ANATOMICAL AND FUNCTIONAL CHARACTERISTICS OF THE LEVEL OF PHYSICAL DEVELOPMENT AND THE COMPONENT COMPOSITION OF THE BODY OF STUDENTS IN MORDOVIA REPUBLIC OF YOUTHFUL AGE

Abstract

The study of the basic laws of the formation of students' physical health is of great importance for the state not only as an economic, but also as a labor and defense potential of the country. The study of age dynamics is necessary also for the development of regional standards of physical development, physical fitness of population of young people, as well as for improving the system of health-saving technologies in the organization and conduct of the educational process in educational institutions. The aim of the study was to study the level of physical development and body composition of 1612 young men aged 17-21 living in the Republic of Mordovia. In the course of the work, 48 absolute anthropometric indicators were analyzed, characterizing the anatomical and functional characteristics of an individual. It was found that among young people a normosthenic type of constitution with a proportional chest, with a medium-sized head and andromorph body type is widespread. In the population of student’s males, the prevalence of persons with an average level of physical development, an average value of the vital index is characteristic, however, the strength index of the hand in most of the studied had an indicator below normal. The majority of students showed a normal body mass index with an average level of body density, with an increased relative mass of fat and muscle components and a reduced mass of the bone component, which is possibly a consequence of the body's response to the negative influences of environmental factors, as well as reduced motor activity and insufficient physical activity.
