5.Report Growth of the Legs

Abstract

The author studied on the growth of the legs in school boys and girls at the most secluded places of Iwate Prefecture. The results were contrasted with urban boys and girls and the following conclusions were obtained. 1. Both stature and leg length in secluded subjects were short compared with urban ones. The difference of stature between the two was mostly derived from the defference of leg length. 2. On the contrary, width of the femur and length of the inner condylus of the tibia were greater in the secluded subjects, which suggests some obstructions in the develop ment of the long bone at the lower extremities. 3. Excessive flatfoot was more frequently found in secluded subjects. This evidence was presumedly due to the way of rural life including heavy physical work and long distance walk to school.
