在基于群体的分析中，权重转移被认为是重要的。本研究的目的是通过在个人基础上检查高尔夫挥杆中体重转移的重要性来扩展这项工作。5名职业和业余高尔夫球手与司机一起进行了50次挥杆，将球击入网中。球手的压力中心位置和速度与击球线平行，在8个挥杆事件中由两个测力板测量，这些挥杆事件由高速视频识别。利用回归统计检验了这些参数与球接触杆头速度之间的关系。结果确实支持使用基于群体的分析，所有高尔夫球手都返回了显著的关系。然而，结果也是因人而异的，高尔夫球手回答了不同的重要因素组合。此外，在基于群体的分析中未确定的因素在个体基础上是显著的。最一致的关系是更大的体重转移范围与更大的杆头速度相关（p < 0.05）。所有高尔夫球手在挥杆活动中体重转移率也至少有一个显著相关（p < 0.01）。以个人为基础的分析应该成为以运动技能为基础的生物力学分析的一部分。
Weight transfer has been identified as important in group-based analyses. The aim of this study was to extend this work by examining the importance of weight transfer in the golf swing on an individual basis. Five professional and amateur golfers performed 50 swings with the driver, hitting a ball into a net. The golfer's centre of pressure position and velocity, parallel with the line of shot, were measured by two force plates at eight swing events that were identified from high-speed video. The relationships between these parameters and club head velocity at ball contact were examined using regression statistics. The results did support the use of group-based analysis, with all golfers returning significant relationships. However, results were also individual-specific, with golfers returning different combinations of significant factors. Furthermore, factors not identified in group-based analysis were significant on an individual basis. The most consistent relationship was a larger weight transfer range associated with a larger club head velocity (p < 0.05). All golfers also returned at least one significant relationship with rate of weight transfer at swing events (p < 0.01). Individual-based analysis should form part of performance-based biomechanical analysis of sporting skills.
