Abstract

This paper assessed the energy, sensorimotor, and information components of the functional status of vehicle operators of sensorimotor profile in high Tian Shan mountains (2800 and 3800 m above the sea level). We surveyed 72 heavy vehicle operators aged 25–40 years with at least 2 years’ working experience in the mountains and at least 5 years’ total working experience. In the process of adaptation, they were divided into 2 groups: with high and low operational and functional levels. The operators’ functional status and the importance of the above components were evaluated using the psychophysiological complex PFK-01, gas analyzer Spirolit-2, and psychophysiological tests (filling in forms) to assess the subjects’ cognitive qualities. During the research, we found that the energy work cost is growing with the mountain environment becoming harsher. What is more, its values are significantly higher in the group with low operational and functional properties. Subjects with high operational qualities showed better visual and spatial abilities and more stable performance of formal tasks. Operators from this group had relatively stable parameters of attention, memory, and thinking, as well as greater ability to process logical information. They were able to build models of response more accurately and generate adequate action strategies. The second group had limited memory storage and low productivity of mental operation. In general, the work outcome of operators of sensorimotor profile in high altitudes depended on the contribution of and interaction between the functional status components.

Keywords
