Abstract

Purpose : The purpose of this study was to compare the effects of different supporting surfaces on trunk muscle activities during core stabilization exercises. Methods : A total of 20 healthy college students participated in this study for 6 weeks. In this study, we divided participants into a stable surface exercise group and an unstable surface exercise group. Each group performed core stabilization exercises of Curl-ups, Bridges, and Quadrupedal position. Core stabilization exercises were performed 3 times a week for 30 minutes during 6 weeks. The stable surface exercise group used a yoga mat while the unstable surface exercise group used AERO step. This study was designed using pre-test and post-test measurements. We used Surface Electromyograpy (sEMG) to measure for the rectus abdominis, external abdominal oblique, and multifidus muscle of trunk muscle activities. Data was processed using a paired sample t-test on SPSS 18.0. Results : For the stable surface exercise group there was a meaningful improvement in left rectus abdominis, left external abdominal oblique, and right multifidus (p<0.05). For the unstable surface exercise group, a meaningful improvement was seen in the left external abdominal oblique and right multifidus. Conclusion : From the experiment, we concluded that differences in surface can make various degrees of improvement in muscles activities, which suggests patients can choose a better option under their own conditions when planning to have a core stability exercise.
