Abstract
Background: In the 2019/2020 football season, an increase from three to five substitutions was implemented in European football to help players manage a congested match calendar following lockdown due to the COVID-19 pandemic. In this study, we aimed to determine injury rates before and after implementation of five substitutions. Secondary objectives included characteristics and duration of injury and associated risk factors.
Materials and methods: A retrospective review of players injured while playing in the first division of the Spanish professional football league (La-Liga) during the 2017/2018, 2018/2019, 2022/2023, and 2023/2024 seasons were identified from an online database, Transfermarkt. Injury- and player-related characteristics, as well as game play before and after the implementation of five substitutions, were studied. Multivariate regression models were used to assess complications, adjusting for age, minutes played, and appearances.
Results: The overall incidence during the study period was 0.76 injuries per player-season. A total of 1,268 injuries were reported prior to the rule change with an incidence of 0.94 injuries per player-season compared to 711 reported injuries with an incidence of 0.57 injuries per player-season after. There were significantly decreased odds of multiple injuries (odds ratio [OR]: 0.68; 95% CI [0.56, 0.82]; P<0.001) and muscle injuries (OR: 0.72; 95% CI [0.59, 0.87]; P<0.001) after the increase in substitutions.
Conclusion: Implementation of five substitutions was associated with significantly decreased injury rates in LaLiga. Additionally, players had significantly lower odds of sustaining multiple injuries and muscle injuries. [Orthopedics. 202x;4x(x):xx-xx.].
背景：在2019/2020足球赛季，欧洲足球的换人人数从3人增加到5人，以帮助球员管理因COVID-19大流行而封锁的繁忙比赛日程。在本研究中，我们旨在确定实施五次换人前后的损伤率。次要目标包括损伤的特征和持续时间以及相关的危险因素。材料和方法：通过在线数据库Transfermarkt对2017/2018、2018/2019、2022/2023和2023/2024赛季在西班牙职业足球联赛（西甲）一级联赛中受伤的球员进行回顾性分析。研究了与伤病和球员相关的特征，以及实施五次换人前后的比赛情况。多变量回归模型用于评估并发症，调整年龄、上场时间和外表。结果：研究期间的总发生率为0.76人/球员赛季。在规则改变之前，共有1268人受伤，每个球员赛季的受伤率为0.94人，而在规则改变之后，报告的受伤率为711人，每个球员赛季的受伤率为0.57人。多发伤的发生率显著降低(比值比[OR]: 0.68；95% ci [0.56, 0.82]；ppg结论：在西甲联赛中，实施5次换人可以显著降低受伤率。此外，球员遭受多处受伤和肌肉损伤的几率也明显较低。[矫形手术。202 x; 4 x (x): xx-xx。]。
