摘　　要：本文采用文献资料法、运动视频分析法、数理统计法等研究方法,以东京奥运会男子三级跳远运动员为研究对象进行对比分析。结果表明:东京奥运会,国内运动员踏板准确性较差,起跳腿蹬伸力量不足,蹬伸不够,蹬伸时间较短,肌肉收缩力量不强,腿部力量没有完全得到发挥,但其积极着地,对三跳节奏和比例掌握控制能力较好,有利于取得好的成绩。本文研究东京奥运会男子三级跳远运动员关键技术存在的优缺点,旨在为教学训练提供参考,我国发展三级跳远运动助力。By using the methods of literature,sports video analysis and mathematical statistics,this paper makes a comparative analysis of the men's triple jumpers at the 2021 Olympic Games in Tokyo.The results reveal that at the Tokyo Olympic Games,the accuracy of htting the takeof board of domestic athletes was low.The strength of the take-off leg when hitting and hopping was insuffcient;the hit and hop time was short.The muscle contraction strength was not strong,and the leg strength was not fully utilized.Their active landing,and the ability to control the pace and step distance of the triple jump was good,which was conducive to the performance of the resuls.The performance of the athletes at the 2021 Olympics needs to be improved.This peper studies the advantages and disadvantages of the key techniques of the men's triple jumpers at the Olympics in Tokyo,in an effort to provide a theoretical basis for teaching and training,and to help the development of the triple jump discipline in China.
