The purpose of this research is to investigate the factors affecting the performance capability of lunge movements by performing lunge movements which are commonly used as a method of instant physical movement in sports with a kinetic analysis including an EMG analysis. This research targeted 14 skilled fencers and made the subjects perform kick-lunges which allow them to go farthest from their positions and performed an analysis on such, applying a 3D motion analysis system and an EMG system. The subjects performed kick-lunges in two movements; one with a preliminary movement and the other without it and those are performed with both dominant leg and non-dominant leg. The result of this research is as follows. The lunges with a preliminary movement showed higher performance capability than those without it. Furthermore, as the level of skills gets higher, the length of lunges gets longer, and it seemed that a tactical mechanism shortening exercise performance times was used as a mechanism to control the impulse coming from such lengthened lunges. In addition, a difference appeared in mechanical factors such as moment and power in a dominant leg movement and it seemed to result from a difference in an functional capability using muscles.
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.
