The competition and physical fitness test results of the 2020 National Taekwondo Championship Series were analyzed using curve fitting, linear regression, and other statistical methods. As far as we know, it is the first Taekwondo competition that uses physical fitness test (PFT) scores as the 8-in-4 selection criteria. The results show that the probability of the final total score of the series of championships entering the top 8 or top 3 is exponentially related to PFT results. It finds that athletes with better PFT scores are more likely to enter the quarterfinals. Among athletes entering the semifinals, the athlete with the best physical fitness has the greatest probability of winning the championship. The difference in physical fitness between athletes is mainly reflected in the 30-meter sprint. Overall, the competitive performance of professional Taekwondo athletes is significantly positively correlated with their physical fitness, especially for female Taekwondo athletes. Through the results obtained, it is concluded that Taekwondo athletes need to strengthen physical training, specifically enhancing the explosive power.
运用曲线拟合、线性回归等统计方法，对 2020 年全国跆拳道冠军系列赛的竞赛成绩与体能测试成绩进行分析。据我们所知，这是首次将体能测试（PFT）成绩作为“8 进 4”选拔标准的跆拳道比赛。结果表明，系列锦标赛决赛总积分进入前 8 名或前 3 名的概率与 PFT 成绩呈指数关系。研究发现，PFT 成绩较好的运动员更有可能进入四分之一决赛。在进入半决赛的运动员中，体能最好的运动员获得冠军的概率最大。运动员之间的体能差异主要体现在 30 米冲刺上。总体而言，专业跆拳道运动员的竞技表现与其体能呈显著正相关，尤其是对于女性跆拳道运动员。通过获得的结果可以得出结论，跆拳道运动员需要加强体能训练，特别是增强爆发力。
