Abstract
Aim of this study is to analyze gender peculiarities of physiological and psychophysical basis of students’ academic activity.
 Materials and Methods. 32 medical students (16 men and 16 women, 19-22 years) were examined. Students were proposed an alternative method of a colloquium on normal physiology in the form of a computer test. The test consisted of 30 questions, time of testing was not limited. The test was considered to be done if the number of correct answers was 50% or more. Examination of students’ heart rhythm, hemodynamic, and psychological parameters was conducted before and immediately after the test. Cardio-intervalogram was recorded within 5 minutes using Varicard hardware-software complex. The Students t-test, Mann-Whitney analysis, Wilcoxon analysis were used to determine the significance of differences between parameters among and within groups of men and women. Relationships of the studied parameters were determined using Spearman’s method of rank correlation.
 Results. It was demonstrated that fulfilment of the test by men was associated with reduction of hemodynamic parameters, with reduction of parasympathetic component and activation of sympathetic suprasegmental and central mechanisms of regulation of heart rhythm. Women showed stability of hemodynamic parameters and increase in suprasegmental influences on the dynamics of heart rhythm with lower average values. In correlation analysis conjugated pairs were found with the two components being different psychophysiological and physiological parameters, time and effectiveness of fulfilment of the test. The total number of conjugated and stable parameters were higher in women than in men both before and after computer testing.
 Conclusions. Gender peculiarities of hemodynamic basis of academic activity of students were found. The described dynamics can be considered a manifestation of a higher stability and relatively lower mobility of regulatory mechanisms in women.

Summary
ФГAОУ ВО Первый Московский государственный медицинский университет им. И.М. Исследование вариабельности сердечного ритма, гемодинамических показателей и психофизиологических характеристик студентов проводилось перед и сразу после выполнения компьютерного контрольного теста. У девушек при меньших средних значениях отмечена стабильность гемодинамических показателей и усиление надсегментарных влияний на динамику сердечного ритма. It was demonstrated that fulfilment of the test by men was associated with reduction of hemodynamic parameters, with reduction of parasympathetic component and activation of sympathetic suprasegmental and central mechanisms of regulation of heart rhythm. Цель – выявление особенностей динамики физиологических и психофизических показателей при выполнении компьютерного зачетного тестового задания юношами и девушками. Материалы и методы Проведенная работа включала в себя сравнительный анализ психофизиологических, гемодинамических и кардиоинтервальных показателей студентов-медиков (16 юношей и 16 девушек в возрасте от 19 до 22 лет) в процессе выполнения зачетного компьютерного теста по курсу нормальной физиологии.
