Blood fluidity during physical exertion of various types

Abstract

This paper presents data from the literature and own results on the study of blood fluidity (or rheological properties) when performing physical exercises. It is shown that the rheology of blood depends on the functional state of the haemostasis system. It has been established that in the physiological state of the organism, physical exertion of any strength can lead to changes in the reactions of primary and plasma haemostasis and, accordingly, the rheological properties of blood. The review describes the study of factors related to blood flow in humans and animals before and after physical exercise (running, swimming, etc.) in the normal physiological state of the organism, with overstrain and with certain types of pathology (cardiovascular and metabolic diseases). Data on blood flow in conditions of physical activity restriction are presented. Special attention is paid to the corrective role of physical exercises on the rheology (fluidity) of blood in violation of homeostasis of the organism. Possible mechanisms of action of physical exertion on blood flow are considered.
