Electrophysiological studies mechanism of movements precision athletes

We consider features precision control nelokomotornymi movements with emphasis on the accuracy of the joints as a procedural phenomenon, combining components: accuracy of measuring the articular angle, reproduction and differentiation. The main result is that found no unique relationship between the frequency-amplitude characteristics "Turnov" EMG anterior deltoid hands and goniometric indices of precision measuring and reproduction. Found explicit similarities in the dynamics of changes in the characteristics of EMG and statistics describing the accuracy of differentiation of the brachial articular angle. As a consequence of the established facts discussed that the precision movements are the result of simultaneous administration of separate components of the articular accuracy.
