Abstract
Recently, there has been a significant growth in the number of athletic facilities associated with the progressive demand of people trying to reverse the increasingly sedentary lifestyle of current society. Cross-training facilities have become more popular in recent years among these training centers. Therefore, a detailed investigation of their indoor air quality (IAQ) is required to ensure a healthy environment for their occupants. In this study, we evaluated the IAQ of a cross-training facility in San Antonio, Texas, USA, for four days in January 2022. Each day was associated with a different air ventilation scenario involving the use of ceiling fans and an air filtration unit during the training sessions. Data from carbon dioxide (CO2) and particulate matter (PM) concentrations have been gathered for 24 h in 5-min intervals for high-intensity physical activity, such as cross-training workouts, and subsequently analyzed. CO2 concentration has been used to obtain both the infiltration rate of the building using the tracer gas decay method, and the CO2 generation rate, providing reference values as a function of the occupancy for different workout sessions. The applied methodology can be used to calculate the required volumetric fresh air flow rate to ensure a healthy environment regarding CO2 concentration in athletic facilities. In particular, the fresh air necessary rates obtained for the cross-training sessions are higher than the ones associated with sedentary activities. Finally, the deposition rate of PM from 0.3 to 10 mu m has been calculated, including those potentially harmful to humans, namely PM2.5, PM5, and PM10.
