Influence of Motor Activity Level on the Resistance of Students' Erythrocytes Membranes

Abstract

The problem of reducing the motor activity of young students in the conditions of the modern educational process is more relevant than ever in connection with the trend towards a decrease in the quality of youth health. The purpose of this research was to study the influence of physical activity level of Pedagogical University female students on the resistance properties of erythrocytes. Methods for studying osmotic and peroxide resistance of erythrocytes and catalase activity were used. The background values of osmotic, peroxide resistance in the test groups did not have a significant difference, although the resistance of erythrocyte membranes to peroxide radicals is somewhat more pronounced in the group of girls with conditionally low activity. In the group of girls with reduced motor activity, the level of activity of the catalase enzyme was slightly lower than that in the blood of girls involved in physical exercises. There were no obvious differences in the resistance characteristics of the erythrocyte membrane in the groups of female students with different levels of motor activity at rest. The use of the step test revealed a difference in the structural and functional state of erythrocyte membranes - during exercise, a decrease in the osmotic and peroxide resistance of the erythrocyte membranes of girls from the group with conditionally low motor activity was shown, and a more stable structural and functional state of erythrocytes of girls from the group with a regime of high motor activity . There were no changes in catalase activity against the background of the step test in groups of girls with different levels of motor regimen.
