Localized outbreaks of COVID-19 have been reported in sporting facilities. This study used the Agent-based Modeling (ABM) method to analyze the transmission rate of COVID-19 in different sporting models, sporting spaces per capita, and situations of gathering, which contributes to understanding how COVID-19 transmits in sports facilities. The simulation results show that the transmission rate of COVID-19 was higher under the Fixed Movement Route (FMR) than under the Unfixed Movement Route (UMR) in 10 different sporting spaces per capita (1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 m) ( = 0.000). For both FMR and UMR, the larger the sporting space per capita, the lower the virus transmission rate. Additionally, when the sporting space per capita increases from 4 m to 5 m, the virus transmission rate decreases most significantly ( = 0.000). In the FMR model with a per capita sporting space of 5 m, minimizing gathering (no more than three people) could significantly slow down the transmission rate of the COVID-19 virus ( < 0.05). This study concluded that: (1) The UMR model is suggested in training facilities or playing grounds; (2) The sporting space should be non-overcrowding, and it is recommended that the sporting space per capita in the sporting grounds should not be less than 5 m; (3) It is important to maintain safe social distancing and minimize gathering (no more than three people) when exercising.
已在体育场馆报告了 COVID-19 的局部暴发。本研究使用基于代理的建模（ABM）方法分析了不同运动模式、人均运动空间和聚集情况下 COVID-19 的传播率，有助于了解 COVID-19 在体育设施中的传播方式。模拟结果表明，在 10 个人均运动空间（1、2、3、4、5、6、7、8、9 和 10 m）下，固定运动路线（FMR）的 COVID-19 传播率高于非固定运动路线（UMR）（= 0.000）。对于 FMR 和 UMR，人均运动空间越大，病毒传播率越低。此外，当人均运动空间从 4 m 增加到 5 m 时，病毒传播率下降最明显（= 0.000）。在人均运动空间为 5 m 的 FMR 模型中，最大限度地减少聚集（不超过 3 人）可以显著减缓 COVID-19 病毒的传播率（<0.05）。本研究得出结论：（1）建议在培训设施或比赛场地使用 UMR 模型；（2）运动空间不应过度拥挤，建议运动场地人均运动空间不应小于 5 m；（3）保持安全社交距离和最大限度地减少聚集（不超过 3 人）对于运动非常重要。
