Abstract：
Recently, a variety of technical approaches in world-class pole-vaulters\' behaviour have been observed. The aim of this study was to investigate the presence of subgroups using different technical approaches and to compare biomechanical performance differences. Biomechanical analysis of performances over 5.00 metres from 99 athletes were clustered with K-means methodology based on the relative position of the top hand at take-off and the direction of the top of the pole from take-off to the maximal pole bending. Analysis revealed four subgroups that were distinguished by higher and lower direction angle and relative position values. Despite differences in technique, the analysis did not reveal significant differences between these four groups in performance, take-off speed, or athlete anthropometrics. Nevertheless, these clusters showcased variations in pole-athlete interactions and pole bending, suggesting different strategies and physical requirements associated with each approach. Cluster 2 characterised the classical technique with a high direction angle and a take-off position close to the vertical plane. Cluster 4 displayed a technique with a low take-off angle, suggesting the influence of athletes like Lavillenie, in deviating from the conventional model. Understanding and categorising athletes based on their preferred technique can aid coaches in providing tailored instructions, leading to performance improvements.
摘要：
最近,已经观察到世界级撑杆跳高运动员行为的各种技术方法。这项研究的目的是使用不同的技术方法调查亚组的存在，并比较生物力学性能差异。根据起飞时顶手的相对位置以及从起飞到最大杆弯曲的杆顶部的方向，使用K均值方法对99名运动员超过5.00米的表现进行了生物力学分析。分析显示了四个亚组，它们通过较高和较低的方向角和相对位置值来区分。尽管技术不同,分析没有发现这四组在表现上有显著差异，起飞速度,或运动员人体测量学。然而，这些集群展示了杆运动员互动和杆弯曲的变化，建议与每种方法相关的不同策略和物理要求。集群2以经典技术为特征，具有高方向角和靠近垂直平面的起飞位置。第4组展示了一种低起飞角度的技术，暗示像Lavillenie这样的运动员的影响，偏离了传统的模式。根据他们喜欢的技术理解和分类运动员可以帮助教练提供量身定制的指导，导致性能改进。
