Abstract:
The purpose of this study was comparing the effect of 6-week yoga training program in healthy women between 30-45 years old. Each 39 females were categorized into training and control group. Before and after 6 week, participants were measured postural sway during double and single leg stance while eyes opened and closed by using force plate, lumbopelvic stability during single-leg landing, measured muscles activities by surface EMG and measured back muscle power by using isokinetic dynamometer. The result found that balance in single-leg stand in yoga group were significant greater than control group (p<0.05). Lumbopelvic stability analyzed by angular displacement and angular velocity. There were no significant difference between groups for angular displacement and angular excursion. The angular velocity showed significant differences between groups for mean velocity lateral bend (p<0.05). EMG activity of gluteus medius muscles in yoga group was decrease than control, but there was no statistically significant differences. The group of back muscles power in yoga group was increase than control group, but there was no statistically significant differences. Therefore 6-week yoga training program can improve balance, back muscles power and lumbopelvic stability might to decrease risk for low back pain in women.
