研究目的：探讨男女足球运动员脚背踢脚动作下肢段动力学的差异。脚背踢运动的七名女性和七名男性大学足球运动员被捕获在500赫兹。计算了小腿角速度、膝关节力矩和作用在小腿上的相互作用力矩。离散变量比较采用双样本t检验，时间序列变化比较采用统计参数映射。虽然女性运动员保持了相当的小腿角速度的大小，他们表现出显着较低的膝盖伸展力矩在踢的后半部分和显着较小的向前角冲动，由于这一时刻。与此相反，女性球员被发现有一个相当的幅度的角冲动，由于向前分量的相互作用的时刻，男性球员。最终，女性运动员的角度冲动（向前交互力矩/膝关节伸展力矩）的比例明显大于男性运动员。可以认为，作用在女性运动员小腿上的相互作用力矩的前向分量可以补偿其膝关节伸展力矩的减少，从而实现与男性运动员相当的小腿角速度。
We aimed to clarify the difference in lower leg segment kinetics of soccer instep kicking between female and male players. Instep kicking motions of seven female and seven male university soccer players were captured at 500 Hz. Lower leg angular velocity, knee joint moment and the interaction moment acting on the lower leg were calculated. Discrete variables were compared using two sample-t-test, and statistical parametric mapping were used to compare the time-series changes between the two groups. Although female players maintained a comparable magnitude of lower leg angular velocity, they exhibited significantly lower knee extension moment in the latter part of kicking and significantly smaller forward angular impulse due to that moment. In contrast, female players were found to have a comparable magnitude of angular impulse due to forward component of interaction moment to that of male players. Eventually, female players come to have significantly larger ratio of angular impulses (forward interaction moment/knee extension moment) than male players. It can be considered that the forward component of interaction moment acting on the lower leg of female players may compensate their reduced exertion of knee extension moment, thereby achieving a comparable lower leg angular velocity to that of male players.
