The hip abductor muscles play an important role in human walking. Their weakness causes a disability in walking efficiency. However, muscle strengthening exer¬cise for hip abductors is often involved with the trick motion of pelvic elevating. The pur¬pose of this study was to discuss methods of strengthening exercise of less trick motion for hip abductors. Seven males and three females participated in this study. The subjects whose hips were abducted by the method of isometric contractions were as follows: 1) bilateral contrac-tion of hip abductors simultaneously; 2) unilateral contraction of hip abductors with the oppo¬site leg immobilized; 3) unilateral contraction of hip abductors without the opposite leg immo¬bilized. The activities of the hip abductors and the elevators of pelvis were also measured by electromyography. The results of this study were that bilateral contractions showed the large activity of the hip abductors and the small activity of elevators of pelvis rather than unilateral contraction (P <0.01). It is suggested that bilateral contractions of hip abductors are less trick motion and more effective as a strengthening exercise for hip abductors.
