Some psychophysiological parameters and heart rate variability in young males depending on their individual and typological characteristics

Aim: the paper aims to identify some psychophysiological parameters and HRV in young males depending on their individual and typological characteristics. Materials and methods. The study involved 50 second-year male students of the Tver State Medical University. The Eysenck personality questionnaire, the Spielberger state trait anxiety inventory (adopted by Khanin), and the well-being activity mood (WAM) method were used (NS-Psychotest computer system). Simple and complex visual motor responses were assessed using the UPFT-1/30 portable device (Psychophysiologist). Cardiac intervals were recorded with the CAD-03 system. The data obtained were processed using the Statistica 6.1 software. Results. The average level of neuroticism, situational and personal anxiety was found among male students. Anxiety levels were significantly higher among introverts compared to extroverts. The results of WAM ranged from average to high in different groups. The normotonic type of cardiac regulation was found in all subjects. In introverts, complex visual motor responses demonstrated a shift of vegetative balance towards the dominance of the sympathetic system. Conclusion. Personal and situational anxiety levels were found to be higher in introverts. No significant differences were found between extroverts, ambiverts, and introverts with respect to other psychophysiological data obtained with the WAM method and visual motor response tests. All subjects were in good condition and worked actively demonstrating the same performance and response time. The CVMR test affected the cardiovascular system of the subjects and resulted in intergroup changes in a number of cardiac interval parameters.
