Abstract
The purpose of this study was to investigate the effect of bone age on physique and physical fitness in elementary school students. For this purpose, the structural equation model test was conducted based on the three-year longitudinal study. The results were as follows. First, bone age in boys and girls (1st~3rd grade) has a direct effect on the change of body size, but it does not affect the change of physical strength. Second, the bone age of the senior male students(4~6 grade) gave a direct effect on the change of physique, 50m running, and sit-up. On the other hand, it gave an indirect effect on push-ups, sitting basketball throws, and standing long jump. Third, the bone age of the female students(grades 4~6) affected directly on body size change, sit-up, side step and indirect effect on 50m running, half squat jump, and standing long jump. These results indicated that the evaluation of the bone age of the subjects should be included in the exercise ability evaluation items for the male and female students in elementary school over the fourth grade in relation to the myofunction.
