This study aimed to analyze the distribution of judo matches in the Tokyo 2020 Olympic Games, considering matches in the regular duration (≤4 min) and during the extra time (the golden score) according to sex, scores, penalties, phases of competition, weight categories, and judo techniques. The data were extracted from the Official Results Books of the Olympic Games in Tokyo 2020. The combats were divided in matches that were finished in the regular duration and that were finished by the golden score, with a total of 450 matches. The Chi-square test was used to identify the association between all variables and different groups of matches duration, with the level at < 0.05. The main results demonstrated significant association, considering sex and frequency of matches in the regular time (χ2 = 6.59; = 0.010) for female athletes. The majority of matches ended in the 3-4 min (χ2 = 204.16; < 0.001), scores were mostly awarded in the regular time and penalties in the golden score (χ2 = 48.72; < 0.001), and few matches ended by the golden score for heavyweight athletes (χ2 = 15.16; = 0.019). Therefore, a high number of matches ended in the golden score in the Olympic Games Tokyo 2020, with a high number of penalties in this competition.
本研究旨在分析2020年东京奥运会柔道比赛的分布情况，考虑按性别、得分、罚分、比赛阶段、体重级别和柔道技术划分的常规时长（≤4分钟）比赛和加时赛（黄金得分）中的比赛。数据从2020年东京奥运会官方成绩册中提取。比赛分为在常规时长内结束的比赛和通过黄金得分结束的比赛，共有450场比赛。采用卡方检验来确定所有变量与不同比赛时长组之间的关联，显著性水平为<0.05。主要结果表明，对于女运动员，考虑性别和常规时间内的比赛频率存在显著关联（χ2 = 6.59；P = 0.010）。大多数比赛在3 - 4分钟内结束（χ2 = 204.16；P < 0.001），得分大多在常规时间判给，罚分在黄金得分时判给（χ2 = 48.72；P < 0.001），重量级运动员通过黄金得分结束的比赛很少（χ2 = 15.16；P = 0.019）。因此，在2020年东京奥运会上，大量比赛通过黄金得分结束，且该比赛中罚分数量较多。
