title: [The interrelation of mechanisms regulating postural stability and voluntary precise movement in athletes].
abstract: Interrelation mechanisms of body systems under common and complicated conditions for regulation of different postures and of voluntary precise motion were studied during the tests on athlete-shooters. It was demonstrated that during fatigue development under complicated conditions postural stability worsened, mechanisms of its correction aimed to improve stability at the moment of shot activated, activity and interrelations between the somatic and vegetative systems increased, precision of shooting decreased, which demonstrated intensification of integration of both physiological (motor and vegetative) and functional (postures and precise motion) systems. It is concluded that interrelation mechanisms of two functional systems are determined by complexity of the stabilized posture, participation of both the inborn and formed regulatory programs in its regulation, structure and character of regulation of the voluntary action performed, and are realized at different levels of the CNS and manifested both via parameters of a final adjusting result of every system and via parameters of physiological systems by entering components into functional ones.
