The aim of the research is to discover how psychophysical self-regulation training influences person's psychophysiological functions. The knowledge is essential to create psychophysiological safety. Two groups of university students consisting of young men aged 19-21 were studied. The first group (experimental group) included young men who had been regularly trained according to relaxation psychophysical regulation system for 1-2 years; the second group (control group) included students who did not practice psychophysical self-regulation. The relaxation program of psychophysical regulation (PPR) developed by Mrs. T. Popova is based on psychophysical exercises (PPE) aimed to teach learners to attain rapid and deep body relaxation, and to train self-regulation of emotions and behavior. Electroencephalography, recording of psychomotor actions and heart performance, psychological testing of anxiety and psychoemotional state were used to analyze psychophysiological functions. The research results showed that after psychophysical self-regulation there is a reduction in the heartbeat rate, blood pressure, anxiety, functional tension, as well as improvement of mood and general state, normalization of electroencephalography results, feeling of calmness and relaxation, and tolerance to a different opinion. All psychomotor parameters for the experimental group were higher than for the control group, which proves a beneficial influence of relaxation exercises on nerve functions. It has been concluded that it is prerequisite to train psychophysical self-regulation techniques to students as the fundamentals of psychophysiological safety and adequate social behavior.

Aim. The article deals with establishing psychophysiological features in overweight women to develop a set of measures for weight decrease and psychocorrection. Materials and methods. We studied two groups of women who were willing to participate in the study: the first groupmean age 54.2 ± 3.0; the second group -mean age 25.0 ± 1.7. The average BMI of the first group corresponded with obesity values (32.3 ± 1.6), while an average BMI of the second group was within the upper limit of reference values (23.7 ± 0.9). However, according to body composition data, there was a risk of BMI increase. As far as the percentage of adipose tissue exceeded the recommended values, recommended weight loss was 18.2 ± 2.6 kg for the older group and 5.6 ± 1.4 kg for the young group. Two groups of women of the same age with normal weight were examined as control groups. Results of the study revealed both age-related and psychophysiological features in women of different weight. EEG analysis showed that alpha rhythm amplitude in women from the first group was higher on average and frequency was lower compared to the second group. In the experimental group, we also revealed a higher level of delta activity in the frontal region at rest. The study of a psychoemotional status revealed that all participants hardly coped with stress. However, young participants overcame stress more easily compared to the older group. Anxiety assessment showed increased values of anxiety. In all participants, personal anxiety was almost at the same level within 48 points. Situational anxiety was higher in young women (51.2 ± 1.3 and 49.6 ± 2.1 points, respectively). Conclusion. The most psychophysiological indicators identified functional stress, particularly in overweight older women. To preserve the optimal psychophysiological status of persons participating in weight correction programs, it is also necessary to correct a psychophysical status in accordance with age-related features.

Aim. The article aims to assess the psychophysiological characteristics of skilled athletes in combat sports (boxing, freestyle wrestling, judo). Materials and methods. 18–23-year-old skilled combat athletes were examined. All athletes were divided into the following groups: the first group - female athletes (n = 15); the second group - male athletes (n = 17); the third and fourth groups - control groups consisted of males and females of the same age and not involved in sports (15 people each). The following methods were used: a pulse measurement, psychological tests, self-assessment of the psychoemotional status, electroencephalography, cardiointervalography with the calculation of statistical indicators of heart rate. Examinations were performed before and after the relaxation exercise, which was a three-minute concentration of attention at a specific point on the body. Results. The results revealed that female athletes had lower indicators of psychoemotional status than males but higher than untrained females. The indicators of psychoemotional stress were lower in female athletes than in male athletes and untrained women. For example, the indicator of personal anxiety in female athletes was 41.0 ± 1.8 versus 47.2 ± 2.5 in untrained women (P < 0.05). In female athletes, heart rate, the amplitude of the mode and voltage index (77.15 ± 2.05) in the structure of heart rate were slightly higher than in males (73.10 ± ± 1.07), which indicated greater functional stress of the heart. Relaxation led to favorable changes in EEG indicators and decreased functional stress of the heart in all subjects. Conclusion. It is recommended to extend the terms of sports training in female combat athletes to ensure a smooth transition to sports specialization and reduce injuries.
