The article presents the results of the use of fitness programs to optimize the functional state of the body, adaptation and health of high school girls 16-17 years old, experiencing fatigue from training loads.

The research is devoted to psychophysiological regularities of the adaptation of the spatial-temporal functions in the athletes of equestrian sport with the specialization "dressage." Particularly, we evaluate the developmental impact on sensory perception and motor orientation in the spatial-temporal continuum of the special dressage exercise complex. The obtained data confirm the significance of the athletes' space-time characteristics for the effectiveness of sports activities aimed at increasing their preparedness for competitive activity in equestrian sports, because their development leads to an increase in the adaptive capabilities of athletes, helps to optimize the processes in the central nervous system, as well as the vegetative regulation of the functional systems in the body. The development of the horsemen' space-time functions (under control with the help of computer diagnostics of their indicators) can be recommended as an indispensable component of increasing the readiness for competitive activity in equestrian sport.
