The Coronavirus Disease-19 (COVID-19) pandemic forced the Norwegian male premier league football season to reschedule, reducing the fixture calendar substantially. Previous research has shown that a congested match schedule can affect injury rates in professional football. Therefore, we aimed to investigate whether the Norwegian premier league teams suffered more injuries in the more match congested 2020 season than in the regular 2019-season. We invited all teams having participated in both seasons to export their injury data. Only teams that used the same medical staff to register injuries in both seasons were included, and to maximize data comparability between seasons, we applied a time-loss injury definition only. Seven of 13 teams agreed to participate and exported their injury data. Both seasons had 30 game weeks, but the 2020 season was 57 days shorter than the 2019 season. The match injury incidence did not differ significantly [incidence rate ratio 0.76 (0.48-1.20; = 0.24) in the 2020 season compared to the 2019 season. Furthermore, we found no differences in the number of injuries, days lost to injury, matches missed to injury, or injury severity. We could not detect any differences between the two seasons, suggesting the congested match calendar combined with the safety measures in the 2020 season can be a safe alternative in future seasons.
新型冠状病毒肺炎（COVID-19）疫情迫使挪威男子足球超级联赛赛季重新安排，大幅减少了赛程。此前的研究表明，密集的比赛赛程会影响职业足球的受伤率。因此，我们旨在调查挪威超级联赛球队在比赛更为密集的2020赛季是否比正常的2019赛季受伤更多。我们邀请了参加过这两个赛季的所有球队导出他们的伤病数据。仅纳入在两个赛季中使用相同医务人员记录伤病情况的球队，并且为了使两个赛季的数据具有最大可比性，我们仅采用了失能伤病的定义。13支球队中有7支同意参与并导出了他们的伤病数据。两个赛季均有30个比赛周，但2020赛季比2019赛季短57天。与2019赛季相比，2020赛季的比赛伤病发生率没有显著差异[发生率比值为0.76（0.48 - 1.20； = 0.24）]。此外，我们发现在伤病数量、伤病导致的缺阵天数、因伤错过的比赛场次或伤病严重程度方面没有差异。我们未检测到两个赛季之间存在任何差异，这表明2020赛季密集的比赛赛程与安全措施相结合在未来赛季可能是一种安全的选择。
