Abstract
|
|
|
Objective: The purpose of this study was to investigate the maximum voluntary isometric(MVIC) of gluteus medius muscle determine if there are differences in these MVIC with respect to different position.
Method: 30 healthy subjects with no known musculoskeletal disorders were recruited as the participants.
The MVIC hip abduction at nine different position. Differences in MVIC in according with various condition were assessed by use of repeated one-way ANOVA. Differences surface and muscle contraction type were assessed by use of paired t-test.
Results: Glureus medius muscle MVIC were significantly greater for hip abduction at angles of 0° and 25°than 45°, were significantly greater for ankle than knee area, and were significantly greater for eccentric contraction than concentric contraction.
Conclusion: Hip abduction at angle of 0°and 25°, ankle, and eccentric contraction position may be effective in activating the gluteus medius muscle.
