Studies on the Physical Surface Area of Japanese

Surface area of 201 Japanese (both sexes) from infancy to old age selected statistically according to sex, age and body shape were measured and the regional rates calculated and discussed.The results are as follows:1. There was no difference between either side of the body for any age or sex.2. The rate of head, face and neck decreased while that of the lower extremities increased with aging.3. After adolescence regional rates could be differentiated between the sexes. The rates of the thigh of the female were considerably higher than that of the male.4. Body shape, rate of the head, face and neck the tendency waslowest toward obesity and highest toward slenderness. The rates of the limbs, upper and lower extremities revealed the opposite tendency to the former.5. These results vary little as compared to other studies done on Japanese. However, compared to a German oran American revealed a higher rate for limbs. The rate was definitely lower for the Westerner.6. Judging statistically the sublects and methods in this study, the regional rates of body surface described in this paper according to sex, age and body shape are acceptable to be used asastandand for the Japanese people for the study and review of all physical parts.
