Abstract: ブリッジ動作訓練において,より効率の良い肢位を検討するために,股関節外転角度の違いが股関節周囲筋の筋活動に及ぼす影響について調査した.対象は健常男性14名とし,大殿筋・中殿筋・大腿筋膜張筋の筋活動について表面筋電計を用いて導出した.ブリッジ動作の肢位は足部を揃えた位置(閉脚位),股関節外転0度(中間位),股関節外転20度(開脚位)で行った.その結果,股関節外転20度では中殿筋・大腿筋膜張筋の筋活動量は有意に増加し,変化率では中殿筋が最も大きかった.これらの結果から,ブリッジ動作訓練において股関節を外転させることにより, 股関節周囲筋,特に中殿筋の筋活動が最も増加することがわかった. / In this study, to evaluate a more effective posture for bridging, we examined the effects of muscles around the hip joint on the muscular activities caused by different abducent angles of the hip joint. The subjects were 14 healthy males, and the activities of, the gluteus maximus muscles, gluteus medius muscles, and tensor muscles of fascia latae were measured by rectified filtered electromyography. The measurement was performed in the bridging posture with the leg put closely (closed leg position) and at abducent angles of the hip joint of 0 degree (intermediate position) and 20 degrees (astride position). The activities of the gluteus medius muscles and tensor muscles of fascia latae were significantly high at an abducent angles of the hip joint of 20 degrees. The percent change was highest with the gluteus medius muscles. These results indicated that abduction of the hip joint during the bridging period improved the muscular activities around it, and in particular, increased the activities of gluteus medius muscles.
