the participation in the dance sport program led to the decrease in TNF-α concentration.

5)As for the change of adiponectin concentration in the dance sport group, there was a statistically significant difference at p<.05. However, the control group showed no significant difference in the results of pre- and post-test. Cardiovascular mortality is known to be related to chronic renal failure patients with high serum adiponectin level and obesity. As shown in this result, if obese people achieve effective weight loss by applying the dance sport program, adiponectin level highly connected with cardiovascular diseases can be decreased.

In conclusion, the dance sport program was found to reduce the risk of metabolic syndrome through decreasing weight, % body fat, and WHR and be effective in decrease in CRP, leptin, and serum adiponectin concentration in obese middle-aged women. Furthermore, it was effective enough that all participants in the dance sport group were satisfied with their weight management. Thus, it suggests that participation in the dance sport program may have a positive effect on obesity management and improvement in quality of life in obese middle-aged women.
