[Statistics on actin globule chains, stretched by hydrogen bonds, and the Hill law in quantum mechanics theory of muscle contraction].
The process of sarcomere membranes approaching under the action of actin and myosin filament stretching is studied theoretically. In elaboration of previous studies it is supposed that this stretching is due to the formation of hydrogen bonds excited by the energy of ATP splitting. A possibility for the hydrogen bond breakage at different stages of contraction is considered to be the greater the more are the polymers stretched, and the larger statistical scatter in the moments of H-bonds formation at different filaments if it is supposed that sarcomere contraction occurs much slower than stretching of each separate filament. As a result, one obtains a relationship between the rate of contraction and the external force which is close to the Hill's law, and the external force efficiency of a muscle contraction and heat extraction value are related to parameters of polymers and their properties.
