The purpose of this study was to investigate the reaction time and muscle activity and compare the movement among genders during Marche-fente. The results showed that male athletes had faster reaction times compared to female athletes. Additionally, women tended to activate knee flexors instead of knee extensors when moving the center of mass or generating a greater force. Therefore, exercises that activate knee extensors are required for females.
Reaction time is important to determine the performance of fencing. The purpose of this study was to investigate the reaction time and muscle activity and compare the movement among genders during Marche-fente. Fifteen Korean national Fleuret fencing athletes participated and were instructed to perform Marche-fente. Reaction time was measured with Plug & Play equipment and muscle activation was obtained by electromyography. The male athletes (0.94 +/- 0.08 s) were faster than female athletes, who a performance of 1.03 +/- 0.05 s. As the knee extensors activation was increased, the movement and response time was shorter (rectus femoris (RF); r = -0.526, p < 0.05, vastus lateralis oblique (VLO); r = -0.628, p < 0.05). In phase 1, men activated more knee extensors in the dominant leg, whereas the activation of knee flexors was increased to maintain a stable posture in women. Additionally, women used other muscles instead of large muscles such as RF and VLO in phase 2. In conclusion, female athletes activated knee flexors rather than knee extensors when moving the center of mass or generating a greater force. Less use of knee extensors is associated with knee injuries; therefore, exercise which activates knee extensors is required for females.
