[The physiological effects of the voluntary control of respiration in children and adolescents].

The information about the peculiarities of the forming the voluntary control of respiration in age aspects is produced in this article. It is shown, that the respiratory tests: voluntary hyperventilation and voluntary breath holding may be the convenient model for researching this problem. The irregular in the ontogenesis forming of the reactions of main physiological systems of the organism on the voluntary hyperventilation is revealed. The phase analysis of the duration of voluntary breath holding showed, that the volitional control of respiration begins to realize at 12 years old. The dynamics of the indexes of cardio-vascular system and CNS indicates of the high reactivity of vegetative nervous system of adolescents and of more distinct alterations in functional state of CNS in children in comparison with adults during voluntary breath holding. The sex distinctions in the mechanism of synchronization the internal rhythmic processes during the voluntary breath holding, especially in adolescents are revealed.
