Electromyographic Analysis of Hip Abducter Muscles during One Foot Bridging Motion

Abstract

Purpose] In this study, we compared muscle activities in one foot bridging motion with those in hip abduction motion to examine its effectiveness.[Subjects] The subjects were twelve healthy adults with a mean age of 21.2 years.[Methods] The subjects were requested to perform isometric shrinkage for hip abduction with changes of load (0%, 2%, 4%, and 6% of body weight) and range of hip abduction (0, 10, and 20) and bridging on one foot. Electromyography (EMG) of the gluteus medius, gluteus maximus, tensor fasciae latae were measured in the motor task.[Results] There was no difference in EMG between one foot bridging motion and hip abduction motion.[Conclusion] These results suggest that the one foot bridging motion is effective for muscle strengthening.
