코어근육군 강화를 위한 무동력 승마운동기구개발에 관한 연구

Abstract

Objective : The aim of this study was to develop the non-powered horse riding device and was to evaluate the elaborate its applicability throughout static structural and transient structural analysis of the outdoor core strength exercise equipment. Method : Fifteen college students (mass: <TEX>$69.55{\pm}13.38kg$</TEX>, height: <TEX>$1.69{\pm}5.61m$</TEX>, age: <TEX>$21.42{\pm}1.83yrs$</TEX>) rode the powered horse riding device and 14 college students (mass: <TEX>$71.12{\pm}9.74kg$</TEX>, height: <TEX>$1.73{\pm}3.31m$</TEX>, age: <TEX>$22.50{\pm}1.47yrs$</TEX>) rode the non-powered horse riding device for the comparison. All motion capture data was collected at 100 Hz using six infrared cameras and the muscular activities were collected using a Delsys Trigno wireless system. The peak forward/backward lean angle, range of motion anter/posterior and vertical COM(Center of mass) movement of trunk and pelvis segment, and muscle activities of six muscles were compared between the two devices by using independent t-test (p<.05). Results : Several kinematic variables (peak forward-backward lean angle and vertical COM movement of trunk and pelvis segment, range of motion of trunk) significantly different between non-powered and powered horse riding device. The muscle activities of Rectus abdominis and External oblique of abdomen on the non-powered horse riding device were significantly greater than those of the powered device. Conclusion : It was concluded that non-power horse riding device could give the effect of core strength exercise as well as the body motion which can simulate the powered horse riding device.
