승마 운동이 sit-to-stand 동작 시 신체 동적 안정성에 미치는 영향

Abstract

The purpose of this study was to analyze the effect of horseback riding exercise on the body dynamic stability of body during STS(sit-to-stand) movement. Twenty teenage students participated in this study, and 8 motion capture cameras were used during STS before and after the 12-week horseback riding exercise program. The knee, pelvis, and trunk segment root mean square acceleration and attenuation factors were analyzed in the AP, ML, VT directions. paired t-test was evaluated to compare mean differences between before and after 12 weeks. During sit-to-stand motion after horseback riding exercise, the ML direction RMS acceleration value of the trunk segment decreased, whereas the pelvis and trunk segment RMS acceleration values increased in the AP and VT directions. And while the VT direction Ckp and Ckt attenuation values increased, the VT direction Cpt and ML and AP direction attenuation values decreased. Therefore, it was found that horseback riding exercise also affected the attenuation determined by the forward and upward body acceleration of teenagers and the mutual acceleration of body segments during STS.
