|
Purpose : The study investigated the effects of Pilates exercise on strengthening trunk muscles of females who perform such exercise for the purpose of comparing activation of trunk muscles that contact while performing Pilates motions between females with and without at least 8 weeks of Pilates experience.
Method : The study investigated 10 females with at least 8 weeks of Pilates experience in the past one year (Expert group) and 10 healthy females without Pilates experience (Non-Expert group). The study used basic Pilates postures involving hip abduction, lift, and leg swing motions as the measurement postures in comparing the activation of muscles used for stabilization, such as the rectus abdominis, external oblique abdominal, and transversus abdominis & internal oblique abdominal muscles. Surface electromyography (4D-MT& EMD-11, Relive, Korea) was used for measuring muscle activation, and the measurements targeted activation of the rectus abdominis, external oblique abdominal, transversus abdominis, and internal oblique abdominal muscles.
Result : The study results showed that, as compared to the Non-Expert group, the Expert group had significantly higher muscle activation in the transversus abdominis and internal oblique abdominal muscles during hip abduction (p<.05) and significantly higher muscle activation in the rectus abdominis, external oblique abdominal, and transversus abdominis & internal oblique abdominal muscles during lift and leg swing motions (p<.05).
Conclusion : Pilates exercise performed over a long period can be recommended as an effective exercise method that can increase the activation of trunk muscle, and especially, repeated performance of highly difficult motions can increase muscle activation even more, which can help promote spinal stabilization, prevent pain, and improve performance of activities of daily living.
