체조 도마 종목 Yeo 2 동작의 결정요인 비교 분석 = Comparative Analysis of Determinant Factor of Yeo2 Motion in Vault

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the technical factors of Yeo2 motion though video analysis and evaluate the its possibility as a new technology. The subject in this study was 3 male gymnastic players of the national team who can perform Yeo2 motion. As a result, the conclusions were as follow; In the time spent for each phase, KSM should reduce the pre-flight phase time. YHS and KHH should shorten the horse contact time. In the horizontal shift of center of mass(CM), KHH translated to the anterior side slightly but KSM showed a posture that the CM translated to the forward a lot. YHS showed the ideal posture by shortening the anterior movement at the pre-flight phase. During the board landing, KHH took the low posture. In the horizontal velocity of CM, KHH was slow and KSM didn`t convert horizontal movement to vertical. In case of horse contact and take off, the players should keep the hip and knee angle. Also, in the vault take-off, they have to take the body motion at the vertical state. It is recommended that the body rotation angle and twist angle should keep large angle in the pre-flight phase and rotation in the air. Moreover when the angles reached the peak, they should take the vertical motion. Finally, they should increase the body rotation angular velocity at the pre-flight and post-flight phase, control the speed in the board and horse contact period, and increase the body twist angular velocity to the peak value.
