Abstract

In the present study, annual change of physical growth and development was examined during school age. Based on the records of the physique (height, weight, sitting height, leg length), physical strength and motor ability (grip strength, side step, trunk bending, sit-up, 50m dash, standing long jump and handball throwing) announced by Ministry of Education, Science and Technology every year, the wave let interpolation method was applied to cross-sectional data from 6 to 17 years in 2000 and 2005. As the results, the growth distance and velocity curves were analyzed in the physique. In physical strength and motor ability, the developmental distance and velocity curves were also analyzed, and the change of physical strength and motor ability with age was examined. With judging from the growth velocity curve of physique, the growth velocities in leg length was the fastest among the physique in both 2000 and 2005. Moreover, the age at MPV of leg length was also the earliest, and that of sitting height was the latest in 2000. It was shown that MPV of physical strength and motor ability appeared after MPV of height.
