The Function of Maintaining Body Balance in Students Involved in Various Sports

Abstract

The vital activity of any organism is inevitably associated with the impact of many negative environmental factors on it that can impair its function. Eachreaction of the body to influence from the outside is accompanied by a specific reaction of its vegetative structures and muscles, contributing to the maintenance of homeostasis. Successful sports performance requires an impeccable ability to maintain body balance for a long time. Doing different types of sports, to varying degrees, develops the function of maintaining body balance in trainees. This is especially noticeable in case of shoulder girdle muscular fatigue, even as a result of short intense physical activity. For athletes in various sports, there have long been differences in ensuring that the body maintenancebalance in space after short muscular loads. The statokinetic stability of basketball players and gymnasts is higher than that of tennis players. This was indicated by the lower dynamics of their stabilographic characteristics after a power load, which characterizes the maintenance of body balance. People with low physical fitness are much inferior to athletes in their ability to maintain body balance in space. This is due to the fact that untrained individuals have weak mechanisms for restraining the onset of fatigue. In addition, they have small functional reserves of the organs of autonomic support of life, which additionally weakens the statokinetic stability.

Physiological Properties of Platelets in Dutch Calves during the Dairy Phase

“…This was ensured by a low amount of activated platelets in the blood of the examined calves, including those that entered the process of aggregation (Santa-Rosa et al, 2018;Zavalishina, 2018g). This moment confirmed the decrease in the sensitivity of platelet receptors in young purebreds of the Dutch breed to small amounts of substances in their blood -stimulators of platelet aggregation (Oshurkova & Medvedev, 2018b;Zavalishina et al, 2021). Initially found in calves, the low ability of platelets to aggregate provided their very moderate intravascular activity, which further declined during the observation period.…”
