It is a common knowledge that the motion of the head plays an important role in applying the Judo throwing techniques. It greatly influences the retention of the posture in the process of the applying the techniques, and also affects the making full use of the power which is needed in the throwing.In this study, we regard the motion of the head, the shoulders, and the hip, which affect very much the throwing, as the rotary motion against the median line; and we try to explain in what way the head, the shoulders, and the hip move and how thiw rotary motion affects the motion of the head in the throwing.The following results was obtained.1) It was observed that in the case of well-trained the body had turned round before the head began to turn at the completion of “Taisabaki” (body turning) and the motion of the head was restrained; but in the case of middle-trained and untrained, the head had turned round before the shoulders at the completion of “Taisabaki” (body turning).2) In the phase of “Kake” (attack) of well-trained, the head turned round at a time, and a angle difference could be observed between the head, the shoulders and the hip; i. e. the head had turned first, the followed the shoulders, and the hip: and this angle difference between the head and the body was smaller than the case of middletrained and untrained. Therefore we could say that the head, the shoulders, and the hip co-ordinated well in this case. But in the case of middle-trained and untrained the angle difference which was observed at the completion of “Taisabaki” (body turning)continued, and it became even larger than it was at the completion of “Taisabaki”(body turning). So in the case of middle-trained and untrained, it was observed that only the head turned round too much in the throwing.3) In the case of middle-trained and untrained, it was observed at the phase of “Kake”(attack) that the position of the hip was too high, so therefore the direction of “Hikite”(pulling hand) was not correct, and “Tsurite” (lifting hand) did not work well, so that the motion of the shoulders was restricted. The motion of the shoulders is important to the effective motion of the head. This motion of the shoulders is influenced by the correct position of the hip and the correct direction of “Hikite” (pulling hand)and the correct way of “Tsurite” (lifting hand).

The purpose of this study was to clarify the characteristics and relationship between somatotype and standing posture in Judoists and Kendoists. In this study the 245 male athletes from 15 sports events at the University of Tsukuba were classified as to their body type by the Heath Carter somatotype method. And measurement was taken of the spine curvatures, the difference of bi-acromion height, the weight distribution between right and left foot and the location of center of gravity in anterior posterior axis of foot.The results were as follows:1. The characteristics in somatotype of Judoists showed large mesomorphic and endomorphic components. The somatotype of Kendoists showed resemblance to that of Soccer and Tennis player.2. The intensified dorsal curvature was one of the characteristics in Judoists' posture. Kendoists had a tendency to be inclined backward in head and neck position.3. Judoists who showed endomorphic mesomorph type had a tendency to be inclined backward in their upper bodies. And Kendoists who showed ectomorphic mesomorph type had a tendency to shift their weight forward.
