[Biochemical mechanisms of muscle contraction regulation].
This review is the analysis of molecular mechanisms regulating the contraction activity of voluntary muscles. It summarises the data on muscle biochemistry for last decades. Literary and the author's data are devoted to the analysis of the following problems: ionic gradients of skeletal muscles; the energy origin for processes of the contraction initiation; the biochemical basis of electromechanical coupling; the role of a number of biologically active compounds in muscle functioning; regulatory aspects of the energetic supply of a contraction function; the change of muscle properties under the fatigue. The data given make possible to describe a single contraction cycle on the molecular level.
