THE IMPACT OF HEAVY PHYSICAL EXERTION ON THE HUMAN BODY

Early sports specialization, intensification of training, increasing the frequency and intensity of competitions, the use of new, non-traditional means of training - these are typical features of modern sports, which significantly increased the requirements imposed on the body of professional and amateur athletes in such conditions, led to an increase in the importance of medical and pedagogical control in the process of sports improvement. This leads to the study of the effect of training with a heavy load on the body of people involved in sports. The purpose of the study is to analyze the effect of heavy physical exertion on the human body. This study was conducted in January 2022. The articles in Scopus were compiled using a combination of keywords related to muscle strength and training with heavy loads. The search was limited to articles published in peer-reviewed journals from December 1, 2000 to December 2020, since the above excerpt presents a wide variety of points of view on the topic of the impact of physical activity on a person. No restrictions were applied to research projects eligible for inclusion. Initially, a total of 725 studies on this topic were identified in the Scopus electronic database. Subsequently, we removed 593 studies that did not meet the inclusion criteria or were duplicates. A total of 31 full-text articles were evaluated for compliance with the requirements. In addition, a search was conducted for the literature included in the literature list of these studies in order to obtain and add more relevant literature. Of the 1,188 articles from the list of references, 1,178 were removed after checking the titles and annotations, as well as a full-text review. As a result, a total of 30 articles meeting the selection criteria were included in this review. The study touches upon the problem of interpretation of the concept of muscle strength in modern sports and its role in the formation of training with heavy physical exertion on the training day of professional athletes and amateurs. The paper also reflects the impact of such types of training on cognitive development, including in conditions of conducting for a long period of time.
