ИЗМЕНЧИВОСТЬ МОРФОФУНКЦИОНАЛЬНЫХ ПОКАЗАТЕЛЕЙ СТУДЕНТОВ Г. КРАСНОЯРСКА В ЗАВИСИМОСТИ ОТ СОМАТОТИПА

Abstract

This paper presents a definition of the variability of morphometric parameters of first and second year students of three major universities of the city of Krasnoyarsk, depending on the type of constitution. The study of somatometric indicators is important for determining physical development and general health. The study covered 765 students aged 18 to 20 years (393 girls and 372 boys). Somatometry was carried out according to V.V. Bunak’s methodology, adopted at the Moscow State University Research Institute of Anthropology in the morning with a standard set of tools. The following anthropometric parameters were measured: body length, body weight, girth, anterior-posterior and transverse diameters of the chest. The type of constitution was determined using the Ries-Eysenck index. The hand strength of the right and left hands was measured using a medical electronic manual dynamometer DMER-120-0.5, as well as the index of hand strength as a percentage. In females, the predominant type of constitution according to the Ries-Eysenck index was asthenic, with 57.0 %; in males, the normosthenic type dominated at 45.5 %. The gender heterochrony of the values of the median anthropometric indicators in adolescence, depending on the somatotype, was revealed. Morphometric parameters of body length, girth, transverse and antero-posterior chest diameters, and absolute indicators of carpal dynamometry gradually increase from asthenic to picnical type of constitution, both in boys and girls. The body length is maximal in asthenic somatotype in all subjects. The index of wrist strength is maximum in girls of the asthenic type of constitution and in boys of the normosthenic type, the minimum is in all students of the picnical somatotype. The correlation of absolute values of dynamometry and body weight was determined in all subjects. A moderately pronounced positive relationship was revealed between the values of the index of the wrist strength of the right hand and the chest girth, while the Spearman index in girls is 0.4 (p<0.05), in boys – 0.39 (p<0.05).
