Estimating the inhaled dose of pollutants during indoor physical activity.

摘要: Abstract Background It is undeniable that many benefits come from physical activity. People exercise in fitness centers to improve their health and well-being, prevent disease increase attractiveness. However, these facilities join conditions cause poor indoor air quality. Moreover, increased inhalation rates during have influence on inhaled doses of pollution. Objectives This study aims calculate the dose pollutants exercise, by estimating minute ventilation participants measuring pollutant concentrations centers. Methods Firstly, 20 performed an incremental test a treadmill, where heart rate were measured simultaneously develop individual exponential regression equations. Secondly, was classes estimated based calculated coefficients. Finally, using monitoring program 63 classes. Results Estimated higher aerobic than holistic The main difference registered for PM 10 presented average ratio between greater four. Minute were, average, 2.0 times showed heavy demonstrating need maintain high quality Conclusions illustrates importance inclusion data when comparing pollution different population groups. work has first time Also constitutes important contribution assessment future studies be
