Abstract: | Effects of meridional migrations in shuttle from middle latitudes to regions beyond the Polar Circle, where an expedition and the organization of work shifts were being conducted, were studied. Three main types of systemic reactions of human hemodynamics and hemostasis were established. The first type was characterized by a moderate increase in the arterial blood pressure (BP) at the beginning of the shift with its subsequent normalization; by hypocoagulemia; and by an increase in the total phospholipid content, with a significant increase in the content of lysolecithins (an adaptive type). The second type was characterized by hypertension throughout the whole shift, by hypercoagulemia with significant changes in the phospholipid spectrum, and with a pronounced increase in the lysolecithin and cardiolipin fractions (a hypertensive type). The third type was characterized by a decrease in BP and an increase in heart rate (HR), by hypocoagulemia and an asthenic state associated with sleep disorders, and a decreased mental capacity (an asthenic type). |
