BackgroundA range of innovative performance analysis metrics have been applied in recent years to investigate aspects of football using tempo-spatial and network analyses. These approaches have gained traction within some professional teams to quantify and assess features of collective behaviour. However, metrics employed are rarely created from, or clearly link to, domain expertise and as a result coaches may be hesitant of their value. Therefore, the aim of this study was to identify coach perceptions of spatial temporal and network metrics and identify the feasibility of an iterative and collaborative process to developing metrics.MethodsTwo rounds of semi-structured interviews were conducted with three Scottish youth international UEFA Pro License coaches (age: 47.0 ± 2.7 years) with a focus on aligning metrics with concepts and principles of play. An iterative approach was used centring around spatial-temporal and network metrics and their adaptation. Reflexive thematic analyses were conducted with final metrics categorized as resonant (accurately describing concept or principles of play), relevant (appropriate but with limitations that need improvement), or hesitant (skeptical of usefulness).ResultsAcross the ten recognized principles of play, nine metrics were identified and adapted to varying degrees. Resonant metrics included: network intensity (mobility), distance between defenders (discipline), triangles (support), team length and distance between deepest defender and goal line (depth).ConclusionCoaches recognize principles of play within complex collective behaviour metrics and should be encouraged to collaborate with analysts to develop support systems that may prove to be more valuable and usable.

将新颖的集体行为措施转化为足球教练所理解的比赛概念和原则

背景近年来，一系列创新的表现分析指标已被应用于利用时空和网络分析来研究足球的各个方面。这些方法在一些专业团队中获得了关注，用于量化和评估集体行为的特征。然而，所采用的指标很少是根据领域专业知识创建的，或者与领域专业知识有明显联系，因此教练可能对其价值犹豫不决。因此，本研究的目的是确定教练对时空和网络指标的看法，并确定迭代和协作过程开发指标的可行性。方法对三名苏格兰青年国际欧足联职业执照教练进行了两轮半结构化访谈（年龄：47.0 ± 2.7 岁），重点是将指标与游戏概念和原则保持一致。采用了围绕时空和网络指标及其适应的迭代方法。进行反思性主题分析，最终指标分为共鸣（准确描述游戏的概念或原则）、相关（适当但有需要改进的局限性）或犹豫（对有用性持怀疑态度）。结果在十项公认的游戏原则中，有九个指标已被识别并进行了不同程度的调整。共鸣指标包括：网络强度（机动性）、防守者之间的距离（纪律）、三角形（支持）、球队长度以及最深防守者和球门线之间的距离（深度）。结论教练认识到复杂集体行为指标中的比赛原则，应该受到鼓励与分析师合作开发可能被证明更有价值和更有用的支持系统。
