Advisor : Prof. Major in Physical Education Graduate School of Education, Chosun University

This study examined the effects of a taekwondo training program after school on physical fitness and blood components in obese middle school girls. The results were as follows.

1. For the changes in physical fitness, the taekwondo training group showed a significant difference in weight(p<.001), percent body fat(p<.001), muscle strength(p<.001), muscle endurance(p<.001), flexibility(p<.001), and cardiovascular endurance(p<.001). The control group had no a significant difference. The results demonstrated that the taekwondo training program had a positive effect on obese middle school girls' physical fitness.

2. For the changes in blood components, the taekwondo training group showed a significant difference in total cholesterol(p<.05), HDL-cholesterol(p<.05), and LDL-cholesterol(p<.001). TG was also effectively decreased but there was no statistically significant difference. The control group had no a significant difference. The results demonstrated that the taekwondo training program had a positive effect on obese middle school girls' blood components.

Taken together, the taekwondo training program after school can be a useful program to improve physical fitness and lose weight in obese middle school girls, resulting in reducing the risk of cardiovascular diseases. Furthermore, it reduced blood lipid which is an index of cardiovascular diseases and was helpful to improve obese middle school girls' health. Further researches should be conducted to develop various exercise programs for obese middle school girls with poor physical activity to do exercise regularly during their school days.
