Abstract
This model emphasized respiratory responses and incorporated mathematical descriptions of experimental results obtained from exercising humans. Prediction equations for tidal volume, anaerobic threshold, minute volume, respiratory work, and performance time were included, as well as dynamic changes in each. This model can help to design future respirators, aid workers wearing respirators, and regulate occupational health and safety. In general, the current model can predict performance time when subjects exercise both with and without masks. The current model was fitted for 30% and 80% VO2max of experimental data from the Human Performance Laboratory (University of Maryland, College Park). The results showed predicted values were reasonable and closer to the experimental data. Results of physiological values and performance times showed that the model structure was valid and that the model was capable of making rational predictions of the average effects of respirator wear on the pulmonary system during physical activity.
