Статическая работоспособность и особенности функционального реагирования на мышечную нагрузку юношей разных соматотипов

Abstract

The aim of the research is to study the strength characteristics and type of functional response to muscle load of young men of different somatotypes, depending on physical fitness. The study involved 128 practically healthy young men aged 18 to 23 years. The group of subjects included qualified athletes, swimmers, as well as healthy young men engaged in physical culture within the framework of the university program. Somatotype was assessed in all subjects using Hit-Carter method, arm strength and static endurance – according to Rosenblat method, and the type of functional response with Kaznacheev method. It was found that young men of the endomorphic somatotype were characterized by a strong physique, a larger amount of skin-fat folds, low values of the muscle index, less endurance of the hands and did not demonstrate a distinct preference for the type of functional response. The young men of the ectomorphic somatotype had a less robust physique, a smaller thickness of the skin-fat folds, greater endurance of the hands and gravitated to the stayer type of functional response of the neuromuscular apparatus. The young men of the mesomorphic type significantly differed from representatives of other somatotypes by greater arm strength, sprinting type of functional response and, according to other morphofunctional indicators, occupied an intermediate position between endo- and ectomorphs. The analysis revealed functional connections between the components of meso- and ectomorphy, maximum static muscular endurance and types of functional response. The revealed significant differences and interrelations between the morphofunctional parameters under consideration and the types of functional response indicated the phenotypic features of individual development characteristic for each somatotype group. The obtained data should be taken into account when choosing the specifics of physical culture and sports activities.
