Features of the influence of working conditions on psychophysiological functions of unmanned aircraft systems operators

This study was conducted to determine the influence and assess the impact of specific factors of working conditions on the psychophysiological functions of Unmanned Aircraft Systems (UAS) operators. The research involved 41 military personnel (men aged 20-35 years old) who operated the I class “Light” UAS and were engaged in a varied range of professional tasks. The aim was to understand the complex impact of these distinct factors on operators during the execution of their duties. To examine their psychophysiological status, we employed modified methods using the PFI-2 hardware/software complex. The following indicators were determined: accuracy of reaction to a moving object, strength of nervous processes, functional mobility of nervous processes, simple visual-motor reaction, complex visual-motor reaction, orientation in space, and visual memory. The role of climatic and microclimatic factors in professional activity was studied using a questionnaire, where their influence on functional status was assessed on a 100-point scale. To facilitate further theoretical development and practical application, we determined the investigated factors integral impact on shaping operators’ subjective perception and specific psychophysiological qualities that are professionally significant for military personnel. The preliminary analysis showed the heterogeneity of feelings the influence of various components of the external environment factor. To correct this heterogeneity, we used the non-linear correction method (logarithmization of analyzed data, when large values of an analyzed parameter could be reduced due to the properties of logarithmic function). Then, a correlation (Spearman correlation coefficient) and regression analysis of studied parameters has been carried out with a preliminary check of the structure of operator perceptions for normality using the Shapiro-Wilk test. As a result, a list of psychophysiological qualities that change under the influence of the external environment factor in individuals with different perceptivity to its components has been selected.

Psychomotor reaction in adolescents with different levels of physical development

The work is aimed at studing dynamics of the latent time of motor reaction in conditions of noise interference in adolescents. The result of research of latent time of impellent reaction and force of nervous processes (under the tepping-test) at teenagers of 13-15 years with a certain level of physical development demonstrated that children with a high physical development level have low functional reserves brain programming systems. The influence of the processes underlying acceleration in terms of adaptive reactions of teenagers is showed by this way. The study of the motor reaction to a light stimulus was carried out using the latent time of simple motor reaction computer program developed in the laboratory. It was clear that the processes of acceleration affected the morph functional organization of regulatory brain systems, reducing their level of adaptability and operational reliability. Low indicators of adolescents’ strength of nervous processes, which were obtained during tapping testing, are the general modern trend towards a decrease in the level of their health. The data obtained can be used in the development of medical and pedagogical methods for correcting the functional state of the body of adolescents at the prenosological stage.

ASSESSMENT OF NERVOUS SYSTEM STRENGTH (BRAIN EFFICIENCY) IN YOUNG TAEKWONDO ATHLETES DURING TRAINING SESSIONS

Introduction. The article explores the dynamics of indicators of nervous system strength (brain efficiency) in young athletes during taekwondo training sessions, taking into account their age and gender characteristics. The relevance and prospects of the research are determined by the relationship between the psychophysiological properties of athletes and their performance in taekwondo competitions, as well as the necessity of considering this relationship in the training process. The research aims to assess the indicators of higher nervous activity (HNA), particularly the strength of nervous processes (brain efficiency), in young taekwondo athletes during training sessions, considering age and gender. Material and methods: general scientific (logical, inductive); analysis of scientific and methodological literature and internet sources; instrumental methods (study of nervous system strength as an indicator of brain efficiency), methods of mathematical data processing. The indicators of nervous system strength (brain efficiency) in young taekwondo athletes were assessed instrumentally using the PND method (M.Makarenko). Results. The dynamics of indicators of higher nervous activity, particularly the strength of nervous processes (brain efficiency), were studied in 34 young taekwondo athletes, taking into account their age and gender characteristics. Measurements were taken during training sessions: in the warm-up phase, the main phase, and the cool-down phase. The test results were systematized, and based on quantitative indicators, corresponding graphs were constructed, followed by analytical evaluation. Conclusions. The research on the dynamics of indicators of nervous system strength (brain efficiency) in young athletes during taekwondo training sessions, considering their age characteristics in two age groups of young taekwondo athletes, revealed that athletes in the older age group (boys aged 13–16 and girls aged 12–15) demonstrate better indicators of brain efficiency (fewer mistakes) compared to the younger group (boys aged 8–12 and girls aged 8–11), presumably due to developmental age characteristics and greater training experience. It was established that at the beginning of training sessions, the results of girls in the younger group outperform the results of boys, while in the older age group, boys' results are higher compared to girls. It was also found that young athletes in both groups demonstrate the best indicators of brain efficiency in the main part of the training session compared to the beginning and the cool-down phase.

