Abstract
Student air traffic (AT) controllers were examined to investigate cardiovascular responses to job-specific workload in the air traffic control simulator and to cold-and-hypoxic exposure (CHE). Activation of the parasympathetic nervous system (PNS) during work was an unfavorable factor, yet the CHE-induced increase in parasympathetic activation caused functional improvement. Highly reactive subjects with quick CHE-induced responses (l < 10 s) demonstrated a low performance and a higher PNS activation during work. Reactive subjects (10 < l < 32 s) demonstrated a higher performance, and it took them less time to recover. The CHE-induced response may be regarded as a criterion for assessing individual cardiovascular responses to job-specific workload, which may be used for preparing recommendations on a subject’s suitability for AT control work.
