The comparative results of the scan of the spine athletes

Studied in a three-dimensional image of the vertebral column characteristics of the projection of the body (frontal and sagittal, horizontal) in cyclic sports of both sexes (running on the middle distance, diving, cross-country skiing, orienteering, speed skating). Every kind of sports lays imprint on the locomotor system, a longitudinal asymmetry of specific nature, makes unique demands on technology sport and specialization in it depending on the total body size, sex, ethnic peculiarities. The data obtained allow to sports teacher make timely adjustments to the original position (rack), vary dynamic and temporal characteristics of the loads. Biological mechanics of sport in its development requires the involvement of new technologies. We hope that these researches will make a new contribution to the resolution of this problem. Sports results in cyclic sports is determined by the long distance, the external force, the metabolic capacity and coefficient of mechanical efficiency. The latter determined by the energy of elastic strain of muscles of the legs in the knee joint in the phase of depreciation, increase in the mean acceleration of the phase of repulsion, increase of amplitude of the vertical oscillation of the center of mass of the body, for the cycle, decrease time support. In addition to strength and time repulsions an important place takes the step length in the sport performance, which depends on the mobility of the hip joint.