Особливості застосування психофізіологічних профілів операторів безпілотних авіаційних комплексів для професійного відбору

In order to develop new approaches to the psychophysiological selection of operators, 219 male servicemen aged 20 to 40 years old with experience in operating unmanned aerial systems of the first class Light and involved in a wide range of professional tasks were examined. To study their psychophysiological status, modified methods were used using the PFI-2 hardware and software complex. The following indicators were determined: accuracy of reaction to a moving object, strength of nervous processes, functional mobility of nervous processes, simple visual-motor reaction, complex visual-motor reaction, orientation in space, and visual memory. To identify a set of informative indicators that can best divide the analyzed group of operators into 3 clusters, a stepwise discriminant analysis was applied. The technique was developed to obtain several psychophysiological profiles of vocational aptitude, equally effective in terms of content. The statistical discrepancy of these profiles has been established. Ways of evaluating the superiority of these profiles have been shown. The principle of “necessary diversity” in the implementation of occupational psychophysiological selection of operators working in conditions with increased danger has been proposed and discussed. A number of advantages of using this principle to increase accuracy and expand the contingent of persons subject to occupational psychophysiological selection have been identified. The technology of graphical presentation of psychophysiological profiles of operators of unmanned aerial complexes was developed for the purpose of assessment of suitability for professional tasks.

Indicators of protein exchange in dogs with different types of higher nervous activity

The relevance of the study is due to the current lack of data on cortical mechanisms of protein metabolism regulation in dogs, which is important to consider when developing methods of corrective action on metabolism. The aim of the study was to determine the peculiarities of protein metabolism in dogs with different types of higher nervous activity, and to establish the relationship between the main characteristics of nervous processes and indicators of protein metabolism in the blood. The leading method in the study of this issue was a new method for determining the typological features of the nervous system in dogs, and the obtained scores of strength, balance, and mobility of nervous processes helped to identify the degree of their influence on protein metabolism. A significant effect of short-term nutritional deprivation on the content of certain indicators of protein metabolism in the blood of dogs, depending on their temperament, was established. Under the action of the stimulus during the day, a decrease in the level of albumin and changes in the ratio of globulins were observed in the blood of dogs, in particular, an increase in the relative content of α- and β-globulins and a decrease in γ-globulins. It was determined that the type of higher nervous activity has a significant effect on the content of total protein, albumin, globulins, β-globulins, γ-globulins and the value of the albumin-globulin ratio (F=3.02-14.6>FU=2.90; P<0.05-0.001) in the blood plasma of dogs. A direct relationship between the strength of nervous processes and the content of total protein and albumin, γ-globulins (r=0.62-0.73; P<0.01) and an inverse relationship between the content of αand β-globulins (r=-0.51-0.56; P<0.01) was found three days after the onset of short-term nutritional deprivation. The balance of nervous processes was inversely related to the content of β-globulins (r=-0.44; P<0.05). The fundamental knowledge gained is of practical value for the development of new, modern methods of metabolic correction taking into account the temperament of animals

Gender-specific issues for sport preparedness of elite female athletes in team sport games

