The possible molecular mechanism of the nonlinearity muscle contraction and its experimental substantiation

D. N. Nozdrenko, A. N. Shut, Yu. I. Prylutskyy

A study of the contracting processes of changing in the length and force of muscle fiber is carry ouied under the modulated electrical stimulation in the dependence of physiological solution temperature. The revealed nonlinear effects of muscle contraction are explained within the framework of molecular mechanism proposed.

Key words: muscle fibre, electrical stimulation, nonlinear character of contraction, molecular mechanisms, temperature, isotonic process.
