Электрофиэиологический анализ локомоторных движений грудных конечностей некоторых млекопитающих

Abstract

Podography, mechanography of 3 joints and electromyography of the 12 muscles of each of thoracic limbs were performed separately and synchronously for a dog, goat and horse running on the treadbahn with different preset velocities. It was established that run accelleration is accompanied by an increase in frequency of locomotor cycles due to reduction in a phase of support and pace elongation. It is also shown that a combinative functioning of muscles of the given limb is not of antagonistic character. It is a wave, one locomotor cycle long, running throught all the muscles in sequence typical of the given pace and speed. The degree of the given joint functional independence of the other joints of this limb is determined and biomechanical significance of this phenomenon is shown.
