During practice and competition, golfers are required to use submaximal effort to hit the ball a given distance, i.e., perform a partial shot. While the full golf swing has undergone extensive research, little has addressed partial shots and the biomechanical modifications golfers employ. This study investigates the biomechanical changes between full and partial swings, and determines if the partial swing is a scaled version of the full swing. Using a repeated measures design, 13 male golfers completed a minimum of 10 swings in the full and partial swing conditions, whilst club, ball, kinematic, and kinetic parameters were recorded. Large and statistically significant reductions in body motion (centre of pressure ellipse: 33.0%, = 0.004, = 2.26), combined with moderate reductions in lateral shift (25.5%, = 0.004, = 0.33) and smaller reductions in trunk rotation (arm to vertical at top of backswing: 14.1%, = 0.002, = 2.58) indicate golfers favour larger reductions in proximal measures, combined with diminished reductions as variables moved distally. Furthermore, the partial swing was not found to be a scaled version of the full swing implying a new approach to coaching practices might be considered.
在练习和比赛中，高尔夫球手需要用次最大的力量将球击出给定的距离，即进行部分挥杆。虽然完整的高尔夫挥杆已经经过了广泛的研究，但很少有研究涉及部分挥杆和高尔夫球手采用的生物力学修改。本研究调查了完整挥杆和部分挥杆之间的生物力学变化，并确定部分挥杆是否是完整挥杆的缩放版本。使用重复测量设计，13 名男性高尔夫球手在完整和部分挥杆条件下完成了至少 10 次挥杆，同时记录了球杆、球、运动学和动力学参数。身体运动（压力中心椭圆：33.0%， = 0.004， = 2.26）和横向位移（25.5%， = 0.004， = 0.33）的大幅和统计学显著减少，以及躯干旋转（手臂在背部摆动最高点与垂直的夹角：14.1%， = 0.002， = 2.58）的适度减少表明，高尔夫球手更喜欢近端测量值的较大减少，同时近端变量减少的幅度较小。此外，部分挥杆并未被发现是完整挥杆的缩放版本，这意味着教练实践可能需要考虑新的方法。
