Variation in swing mechanics between golfers of different skill levels has been previously reported. To investigate if differences in three-dimensional wrist kinematics and the angle of golf club descent between low and high handicap golfers.
A descriptive laboratory study was performed with twenty-eight male golfers divided into two groups, low handicap golfers (handicap = 0-5, n = 15) and high handicap golfers (handicap ≥ 10, n = 13).
Bilateral peak three-dimensional wrist mechanics, bilateral wrist mechanics at ball contact (BC), peak angle of descent from the end of the backswing to ball contact, and the angle of descent when the forearm was parallel to the ground (DEC-PAR) were determined using an 8 camera motion capture system. Independent t-tests were completed for each study variable (α = 0.05). Pearson correlation coefficients were determined between golf handicap and each of the study variables.
The peak lead arm radial deviation (5.7 degrees, p = 0.008), lead arm radial deviation at ball contact (7.1 degrees, p = 0.001), and DEC-PAR (15.8 degrees, p = 0.002) were significantly greater in the high handicap group.
In comparison with golfers with a low handicap, golfers with a high handicap have increased radial deviation during the golf swing and at ball contact.
先前已有研究报道，不同水平高尔夫球手之间挥杆力学存在差异。本研究旨在探究低差点和高差点高尔夫球手在三维腕关节运动学和高尔夫球杆下降角度方面是否存在差异。
本研究为描述性实验室研究，共纳入 28 名男性高尔夫球手，分为两组：低差点组（差点=0-5，n=15）和高差点组（差点≥10，n=13）。
采用 8 台摄像机运动捕捉系统，分别测定双侧腕关节三维峰值力学、球击瞬间双侧腕关节力学、从上杆结束到球击瞬间的下降峰值角度（DEC-PAR）以及当前臂与地面平行时的下降角度（DEC-PAR）。对每个研究变量进行独立 t 检验（α=0.05）。同时，采用皮尔逊相关系数分析高尔夫差点与每个研究变量之间的关系。
高差点组的优势臂桡侧偏角峰值（5.7 度，p=0.008）、球击瞬间桡侧偏角（7.1 度，p=0.001）和 DEC-PAR（15.8 度，p=0.002）显著大于低差点组。
与低差点高尔夫球手相比，高差点高尔夫球手在挥杆和击球瞬间桡侧偏角更大。
