Physiological basis of the improvement of movement accuracy on the basis of stabilographic training with biological feedback

Physiological parameters of hitting the ball in the unsupported position and prospects for improving spikes through training with a biological feedback were studied in volleyball players. The physiological and biomechanical parameters characterizing a direct attacking shot in a supported position correlate with the biomechanical specificities characterizing the performance of this short in a jump. At the same time, the physiological ability to provide the accuracy of hitting actions is associated, first, with improving the coordination of trunk and arm movements in the flight phase, second, with the factors of intramuscular and intermuscular coordination of the striking arm, and, third, with a change in the pattern of motions of an athlete’s center of pressure. The use of a computer-based stabilographic method of training with a biofeedback contributes to the optimization of physiological and biomechanical parameters of motor actions in the unsupported position, which results in an increased accuracy of hitting the ball in a jump. The obtained results open prospects for applying the method of computer-based stabilography for improving the performance skill of accuracy- and target-oriented actions in unsupported positions in various kinds of sports.
