MOVEMENT ACTIVITY AND HEALTH OF THE CARDIOVASCULAR SYSTEM

Abstract

The beneficial effect of physical exercises as a health (treatment) tool has been proven by many studies and is beyond doubt. At the same time, discussions among scientists about the amount of motor activity, the intensity of exercises, the expediency of using this or that type of physical activity in terms of the impact on human health in general and, especially, the cardiovascular system as one of the main links of the body, which determine health, quality and life expectancy. After all, the results of several scientific studies provide contradictory data on these issues. For example, the statement that sports activities destroy health and reduce life expectancy has become debatable. The purpose of our research is to form an idea about the optimal amount, intensity, and specificity (types) of physical activity to ensure the health of the cardiovascular system and long active longevity. Some experts suggest that reaching extreme levels of fitness using intense exercise can trigger cardiovascular disease and increase the risk of sudden death. At the same time, some data showed a gradual decrease in mortality depending on the increase in cardiorespiratory efficiency but did not reveal its upper threshold, after which the risks would begin to increase. In other words, the authors of these studies found no evidence of harm associated with extreme levels of physical fitness. Thus, for the average person in an industrial society, the problem of an insufficient level of physical activity becomes more relevant than not an excessive one. One of the key issues in the context of the health of the cardiovascular system is the specifics of the impact of physical exercises of different orientations. Researchers are trying to better understand the extent to which aerobic fitness and muscle strength are involved in promoting cardiovascular health mediators.
