Comparison of Gluteus Medius Activity According to Hip Abduction Exercise Posture Using a Sling in Young Adults

다국어 초록 (Multilingual Abstract)

Purpose: This study compared the gluteus medius activity according to the posture of hip abduction exercises.
Methods: Twenty-four healthy individuals (14 males, 10 females) participated and performed exercise under three conditions: 1) side bridge exercise, 2) open kinetic chain exercise, and 3) side-lying hip abduction exercise. Surface electromyography (sEMG) was used to measure the electrical activities of the middle and posterior fiber of the gluteus medius. An independent t-test was used to assess the activity between the middle and posterior fiber of the gluteus medius for each group according to the posture of hip abduction. One-way ANOVA was used to assess the middle fiber and posterior fiber activity between the groups, and the significance level (α) was 0.05.
Results: The results revealed a significant difference in each gluteus medius fiber on the open kinetic chain (p<0.05). A significant muscle activity difference in each posture of exercise was observed in the middle fiber (p<0.01) and posterior fiber (p<0.05).
Conclusion: This study suggests that side-lying hip abduction (SHA) can help strengthen the hip abductor effectively by showing a difference in gluteus medius activity according to the posture of hip abduction exercises.