Purpose. The goal of this study was to identify gender-specific issues of sports training to assist in the planning of training and competition loads of female elite athletes in team sport games.
 Material and methods. Bibliometric techniques were applied in this study to gather highly cited papers in sport sciences published during 2005-2022. The method of expert evaluations was used to determine the modern problems of female elite sports. To determine the model characteristics of the optimal psychophysiological state and balance function of elite male versus female athletes during physical exercises, two independent groups 17 women and 24 men were compared, elite athletes from such sport games, as: basketball (women, n=10 and men, n=14), handball (women, n=3 and men, n=5) and volleyball (women, n=4 and men, n=5). Mathematical and statistical processing and data analysis were carried out using the computing and graphic capabilities of the computer programs "Statistica" and Microsoft Excel 2010.
 Results. The analysis of sports scientific literature regarding gender-specific issues and the experts' analytical notes allowed us to obtain information about the main problems, such as: using male models of physical preparation at the training process for women. We determined that the psychophysiological functions for men and women have very particular gender-specific characteristics. For men, it is a predominance of attention, and for women, mobility and strength of nervous processes, respectively. As for the ratio of the quality of the equilibrium function of elite athletes without and with visual control, significantly higher indicators are observed for women (0,98 ± 0,02, p<0,05) compared to the group of men (0,78 ± 0,06, p<0,05).
 Conclusions. The research results obtained by us when comparing the psychophysiological and biomechanical indicators of elite athletes of different gender groups provide reliable information about the need to build different approaches in planning special physical loads for female and male athletes in sport games.

FEATURES OF NEURODYNAMIC AND SENSORIMOTOR REACTIONS IN CHILDREN AGED 5-7 YEARS

Abstract. The study presents the results of research on sensorimotor reactions and neurodynamic indicators in children aged 5-7 years, which serve as a necessary and essential criterion for assessing the psychophysiological development of preschool participants. The aim is to prevent maladaptive disorders and preserve the health of the future generation.
 Objective. To investigate and analyse the dynamics of neurodynamic and sensorimotor response features in children aged 5-7 years. Research Methods and Discussion. The study was conducted with children aged 5-7 years at the educational institution “Primary School — Preschool Educational Establishment” No. 42 in the city of Sumy. To study the age dynamics of neurodynamic and sensorimotor indicators, an instrumental diagnostic method was chosen using the “Diagnos-1M” device. Functional mobility of nervous processes (FMNP), strength of nervous processes (SNP), and balance of nervous processes (BNP) were evaluated. To identify individual characteristics of sensorimotor reactions of different complexity levels, latent periods of simple visual-motor reaction (PZMR), latent periods of choice reaction to one of three (CR 1–3) and two of three (CR 2-3) signals were determined.
 Conclusions: The study revealed that children at the age of 7, in comparison to children aged 5 and 6, have significantly higher indicators in all neurodynamic parameters (SNP, FMNP, BNP) and sensorimotor reactions (PZMR, CR (1–3), CR (2–3)). This may indicate not only the completion of the anatomical structure of the brain but also the morphological and functional development of subcortical structures and the cerebral cortex.

To the characterization of nervous processes in people with different heat sensitivity

The aim of the study was to diagnose functional mobility and strength of nervous processes in people with different heat sensitivity.Materials and methods. For this study, 150 students aged 17-20 years were involved. The subjects were divided into two groups, according to the questionnaire "Levels of heat sensitivity" and heat test. Diagnosing functional mobility of nervous processes in the feedback mode was conducted using the computer program "Diagnost 1M". The strength of nervous processes was also studied, according to the quality of mental load, using the imposed rhythm mode and in the feedback mode. Results. According to the results of the examination, it was found that participants with lower heat sensitivity (group B) have a higher rate of nervous processes strength according to the criterion of the total number of presented and processed signals within five minutes. They also had an average level of functional mobility of nervous processes. Participants with higher heat sensitivity (group A) had a lower than average level of functional mobility. In addition, a correlation was found between the minimum reaction time to a stimulus and the level of heat sensitivity in people. Regarding the quality of mental load performance using the imposed rhythm mode, a higher than average level of test errors was found in group A, while in group B this indicator was within the average level.Conclusions. Persons with lower heat sensitivity have a higher level of strength of nervous processes and their functional mobility, which results in more successful coping with mental load in the mode of imposed rhythm, compared to participants with higher heat sensitivity. Therefore, in subjects with a higher level of heat sensitivity, compared to those with a lower level, impaired concentration and decreased mental performance occur earlier.

