RESILIENCE AS AN INTEGRAL CHARACTERISTIC OF PERSONALITY AMONG CADETS OF EMERCOM OF RUSSIA

Relevance. Resilience as an integrative resource of an individual, determining its psychological stability was studied among cadets of the Emercom of Russia to develop a psycho correctional program and increase the effectiveness of vocational training and health maintenance.Intention. To develop a model of resilience based on the identification of associated personality manifestations among the cadets of EMERCOM of Russia.Methodology. The study was conducted on the basis of the Far Eastern Fire and Rescue Academy a branch of the St. Petersburg University State Emergency Service Ministry of Emergency Situations among 150 cadets of the faculty of fire safety aged 19–21 years. Psychodiagnostic methods were used as well as psychophysiological rehabilitation complex “REACOR” for biofeedback training and UPFT 1/30 “Psychophysiologist”.Results and their analysis. Parameters of life meaningfulness increase proportionally to resilience. The analysis of terminal values showed that cadets with low resilience sought freedom, financially secure life, pleasures, while cadets with high resilience opted for development, continuous physical and spiritual self improvement. Indicators of internal motivation according to K. Zamfir test were lower in cadets with low and medium resilience vs high resilience. External negative motivation in the group with lower resilience, on the contrary, was higher due to avoidance prevailing over external positive motivation. Adaptation to new or changing conditions is quite complicated for cadets with low resilience and can be disturbed depending on external circumstances. Low resilience was associated with pedantic, anxious, cyclothymic, excitable and dysthymic personality accentuations, medium resilience was associated with cyclothymic and demonstrative accentuations, and high – with hyperthymic and demonstrative accentuations. Cadets with low and medium resilience commonly used confrontational coping strategy. Cadets with low resilience showed increase in flight – avoidance strategies in contrast to those with medium and high resilience (p < 0.05). Low resilience indicates a decrease in tension, the predominance of parasympathetic activity, pronounced inertness and passivity when performing tactical and technical actions. Cadets with high resilience demonstrated improved attention . Average and maximum response time was shorter in cadets with high resilience compared to those with low and medium resilience (p < 0.01), which indicates an increased concentration, activity, and speed. Greater response time in cadets with low resilience probably indicates their passivity and inertness when completing tasks (p < 0.01). After the heat chamber, average and maximum visual motor response time was longer in the group with low and medium resilience (p < 0.05). The structure of resilience includes biological (psychophysiological), social and psychological components. The predictors of resilience are the meaningfulness of life, such coping behaviors as self control, acceptance of responsibility, flight avoidance; personal adaptive potential and its components behavioral regulation and communicative potential; rigid and emotive accentuations; external negative motivation; psychophysiological indicators – vagosympathetic balance (LF / HF), average reaction time.Conclusion. An experimental study of the psychological factors of reactions to professional stressors among cadets made it possible to draw up a scheme of resilience as an integral characteristic of a personality, and to reveal its components.

Evaluation of the effectiveness of single session audiovisual stimulation for the organism functional state’s correction

Based on the analysis of the changes in the bioelectrical activity of the brain, the dynamics of cerebral blood flow and the vegetative balance of the body, the efficacy of a single 15-minute session of audiovisual stimulation for the correction of the functional state of the organism was evaluated. It was found that after the audiovisual stimulation session, the mean value of the alpha-rhythm power in the frontal, anterior-parietal and occipital leads of the right and left hemispheres of the brain was statistically significant more than in the background study. Such a change in the power of the alpha-rhythm reflects the level of ascending activation necessary for the organization of adaptive behavior, and can also characterize the intensity of the neuro-emotional stress. Increasing the power of the α-rhythm indicates a decrease in the level of nonspecific cerebral activation and is one of the main characteristics of the state of functional comfort. Statistically significant ifferences in the indices of powers of the β - and β -rhythms inherent in the state of active wakefulness were determined. The decrease1 2in the power index of the electoencephalography delta rhythm was revealed. The revealed dynamics of cerebral blood flow parameters was subject to pronounced individual differences, which made it impossible to determine the direction of the trend. It was established a gradual decrease in the power of the low-frequency component of the cardiorhythm with simultaneous increase in the contribution power of the high-frequency component, reaching a statistically significant difference at the last stage of registration, which leads to a significant decrease in the coefficient of vagosympathetic balance after the audiovisual stimulation session. The revealed changes indicate a decrease in the tone of the sympathetic part of the autonomic nervous system. Thus, it is established that after a single 15-minute audiovisual stimulation session, the value of the α-rhythm power in the frontal, anterior parietal and occipital leads of the right and left hemispheres of the brain increases, the power indices of the beta and delta rhythms of the electoencephalography decrease, the stress index and the vegetative index decrease balance, and also the coefficient of the vagosympathetic balance of the rhythmocardiogram. These changes characterize the optimization of the functional state of the organism and contribute to an accelerated restoration of working capacity.

Exercise stress - criteria fitness athlete

The article described a common statistical processing of information from the human body, as insufficiently correct, the necessity of evaluation functions organiz-ma, its adaptation reserves - with the help of the system analysis. The aim of the study was the use-tion of new products on the basis of multivariate phase space of states. Two CHECK dennyh research unit in 2 groups of students studied parameters of tremor using bioizme-nary complex with no load and load, as well as the recorded heart rate cut-ny, calculated indicators of activity of the sympathetic and parasympathetic divisions of the autonomic nervous system, the standard deviation intervals, Baevsky stress index. We calculated the components of the spectral power in the low and ultralow- frequency bands, as well as the value of vagosympathetic balance. After the standardized dynamic loading (30 squats) registration continued for 5 minutes. Using innovative methods proved to be more sensitive to the identification of the elements studied. The regularities in the dynamics of the behavior of the state vector of the body of persons trained and untrained should be used to quantify the degree of detraining of the body, as well as to assess the quality of the dose of physical activity (exercise) in athletes under relevant preparations (including sports).

Tone-entropy analysis on cardiac recovery after dynamic exercise

Oida, Eiichi, Toshio Moritani, and Yukio Yamori.Tone-entropy analysis on cardiac recovery after dynamic exercise. J. Appl. Physiol. 82(6): 1794–1801, 1997.—Autonomic controls on heart rate variability have been investigated; however, sympathovagal interactive modulations remain unexplored. The purpose of this study is to present a new method, tone-entropy analysis (T-E analysis) of heart period fluctuations, and to make clear an intensive cooperation of autonomic networks in heart recovery. On the basis of evidence obtained in animal experiments, we hypothesized that heart periods are lengthened or shortened beat to beat by assumed physiological mediators: accelerator and inhibitor. Their operations were evaluated through a normalized successive variation of the period, that is, the percentage index (PI). The process was described through PI distributions by using two indexes, tone and entropy, standard values of which were obtained through pharmacological autonomic blockade experiment. T-E analysis was applied to heart recovery (70 min) after dynamic exercise by 12 female athletes. Interactive autonomic modulations were expressed by a curved path in tone-entropy space. Results suggested that heart rate decay proceeds not by withdrawal of one pathway but by increasing activity of both pathways as vagosympathetic balance inclines slightly but significantly to the vagus division in the course of recovery. The process was examined through Fourier spectral analysis as well.
