| 采用录像观察法和数理统计法,以2020年东京奥运会60名跆拳道运动员的比赛录像为研究对象,分析、总结世界各地运动员在此次奥运会中应用技战术的特点。认为,若首局得首分,则可增加获胜概率；若首局失首分,则首局往往处于落后状态,此时主动进攻可以增大获胜几率；采用首局得首分战术的运动员带有明显的地域性,欧洲选手使用该战术占比最大为47.36%,非洲选手占比最小为9.09%,并且欧洲选手胜率最高为60.52%,非洲选手胜率最低为9.09%；我国选手孙宏义在使用左开势实战势时技术较为单一,可对此加强训练,郑姝音在使用右闭势实战势时可加强下劈动作的训练。旨在为我国运动员制定科学合理的比赛策略提供数据支持。 |

| Abstract: |
| By using the methods of video observation and mathematical statistics, this paper studies the videos of 60 taekwondo athletes in the 2020 Tokyo Olympics, in order to analyze and summarize the characteristics of skills and tactics used by athletes from all over the world in the Olympic Games. It is believed that if the athlete gets the first score of the first round, the probability of winning can be increased. If the athlete loses the first score of the first round, he may lag behind his opponent in the first round and the active attack can increase the probability of winning. The athletes who use the first-scoring tactics have obvious regional characteristics. European athletes use this tactic for the largest proportion of 47.36%. African athletes use the tactic for the smallest proportion of 9.09%. European athletes have the highest winning rate of 60.52%, and the African players have the lowest winning rate of 9.09%. Chinese athlete Sun Hongyi uses a relatively single technique when using the left-open stance in actual combat, which can be strengthened by training. Zheng Shuyin can strengthen the cut down kick training when using the right-close stance in actual combat. The purpose of this study is to provide data support for Chinese athletes to make scientific and rational competition strategies. |
