PURPOSE This study aimed to compare and analyze the game content of the “3-rounds, 2-win system” matches before and after the rule revision implemented in 2022. METHODS This study covered 72 matches from the 2019 Rome World Championships Grand Prix, 92 matches from the Sofia World Championship Grand Prix, and 173 matches from the 2022 Rome World Championships Grand Prix. In total, 337 game videos were analyzed to assess the players‘ game content before and after the rule revision. RESULTS Analyzing the basic skills before and after the revision shows that the frequency of round kicks and pushes was high. Notably, while the frequency of round kicks, which are primarily used by players, decreased after the revision, the scoring success rate increased. CONCLUSIONS Based on the research findings, it is believed that post-revision, players are focusing more on game management aimed at scoring rather than attempting preliminary movements or connecting kicks to deceive their opponents.
