采用两台国产摄像机,以240帧/秒的频率对湖北省跳高运动后备力量刘晨阳的背越式跳高技术动作进行拍摄,并采用美国ARIEL三维图像解析系统对刘晨阳的助跑最后一步技术动作进行解析,并将获得的运动学技术参数与国内外优秀运动员的技术进行比较分析,找出该运动员在技术上存在的差距并做出诊断,为我国跳高后备人才有针对性的训练提供科学依据. Using two domestically produced cameras, shooting at the speed of 240 frames per second, Liu Chenyang, a backhunger high jump technical action of the reserve force of high jump in Hubei Province, was taken and the technical action of Liu Chenyang ’s last step was analyzed by the American ARIEL 3D image analysis system. The technical parameters of the kinematics are compared with those of the elite athletes at home and abroad to find out the technical differences of the athletes and to make a diagnosis so as to provide a scientific basis for targeted training of the high jump talents in China.
