Summary. The purpose of the study is to identify the age-related features of psychophysiological adaptation at the physiological, psychophysiological, and mental levels in workers performing particularly demanding tasks in the Far North.
Materials and methods. Men < 40 years old (14 people, (33.4±3.2)) and men > 40 years old (10 people, (45.1±3.9)) were compared. At the physiological level, PFA was assessed using the heart rate variability (HRV) method. At the psychophysiological level, it was assessed using visual-motor tests (VMT). At the mental level, it was assessed using the self-assessment scale (SAS) and the differential diagnosis of reduced work capacity (DRC). The functional activity of the central nervous system was assessed using EEG, visual analysis, and indicators of cerebral energy metabolism.
Results of the study. At the physiological level, the tension of the regulatory systems of the autonomic nervous system (ANS) was revealed, to a greater extent in persons > 40 years of age. The tension of the ANS was also evidenced by the EEG data, which revealed signs of dysfunction of the cortical structures and stem formations involved in the formation of emotional reactions and the regulation of autonomic functions.
At the psychophysiological level, persons < 40 years of age demonstrated better performance of functions carried out by the cortical-subcortical pyramidal-striatal level of movement organization. And better performance of functions carried out with the predominant participation of cortical functions – by persons > 40 years.
At the mental level, higher well-being, activity, mood were revealed in persons < 40 years and a greater degree of fatigue in persons < 40 years.
Cerebral energy metabolism in persons < 40 years was higher than in persons > 40 years, which indicated a lower level of PFA in persons < 40 years compared to persons > 40 years. A possible reason for revealing a lower level of adapt.
