電磁ゴニオメータによる肩甲骨から体幹の三次元動作解析 : 健常者とパラカヌー選手の比較 Three Dimensional Motion Analysis of Upper Limb and Trunk With an Electromagnetic Tracking Device: Comparison of a Healthy Canoe Athlete and a Para Canoe Athlete by Hiroaki Kimura, Tetsuhiko Sakamitsu, Junpei Sasadai, Kazuhiko Hirata, Yukio Mikami Hiroshima University Hospital ABSTRACT Motion analysis is an important tool to accurately measure motion during sports activity. Method of motion analysis so far are mainly two-dimensional, So was insufficient. The purpose of this study is to analyze the movement of the upper limbs and trunk of canoe athletes during upper limb elevation or paddling using electromagnetic goniometer three-dimensional motion analysis equipment This time, we compared healthy canoe athlete and para canoe athlete on upper limb and trunk movement during paddling with an electromagnetic goniometer. Healthy canoe athlete showed greater upper limb elevation movement, while para canoe athlete tend to have greater scapula motion. Canoe competition requires trunk rotation movement, Vol.
para canoe athlete with may be using more scapular motion to compensate for lack of trunk rotation of. Our findings suggest that healthy canoe athlete demonstrate greater trunk motion. Therefore, scapular flexibility and control are necessary in the para canoe athlete who is hard to convey a power by kinetic chain from the trunk like healthy canoe athlete. It was suggested that para canoe athlete receiving different training than healthy canoe athlete. 要旨 諸言 Codman acromial method Konda Yanai Yanai POLHEMUS Liberty m KL KLKL KL Vol.
