The purpose of this study was to analyze the effect of exercise time difference of weight bearing exercise training on body composition and fitness of elementary school children. Elementary school children in grades 4-6 were participated in the 16 week weight-bearing exercise training. Subjects were divided into 3 groups, continuous exercise group exercised 3 days per week for 60 minutes a day and intermittent exercise group exercised 3 days per week three times a day for 20 minutes, control group continued daily life for 16 weeks. Physical fitness and body composition were evaluated. In the results of the study, body fat in both exercise groups was reduced than control group after 16 week training, while muscle mass was increased in both exercise groups. There were no significant differences between continuous exercise group and intermittent exercise group. For physical fitness measurements, muscular strength, agility and quickness were increased in two exercise groups. I suggest that continuous exercise and intermittent exercise of weight-bearing training are both appropriate for improvement of body composition and fitness of elementary school children.
