World Rank List of Male Judokas and its Relation to Results of Tokyo Olympic Games (2020)

Aim: This research aimed to identify the relationship between male judokas' rank according to World Ranking List (WRL) and their results in Tokyo Olympic Games (2020) competitions. Methods: The researchers used the descriptive approach to analyze competition data of Tokyo Olympic Games (2020) for (201) male judokas in all weight categories with total of (222) matches. Win/Lose frequency and percentages were extracted for high-rank and low-rank judokas according to WRL. Chi2 was used for identifying correlations between the judokas' ranks on WRL and their match results (win/lose). Results: results indicated that high-rank judokas won (162) matches (72%) as Chi2 value reached (48.005) which was statistically significant on P≤0.01 in favor of high-rank judokas. Winning percentages for judokas in (-60, -66, -73, -81, -90, -100 and +100) kg weight categories were (80.77%, 66.67%, 76.92%, 65.79%, 75%, 75% and 72%) respectively. Results of Chi2 indicated statistically significant correlations on P≤0.01 in favor of high-rank judokas in (-60, -73, -90, -100 and +100) kg, while the same value was significant on P≤0.05 for (-66 and -81) kg weight categories. Accordingly, the researchers concluded a statistically significant correlation between the judokas' ranking and their results in Tokyo Olympic Games (2020) as the higher the rank on WRL the higher the chance for a judoka to gain an advanced rank in the Olympics. It is also noticed that lower-rank judokas may have the chance to win, despite the vast gap in ranking, if they have the required abilities, talent and motivation to win
