The Bundesliga made headlines for becoming the first major sports league to return to sport worldwide following COVID-19 lockdown. To-date, there lacks retrospective studies on longitudinal injury rates to elucidate the effect isolation measures had on the health and safety of professional athletes. This study sought to compare injury rates experienced by Bundesliga athletes before and after the COVID-19 lockdown. Data was collected from public injury and player reports regarding the Bundesliga, with injury defined as trauma resulting in loss of game time. Descriptive statistics were used to present differences in injury incidence between all Bundesliga Match days pre- and post-lockdown. Between the league's resumption and completion on May 16 and June 27, 2020, injuries occurred in 21 forwards (FW), 11 central midfielders (CM), 12 wide midfielders (WM), 16 central defenders (CD), 6 fullbacks (FB), and 2 goalkeepers. Players had 1.13 (95% CI 0.78, 1.64) times the odds of being injured following the COVID-19 lockdown, with a 3.12 times higher rate of injury when controlling for games played compared to injury rates pre-lockdown (0.84 injuries per game vs. 0.27 injuries per game). The most frequent injury group was muscular injuries with 23 injuries total, with 17% of athletes experiencing injury during their first competitive match following lockdown. Injury rate increased over 3-fold following COVID-19 lockdown. Athletes did not experience an increased rate of injury with more cumulative competitive matches played. High injury incidence for players yet to complete their first competitive match may imply suboptimal sport readiness following home confinement.
德甲联赛成为新冠疫情封锁后全球首个恢复赛事的大型体育联赛，成为头条新闻。迄今为止，缺乏关于纵向受伤率的回顾性研究来阐明隔离措施对职业运动员健康和安全的影响。本研究旨在比较新冠疫情封锁前后德甲运动员的受伤率。数据收集自德甲联赛公开的伤病和球员报告，伤病定义为导致比赛时间损失的创伤。使用描述性统计来呈现封锁前和封锁后所有德甲比赛日之间受伤发生率的差异。在2020年5月16日至6月27日联赛恢复至结束期间，21名前锋（FW）、11名中场球员（CM）、12名边锋（WM）、16名中后卫（CD）、6名边后卫（FB）和2名守门员受伤。新冠疫情封锁后球员受伤的几率是之前的1.13倍（95%置信区间0.78，1.64），与封锁前的受伤率相比，在控制比赛场次后受伤率高出3.12倍（每场比赛0.84次受伤 vs. 每场比赛0.27次受伤）。最常见的伤病类型是肌肉损伤，总计23例，17%的运动员在封锁后的首场比赛中受伤。新冠疫情封锁后受伤率增加了3倍多。随着累计比赛场次增加，运动员的受伤率并未上升。尚未完成首场比赛的球员受伤发生率较高，这可能意味着居家隔离后运动准备状态不佳。
