on, showing rather a tendency of backward inclination. In case of the For the purpose of disclosing the morphological feature of top class judo champions, analyses of their standing postures were made with the conformateur as a part of the study to elucidate the physical aptitude for judo. The investigation of standing postures was made by taking photographs of lateral aspect applying the conformateur (Fig.1), and measurements of several angles such as shown in Fig.2 concerning the curves of the vertebral column. Measurements were made in cases of three kinds of standing postures, viz., usual standing posture, strained standing posture and standing posture with the forward bent head. The subjects were 24 men who joined the training camp of June,1975 and 25 men who joined the training camp of May,1977 and all of them were top class judo champions of this country.In case of the usual standing posture, the forward inclination of the upper part of the body as well as the whole body was generally smaller in judo men than the ordinary men, and there was noted a tendency, the lighter the body weight, the smaller the inclinati strained standing posture, the individual variations were generally small, and no difference in the mean value was found among body weight classes. Regarding the curves of the vertebral column, judo men showed rather larger anteriorly directed curves in the lumbar area, but the columns were rather erected in the cervical as well as thoracic area. Accordingly, the center of gravity was usually low in them. Even if the posteriorly directed curves in the thoracic area was stressed by bending forward the head, the above-mentioned tendency was not changed, and there was noted no difference among the body weight classes, although individual differences were noticeable (Table 1,2 and 3). On the basis of above-mentioned findings, it was presumed that the activity of the trunk muscles resisting against the gravity in order to keep the erect standing posture is a little more vigorous in judo men than in the ordinary men in case of usual standing posture.In short, it was considered that there is acting a contractive tension of the deep back muscles in the cervical, thoracic, lumbar and sacral area in keeping the standing posture. However, the results of analyses of the postures of judo men seem to suggest that differences in the intensity of the contractive tension are not attributable to the degree of training and the body weight, but they are merely individual differences.
