这项研究的目的是检查在最大限度的脚背踢球时，首选腿和非首选腿的球的释放速度，并将球的速度与踢球动作中观察到的生物力学差异联系起来。七名熟练的足球运动员用偏爱和非偏爱的腿进行最快速度的定位球；他们的动作被以400赫兹的频率拍摄下来。推导了节间运动学和动力学方程。计算足部与球之间的恢复系数，并使用Kin-Com测力仪测量髋屈肌和膝关节伸肌的力量发展速度。与非首选腿相比，由于撞击时的足部速度和恢复系数较高，首选腿获得了更高的球速。这些较高的脚速是由于大腿的角速度所产生的小腿上的较大工作量造成的。在肌力矩和力量发展速度方面没有发现差异。我们的结论是，首选腿和非首选腿之间的最大球速度差异是由较好的节间运动模式和用首选腿踢球时从脚到球的速度转移造成的。
The aims of this study were to examine the release speed of the ball in maximal instep kicking with the preferred and the non-preferred leg and to relate ball speed to biomechanical differences observed during the kicking action. Seven skilled soccer players performed maximal speed place kicks with the preferred and the nonpreferred leg; their movements were filmed at 400 Hz. The inter-segmental kinematics and kinetics were derived. A coefficient of restitution between the foot and the ball was calculated and rate of force development in the hip flexors and the knee extensors was measured using a Kin-Com dynamometer. Higher ball speeds were achieved with the preferred leg as a result of the higher foot speed and coefficient of restitution at the time of impact compared with the non-preferred leg. These higher foot speeds were caused by a greater amount of work on the shank originating from the angular velocity of the thigh. No differences were found in muscle moments or rate of force development. We conclude that the difference in maximal ball speed between the preferred and the non-preferred leg is caused by a better inter-segmental motion pattern and a transfer of velocity from the foot to the ball when kicking with the preferred leg.
