摘要
目的：研究NBA联赛中高水平篮球运动员感染COVID-19前后比赛成绩的变化：从官方数据库中收集了 NBA 联盟中 68 名球员（19 名前锋、29 名后卫、20 名中锋；平均年龄为 27.14 ± 3.65 岁）在感染 COVID-19 前后 10 场比赛中的运动统计数据。我们使用 Kruskal-Wallis 方差分析来研究 COVID-19 造成的影响：在所有 68 名球员中，与感染 COVID-19 前相比，正负值（Z = -2.392，p = 0.017）和罚球命中率（FT% Z = -2.153，p = 0.031）出现了统计学意义上的显著下降。在内线球员中，我们发现罚球命中率 FT% (Z = 2.674, p = 0.021)、正负值 (Z = -2.371, p = 0.018)出现了统计学意义上的显著下降。在中锋和前锋中，没有统计学意义上的显著变化：结论：COVID-19 对球员疲劳、心肺功能和肌肉耐力的影响可能是导致表现下降的原因之一，同时也不应忽视因隔离而导致的非训练影响。
Will the COVID-19 infection affect the performance of top basketball players? A data-driven analysis.
Purpose: To investigate the changes in the game performance of high-level basketball players in NBA league before and after the COVID-19 infection.
Methods: Athletic statistics were collected from official database for 68 players (19 forwards, 29 guards, 20 centers; mean age 27.14 ± 3.65 years) in the NBA league for 10 games before and after infection with COVID-19. We used a the Kruskal-Wallis analysis of variance to examine the impact caused by COVID-19.
Results: Among all 68 players, a statistically significant decrease in plus/minus (Z = -2.392, p = 0.017) and free throw shooting (FT% Z = -2.153, p = 0.031), occurred compared to the pre-infection with COVID-19. Among the interior players, we found a statistically significant decrease in free throw shooting FT% (Z = 2.674, p = 0.021), Plus/Minus (Z = -2.371, p = 0.018). Among centers and forwards, there was no statistically significant change.
Conclusion: The impact of COVID-19 on players' fatigue and cardiorespiratory and muscular endurance may have contributed to the decline in performance, and the impact of detraining due to isolation should not be ignored.
