title: [Physiological-ergonomic mechanism of the skeletal muscles].
abstract: The article deals with theoretical analysis of present data on physiology of muscular activity. This analysis helped to specify physiologic and ergonomic mechanism of skeletal muscles work. The authors prove this physiologic and ergonomic mechanism to result from known mechanic and chemical processes in muscular tissue structures. Those mechanic and chemical processes underlie well-known molecular theories of muscular contraction. The physiologic and ergonomic mechanism includes change in elasticity basic for mechanic models and theories of muscular work, so this mechanism appears superior to other models and theories explaining muscular activity. Physiologic and ergonomic mechanism of muscular work appeared to be genetically linked with morphologic and functional differentiation of locomotory units, with presence of specific muscular zones different in contraction and tensile strain.