Evaluation of the functional state of taekwondo athletes 7-13 years old according to the indicators of the finger-tapping test

Background and Study Aim. The functional state of organs and systems determines the level of preparedness of athletes in modern sports. The evaluation of the state of the central nervous system is of particular importance. The purpose of the study is a comparative analysis of the results of the tapping test of taekwondo athletes of different ages. Material and Methods. 42 taekwondo athletes were divided into groups of 14 people depending on age: group 1 - (7.50±0.14) years, group 2 - (10.07±0.22) years, group 3 - (13.36±0.27) years. Participants of groups 1 and 2 were engaged in the amateur level, and group 3 had a skill level of 2 Gup - 1 Dan. A special computer program for devices with the iOS operating system was used. An Apple tablet was used - iPad, 4th generation with a screen diagonal of 9.7 inches. The finger-tapping test was carried out for 60 s, 12 subtests of 5 s each. For analysis, we evaluated the total number of depressions during the entire test, the average number of depressions per 5 s, the number of depressions in each subtest, the duration of depressions in each subtest, and the dynamic performance index (DPI). Group results were compared using the nonparametric Rosenbaum test (Q) and sign test (z). Results. It was found that the athletes of the 2nd group performed more depressions in the test as a whole and in 11 out of 12 subtests compared with the athletes of the 1st group. Comparison of the middle and senior groups also confirmed the best results of the athletes of the senior group in 6 subtests out of 12. The senior athletes had a longer duration of depressions in 2 subtests. The most pronounced differences were established when comparing the results of the junior and senior groups. A significant excess in the number of depressions was confirmed for senior athletes in all subtests. The duration of depressing was longer in senior athletes in 2 subtests. A significant reduction in the number of depressions from the beginning to the end of the test was determined. Changes in the duration of depressions were opposite, and the time increased from the beginning to the end of the test. Conclusions. The presence of a direct dependence of the results of the finger-tapping test of taekwondo athletes on age is determined. An increase in the number of depressions in the test, an increase in the integral criterion - an indicator of dynamic performance was determined. The results reflect an increase in the strength of nervous processes, positive changes in the functional state under the influence of regular training loads. This condition should be evaluated as a predictor of the success of taekwondo athletes. The computer version of the test is mobile, informative and valid. It can be used in monitoring the functional state of combat sports athletes.

Gender-specific issues of strength training loads planning for elite female athletes

Introduction
 Strength training is a fairly popular topic, both among sports product users and among scientists in Switzerland and other countries around the world. Nevertheless, the analysis of the literature is indicating that there is not enough scientifically based research on gender-specific issues of strength training loads planning for female athletes in sports of higher achievements.
 Purpose
 The goal of this study was to identify gender-specific issues in the planning of strength training loads for elite female athletes based on the psychophysiological and biomechanical methods of controlling.
 Methods
 To determine the model characteristics of the optimal psychophysiological state (indicators of the efficiency of attention, volume of voluntary attention, productivity, coefficients of motivational, volitional and typological components, stress resistance) and balance function of elite male and female athletes during practising competitions, we compared two independent groups (women, n = 17 and men, n = 24). All participants were aware of the objectives of the study and agreed to participate. Mathematical and statistical processing and data analysis were carried out using the computing and graphic capabilities of the computer programs “Statistica” (Statsoft, version 7.0) and Microsoft Excel 2010.
 Results
 The analysed factors and their component indicators to determine the state of psychophysiological functions for women and men. The analysis of the obtained indicators indicates that the manifestation of the characteristics of psychophysiological functions for men and women has its own gender characteristics. For men, it is a predominance of attention, and for women, mobility and strength of nervous processes. As for the quality of the balance function, significantly higher indicators (p < 0,05) are observed for women precisely when performing an attempt with closed eyes.
 Conclusions
 The sexual peculiarities of the formation of psychophysiological functions of elite athletes, the functional peculiarities of psychomotor and mental activity, as well as the peculiarities of the psychophysiological organization of information processing were revealed. The nuances regarding the indicators of quality of the balance function among elite athletes, depending on gender, are revealed, which is primarily related to the location of the centres of gravity: in women, it is located in the hips, and in men, it is much higher. This will, for example, directly affect the difference in the recommended angle in the knee area for female and male athletes during the strength exercise “squat with a barbell”. In addition, we would like to note that the data of the studied literature sources and our previous studies allow us to formulate a hypothesis regarding the change in the speed of basic training in elite female athletes under the influence of hormonal changes in different phases of their menstrual cycle. This hypothesis will be further investigated in forthcoming research.

