2020年3月11日，由于2019冠状病毒（COVID-19）爆发，美国国家篮球协会（NBA）在约64场比赛后暂停了本赛季，仅在约5个月后恢复，前22支球队在佛罗里达奥兰多被隔离在一起（称为“泡沫”），各打8场比赛作为常规赛的结束。这次重新开始，没有新的旅行队，提供了一个自然的实验，旅行和主场优势的影响，可以系统地检查。我们在这里显示，在2019冠状病毒病前的常规赛中，跨时区旅行会降低胜率、球队投篮准确率和失误率，而一般来说，旅行会减少进攻篮板，增加对手（主队）的得分。此外，我们证明，在没有球队旅行（重新启动泡沫）的情况下，竞争会减少旅行和主场优势对胜率，投篮命中率和篮板的典型影响。因此，职业篮球的主场优势似乎与客队投篮准确性受损有关（即，运动精度）和反弹，这可能分别受到昼夜节律中断或旅行的一般影响，因为当团队在多个时区内或跨多个时区旅行时，这些差异表现得不同。
On March 11th, 2020, the National Basketball Association (NBA) paused its season after ~ 64 games due to the Coronavirus 2019 (COVID-19) outbreak, only to resume ~ 5 months later with the top 22 teams isolated together (known as the “bubble”) in Orlando, Florida to play eight games each as an end to the regular season. This restart, with no new travel by teams, provided a natural experiment whereby the impact of travel and home-court advantage could be systematically examined. We show here that in the pre-COVID-19 regular season, traveling across time zones reduces winning percentage, team shooting accuracy, and turnover percentage, whereas traveling in general reduces offensive rebounding and increases the number of points the opposing (home) team scores. Moreover, we demonstrate that competition in a scenario where no teams travel (restart bubble) reduces the typical effects of travel and home-court advantage on winning percentage, shooting accuracy, and rebounding. Thus, home-court advantage in professional basketball appears to be linked with the away team’s impaired shooting accuracy (i.e., movement precision) and rebounding, which may be separately influenced by either circadian disruption or the general effect of travel, as these differences manifest differently when teams travel within or across multiple time zones.
