The purpose of this study is to compare the athletes’ scores, penalties and efficiency between of the Olympic and Paralympic Games Rio 2016, and identify which variable determines the winner of the matches. A total of 608 matches in the Olympic and Paralympic Games were analysed. Total relative scores (ippon, wazari and yuko), penalties (shido per match) and efficiency were identified in the categories male and female, Olympic and Paralympic Games, and medallists and non-medallists. The main results showed that the wazari was higher in the Olympic Games (p = 0.05) than in the Paralympic Games (male team); the ippon was higher in the Paralympic Games (p = 0.05) and the shido was higher in the Olympic Games (p = 0.05) (female team). The male Olympic medallists were more efficient (p = 0.01), while the female Paralympic medallists were less punished (p = 0.01). The ippon was the key variable that determined winning in both Olympic and Paralympic matches (p < 0.001). We concluded that male Olympic athletes showed greater efficiency and scores than Paralympians, while the female team presented more scores and fewer penalties. The ippon was the key point that determined victory in most of the matches.

2016年里约奥运会和残奥会

本研究的目的是比较2016年里约奥运会和残奥会运动员的得分，处罚和效率，并确定哪个变量确定比赛的获胜者。共分析了608场奥运会和残奥会比赛。在男子和女子，奥运会和残奥会以及奖牌获得者和非奖牌获得者中确定了总的相对得分（日本，瓦扎里和尤科），罚分（每次比赛的柔道）和效率。主要结果表明，奥运会中的瓦萨里（p = 0.05）高于残奥会（男队）；在残奥会上，日本率较高（p = 0.05），在奥林匹克运动会中shido较高（p = 0.05）（女队）。男性奥林匹克奖牌获得者更有效率（p = 0.01），而残奥会的女性奖牌获得者受到的惩罚更少（p = 0.01）。决定性因素是决定在奥运会和残奥会比赛中获胜的关键变量（p <0.001）。我们得出的结论是，奥运会男运动员表现出比残奥会更高的效率和得分，而女队则表现出更高的得分和更少的处罚。日本是决定多数比赛胜利的关键。
