[The mechanism of force generation in muscles].

The mechanism of sliding force generation under contraction in striated muscle is proposed. The basis of the supposed mechanism is electromechanical effect in cross-bridges and actin filaments, which consists in exciting bending and torsional mechanical vibrations in those structures when the electrical charges flow through them. A quantitative estimation of the generated force is given. The models of the muscle contraction founded on the proposed mechanism are considered and discussed.
