title: [Physiological basics of sport activity of professional football players].
abstract: Maintenance of motor activity by autonomic nervous system is adjusted, mainly, by congenital reflexes. But alongside with inborn reactions to muscular work at formation of motor skill the specific vegetative components are formed to the given kind of sport activity.  The aim of our research was revealing those physiological features which are characteristic for an organism of the high skilled sportsmen, with large experience of training and competitive activity.  At tested football players have been measured some parameters of external respiration and cardiovascular system.  In our investigation it is shown, that programming of the same productivity of work and the same effect are achieved by unequal vegetative support and a different combination of separate components of the general vegetative reaction. Definition and a due estimation of these intermediate parameters in conditions of rest and at physical loading enables objective judgement about a functional condition of the sportsman, about weak parts in system of maintenance of a homeostasis of an organism and directions of accomplish the functioning of the basic effectors.
