我们的目的是澄清性别群体之间的足球脚背踢动力学的差异。采用运动捕捉系统（500 Hz）记录7名女运动员（身高160.3 ± 6.1 cm，体质量54.3 ± 5.2 kg）和7名男运动员（身高173.0 ± 5.9 cm，体质量70.0 ± 9.0 kg）的脚背踢腿动作。计算出踢腿的关节力矩，并按体重和身高标准化。统计参数映射被用来比较两组之间的整个踢运动。女性运动员明显较慢的合成球速最有可能是由她们明显较慢的助跑速度、较短的腿长和较低的足球速度比来解释的。女子运动员在踢腿后半段膝关节力矩显著较小（80-86%）。此外，显着较小的正工作所做的膝关节伸展力矩和工作的比例（膝关节伸展/髋关节屈曲）被发现在女性运动员。这些结果表明，膝关节伸直力矩动作被抑制是女运动员脚背踢腿动作的一个关键动力学特征，为了补偿膝关节伸直力矩动作，她们更多地依靠髋关节屈曲力矩做功来完成脚背踢腿动作。
We aimed to clarify the differences in soccer instep kicking dynamics between sex groups. The instep kicking of seven female (height: 160.3 ± 6.1 cm; mass: 54.3 ± 5.2 kg) and seven male (height: 173.0 ± 5.9 cm; mass: 70.0 ± 9.0 kg) players were recorded by a motion capture system (500 Hz). Joint moments of the kicking leg were computed and normalized by the body mass and height. Statistical parametric mapping was used to compare the entire kicking motion between the two groups. Significantly slower resultant ball velocity seen in female players was most likely explained by their significantly slower run-up velocity, shorter leg length and lower foot–ball velocity ratio. Female players exhibited significantly smaller knee joint moment in the latter part (80–86%) of kicking. Also, significantly smaller positive work done by knee extension moment and the ratio of work (knee extension/hip flexion) were found in female players. These results suggested that the suppressed knee extension moment action was identified as a key kinetic characteristic in the instep kicking of female players, and to compensate for this action, they more rely on the work due to hip flexion moment to execute the instep kicking.
