The purpose of this study was to analyzed the physique development of elementary school children. To achieve these purpose, linear LGM(Latent Growth Modeling) ans unspectified LGM was implied. to analysis data, 208 third grade boys and 236 girls in middle schools in Seoul were selected. The repeated measures on height , weight, and MBI(body mass index) during elemenraty school were used as the outcome variables . the method for data analysis was sed LISREL(version 8.12) Results based on this procedures and data analysis are as follows; First, height and BMI of boys and girls during elementary schools were linear pattern. Secone, change rates on height indicated linear growth. And change rates on weight and BMI were incresed gradually. Third, height, weight, and BMI of boys and girls during elemenraty schools indecated that intercepts and slopes had interindividual difference, Forth, height , weight and BMI of boys gilrs during elemenraty schools indecated that intercepts and slopes had positive correlation. In suggestion to determins whether factors affect chileren\'s change in another field of physical educaiton, esperically physical fitness or sports skill, further patent growth modeling extension would be considered. Also, to assess change accurately, individuals\' change must be assessed with considering the correlates of initial status and change rate.
