This study is aimed at reveling how physical development and stamina improvement affect growing children in exercise group(n=13) and control group(n=13) for 12 weeks. An object of study is 26 growing schoolage children that were arranged into random assignment and were sorted into two groups.(Exercise group and control group) Then they took part in Taekwondo multicomponent exercise program. Before and after experiment, we measured subjects' physical development and stamina twice. From the results, we carried out correspondence samples t-test for significant difference verification in groups and independent sample t-test between groups. Level of significance was established with p<05. Then, we come to the following conclusion

1. change of physical development Weight. of exercise group was increased and there was not significant difference statistically(p<.01, p<.001). The body fat was reduced, but fat-free mass was increased. Statistically, there was significant difference. Statistically, control group showed significant difference of increasing weight,. body fat. and fat-free mass. Because subjects taking part in experiment are growing schoolage children, height. and weight seem to be increased steadily. There is not significant difference between two groups.

2. change of stamina In exercise group, body strength factor muscle strength ,muscle endurance, cardiovascular endurance , flexibility of the body, explosive muscular strength were respectively increased. so there was significant difference statistically. In control group, body strength factor didn't show significant difference statistically. after experiment, muscle endurance, cardiovascular endurance showed significant difference between groups statistically. As a result of this study, growing children taking part in a 12-weeks Taekwondo multicomponent exercise program got positive effects of increasing physical development and body strength factor(muscle strength, muscle endurance ,cardiovascular endurance, flexibility of the body, explosive muscular strength) in exercise group. In the next study, it is suggested that not only a little further methodical and scientific exercise program but also studies made up of all age groups be planned. Also, it is important to set up a specific study plan and discuss the study in depth.
