Abstract
This study explored the frequency and tendencies of tactical behaviors exhibited during judo matches in order to contribute to the improvement of sports performance in judo. All matches from the All Japan Weight Breaking Championship 2024 were analyzed. Based on previous studies and discussions with co-researchers, nine behaviors in two phases were set as the analytical framework. The results showed that “engaging” was the most frequent behavior with 278 occurrences (31.4%) when the athletes were not grappling. After grappling, “breaking /releasing grip” was the most frequent with 394 occurrences (41.6%). When analyzed by gender, “repelling,” “shifting sleeve,” and “breaking /releasing grip” were significantly more frequent in males, while “engaging,” “avoiding,” and “pushing/holding” were significantly more frequent in females. Comparisons between weight classes revealed that lighter weight classes exhibited more behaviors aimed at maintaining distance from the opponent, while heavier weight classes exhibited more behaviors aimed at gaining a superior position after grappling. Through this study, we were able to clarify the characteristics of tactical behaviors during matches. Additionally, we were able to identify the similarities and differences in performance structures between genders and weight classes.
