링 종목 뒤 오르며 swallow 동작의 기술 분석

초록

The purpose of this study is to find out information available for minimizing a cut in marks on motion by grasping kinematical variable in upraise to swallow support(difficulty E) motion following rings. For this, as a result of carrying out the 3 dimensional motion analysis targeting 2 male elite gymnasts, the following conclusions were obtained. S1 in Ph3, which has direct influence upon evaluation given swallow motion, showed 2.117 seconds, thereby having been indicated to have no demerit mark at all caused by the rest time. On the other hand, S2 showed 0.833 seconds, thereby having been evaluated to fail to be recognized as technique(difficulty degree) along with demerit mark in 0.5 point by big mistake. S1, the length in whole-body segment was 41% in the upper direction from ring(axis), thereby having been indicated to be biased to the upper direction. On the other hand, S2 accounted for 63% in lower direction, thereby having been indicated to be biased to the lower direction a little much. Thus, it is necessary for work that sends the whole body forward by narrowing shoulder angle after enhancing muscular strength in the upper body. S2 was indicated demerit that decline rate continues to be caused, resulting in having not been stopped at all. Thus, the power in the upper body is judged to be short, which is enough to allow the body to stop with horizontal posture on the ring.
