Abstract

The occurrence of squad rotation in football and its effect on team performance in terms of points have not been comprehensively studied in football performance analysis literature. This study deploys a data-driven approach to examine the occurrence of squad rotation across English, French, Italian and Spanish leagues over multiple seasons. It aims to establish the relationship observed between average squad rotations in starting lineups and end-of-season points. A total of 16,720 matches dating from the 2010/11 to 2021/22 seasons were analysed for average rotations in each team involved and the respective team's end of season points, alongside contextual information such as injury and logarithmic market value. A linear mixed-effects model was used to study this relationship, with each variable as well as interaction of variables being analysed for fixed effects. The results show that a significant relationship exists between team success, average rotation of the team per match and market value of the team, while no significant effects are found for injuries. The results describe how universally deploying squad rotation may not yield higher points over a season, but also shows how the effect of rotations on team success keep increasing as the market value of teams increases.

"砍伐与改变":考察欧洲顶级足球联赛中的球队轮换及其对球队表现的影响
足球比赛中的阵容轮换及其对球队积分表现的影响在足球表现分析文献中尚未得到全面研究。本研究采用数据驱动的方法,研究了多个赛季中英格兰、法国、意大利和西班牙联赛的球队轮换情况。其目的是建立观察到的首发阵容中平均轮换阵容与赛季末积分之间的关系。研究人员对 2010/11 至 2021/22 赛季的 16,720 场比赛进行了分析,分析了每支参赛球队的平均轮换阵容和各自球队的赛季末积分,以及伤病和市场价值对数等背景信息。研究采用线性混合效应模型,对每个变量以及变量之间的交互作用进行固定效应分析。结果显示,球队的成功率、球队每场比赛的平均轮换次数和球队的市场价值之间存在显著关系,而伤病则没有发现显著影响。结果表明,在一个赛季中,普遍部署轮换阵容未必能获得更高的积分,但同时也表明,随着球队市场价值的增加,轮换阵容对球队成功的影响也在不断增加。

期刊介绍: The International Journal of Sports Science & Coaching is a peer-reviewed, international, academic/professional journal, which aims to bridge the gap between coaching and sports science. The journal will integrate theory and practice in sports science, promote critical reflection of coaching practice, and evaluate commonly accepted beliefs about coaching effectiveness and performance enhancement. Open learning systems will be promoted in which: (a) sports science is made accessible to coaches, translating knowledge into working practice; and (b) the challenges faced by coaches are communicated to sports scientists. The vision of the journal is to support the development of a community in which: (i) sports scientists and coaches respect and learn from each other as they assist athletes to acquire skills by training safely and effectively, thereby enhancing their performance, maximizing their enjoyment of the sporting experience and facilitating character development; and (ii) scientific research is embraced in the quest to uncover, understand and develop the processes involved in sports coaching and elite performance.
