Air quality in an air ventilated fitness center reopening for pilot study during COVID-19 pandemic lockdown

Abstract During COVID-19 lockdowns less people were able to fulfill the WHO recommendations on physical activity. Also, fitness centers were associated to SARS-CoV-2 superspreader events. However, the risk of infection can be strongly reduced by outdoor air ventilation. To investigate whether a reopening of fitness centers can be justified, concentration was measured during four days in a fitness center. Except for one room, the observed concentrations were mainly under 800 ppm, which stands for high air quality. The strong decrease of concentration during the 15 min evacuations following each hour of workout, speaks for the functionality of the ventilation system. In particular, the number of people present in the studio has a strong impact on the estimated value. In a linear mixed model, an additional concentration of 2.24 ppm (95 % confidence interval [2.04, 2.43]) was estimated for this setting with a total volume of 4065 m in the fitness center and a possible air change rate per hour up to 10. This means, that for 45 visitors, 100 ppm can be added to the predicted concentration. To summarize, a combination of ventilation, restriction of the number of visitors and surveying the concentration allowing for further restrictions in case of need, seems to be an adequate means to reduce the risk of SARS-CoV-2 infection in fitness centers.
Highlights Real world data was observed measuring air quality in a fitness center with restrictions due to the COVID-19 pandemic with a special focus to air ventilation. Except for one room, the concentration was mainly under 800 ppm, which stands for high air quality. During predefined breaks, the concentration strongly decreased, showing the functionality of the ventilation system. The number of visitors in the fitness center has a strong impact on the estimated concentration.
