평균대 오르기 동작시 도약단게의 반력 연구

The purpose of this study was to estimate a influence of kinetics and kinematics in biomechanical factors. Four women national gymnasts were participated as subjects of this study. It was calculated a kinetic factors using force plate form and reaction force equipment. The results and conclusion of this paper is obtained as follows ; 1. Ground reaction force of both hand was 0.58 B.W in mean maximal horizontal reaction force, 2.60 BW in maximal vertical reaction force, and 0.14 B.W in maximal left and right reaction force. 2. Reaction force during board touch was display a 2.50 B.W in mean maximal horizontal reaction force, 9.92 B.W in maximal vertical reaction force, and 1.90 B.W in left and right reaction force. 3. In the ground reaction force of both hand, a horizontal and vertical reaction forces were shown a performing in initial phase of round off, wheareas, board of reaction force aspects displayed a performing as using a horizontal reaction force in take-off before respectively after board touch. As above results, It was suggest that the study on the different motion type such as round-off at end of beam-salto backward stretched to cross stand on beam is request in future research. Also, It will be respect a injury prevention and performance improvement through a calculation of moment value of each joint during round-off and board touch.
