The Physiological Reaction of the Surface Properties of Erythrocyte Membranes in Individuals who Previously Had Low Physical Activity at the Beginning of Regular Physical Training

Abstract

Context: The rheological parameters of red blood cells largely determine the processes of microcirculation
and metabolism in all tissues. Assessing their characteristics in people with low physical activity, who
began to regularly experience moderate physical activity, can help to more fully reveal the mechanisms for
optimizing the micro-rheological properties of red blood cells. The observation group consisted of 45 men
of the second adulthood, who began regular classes in the athletics section 3 times a week, who previously
had low physical activity. The control group consisted of 42 men of the same age who regularly visited the
athletics section 3 times a week for at least 10 years. Biochemical, hematological and statistical research
method were applied. For 6 months of physical training, people who previously had low physical activity
noted the elimination of the imbalance of arachidonic acid metabolites, lowering cholesterol and acyl
hydroperoxides with an increase in their total phospholipids. After 6 months, these individuals showed an
increase in red blood cells-discocytes by 8.2% with a decrease in the number of reversibly and irreversibly
altered forms of red blood cells by 18.5% and 2.1 times, respectively. It is clear that for people of the
second adulthood, who began regular physical activity after a long period of low physical activity, a gradual
improvement in the cytoarchitectonic properties of red blood cells is characteristic, which improved their
microcirculation processes and activated metabolism.
