Abstract

The features of students’ cardiac activity while answering common and complex questions during both the direct answer and rest after the examination are studied. The investigation involves 23 students having sport specialization of handball, basketball, I grade qualification – Sport Master Candidate. The dependence of students’ cardiac activity tension on the complexity of examination question during the examination session is found. The tension of cardiac activity is determined according to haemodynamic parameters (heart rate, blood pressure, systolic volume, minute volume of blood and total peripheral vascular resistance) and P / T index of electrocardiogram. The tension of cardio activity is found to be significantly higher with the answers for complex questions than for common ones. The reliable increase of haemodynamic parameters is observed except for systolic volume being lower than with common questions. Conversely, this parameter is reliably increased at rest after the answers for complex questions. P / T index at answers for common questions is on average 69.7%. Some students have P / T index of 300, 500% at answers for complex questions. Against the background of the complex questions, the  amplitude of the T wave is sharply reduced, and the P wave - significantly increased.
