Due to the health benefits of exercise, recommendations were made for lockdown restrictions. Within the CoCo-Fakt study (Cologne-Corona counselling and support for index and contacts during the quarantine period), we aimed to determine how these recommendations were implemented, especially by individuals who were officially quarantined due to an infected persons (IPs) or as close contacts (CPs), and how this affected their physical and psychological condition.Methods From 12 December 2020 to 6 January 2021, all IPs and CPs registered by Cologne’s public health department up to the survey period were surveyed online. Of 10 547 people in the CoCo-Fakt sample, 8102 were integrated into the current analysis. In addition to demographic data, information regarding COVID-19-specific and persistent symptoms or conditions and their association with the amount and type of exercise and screen time before and during the quarantine were collected.Results Before quarantine, 66.9% of IPs and 69% of CPs were physically active; during quarantine, this decreased by 49.4% in IPs depending on the course of the disease and by 30.6% in CPs. Physically active IPs and CPs felt less exhausted and more fit during their quarantine periods than those who were inactive, with active IPs significantly less likely to report prolonged physical and psychological symptoms than their more sedentary counterparts.Conclusion Given the acute and long-term positive effects of exercise on quarantined individuals, corresponding recommendations should be communicated to those affected, especially CPs. Recommendations for IPs depend on their health status.Data are available on reasonable request.
