Comparison of Cardiac Vagal Modulation From the Orthostatic Stress Test Between Untrained Individuals and Athletes

Vegetative regulation of vascular tone and features of the nervous system of pedagogical universities students. Is there a relationship with professional specialization?

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". Orthostatic reactions were determined by the results of heart rate in the supine position and in the standing position. An analysis of variance (ANOVA) was performed using Duncan's method to determine the influence of teaching faculty on test performance. 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. Physical exercises should be applied according to the professional characteristics and personal inclinations of the students, who were divided into 4 groups according to the indicators of reaction speed and orthostatic test. For students of the faculties of primary education and preschool education (1st group), we recommend using mobile and sports games. For students of humanities and natural sciences faculties (2nd group), any physical exercises that require an average manifestation of all physical qualities are suitable: dances, gymnastics, sports games, martial arts. Students of the Faculty of Arts (3rd group) are suitable for physical exercises that require high concentration of attention for a long time, for example, cyclical exercises. We recommend that students of the Faculty of Physical Education and Sports (4th group) continue to improve in their chosen sport, while also studying other sports.

Comparative characteristics of the functional state of future art teachers and other pedagogical specialties students

Purpose: to reveal the autonomic regulation peculiarities of the functional state based on indicators of the nervous and cardiovascular systems work of future fine arts and music teachers for the development of recommendations for the use of physical exercises. Material and methods 812 students of pedagogical institutions of higher education of Ukraine took part in the study. During psychophysiological testing, the following indicators were determined for each test: reaction time, number of errors. The shorter the reaction time, the higher the mobility of nervous processes. The lower the number of errors in the reaction test of choosing two elements out of three, the higher the stability of nervous processes. Orthostatic reactions were determined by the results of heart rate in the lying position and in the standing position. Parametric processing methods (Student's method for comparing average values) and hierarchical cluster analysis were used. Results Two groups of students - future teachers were identified: with a predominance of the sympathetic department of the autonomic nervous system and with a predominance of the parasympathetic department of the autonomic nervous system. The largest number of students with predominance of the parasympathetic department of the autonomic nervous system was found among students – future teachers of creative specialties (faculty of arts). Students of the Faculty of Arts have significantly longer latency time of visual-motor reaction compared to representatives of other faculties. This indicates a lower mobility of nervous processes of students of the Faculty of Arts in comparison with students of other faculties. Along with this, future art teachers have significantly fewer errors in the test for choosing 2 elements out of 3. This indicates greater stability of nervous processes in future teachers – representatives of art compared to other future teachers. Conclusions Students – future teachers of creative specialties (faculty of arts) have the more stability and less mobility nervous system in combination with the autonomic nervous system parasympathetic department predominance. That is why endurance exercises that do not require frequent switching of attention are suitable for them. Such exercises include walking, slow running, swimming et. all. Exercises should be performed for at least one hour. They will also be suitable for exercises with the activation of visual perception.
