The global pandemic caused by COVID-19 has had far-reaching implications for the world of professional sports. The National Basketball Association (NBA) suspended active regular season play in 2020 after a player tested positive for SARS-CoV-2. No previous studies have examined the impact of COVID-19 on return to play in the NBA.
PURPOSE/HYPOTHESIS: The purpose of this study was to examine performance measures for NBA players who had recovered from COVID-19 and returned to play in the NBA bubble. We hypothesized that these athletes would play fewer minutes and have decreased performance statistics compared with performance during the 2019-2020 regular season prior to the lockdown and with career averages.
Case series; Level of evidence, 4.
NBA players positive for SARS-CoV-2 who played in both the 2019-2020 regular season and the NBA bubble were identified. Data collected included player demographics and player performance statistics.
A total of 20 players were included in the study. Players who had recovered from COVID-19 played significantly fewer minutes per game in the NBA bubble (25.8 vs 28.7; = .04) and made fewer field goals per game (4.6 vs 5.4; = .02) compared with the season prior to shutdown. While NBA bubble players demonstrated slight decreases in averages for points ( = .06), rebounds ( =.13), assists ( = .23), steals ( = .30), and blocks ( = .71) per game, these were not statistically significant. Aside from an increase in made free throws per game during the bubble (3.3 vs 2.8; = .04), player performance was not significantly different from career averages.
For players who tested positive for SARS-CoV-2 prior to playing in the NBA bubble, the current study demonstrated that despite playing significantly fewer minutes per game, performance was not statistically different from either their pre-COVID 2019-2020 level of play or from their career averages.
由新冠病毒（COVID-19）引发的全球大流行对职业体育界产生了深远影响。2020年，一名球员的严重急性呼吸综合征冠状病毒2（SARS-CoV-2）检测呈阳性后，美国职业篮球联赛（NBA）暂停了常规赛。此前尚无研究探讨COVID-19对NBA球员复出比赛的影响。
目的/假设：本研究的目的是检验从COVID-19中康复并重返NBA复赛园区比赛的球员的表现指标。我们假设，与2019-2020赛季停摆前的常规赛表现以及职业生涯平均水平相比，这些运动员上场时间会减少，表现数据会下降。
病例系列；证据等级，4级。
确定在2019-2020赛季常规赛和NBA复赛园区都有上场比赛的SARS-CoV-2检测呈阳性的NBA球员。收集的数据包括球员人口统计学信息和球员表现统计数据。
本研究共纳入20名球员。与停摆前的赛季相比，从COVID-19中康复的球员在NBA复赛园区的场均上场时间显著减少（25.8分钟对28.7分钟；P = 0.04），场均投篮命中数也更少（4.6次对5.4次；P = 0.02）。虽然NBA复赛园区的球员场均得分（P = 0.06）、篮板（P = 0.13）、助攻（P = 0.23）、抢断（P = 0.30）和盖帽（P = 0.71）略有下降，但这些差异均无统计学意义。除了复赛园区期间场均罚球命中数有所增加（3.3次对2.8次；P = 0.04）外，球员表现与职业生涯平均水平无显著差异。
对于在参加NBA复赛园区比赛前SARS-CoV-2检测呈阳性的球员，本研究表明，尽管他们的场均上场时间显著减少，但表现与COVID-19之前的2019-2赛季水平或职业生涯平均水平相比，在统计学上并无差异。
