레슬링 가슴 잡아 골반 측면 들기 동작의 운동학적 분석 = Kinematic analysis of pelvis side lifting technique after grabbing chest for Greco-Roman style wrestling

다국어 초록 (Multilingual Abstract)

This study is to examine the peculiarity from kinetic analysis on pelvis side lifting technique after grabbing chest for wrestling. Moreover, the purpose of this study is to grope for smoother movement and followings are the results. 1. Using elastic force is effective for P1 and P2 position when grabbing pelvis and at P3 position center of mass must be balanced for throwing down. Then at P4 position, the movement must be faster and quicker. 2. Center of mass is tilting to left hand side after grabbing chest to pelvis, and center of mass must tilt to left hand side step by step while throwing down the defender. 3. Center of mass must be stable while lowering and center of mass to forward then balancing out lower body to do right technique then center of mass will eventually end up forwarding. 4. Center of mass should be in lower part and should get close to defender before starting the technique and center of mass must go upper in steps of throwing down the defender. However, center of mass can not be in lower part while throwing down. 5. Velocity of left and right hand side for center of mass must be quick to move center of mass to left hand side and right before throwing down, velocity of left and right hand side be extended. 6. When grabbing pelvis, velocity of back side must be fast like snatching something, then rotate fastly to right side, however, the velocity must be stable and suitable for different kind of situations or else the defender could be able to counterattack. 7. Velocity for lower and upper part must increase to measure out the power equally and right before throwing down the defender the velocity must be slower then must check the right time and bring up the velocity level. 8. Knee angular must be in state of extension when lifting the defender and when throwing down the defender, knee angular must stay within 120 degree while using the most strength. Angular for trunk must not be horizontal to the surface.
