| Popis: | This study aims to compare carbon dioxide (CO2) concentration levels measured in fitness centers with the applicable guidelines from Brazil, France, and Europe. Three fitness centers in Florianopolis, Santa Catarina State, Brazil (fitness centers A, B, and C) participated in this study. The fitness centers have different physical characteristics and ventilation systems. Fitness centers A and B have split ventilation systems, while fitness center C has a central ventilation system. The air quality was assessed by determining the CO2 concentration level, as measured by a non-dispersive infrared CO2 concentration sensor. Data was analyzed with descriptive and inferential statistics. All three fitness centers recorded CO2 concentrations significantly above (p = 0.00) the maximum level of 750 ppm recommended by the European standard. Fitness centers A (= 3752.13 ppm) and C (= 1360.89 ppm) also had CO2 concentrations significantly above (p = 0.00) the maximum level of 1000 ppm recommended by the Brazilian and French guidelines. CO2 concentrations in fitness centers were significantly above the maximum permitted levels. Besides suggesting inefficient ventilation in these fitness centers, high CO2 concentrations can impair indoor air quality and increase risks to the health of practitioners. |
