Physiological Dynamics of the Rheological Properties of Erythrocytes in Young Men Involved In Swimming

Abstract

The parameters of erythrocytes largely determine the processes of blood movement through small vessels and metabolism in tissues. The study included 37 young men who during the past life showed low muscle activity and, at their own request, started regular swimming lessons 3 times a week. The control group consisted of 42 young men who, before being included in the study, went in for swimming for at least 5 years at least 3 times a week. Traditional hematological, biochemical and statistical research methods were used. Weakly physically trained young men before the start of swimming had an increased amount of altered forms of erythrocytes in the blood, which negatively affected their microcirculation. After six months of swimming in the blood of young men, the level of arachidonic acid derivatives normalized, the content of cholesterol molecules and acyl hydroperoxides in erythrocytes decreased, and phospholipids increased in their membranes. In the blood of swimmers, the number of discoid erythrocytes increased and the number of erythrocytes with an altered shape decreased. The control group, which had a long experience in swimming, was characterized by a high preservation of the shape of erythrocytes and an optimum of biochemical parameters taken into account. By the end of the observation, the novice swimmers showed the output of erythrocyte and biochemical parameters to the level of the control group.
