Abstract

[Purpose] To clarify the laterality of gluteus medius muscle activity during hip abduction. [Subjects and Methods] Eleven healthy males were studied. The hip abduction strength and activity of the gluteus medius were measured. [Results] The dominant leg showed a significantly greater hip abduction torque than the non-dominant leg. Also, the gluteus medius activity of the dominant leg showed higher values than the non-dominant leg only at the mean frequency, an index of fast-twitch fiber activity. [Conclusion] The laterality of gluteus medius activity during hip abduction is likely to be closely associated with differences in the activity amounts of fast-twitch fibers. <br>
