| Summary: | 碩士 === 國立臺灣體育運動大學 === 體育研究所 === 104 === The purpose of this study was to investigate the kinematical characteristics in the methodology of cinematography for the elite pole vaulters at the 2015 National Taiwan High School Athletic Games. Two high definition digital video cameras (Sony HDR-FX7, 60 Hz) were used to record the movements of the gold and silver medalists. The Vicon Motus (version 9.20) two-dimensional cinematography system was used to digitize and to calculate the kinematic data for each trail of the pole vault. The results showed the speed loss, horizontal displacement of CG during the takeoff phase, vertical takeoff velocity, and the percentage of maximum shortening of pole chord were not significantly different for the gold versus silver medalists. The silver medalist was better than the gold medalist in the parameters of horizontal velocity of run-up, stride length, vertical velocity at release, takeoff angle at release, and the peak height. But the gold medalist showed the speed decrease and the torso tilt angle less than the silver medalist. This study suggested that the gold medalist should be strengthening the horizontal velocity of run-up, and the silver medalist should be strengthening the trunk posture during the phase of pole plant.
