A variety of factors influence the performance of schoolchildren. The main factors are psycho-emotional stress and systematic physical activity that requires a constant tension of body's regulatory systems aimed at mobilizing the functional body reserves. The analysis of blood pressure enables to estimate quantitative and qualitative changes in the regulation of the cardiovascular system. The combination of the Stroop test and the monitoring of the cardiovascular system make it possible to assess not only attention and cognitive function parameters, but the phases of the stress response of regulatory systems as well. The purpose of the study was to analyze the relationship between stress factor and the functional state of adolescent cardiovascular system. In the context of stress factor (Stroop test), the circulatory system of students gets activated, and its indicators vary differently among boys and girls. At rest, girls have the lowest performance of the circulatory system. Before the test, heart rates vary in boys and girls in different ways. In the course of our study, we have found out a direct relationship between heart rate, blood pressure before and after psycho-emotional load that testifies the predominance of the sympathoadrenal system activity. We have revealed the arterial hypertension is determined by physiological and social factors. Prevention of arterial hypertension in existing standards of schools requires reconsidering and improving of educational approaches, especially in terms of physical education.
