Morphological measurement was carried out on 43 representatives of Sumo-wrestlers, with the object of throwing light on their body build which is the largest size amoung all Japanese.
The most superior measurement was found in the skinfold-thickness amounting four times the normal value, followed by+70% in the body weight and +50-+20% in the circumferances of trunk and limbs. But superiority of the skeletal growth shown in the stature, limbslength and -breadth is much less, as little as +4-+8%.
Although their body size had been pretty larger than the average Japanese already when they entered their Sumo-school, there are enough evidences that the daily life at Sumo-school has accelerated their growth up to the abnormal level.
They spend their daily life in such conditions as that they bring all their strength into play only half an hour before the breakfast early in the morning without any physical effort in other time, and take a lot of meal generally containing much fish meat, Tofu (soybean curd) and vegetables “up to mouth”, taking no cake between meals and no smoke at all.
