REGIONAL FEATURES OF THE MORPHOFUNCTIONAL DEVELOPMENT OF STUDENTS OF KAZAKH NATIONALITY
Aim. To study the features of the morphofunctional development of the Kazakh nationals of the first year of the M. Kozybaev North Kazakhstan State University arrived for training from the northern and southern regions of Kazakhstan with the goal of developing preventive measures to reduce the adaptive stress to university education. Material and methods. The study involved 400 first-year students 17-18 years old, of both genders, studying at different faculties of the M. Kozybaev North Kazakhstan State University (200 girls and 200 boys) who arrived from the northern and southern regions of the republic. Standard methods of determining anthropometric and functional indices, estimating the adaptive potential and the level of physical health were used. The resulting material is processed by the methods of ANOVA statistical methods. Results. Indices of physical development (length, body weight, chest circumference, Quetelet, Pinje and stenius indices) were shown to be within the age-gender norms, but a comparative assessment of physical health of students showed significant differences in the anthropometric and physiological state depending on the previous area of residence. Thus, the length of growth in northerners was higher than that of southerners. The indices of body weight, chest circumference, and the Quetelet index are higher in representatives of the southern regions. By the type of body build, among the girls and boys hypersthenics predominated in the southern region, normostenics - in the northern region. At the same time, with an increase in the constitution, the absolute and relative values of force indices and the vital index increased. At the same time, students in the southern region had a lower functional reserve of the heart, determined by the magnitude of the double product, the heart rate, and blood pressure. For students of the northerners of both genders, satisfactory adaptation (1st “level of health”) is typical, whereas representatives of the Southern Region had a lower level of adaptive potential, which corresponded to the state of exertion of adaptation mechanisms. Conclusion. Comparative evaluation of morpho-functional indices of the body of students of adolescence revealed features of body size, type of constitution, functional reserves of the cardiorespiratory system depending on the previous region of residence. The data obtained can be used to compile standards for the physical development of young people of different regions of the republic and the development of health programs to reduce adaptive stress.
