BACKGROUND
The preseason is a crucial time period for professional athletes to prepare for the upcoming season. However, due to the coronavirus 2019 (COVID-19) pandemic, the 2020 National Football League (NFL) preseason was canceled. As the regular season progressed, an increased number of injuries became apparent.
PURPOSE/HYPOTHESIS: The purpose of this study was to compare injury rates between the 2019 and 2020 NFL regular seasons after the canceled 2020 preseason. It was hypothesized that injury rates in the 2020 season would be the same or higher compared with 2019.
STUDY DESIGN
Descriptive epidemiology study.
METHODS
A public database of all 32 NFL teams was used to examine the movement of all players to injured reserve status as well as every player who missed a regular-season game due to injury for both the 2019 and the 2020 NFL regular seasons. Data collection consisted of tallying the total number of reported musculoskeletal injuries for each team. Comparisons of injury rates between the 2 seasons were made using a Wilcoxon signed-rank statistical analysis.
RESULTS
The total number of musculoskeletal injuries was 632 for the 2019 regular season and 765 for the 2020 regular season ( = .0324). Compared with 2019, statistically significant increases in injury rates in 2020 were seen for calf or Achilles tendon strain (17 vs 39; = .009), groin injury (25 vs 46; = .018), and anterior cruciate ligament tear (14 vs 29; = .016). There were several other increased trends in soft tissue injury rates in the 2020 season (eg, hamstring injury [87 vs 114; = .085]); however, these did not reach statistical significance.
CONCLUSION
This study showed a significant increase in total injuries during the 2020 COVID-19-affected NFL regular season compared with 2019. Several major soft tissue injuries reached statistical significance in their increase from 2019 to 2020 after the cancellation of the 2020 preseason due to COVID-19. These findings suggest that organized team preseason training and conditioning could have an effect on the prevention of sport-related injury at the highest level.
背景
季前赛是职业运动员为即将到来的赛季做准备的关键时期。然而，由于2019年冠状病毒病（COVID-19）大流行，2020年国家橄榄球联盟（NFL）季前赛被取消。随着常规赛的推进，受伤人数明显增加。
目的/假设：本研究的目的是比较2020年季前赛取消后2019年和2020年NFL常规赛的受伤率。研究假设是，与2019年相比，2020赛季的受伤率将相同或更高。
研究设计
描述性流行病学研究。
方法
使用一个包含所有32支NFL球队的公共数据库，来调查2019年和2020年NFL常规赛中所有进入伤病储备状态的球员以及因伤错过常规赛的每一位球员的情况。数据收集包括统计每支球队报告的肌肉骨骼损伤总数。使用Wilcoxon符号秩统计分析对两个赛季的受伤率进行比较。
结果
2019年常规赛肌肉骨骼损伤总数为632例，2020年常规赛为765例（P = ．0324）。与2019年相比，2020年小腿或跟腱拉伤（17例对39例；P = ．009）、腹股沟损伤（25例对46例；P = ．018）和前交叉韧带撕裂（14例对29例；P = ．016）的受伤率在统计学上显著增加。2020赛季软组织损伤率还有其他几个上升趋势（例如，腘绳肌损伤[87例对114例；P = ．085]）；然而，这些未达到统计学显著性。
结论
本研究表明，与2019年相比，在2020年受COVID - 19影响的NFL常规赛期间总受伤人数显著增加。由于COVID - 19取消2020年季前赛后，2019年至2020年有几种主要软组织损伤的增加达到统计学显著性。这些发现表明，有组织的球队季前训练和体能训练可能对预防最高水平的运动相关损伤有作用。
