Physiological indices of taekwondokas are considered in case of a sensory conflict. A group of 18 male taekwondokas aged 18-20 years was subject to physiological studies, including tests of the average latent simple visual-motor response time and resting heart rate. The findings showed that in case of borderline functional states the change in the lability of nervous processes in the central nervous system leads to slowing down of the control effects of the autonomic nervous system on the heart and blood vessels, which causes, depending on the magnitude of changes in the lability of the nervous processes, either very slow heart rate reaction (HR), or a paradoxical reaction (heart rate fall). Based on the latent simple visual-motor reaction time rating in a sensory conflict situation, the initially homogeneous contingent can be divided into separate groups by resistance to sensory conflicts. The individual coefficient of time variation of a simple sensorimotor reaction when moving on an unstable support serves as a criterion of instability in sensory conflicts, as well as energy demand and complexity of integration of central and autonomic mechanisms.
