GRAVITATIONAL TRAINING IS A NEW POSSIBILITY FOR THE IMPROVEMENT OF HUMAN MOVEMENT FUNCTION

Abstract

The motional function of a man is ancient and the result of phylogenesis under the influence of the earth's gravitational field. Constant, relative, neuromotor and mass-inertial proportions of the elements of the motional system were formed during the evolution process. During the contemporary stage of human development practically all characters of human locomotions are regulated by parameters of gravitational interactions with the environment [1,2]. Modifications of the coordination structure of human motion were simulated under different conditions of gravitational interaction. The characters of supporting responses, articular angles, accelerations of several body's links and other parameters were measured. The simulation of corresponding conditions of gravitational interactions was achieved by direct modification of human body mass geometry, using the placement of additional weights on the body segments. Results indicate that modification of gravitational interactions on the natural limits resulted in vectors which maintained the coordination structure of complex motional skills. At the same time it was determined that the modification resulted in interactions which caused additional force momenta on the link segments. This did not allow the specific muscles to adapt to the external factors. The coordination system of complex human motions adjusted due to this mechanism. In the author's opinion, the results of this investigation are significant for the training of sportsmen, operators and cosmonauts.
