説明

In order to examine the somatotypes of the human flank, in May in 1974,we measured the three-hundred healthy bodies of the boys and girls of 'I' City Junior High School in Kagoshima ranging in age from 13 to 15 by means of the Type II silhouetter, The results of the examination are as follows : (This paper is continued from the preceding one and the way we took of measuring and the number of the items of the results are the same as in the preceding paper.) 1. The order of the average degree of the angles of the 13 and 15-year-old boys is : (1) posterior waist angle, (2) bust angle, (3) hip angle. But in the case of the 14-year-old boys and the 13 to 15-year-old girls, the order is : (1) bust angle, (2) posterior waist angle, (3) hip angle. In the case of the girls, they all without distinction of age show great difference in the degree of each angle, but the 14 and 15-year-old boys show nearly similar bust angle and posterior waist angle. 2. In regard to the side-silhouettes from the waist up, the girls, on the average, show greater convexity than the boys. And in regard to the average degree of the 14 and 15-year-old pupils' bust angle, and in regard to that of the 15-year-old pupils' hip angle, the girls show higher degree-than the boys with one percent of level of significance. 3. In regard to the posterior waist angle, the boys show greater convexity than the girls with one percent of significance. And the 13-year-old pupils of both sexes show the highest average degree and the degree of the angle becomes lower as they grow older. 4. In the case of the girls, they all seem to show the beginning of the womanly growth of the bust, when they reach the age of thirteen.
