title: [Dynamic model of the regulation of muscle fiber contraction].
abstract: The model is based on assumption of the dependence of membranes' electrical excitability on the muscle length and developed strength. The model, with its parameters being interconnected by means of differential equations, includes the idea of "the absolute length of muscle" with points along the 0-1 scale. From this standpoint, different types of muscle fibers differ in the position of the physiological working range on the length scale as every point on this scale has its own respective interrelationships between rlastic and viscous parameters and its own regularity of transformation of the stimulus into characteristics of development of the force of contraction. Characteristics of contractions inherent to different types of muscles including muscle fibers of the heart, have been reproduced in the model.
