摘要在高尔夫运动中，与大多数其他运动不同，个人表现并不是球员之间直接互动的结果。相反，决策和表现受到许多制约因素的影响，这些因素影响着每一次击球。这项研究考察了2011年PGA巡回赛高尔夫球手在逐一击球的稳定性和变异性方面的表现。稳定性和可变性分别用递归量化分析(RQA)和标准差进行评价。大约10%的镜头由短的稳定阶段组成(每个稳定阶段3.7±1.1次)。稳定阶段倾向于由典型表现的镜头组成，而不是糟糕或特殊的镜头；这一发现对所有镜头类别都是一致的。总体而言，稳定性指标与锦标赛成绩无关。所有击球的可变性与锦标赛的表现无关；然而，发球区和近距离击球的可变性高于其他击球类别。此外，发球区击球的可变性与锦标赛的地位有关：可变性越小，锦标赛排名越好。本研究结果显示，PGA巡回赛高尔夫球的表现是混乱的。业余高尔夫表演的结构是否具有普遍性，还需要进一步的研究。
ABSTRACT In golf, unlike most other sports, individual performance is not the result of direct interactions between players. Instead decision-making and performance is influenced by numerous constraining factors affecting each shot. This study looked at the performance of PGA TOUR golfers in 2011 in terms of stability and variability on a shot-by-shot basis. Stability and variability were assessed using Recurrence Quantification Analysis (RQA) and standard deviation, respectively. About 10% of all shots comprised short stable phases of performance (3.7 ± 1.1 shots per stable phase). Stable phases tended to consist of shots of typical performance, rather than poor or exceptional shots; this finding was consistent for all shot categories. Overall, stability measures were not correlated with tournament performance. Variability across all shots was not related to tournament performance; however, variability in tee shots and short approach shots was higher than for other shot categories. Furthermore, tee shot variability was related to tournament standing: decreased variability was associated with better tournament ranking. The findings in this study showed that PGA TOUR golf performance is chaotic. Further research on amateur golf performance is required to determine whether the structure of amateur golf performance is universal.
