Air quality analyses were conducted in sports facilities at the Silesian University of Technology in Poland, with specific focus on training rooms occupied by students. The study aimed to assess the impact of indoor air quality (IAQ) on human health, taking into consideration various ventilation methods and the number of individuals exercising indoors. Air samples were collected from five training rooms in three sports facilities. The results indicate that outdoor air primarily influences air quality in sports facilities. Internal factors, such as the number of students, floor surfaces and mattresses, influenced pollutant concentrations (CO2 and PM2.5). Overall, CO2 levels remained within safe limits, but fluctuations occurred due to physical activity, reaching as high as 1859.7 ppm. The average median concentration of indoor PM2.5 was 16.7 μg/m3, while outdoor levels averaged 12.2 μg/m3. A correlation between indoor and outdoor PM2.5 pollution underscores the importance of using air purifiers to enhance air quality in sports halls.
