Some immunophysiological features of sports activity under climatic and geographical conditions of the middle Ob region

Abstract

This paper analyzes the cellular and humoral components of the immune system in athletes who were born, lived, and trained under the conditions of the middle Ob region (Khanty-Mansi Autonomous Okrug—Yugra, KhMAO–Yugra). The main group included young men and women, who were engaged in cross-country skiing (12 men and 10 women) and volleyball (11 men and 10 women). The control group (regional norm) included ten men and ten women, who were born and currently lived in KhMAO–Yugra and did not do any sports on a regular basis. The age of the subjects ranged from 19 to 22 years. It was found that the parameters of cellular and humoral immunity differed slightly with respect to the control group. A significant decrease in the total count of leukocytes, neutrophils, and lymphocytes was observed in men and women, who were born, lived, and trained under the conditions of the middle Ob region; in addition, a decrease in the parameters of humoral immunity (B cells and IgA) was also observed in male skiers. It was found that the total leukocyte count, the level of B cells, and the IgG concentration in men who live in the middle Ob region and do not do any sports is higher than that in women of the same group.
