Binnensporten tijdens de COVID-19-pandemie: analyse met behulp van data uit de COVID RADAR app

Indoor sporting locations have been forced to stay closed longer than outdoor sporting locations during the lockdowns introduced during the COVID-19 pandemic. This research addresses the question whether exercising indoors does raise one’s risk of infection with SARS-CoV‑2. This analysis was performed using data from the COVID RADAR app and accounted for user differences in age, vaccine status, sex, other risky behavior, SARS-CoV‑2 prevalence and quality of living environment. Analyzing data from 1,353 users, 13.1% of which reported a positive SARS-CoV‑2 test, we found that exercising indoors leads to an odds ratio of 1.8 with a positive SARS-CoV‑2 test (95%-confidence interval 1.2–2.6, p = 0.003), as compared to users who exercise outdoors. This confirms the justification used in longer closing indoor sporting locations to reduce the number of infections.
