The purposes of this study was to identify the effects of regular training on body composition, bone mineral density and growth factors by taekwondo training program in the children. Subjects were aged 11~13 years. There was classified two groups (experiment group 12, control group 12), total 24. Measured items for this study were body composition (weight, percent body fat, body mass index), lumbar (L2, L3, L4), femur (neck, trochanter, ward’s triangles) bone mineral density and growth factors (growth hormone, IGF-Ⅰ, IGFBP-Ⅲ) in the 12weeks before and after. Results of this study were as follows; In the body composition, there were showed significant differences on the weight, percent body fat and body mass index level between groups. In the bone mineral density, there were showed significant differences on the lumbar 2, 3, and femur neck, femur trochanter, femur ward’s triangles level between groups. In the growth factors, there were showed significant differences on the growth hormone, IGF-Ⅰ, and IGFBP-Ⅲ level between groups. This study showed that an 12weeks taekwondo training program affected in a positive effects in almost of items in trained children.
