研究了髋关节直线运动对足球脚背踢球下肢动力学的影响。五名技术高超的俱乐部球员自愿参加，他们的踢腿动作以200 Hz的频率被三维捕捉。根据Putnam（1991）的方法，提取了作用在小腿上的由髋部线加速度（MHLA）引起的相互作用力矩。MHLA在最后阶段的踢腿过程中表现出较大的正力矩，以增加小腿角速度。MHLA的这种有效作用主要是由髋关节的向上加速度引起的。由于臀部运动完全是由于支撑腿的运动，因此可以假设MHLA的有效动作最可能是由于支撑腿运动，例如在踢腿期间的膝盖伸展运动。
The influence of the hip linear motion on the lower leg kinetics was examined for soccer instep kicking. Five highly skilled club players volunteered and their kicking motion was three-dimensionally captured at 200 Hz. According to the procedure of Putnam (1991), the interactive moment due to the hip linear acceleration (MHLA) acting on the lower leg was extracted. The MHLA exhibited a large positive moment to increase the lower leg angular velocity during the final phase of kicking. This effective action of the MHLA was mostly caused by the upward acceleration of the hip. As the hip motion is exclusively due to the motion of the support leg, it can be assumed that the effective action of the MHLA is most likely due to the support leg motions such as the knee extension motion during kicking.
