    Purpose. To select recommendations on the use of physical culture means for students of future teachers, it is necessary to identify their functional features and genetically determined properties of the nervous system. Purpose: to reveal the relationship between the performance of the nervous system, orthostatic test and professional specialization of students of pedagogical universities. Material and methods. Students from 9 different faculties of Ukraine's leading pedagogical institute took part in the study. The total number of subjects was 841 people. Soon the reactions were determined by the program "Psychodiagnostics". Vegetative regulation of vascular tone were determined by the results of heart rate different between in the in the standing position and supine position. An analysis of variance (ANOVA) using the Duncan method was then conducted to determine the influence of the faculty of education on the testing indicators.. A correlation analysis of testing indicators and ranks of faculties was carried out using the Tau-b Kendall method. Results. Students of all experimental faculties were divided into 4 groups according to the number of errors in the choice reaction test based on the results of variance analysis (Duncan method). Faculties were divided into ranks from the first to the fourth. A significant negative correlation of the rank of the faculty according to the indicator of the strength and speed of nervous processes with the heart rate in the standing position (p<0.05) and the difference between the heart rate in the standing and lying positions (p<0.01) was revealed. Conclusions. The results obtained are new in identifying differences in psychophysiological functions and orthostatic reactions among students of pedagogical universities of different faculties; also on the fact of the presence of a correlation between the rank of the faculty in terms of stability and strength of the nervous system of students and the features of their psychophysiological functions and orthostatic reactions. The new facts obtained in this study are the distribution of students into 4 groups according to the stability and strength of the nervous system (from the lowest values to the highest): group 1 - students of the faculties of primary and preschool education, group 2 - students of humanitarian faculties, group 3 - students of the faculty Arts, group 4 - students of the Faculty of Physical Culture and Sports. Also new is the fact of revealing a significant negative correlation between indicators of mobility (reaction rate) and the stability of the nervous system (the number of errors when performing a reaction rate test) in students of pedagogical universities. It is expedient to use physical exercises in accordance with the professional characteristics and personal inclinations of students, who were divided into 4 groups according to the indicators of reaction speed and orthostatic test.