Особливості психофізіологічного статусу студентів з різними типами вегетативної регуляції в умовах навантаження

The process of students’ adaptation should be considered as a dynamic and integrated process of forming the necessary skills to meet the needs that arise during study at a higher education institution. The purpose of the study was to establish the nature of psychophysiological indicators of students with different types of autonomic regulation in conditions of physical and mental activity. Materials and methods. The article presents the results of a study of the psychophysiological indicators of 128 students (65 boys and 63 girls) of the Petro Mohyla Black Sea National University aged 17-25 years. All students had psychophysiological indicators before and after mental and physical activity measured with the device for psychophysiological research «PFI-2». The students were divided into groups according to the types of vegetative regulation, according to the method of express assessment of the functional state of regulatory systems according to N. I. Shlyk. All students had indicators of heart rate variability at rest on short recordings of the cardiac signal (2 minutes), obtained with the help of the rhythm «MPFI-rhythmograph-1». Proofreading method according to the method of M. V. Krivonosov et al. (2001) was used as a mental load, which consisted of finding and selecting a specific letter in test tables for 20-25 minutes. Aerobic exercise consisted of taking a distance of 2 km on a rowing machine Concept-2 for 10 minutes. Results and discussion. The obtained results showed that after the mental load, the psychophysiological indicators of students of all groups did not change reliably, which led to the formation of adaptation mechanisms. However, only the students of group 3 have grouped reliable changes in some indicators of the correct sample, which reflects the state of development of mobilization. After physical exertion, changes in individual and typological indicators were observed in representatives of groups 1 and 3. A significant decrease in the indicators of functional mobility of nervous processes and the strength of nervous processes indicates the mobilization of the body's reserves. The value of the dynamics of nervous processes in group 1 significantly increased after physical exertion, which indicates the development of a state of fatigue. There was also a significant increase in the number of anticipated/delayed reactions in group 3, which indicates the predominance of excitation processes over inhibition. After physical exertion, no significant changes in psychodynamic parameters were observed, but in group 2, the time of the complex simple visual-motor reaction significantly increased, which indicates the development of a state of fatigue. After physical exercise, the students of group 3 have observed significant changes in the values of the correction test indicators, which indicates the mobilization of the body's reserves. Conclusion. The analysis of the results of the study made it possible to establish that the mental load had an insignificant effect on the representatives of group 3. After physical exertion, significant changes were observed in representatives of all groups, except for group 4

Психофізіологічні характеристики ватерполістів на етапі попередньої базової підготовки

