In order to study the functional state of the cardiovascular system, a study of the main indicators of the circulatory system of young students at the fifth grade in Tuvan Republican boarding school (Kyzyl) and Secondary School No. 2 (Kyzyl) was conducted. It is shown that the average value of heart rate, blood pressure, systolic blood volume, minute blood volume indicators of fifth-graders of both educational organizations did not exceed the age norms. Evaluation of vegetative regulation by the Kerdo index showed a predominance of schoolchildren with vagotonia regardless of gender. In schoolchildren, regardless of the type of training, the predominance of parasympathetic influence in the regulation of hemodynamics, which may indicate the presence of fatigue during the training period of students, was revealed.
