本研究的目的是：(i)确定在高尔夫挥杆过程中，司机和五铁之间是否存在显著的三维（3D）躯干运动学差异；（ii）确定与杆头速度相关的人体测量学、生理学和躯干运动学变量。收集了15名低差点男性高尔夫球手（差点=2.5 +/- 1.9）的躯干运动范围和挥杆运动数据。数据采集采用10个摄像机运动捕捉系统，工作频率为250Hz。球杆头速度和球速度的数据通过实时发射监视器收集。配对t检验显示，9杆之间的高尔夫挥杆运动学差异显著（p0.0019），即躯干和下躯干弯曲/伸展和下躯干轴向旋转。多元回归分析分别解释了驾驶员和五铁杆头速度方差的33.766.7%，树干和下树干变量都与杆头速度相关。未来的研究应该考虑上肢的作用和高尔夫球杆的可修改特性，尤其是在发展杆头速度方面。
The aims of this study were (i) to determine whether significant three-dimensional (3D) trunk kinematic differences existed between a driver and a five-iron during a golf swing; and (ii) to determine the anthropometric, physiological, and trunk kinematic variables associated with clubhead speed. Trunk range of motion and golf swing kinematic data were collected from 15 low-handicap male golfers (handicap=2.5 +/- 1.9). Data were collected using a 10-camera motion capture system operating at 250Hz. Data on clubhead speed and ball velocity were collected using a real-time launch monitor. Paired t-tests revealed nine significant (p0.0019) between-club differences for golf swing kinematics, namely trunk and lower trunk flexion/extension and lower trunk axial rotation. Multiple regression analyses explained 33.766.7% of the variance in clubhead speed for the driver and five-iron, respectively, with both trunk and lower trunk variables showing associations with clubhead speed. Future studies should consider the role of the upper limbs and modifiable features of the golf club in developing clubhead speed for the driver in particular.
