THE FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM OF HIGH SCHOOL STUDENTS UNDER THE INFLUENCE OF TRAINING LOADS ^{[№ 3 ' 2017]}
The problem of preserving the health of the young generation and a significant decrease in its level in recent years, determines the need for monitoring the functional state of a growing organism. The cardiovascular system is the leading system, it causes the functional state of the organism as a whole. The intensification of a training load, especially for high school students may condition the tension in the functioning of a heart and blood vessels and reduce the adaptation reserves of an organism. Therefore, for effective prevention of violations in the state of health of school-leavers it is necessary to monitor the reactions of a cardiovascular system to a training load. A study of the functional state of a cardiovascular system of high school students under the influence of training loads was carried out. The study showed that systolic, diastolic, and average arterial pressure in young men is higher than that of girls, and regardless of gender it exceeds the average norm for children of this age. For young men of the town of Ishim, Tyumen region, systolic and minute blood volumes are lower for than their peers living in the North region. In the dynamics of a school week fluctuations in systolic blood pressure in seniors are expressed to a greater extent than diastolic. The level of systolic blood pressure in girls by the end of a week regularly increased, in young men the level of systolic pressure in a school week dynamics practically did not change. In the dynamics of a school day in boys and girls fluctuations in diastolic blood pressure were more significant. Increase in diastolic blood pressure after classes at senior pupils was the higher, the greater the number and difficulty of lessons were. These study results indicate the voltage of a functional state of a cardiovascular system at high school students under the influence of training loads.