The purpose of the study was to determine the quantitative parameters of the psychophysiological characteristics of water polo players at the stage of preliminary basic training. Materials and methods. 26 water polo players took part in the study at the stage of preliminary basic training. Theoretical analysis and generalization, documentary method, measurement, methods of mathematical statistics were used in the study. Results and discussion. In recent years, the development of high-performance sports has led to an increase in the requirements for the technical and tactical training of highly qualified athletes and the duration of their sports careers, so the issue of finding alternative ways to increase the effectiveness of competitive activities has become urgent. Differentiated approaches to the training of athletes at various stages of long-term training, taking into account the psychophysiological characteristics of athletes, have been successfully implemented in various sports in recent years. Taking into account these trends, the issue of considering the psychophysiological characteristics of athletes when building the training process at various stages of long-term training becomes relevant. In the course of the study, the psychophysiological characteristics of water polo players were measured at the stage of preliminary basic training using the complex for psychophysiological testing "Neurosoft-psychotest". Indicators of simple visual-motor reaction, discrimination reaction, choice reaction, resistance to obstacles, reaction to a moving object and power endurance of the hand were taken into account. It has been established that water polo at the stage of the preliminary basic preparation will lead to a high accuracy of the reaction to the rough object, and also with this type of reaction, the number of reactions outweighs the number of reactions of delay. Conclusion. Because of the conducted research, the relevance of the study of psychophysiological characteristics in water polo is substantiated. The psychophysiological characteristics of water polo players at the stage of preliminary basic training were determined according to the following indicators: simple visual-motor reaction, discrimination reaction, choice reaction, reaction to a moving object, assessment of power endurance of the hand and resistance to obstacles. Water polo players at the stage of preliminary basic training are characterized by a high speed of a simple visual-motor reaction, at the level of 207.8 mms, as well as a high concentration of attention and the strength of nervous processes. High resistance to obstacles of water polo players at the stage of preliminary basic training is observed. The determined characteristics are possible to be used as model parameters of water polo players at the stage of preliminary basic training

ОСОБЛИВОСТІ НЕЙРОДИНАМІЧНИХ ТА ПСИХОФІЗІОЛОГІЧНИХ ФУНКЦІЙ ДІТЕЙ 5-7 РОКІВ З РІЗНИМ РІВНЕМ ЗОРОВОГО ТА СЛУХОВОГО СПРИЙНЯТТЯ

Introduction. The period from 5 to 7 years attracts special attention from scientists, as it is a sensitive and critical stage of individual development of the child's body.Most domestic and foreign scholars emphasize the need of selecting the content, forms and methods of teaching in accordance with age and gender. However, the peculiarity of the study is that during training should also take into account the psycho-physiological and neurodynamic characteristics of the development of participants in the educational process and adjust teaching methods based on them for more effective perception of certain information by children.The formation of visual and auditory perception for children 5-7 years, as an indicator of readiness, is one of the main cognitive functions, which is formed due to interanalytic complexes of nerve connections and maturity of the cerebral cortex.Therefore, significant attention should be paid to the invariant and variable component of the "New Ukrainian School" of the Standard curriculum of general secondary education for grades 1-2 and preschools, developed under the leadership of O. Savchenko [1], for improving cognitive development and prevention of maladaptation changes in the body during training.Purpose. The aim is to study the features of neurodynamic and mental functions of children of preschool and primary school age with different levels of visual and auditory perception.20 Серія «Біологічні науки», 202 2Methods. The observation was carried out on children aged 5-7 of two educational institutions "Secondary schools of I degrees - preschool educational institutions" No 41 and No42 of Sumy (n = 246).The method of assessment of auditory memory "Learning 10 words" (A.R. Luria, 1973) for informative study of memory was chosen. Determination of the volume of visual random memory was performed according to the method of Shipitsyna LM.M.V. Makarenko’s method on the computer complex “Diagnost-1” was used to determine individual-typological features of higher nervous activity of children.Results. The highest rate of auditory memory was recorded for children aged 6 and 7 years, in contrast to children aged 5 years, in whom the development of cognitive processes was carried outthrough visual perception. Children 5 years of age had longer latent periods obtained during sensorimotor response of varying complexity and lower results of SNP, FRNP, PGM during mental stress in contrast to children 6 and 7 years.A similar trend was also observed among boys aged 5-7 compared to girls in this age group.According to the results of neurodynamic studies, it was found that the best values of SNP, FRNP, PGM and shorter latent periods of SVMR, RC1-2, RC1-3, RC2-3 were obtained for individualswith high levels of visual and auditory perception.Originality. The idea of neurodynamic and psychophysiological functions of children 5-7 years with different levels of visual and auditory perception is expanded.Conclusions. The importance of psychophysiological and neurodynamic functions of children 5-7 years with different levels of visual and auditory perception to prevent maladaptation in the educational process was substantiated.Key words: children; cognitive development; functional mobility of nervous processes; strength of nervous processes; sensorimotor systems.

