Since 1947 to June 1954 we have taken measures six times on 11 points of physical strength such as the height, the weight & the girth of the chest, etc. and athletic' function such as the grip, back muscles etc. on 52 novices or new in 1947, while 31 of them have retired from the dohyo, and 21 are left.
At the beginning because of training the weight had decreased, but after 2 years and half it began to increase. After 3 years and a half, on account of training of the body, especially the upper part of the body, grew round. The girth of the chest, waist, , , upper arm and under arm and width of the shoulder, chest and hip had grown well, .. when 3 years and a half passed, the growth was evident, eg. sumo physical proportion..
On the growth of the chest, increment of the transverse diameter was more than. that of the anteroposterior diameter which shows the similar tendency on the growth of the judo-men as reported by Mr. Shioya.
In a comparison with ordinary people, the grip is stronger than back muscles and in spite of the growh of the body, athletic function has not grown so much because of injury by hard training.
Generally speaking, among those who retired within a year many had been squat at the begining, short in height, and heavy in weight, and did not increase in height.. Among those who retired within two years and a half, many had increase in height to a certain degree but the expected increment in weight was not satisfactory.
A comparison of active and retired sumos, most of the former showed graduaL, increment in weight and most of the latter lost weight and required consideradle amount of time to recover. The formor excelled the latter in height and weight from the beginning.
To be a good sumo requires training and a mind which is able to endure thetraining, as well as inherent physical strength.
During the pennant seasons of 1948, 1949, and 1950 absorption of food of the junior grade of wrestlers without regards to the seasons were 3500-4000ca1.
