Conducted studies of the functional state of cerebral and central hemodynamics in children (30 boys, 25 girls) 12-13 years in diving. Aim of this study was to investigate the adaptation of the cardiovascular system and cerebral circulation in children to scuba diving in a closed water. Studies were conducted using the method reoencephalography, pulsotonometrii. It is shown that the water to dive diving at the beginning and end of the course the basic values diving reographic indicators (the boys -Alpha 2, Av/Aa, DIC, DIA and defense, the girls - Q_x, Alpha 2, Av/A, DIC, DIA and defense) corresponded physiological age norm. Found that after a single submerged under water diving a significant decrease of RI boys in the front-mastoidalnyh leads both cerebral hemispheres, the girls in the front-mastoidalnyh and oktsipito-mastoidalnyh leads both cerebral hemispheres. These changes may indicate a decrease in blood supply to the brain vessels in boys in the basins of the internal carotid arteries, the girls in the basins of the internal carotid and vertebral-basilar arteries. Results of the study REG indicators at the end of course children after diving scuba diving showed that RI in fronto-mastoidalnyh leads both hemispheres in children was significantly (P<0.05) decreased, indicating a decrease in blood supply to the brain vessels in children in swimming pools internal carotid arteries. Also found that, after scuba diving at the beginning and end of the course diving of teens there is a decrease in heart rate and pulse pressure, systolic and diastolic blood pressure.