Conclusions. Improving the strength of nervous processes in the structure of psychophysiological readiness of student youth indicates the promotion of domestic and professional activities. This also indicates a fact that the implementation of training programs at different individual and motivational levels of swimming training system has a positive effect on psychophysiological qualities, reactions, variants of complex visual and motor reaction and tapping test indirectly indicates the acquisition of abilities to general performance.

Порівняльна характеристика психофізіологічних функцій військових та цивільних льотчиків

The aim of the study was to determine the characteristics of the psychophysiological functions of 363 military and 110 civilian pilots by comparative analysis of the results of evaluating their values and the structure of correlation relationships. The analysis of the obtained data was carried out using the well-known methods of variation statistics and correlation analysis. It was shown that among military pilots the best were indicators of neurodynamic functions, attention and reliability of task performance, and among civilians – orientation in space and short-term memory. In the group of military pilots, psychophysiological functions are fairly well correlated with each other and are closely related to most of the personified characteristics, forming 45,5 ± 6,1% of relationships of the maximum number. Among civilian pilots, there are fewer such relationships 24,2 ± 5,3%; there is no correlation between psychophysiological functions and personified characteristics. The regulation of possible negative shifts in psychophysiological functions and the reliability of mission performance in military pilots is carried out primarily as a result of the stabilizing effect of the balance of nervous processes and, to a lesser extent, the strength of nervous processes and orientation in space. Among civilian pilots, such regulation is fairly evenly distributed between the balance of nervous processes, attention, orientation in space, and short-term memory.

Study the influence of physiological and hygienic elements a healthy lifestyle on the functional state and performance of students at a pedagogical university

Introduction. Now, around the world, much attention is paid to an issue of timely receiving quality education. Training process always was and remains rather difficult type of work and demands from the pupil not only sufficient motivation, but also some other, not less important psychophysiological qualities of the personality. One of such obligatory qualities is presence at the studying health which is shown an optimum functional condition and high level of working capacity. Purpose. The research of influence of excessive pastime on the Internet on a functional condition and intellectual efficiency of second-year students of a bachelor degree of pedagogical higher education institution was the purpose of this work. Material and methods. Second-year students of a bachelor degree of pedagogical higher education institution, at the age of 19-20 years, daily carrying out more than 5 hours at the computer, from among which they were created control (n = 19) and experimental (n = 21), of group acted as examinees. To all respondents examination with assessment of initial level of the key psychophysiological indicators then respondents of experimental group observed a high security of work and rest was conducted. Results. After three-months realization of the studied elements of a healthy lifestyle at examinees of experimental group authentically significantly in comparison with reference values indicators the test health activity mood (for 29.0%), critical frequency of flashings (for 4.3%), difficult sensomotorny reaction to light (for 23.5%), operating with spatial representations and intelligence (by 25.9%), the strength of nervous processes and tests of Gencha improved (for 17.8%). Conclusion. Three-months observance of a rated work-rest schedule authentically significantly improves a functional condition and intellectual efficiency of second-year students of a bachelor degree of pedagogical higher education institution. However, the positive effect reached as a result of use of health saving behavior model gradually is lost on condition of return of examinees to initial behavioural concepts.

