The purpose of this study was to investigate the effect of Taekwondo and calcium intake on physique, growth hormone and IGF-1 in elementary school male students. 24 subjects who the fourth grade and Taekwondo black belt (1～2 poom) were classified into three groups; Taekwondo +calcium intake group (8), Taekwondo group (8) and control group (8). The period of Taekwondo was 12 weeks, 5 times a week and each time 50 minutes with RPE (7～15) for intensity were treated and subjects were given calcium at 750 ㎎ of pill after dinner a day during the 12 weeks. The conclusions of this study are as follows; In the comparison within each group, three groups all significantly increased in body height but in the comparison between groups, A and B groups were more significantly increased in body height than C. C significantly decreased in growth hormone and in the comparison between groups, A and B groups were more significantly increased in growth hormone than C. In the comparison within each group, A and B significantly increased in IGF-1 and in the comparison between groups, A and B groups were more significantly increased in IGF-1 than C. It is considered that Taekwondo and calcium intake give effects to body height by increasing growth hormone and IGF-1. It is necessary to continue the study, because the study results of growth hormone and IGF-1 are various by training method, intensity, nutrition.
