장대 높이뛰기의 이지 후 공중자세 동작분석 = The analysis of swing-up motion after take-off in pole vault

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the total times, CM height and velocity, pole chord length and angle, whole body angular velocity, and stride length of pole vault. The pole vaults of four male elite vaulters including current national player were filmed using two video digital cameras at 60 Hz, and data were collected through the DLT method of three dimensional cinematography.
In general, All vaulter need to reduce last stride and a low CM during the foot support, and need to increase horizontal velocity at take-off, maintain high grip, and well timed angular momentum. MI vaulters except one need to position the take-off foot below top of the grips, to position the hips early parallel to the bar at the time of pole release, and to push the pole more downward.
