The purpose of this study is to clarify the characteristics of the standing posture of the Judomen in comparison with the Kendomen and non-athletes. The investigation of standing posture was made by taking photographs of lateral aspect applying the conformateur (Fig.2) and measurement of several angles such as shown in Fig.1 concerning the curves of the vertebral column. And also, we studied on the E. G. G. (Electro Gravitio Gram) by the gravianalyzer and the relationship between perpendicular line of tragions and C. G. line. Measurements were made in case of three kinds of standing posture, viz., usual relax posture, strained good posture and military posture.
The subjects for this study were thirty Judomen, thirty four Kendomen and twelve non-athletes, students of Tsukuba Uuiversity, aged 18-25 years.
The results were as follows:
1) Of the vertebral angles of the Judomen, the angle A (inclination of cervical lumbar line) took a positive value, but in the case of Kendomen took a negative value.
2) The C. G. line of right attitude in the Judomen took a left side position from sagittal plane while it took a little right side position in the left attitude.
3) The duplication of two lines (tragions perpendicular line and C. G. line) was not appeared in the Judomen.
4) The Shizentai (basic standing posture in Judo) showed more stable posture than the other standing postures.
