پاسخ های تنفسی در هنگام ورزش در دستگاه تنفسی خود در میان آتش نشان ها و آتش نشانان

The present study showed that when compared to controls, firefighters’ hypoventilate during a maximal test and GXT. The hypoventilation resulted in increased ETCO2, and presumably increased arterial CO2, during exertion. It is proposed that firefighters have altered CO2 sensitivity due to voluntary hypoventilation during training and work. Confirmation of low CO2 sensitivity and the consequence of this on performance and long-term health remain to be determined.
