Abstract
1) 746 Fukushima youths above the senior high freshman age were measured in summer, 1967.
2) Compared with the national average, they are slightly shorter and fatter.
3) Gradual growth is observed before they reach the high school senior year in stature, chest girth, shoulder breadth, neck-base girth, thickness of subcutaneous fat of the back, and bodyweight. Thereafter the growth almost stops in the female except for chest girth and bodyweight the male shows slight growth in all items but stature which makes large increase.
4) Angles of shoulder slope are larger than those of junior high pupils. There is a significant difference between the 3rd year pupils of junior high and freshmen of senior high in both sexes. Females always have more sloping shoulders than males, but this sexual characteristic is less obvious in our subjects than in the youngers. About 82% of the males have the angles ranging from 17°to 26°, and about 80% of the females from 19° to 28°. In each sex, the angles are, unlike those of the youngers, more densely distributed in the larger value region. This is especially conspicuous with males.
5) There is very little correlation between shoulder slope and other measured items.
