运用文献资料、访谈和影片拍摄等方法,对三级跳远运动员曹硕的三跳技术进行分析。研究结果表明,曹硕的技术类型为单足跳型,与世界优秀三级跳远选手相比,曹硕在三次跳跃过程中起跳脚着地的角度较大。在完整技术中,曹硕具备较好的支撑和蹬伸能力,空中姿态较为合理。但在第二跳中,起跳腿的发力较为仓促,鞭打幅度需要进一步加强。与第一跳和第三跳相比,曹硕第二跳过程中摆动腿的摆动速度下降明显,应重点提高第二跳过程中的左腿摆动速度。另外,曹硕在第三跳中的起跳角和腾起角较为合理。相比之下,应对第一、二跳中的起跳角度进行改善。

The jump technique of triple jumper Cao Shuo is analyzed with the methods of documenta-tion,interview and video shooting.The study reveals Caoˊs technical type is hop type,compared with the world excellent triple jumper,the touchdown angle of his jump foot is bigger in the process of the triple jump.In the complete technique,Cao is equipped with better support and stretching ability, and his posture in the air is more reasonable.However,in the second jump,the power of his take -off leg is urgent and whipping magnitude need further strengthening.Compared with the first and third jump,the speed of his swinging leg in the second jump falls obviously,so it is crucial to en-hance the swinging speed of the left leg in the second jump.In addition,his take -off angle and jump angle are rational in the third jump.By contrast,it is necessary to improve the take -off angle in the first and second jump.
