The objective of this study was to investigate the change of the physical characteristics according to the grade progress, measuring the physique, % body fat, physical fitness and kinetic ability in the 1 to 4 grades of the navel female cadets. In result of the study, the change which follows in the grade progress of the physique and % body fat did not appear significantly, but the change in the physical item was showed the improved tendency. Especially, the sargent jump, grip strength followed in the grade progress appeared significant. And the side step, sit and reach, push up, sit up, and VO<sub>2max</sub> was showed the rapid increased tendency comparing with the entrance time in the academy. In the order to verify about the physical strength according to the accumulation of the % body fat by the regression polynomial, the physical strength level according to the degree of the obesity did not the difference and this study did not appear that the standard body type was higher than the slim and obesity body type in the physical strength level.

The studies on changes over time in the physique have also been conducted from cross-sectional data in Korea, although the history is not as long. However, since cross-sectional data are used in these studies the earlier maturation of children cannot be verified even if it is shown that they are becoming larger. To verify an accelerated growth phenomenon, analysis of longitudinal data is essential. In this study we used past and present longitudinal growth data for height and weight of Korean girls. A wavelet interpolation model was applied to verify annual trends in physique, and the accelerated growth phenomenon in Korea was examined. The subjects were 433 girls in the final year of high school in 1995 and 304 girls in the final year of high school in 2007. The wavelet interpolation method was applied to longitudinal growth data for height and weight of these boys from the first year of elementary school until the final year of high school. The results showed that the 2007 girls were distinctly larger than the 1995 girls, and earlier growth was also confirmed. In addition, the number of mid-growth spurts was not changed between past and present, it might be difficult for appearance pattern of mid-growth spurt to judge because physical maturation rate in girls is earlier than in boys.
