태권도 수련과 줄넘기 운동프로그램이 비만 중학생들의 신체구성, 심폐기능과 혈중지질에 미치는 영향

Abstract

This study examined how taekwondo and a rope-skipping program influenced body composition, cardiovascular functions, and blood lipid in obese middle school girls. The results were as follows.

1. The change of body composition was significantly different in weight(p<.001) and BMI(p<.001) of the taekwondo and rop-skipping group. No significant difference was found in the control group. The result suggests that taekwondo and rop-skipping has positive effects on obese middle school girls' body composition. 2. The change of cardiovascular functions was significantly different in peak heart rate(p<.05) and peak oxygen uptake(p<.05) of the taekwondo and rop-skipping group. No significant difference was found in the control group. The result suggests that taekwondo and rop-skipping has positive effects on obese middle school girls' cardiovascular functions. 3. The change of blood lipid was significantly different in total cholesterol(p<.05), HDL cholesterol(p<.05), LDL cholesterol(p<.001), and trigylceride(p<.001) of the taekwondo and rop-skipping group. No significant difference was found in the control group. The result suggests that taekwondo and rop-skipping has positive effects on obese middle school girls' blood lipid.

Based on the results, taekwondo and rope-skipping can be a useful exercise program to improve physical fitness and reduce weight, resulting in decreased risk of cardiovascular diseases in obese middle school girls. It also can reduce blood lipid, a cardiovascular diseases index and improve obese middle school girls' health.

The government and the Ministry of Education should increase the instruction time of physical education related with physical activity in a curriculum for obese adolescents not getting enough physical activity and support the obesity prevention for adolescents actively.
