Влияние многосуставных мышц на целенаправленное движение человека

Abstract

The equations ofpurposeful movement of the person who is carrying out exercises on sports shells, possessing elastic properties in the working part, are deduced without taking into account functionalities of muscular system of the person. Actually, the realization of the physical dependences which described by models of movement and have been not reflected in the equations, depends on human anatomy. So various groups of muscles participate in operated movement: one- articulate, two-articulate and multiarticulate. It is shown as at drawing up of the equation of purposeful movement operating forces of two-articulate and multiarticulate muscles are resulted in joints through which they are thrown. Classification of chances of occurrence of forces in multiarticulate muscles, and also work of muscles of antagonists and their influence on distribution of the moments of operating forces concerning Joints is lead. On examples of the analysis of technics of sports exercises in gymnastics it is drawn a conclusion on realization by muscular and nervous systems of each concrete equation ofpurposeful movement by the various ways depending on a condition of the sportsman, his physical and technical training, etc.
