The purpose of this study was to analyze the variation of body shape and to divide growth period into some age groups based on body type. Duncan Test, Heath-Carter's somatotyping method and allometry equation (y=bx^α were applied to somatometric data concerning obesity/leanness. The materials were 309 females aged from 12 to 17 years old.
The following results were obtained:
1. In the Developmental trend of the human body, the 12-13 age groups belonged to the accleration stage of adolescent growth spurt. The 14-15 age groups belonged to the latter period of adolescent growth. The 16-17 age groups belonged to the termination stage of adolescent growth.
2. In the Heath-Carter's somatotyping method, the average somatotype changed into M-MC-CM-D with age.
3. In the allometrical analysis, the first critical point appeared at the stature 146 Cm in case of weight, LBM and fat. The second critical point appeared at the stature 154-157 Cm in case of LBM and Fat. All the three measurement showed positive allometry.
