Abstract

In the present paper we study the spatial distribution of non-invasive electromyographic signals on the front surface of a human hand arm during movement in the elbow joint. We describe experimental work and mathematical processing of registered signals massive. Statistical processing of signals from the biceps showed that the excitation in muscle tissue with similar movements such as ballistic contraction spreads through the muscle, mostly in a linear fashion. However, there is a random component, which, as expected, is associated with the mechanisms of physiological resistance to muscle fatigue. The hypothesis is confirmed by the increase in the level of the random component for the trained subjects (athletes).
