Paper presents the research of muscle nonlinear stiffness characteristics dependence on the loading duration. The nonlinear differential equation of nonlinear biotronic subsystem of muscle has been derived. Analyzing mentioned expression by numerical methods it was determined that there are three main dominant frequencies in the frequentative characteristics of the muscle and values of them and amplitudes of oscillations decline as the load time becomes longer. Comparison of analytical research results to experimental ones has shown that their regularities are nearly related.
