Morphological and functional features and the level of physical development of girls of youthful age of the Republic Mordovia

Students belong to a group of high health risks, since during this period of development, young people are under the influence of the inevitable processes of active physiological restructuring of the body and intensive socialization of the individual. The purpose of the study is the anthropometric indicators and indices of physical development of 1648 girls aged 17-21 of the Republic Mordovia. Anthropometric measurements included the determination of the following parameters: body weight, standing and sitting body length, circumference of the chest, shoulder, forearm, wrist, thigh, abdomen, buttocks, lower leg, ankles. The comprehensive research program was designed in such a way that it was possible to calculate body surface areas, weight and height values, body strength indices and body proportionality indices. It was found that in the studied population, girls have a wide face, a narrow long nose, and a medium-sized skull. The majority of the population is characterized by the absence of excess body weight. Girls have a normosthenic type of constitution, have an average level of physical development, an average level of body density. Among female students, a mesomorphic type of physique is common with proportional body development, a normal proportion of the bone component and a slightly increased proportion of fat and muscle components. The inversion and dysplasia of sexual dimorphism revealed in the course of the study may be a response of a more labile female body to the negative influences of social and environmental factors.
