The regular practice of physical activity helps in the prevention and control of several non-communicable diseases. However, evidence on the role of physical activity in mitigating worsening clinical outcomes in people with COVID-19 is still unclear. The aim of this study was to verify whether different levels of physical activity provide protection for clinical outcomes caused by SARS-CoV-2 infection. A cross-sectional study was conducted with 509 adults (43.8 ± 15.71 years; 61.1% female) with a positive diagnosis of COVID-19 residing in Ribeirão Preto, São Paulo, Brazil. Participants were interviewed by telephone to determine the severity of the infection and the physical activity performed. Binary logistic regression was used to indicate the odds ratio (OR) of active people reporting less harmful clinical outcomes from COVID-19. Active people had a lower chance of hospitalization, fewer hospitalization days, less respiratory difficulty and needed less oxygen support. The results suggest that active people, compared to sedentary people, have a lower frequency of hospitalization, length of stay, breathing difficulty and need for oxygen support. These results corroborate the importance of public policies to promote the practice of physical activity, in order to mitigate the severity of the clinical outcomes of COVID-19.
定期进行身体活动有助于预防和控制多种非传染性疾病。然而，关于身体活动在减轻 COVID-19 患者临床恶化结局方面作用的证据尚不清楚。本研究旨在验证不同水平的身体活动是否为 SARS-CoV-2 感染引起的临床结局提供保护。这是一项横断面研究，共纳入 509 名居住在巴西圣保罗里贝朗普雷图的成年人（43.8±15.71 岁；61.1%为女性），他们的 COVID-19 诊断均为阳性。通过电话访谈确定感染严重程度和所进行的身体活动。采用二项逻辑回归来指示活跃人群报告 COVID-19 临床结局较轻的优势比（OR）。活跃人群住院的可能性较低，住院天数较少，呼吸困难较少，对氧气支持的需求较低。结果表明，与久坐不动的人相比，活跃人群的住院频率、住院时间、呼吸困难和对氧气支持的需求较低。这些结果证实了公共政策促进身体活动实践的重要性，以减轻 COVID-19 临床结局的严重程度。
