title: [Mathematical model of the mechanical properties of skeletal muscle fibres taking into account compliance of the actin filaments].
abstract: A mathematical model describing mechanical transients induced by the step length changes in skeletal muscle fibres is suggested. The model takes into account compliance of actin filaments and the cross-bridge mechanics. Two different approaches were used for modeling of the cross-bridges: the Huxley-Simmons (1971) model and a new nonlinear viscoelasic model. From a comparison of the results of computer simulation with experimental data we conclude that the best fitting is achieved by using a combined model where both Huxley-Simmons mechanism and cross-bridges viscoelastisity are represented.
