New method for loaded muscle's stiffness evaluation

Abstract

Paper presents the new method of muscle nonlinear stiffness characteristics' evaluation according to the loading duration. Stiffness characteristics of muscle's biosystem, are analysed assuming that it elongates according to a constant velocity. Presented analytical expressions enable to estimate the variation of dynamical characteristics in muscle biosystem not only during loading but also at the primary stage in the beginning of it. It was noticed, that in the beginning of loading, stiffness of the muscle has fully determined and real values.
