마루운동의 힘 물구나무서기 동작에 대한 운동학적 분석 = The Kinematical Analysis of the Press Handstand on the Floor Exercise

다국어 초록 (Multilingual Abstract)

This study was to analysis of the Press Handstand on the floor exercise and to suggest a better coaching method by knowing the mechanical variables. To the purpose, four subjects were participated in this experiment. Data was collected by Pseudo 3D. The mechanical variables of the body and joint were calculated through the temporal synchronization of the film data. As a result, the following findings were obtained:
1. In the Press Handstand motion on the floor exercise, the execution time of the Phase(start position～hip joint max flexion) was shorter than that Phase 2(hip joint max flexion～finish). The ratio was 27% vs 73%.
2. It was found that the joint angle pattern of the wrist was decreased in the Phasel and increased in the Phase2, and the joint angle pattern of the shoulder was continuously increased in the whole Phase, and the joint angle pattern of the hip was decreased in the Phasel and increased in the Phase2. The degree of the joint angles was increased in later Phase of the Press Handstand motion but the velocity of the joint angular was closed to the zero.
3. It was found that the center of gravity(CM) is continuously elevated and remained very close to the vertical line in the Press Handstand motion. And the trajectory pattern of CM was a letter 'S'.
