本研究的目的是确定动力学因素对骨盆的角速度约其纵轴（骨盆轴向角速度）在高尔夫挥杆。31名右手熟练高尔夫球手（差点，3.5±1.8）与驾驶员一起挥杆。使用光学运动分析系统和两个测力平台收集运动学和动力学数据。计算了影响骨盆轴向角加速度的动力学因素（即关节扭矩、重力、运动相关力和惯性力）。本研究表明，左（铅）髋屈肌和内收肌扭矩以及右（trail）髋伸肌和外展肌扭矩被确定为骨盆轴向角速度的主要贡献者。这些髋关节扭矩对骨盆的作用不是同步的，而是顺序的。虽然膝关节力矩对骨盆轴向角速度的直接贡献很小，但膝关节力矩可能通过调节关节姿势来支持大的髋关节力矩的产生。这些结果表明，下肢各节段的功能协调以及关节力矩的大小在骨盆旋转中起着重要作用。
The purpose of this study was to identify the dynamic factors contributing to pelvis angular velocity about its longitudinal axis (pelvis axial angular velocity) during the golf swing. Thirty-one right-handed skilled golfers (handicap, 3.5±1.8) performed swings with a driver. The kinematic and kinetic data were collected using an optical motion analysis system and two force platforms. The dynamic factors (ie, joint torque, gravitational force, motion-dependent forces and inertia forces) contributing to pelvis axial angular acceleration were calculated. The present study revealed that the left (lead) hip flexor and adductor torques as well as the right (trail) hip extensor and abductor torques were identified as the main contributors to pelvis axial angular velocity. These hip joint torques contributed not synchronously but sequentially to the pelvis. Although the knee joint torques contributed little to pelvis axial angular velocity directly, the knee joint torques might support the generation of large hip joint torques by regulating joint postures. These findings indicate that the functional coordination of the lower limb segments as well as the magnitude of the joint torques play an important role in rotating the pelvis.
