Dynamics of indicators of the functional state of the body and cytomorphological changes in wrestlers during the performance at the championship of Ukraine in Ukrainian belt wrestling

Abstract

The issue of the functional state of the body of Ukrainian belt wrestlers is poorly studied. There are isolated research data on the improvement of the functional state of the body of wrestlers as a result of training. Studying the issues of the functional state of the body of wrestlers of various types of wrestling is extremely important, as it determines the athlete's success during competitions and the growth of skill during many years of sports training. The purpose of this work was to determine the physiological features of the response of the body of Ukrainian belt wrestlers during the Championship of Ukraine on April 29, 2023.
 As a result of the research, we established that in the pre-start period, the indicators of the cardiovascular system and respiratory system functioning of all examined wrestlers correspond to the physiological state of pre-start readiness of the athlete's body with a predominance of sympathetic vegetative influences. The functional indicators of the wrestlers after the termination of the performance at the Championship of Ukraine for Ukrainian belt wrestling differ depending on the number of matches they have held and the intensity of the physical load. The winner of the competition, having held 4 winning matches without a break between them, was subjected to physical stress at the level of submaximal power. The winners, who played a smaller number of matches with breaks in between, managed to restore the functional state of the cardiovascular system and respiratory system without experiencing such a load. The functional indicators of wrestlers who lost matches and stopped participating in competitions indicate an insufficient functional reserve of the cardiovascular system and respiratory system. The changes in the cytomorphological indicators of the buccal epithelium that we obtained indicate a significant strain on the body's functional systems, signs of dehydration in the winner who played four matches. In other athletes, there are certain signs of discomfort and strain on the body's functional systems (cytolysis, karyolysis, karyorrhexis, the presence of binucleated cells and leukocytes).
