This study examined the fléche behavior of fencing. Participants were middle school and high school fencing athletes, and. 3D imagery and ground reaction force were used to study the knee joint moments. First, the participants leapt forward with their back legs. The forces generated in the ankle joints of the back legs were the internal adduction, the moments of the plantar flexion and the valgus moments. At the ankle joints of the flash workout, middle school fencers showed higher measurements than high school fencers. In the ground reaction, high school students reached the ground in a short period of time. For high school fencers, the ground response was executed in a short time and the role of the ankle joints was relatively reduced. Second, abduction moment appeared in all participants΄ knees. This is because the foot is pulled from the marche and landed at 90°when it touchd the ground. All participants showed extension moments and showed the highest measured values in the knee. Moreover, the measured value of the high school students was larger than that of the middle school students. Consequently, the extension moment plays a very important role in making the body go forward. In the cross section, the external moment appeared with all the participants. However, there was no difference in the measured values. Third, in the hip joint, the participants showed abduction, extension, and medial rotation. The maximum value of abduction was similar. However, junior high students had more abduction moment. On the other hand, the measured value of the extension moment was higher in high school students. This is thought to be the role of the extension moment rather than abduction moment in order to exert a strong leverage in a short time. There was no difference in medial rotation. Fléche motion was compared between male middle school students and male high school students. High-school students had short operating times, and with middle school students the ankle joint played an important role. On the other hand, knee joints played an important role in high school students. Therefore, a highly-skilled person reached the ground in a short time. It is the hip joint that exerts the greatest power on the back of the experimenter's flash motion. The abduction moment of middle school students was large. High school students showed a large extension moment. Therefore, this study found that the role of the hip joint is important for performing fast movements.

본 연구는 펜싱의 플레쉬 동작 시 하지관절모멘트에서 발현되는 힘에 관한 연구로 3차원영상 및 지면반력 데이터를 이용하여 동작을 분석하여 빠르고 정확하게 움직이는 효율적인 동작에 대 한 과학적이고 객관적인 자료를 찾는데 목적이 있다. 이 연구는 남자 중학생과 고등학생 펜싱선수 를 대상으로 플레쉬 동작 시 하지분절에 관한 모멘트를 분석하였다. 플레쉬 동작은 멀리 있는 상대방을 정확하게 찌르기 위한 동작이다. 발목관절에서 중학생이 저 측굴곡, 내전, 외번이 크게 작용하였다. 이는 중학생이 고등학생보다 지면에 작용하는 시간이 길기 때문이다. 무릎관절에서는 고등학생이 내전모멘트가 크게 작용하였다. 무릎의 내전의 힘이 신체를 빠르게 이동시키는데 중요한 역할을 하였다. 고관절에서도 내전모멘트가 신체이동을 빠르게 이동 시키는데 큰 역할을 수행하였으며, 특히, 고등학생은 큰 측정값을 보였다. 따라서 플레쉬 동작에서 고관절의 내전모멘트의 역할이 매우 중요한 역할을 하였다.
