This study is a preliminary investigation into the use of cluster analysis to determine if different putting techniques existed in a group of club level golfers. Putting at a hole 4 m away, the performances of 34 experienced golfers (age 55.3 ± 17.8 years and handicap 15.3 ± 6.9, range 3-27) were analysed using putter head kinematic and centre of pressure data. Two distinct putting techniques were identified (named as Arm putting and Body putting), this being the first time different putting techniques have been reported in the research literature. These techniques were defined by parameters related solely to movement of the centre of pressure along the line of the putt. Some players (17 of 34) moved between techniques when performing their putting trials. Neither technique produced more accurate putt results (P = 0.783). Putting technique was further analysed after grouping players according to handicap (similar skill level) or accuracy (similar putting performance). The lack of significant findings when players were re-analysed according to handicap or accuracy highlights the importance of the correct methodological approach to detecting technique differences.
本研究初步探讨了聚类分析在确定一群高尔夫球手是否存在不同推杆技术中的应用。在距离球洞 4 米远的地方进行推杆，对 34 名经验丰富的高尔夫球手（年龄 55.3±17.8 岁，差点 15.3±6.9，范围 3-27）的推杆头运动学和压力中心数据进行了分析。确定了两种不同的推杆技术（分别命名为手臂推杆和身体推杆），这是研究文献中首次报道不同的推杆技术。这些技术仅通过与推杆线沿线的压力中心运动相关的参数来定义。一些球员（34 名球员中的 17 名）在进行推杆试验时在技术之间转换。两种技术都没有产生更准确的推杆结果（P=0.783）。根据差点（相似的技能水平）或准确性（相似的推杆表现）对球员进行分组后，进一步分析了推杆技术。根据差点或准确性对球员重新进行分析时，没有发现显著差异，这突出了采用正确的方法来检测技术差异的重要性。