Взаємозв’язок основних характеристик нервових процесів із вмістом натрію у крові корів залежно від пори року

The type of higher nervous activity determines individual differences and the body's ability to adapt to changing environmental conditions. The most perfect adaptation is provided by a combination of high strength, mobility and balance of nervous processes. It was found that the strength of nervous processes both in summer and in winter was inversely related only to the sodium content in blood cells (r = -0.57–0.71; p<0.01). The balance of excitation and inhibition processes in the cerebral cortex in summer was inversely correlated with the sodium content in whole blood (r = -0.56; p<0.05) and blood cells (r = -0.64; p <0.01), in winter – in blood serum of cows (r = 0.62; p <0.01). It is proved that in summer the effect of the balance on the sodium content in whole blood was ղ²х = 0.29 (p <0.05), in blood cells – ղ²х = 0.63 (p<0.001), and in winter in blood cells – ղ²х = 0.37 (p<0.05). In summer, the mobility of nervous processes to a greater extent limited the sodium content in blood of cows than in winter. Thus, the effect of this indicator of cortical regulation on the sodium content in whole blood and blood cells in summer reached ղ²х = 0.25–0.35 (p<0.05), and in winter in blood cells – ղ²х = 0.24 (p<0.05).

MAIN INDIVIDUAL AND TYPOLOGICAL PARAMETERS OF HIGHER NERVOUS ACTIVITY IN YOUNG PEOPLE OF DIFFERENT SOMATOTYPE WITH NORMAL AND HIGH BLOOD PRESSURE

Background. The individual and typological features of the central nervous system are interpreted as highly genetically determined. Each somatotype is characterized by morphofunctional features of the activity of different systems, including the circulatory system.
 Objective. The aim of the research was to study the features of the main individual and typological parameters of higher nervous activity in persons of different somatotype with normal and high blood pressure (BP).
 Methods. In the control group of the surveyed patients the BP value corresponded to the optimal level according to the WHO classification (125 people). The second group consisted of individuals, whose systolic blood pressure exceeded 130 mmHg at the time of the study and (or) diastolic – 85 mmHg (135 people). Somatotyping technique by Carter and Heath was used. Functional mobility (FMNP) and strength of nervous processes (SNP) were determined using the Diagnost-1 program (Makarenko and Lizogub).
 Results. In the individuals with predominance of ecto- and mesomorphic somatotype component, higher levels of major nervous processes were reported in response to strenuous processing of information, which was associated with more advanced mechanisms of information processing, its neurophysiological support. In people with endomorphic somatotype the lower levels of FMNP and SNP were clearly detected that could indicate that the speed characteristics of the nervous processes in them are at a lower level.
 Conclusions. In normal blood pressure, the highest indicator of FMNP was found in the individuals with predominance of ecto- and mesomorphic component. In the group with high blood pressure, the indicator at the level below the average was in endomorphs. Predominance of the ectomorphic component tended to increase in the surveyed, and in the mesomorphs was at the average level. The lowest level of SNP was found in the individuals with endomorphic somatotype of both groups.

RELATIONSHIP BETWEEN NEURODYNAMIC CHARACTERISTICS AND FUNCTIONAL PREPAREDNESS OF MUSCLES IN ATHLETES OF DIFFERENT SPORTS

Aim. The article is aimed at studying the relationship between the neurodynamic characteristics of athletes of different sports and the indicators of physical fitness obtained during exercise tests. Materials and methods. The study involved male athletes aged 16–21 years, involved in swimming (20 people) and powerlifting (16 people), having sports ranks from the 2nd adult to a candidate for master of sports. The volume and concentration of attention, the speed of eye-hand coordination, the level of functional mobility, the strength of nervous processes, the response to a moving object and the tapping test were processed using an automated program. Indicators of aerobic and speed - strength fitness of the muscles of the lower extremities were determined by the cycle ergo meter tests. Results. Swimmers differed from power lifters by a smaller volume, but better concentration of attention, higher dynamism and strength of nervous processes, less pronounced excitement in the central nervous system, high rates of aerobic energy supply and a less pronounced correlation between the functional indicators and psychophysiological characteristics. In both groups, negative correlations of aerobic performance with the speed of visual motor responses and positive correlations with the balance of nervous processes were revealed. Speed-strength indicators are better for athletes with a high functional mobility, dynamism and strength of nervous processes. Conclusion. There is a correlation between the neurodynamic characteristics and indicators of functional fitness, which must be taken into account when interpreting the results of stress tests and developing individual recommendations based on the results of the examination.
