Air quality analyses were conducted in sports facilities at the Silesian University of Technologyin Poland, with specific focus on training rooms occupied by students. The study aimed to assessthe impact of indoor air quality (IAQ) on human health, taking into consideration variousventilation methods and the number of individuals exercising indoors. Air samples were collectedfrom five training rooms in three sports facilities. The results indicate that outdoor air primarilyinfluences air quality in sports facilities. Internal factors, such as the number of students, floorsurfaces and mattresses, influenced pollutant concentrations (CO2 and PM2.5). Overall, CO2 levelsremained within safe limits, but fluctuations occurred due to physical activity, reaching as high as1859.7 ppm. The average median concentration of indoor PM2.5 was 16.7 μg/m, while outdoorlevels averaged 12.2 μg/m. A correlation between indoor and outdoor PM2.5 pollution underscoresthe importance of using air purifiers to enhance air quality in sports halls.
