태권체조 프로그램이 과체중 여중생의 신체구성, 혈중지질과 성장호르몬에 미치는 영향

Abstract

This study examined the effects of a taekwon aerobics program on body composition, blood lipid, and growth hormone in obese middle school girls with more than 30% body fat. The results were as follows.

1. For the changes in body composition, the exercise group showed a significant difference in weight and percent body fat at the level of p<.001. The result suggested that a taekwon aerobics program reduced weight and percent body fat and had a positive effect in obese middle school girls. The control group did not show a significant difference.

2. For the changes in blood lipid, the exercise group showed a significant difference in total cholesterol(p<.05), TG(p<.001), HDL-cholesterol(p<.05), and LDL-cholesterol(p<.01). The result suggested that a taekwon aerobics program showed a significant difference in blood lipid and had a positive effect in obese middle school girls. The control group did not show a significant difference. 3. For the changes in growth hormone, the exercise group showed a significant difference at the level of p<.001. The result suggested that a taekwon aerobics program had a positive effect on the increase of growth hormone in blood lipid in middle school girls. The control group did not show a significant difference.

Taken together, a regular taekwon aerobics program is effective to reduce obese middle school girls' weight and percent body fat to prevent metabolic syndrome. It is also helpful to reduce the risk of cardiovascular diseases and prevent adolescent obesity and life-style related diseases by significantly decreasing blood lipid, and has a positive effect on adolescent growth and development by increasing growth hormone helpful for adolescent growth. It is necessary to develop various exercise programs to help adolescent growth and development.
