The Relationship

Mechanisms of regulation of cardiac rhythm have many individual features, which are conditioned by age, sex, training of the organism, strength and nature of external influence, constitutional features of the organism. The purpose of the work is to determine the relationship between cardiointervalographic indices and parameters of the external structure of the body in highly skilled wrestlers of the mesomorphic somatotype. The study involved 24 wrestlers between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All of the wrestlers were of medium weight and engaged in free and Greco-Roman wrestling. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). The indices of vegetative homeostasis according to Bayevsky, variational heart rate, statistical and spectral cardiointervalographic indicators were determined. Anthropometry was performed according to the method of V.V. Bunak (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1992). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. It was found that in the wrestlers of the mesomorphic somatotype, the variations of the pulsometry had the highest number and strength of reliable correlations with constitutional parameters, most of which were inverse of the mean force. All statistical indicators of heart rate variability with indicators of the external structure of the body had only inverse significant correlations. The least significant correlations were found for spectral indices and parameters of vegetative homeostasis. According to the results of the correlation analysis in the wrestlers of the mesomorphic somatotype, we can assume that with the increase of total, longitudinal, circumferential, transverse body sizes and muscle and bone mass, the variability of the heart rhythm of the sympathetic department of the autonomic nervous system will be more pronounced.

The topic of sports, physical fitness and adaptive abilities of a person to the influence of physical activity of different intensity has become highly relevant in recent years. The aim of the work is to establish correlations between the indicators of heart rate variability and parameters of the external structure of the body in young athletes of mesomorphic somatotype. The study involved 29 athletes between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All athletes had a track and field athletic load with maximum (100 m, 200 m and 110 m hurdles) and submaximal (running on 400 m and 800 m) work intensity. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). Variable heart rate, statistical and spectral cardiointervalographic indices were determined. Anthropometry was performed by the Bunak method (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1921). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. Cardiointervalographic findings were found to be statistically significantly correlated with a small number of body sizes and somatotype components and body weights in adolescent athletes belonging to the mesomorphic somatotype. Indicators of variational heart rate did not have numerous reliable and unreliable relationships of average strength with somatic parameters. The data of correlation analysis of indices of variational pulsometry showed that in athletes with increase in width and thickness of the torso and decrease in the circumference of the shin and chest was more pronounced sympathicotonia, and with the reduction of fat component increased the influence on the heart of the parasympathetic system. Statistical indicators of heart rate variability with constitutional parameters had significant inverse correlations of mean power. Among all statistical indicators of heart rate variability, the PNN50 had the strongest and most significant correlations with anthropometric dimensions. The least significant correlations with constitutional characteristics in mesomorphic athletes had spectral indices related to skin-fat thickness, trunk diameters, and lower limb segment circumferences.

Objective: This study determines the relationship between the fatigue of adolescent swimmers in high-level competitions during two continuous periods of maximum performance and the degree that swimmers conform to norms during these periods. Methods: We evaluated the conformist trait and three areas of fatigue in two consecutive competitive periods, in 25 young elite swimmers. The measures were evaluated before (_B) and after (_A) of pre (t1; t3) and pos (t2; t4) competition in each period. Millon Adolescent Clinical Inventory was applied for identifies the more adherens (AD; n=12) or detached from the norm (DN; n=13) conformist traits. Wingate test, Heart rate variability (RMSSD; SDNN), WISC-V, and Stroop test were evaluated. Results: DN group present lower fatigue in t1 but an increase in t2, t3, and t4. AN present higher RMSSD_B and SDNN_B in t1. In t3, the mental fatigue of DN was correlated negatively with RMSSD_B; SDNN_B. Both groups had more SDNN_B than SDNN_A in t4. Conclusions: Physical fatigue was important conditioning in both groups, however, the DN group may be more sensitive to physiological and mental fatigue directly affecting the performance.

There have been numerous studies on the relationship between sleep and depression, as well as the relationship between sleep and depression, and heart rate variability (HRV), respectively. Even so, few studies have combined 24-h HRV analysis to study sleep quality and depressive symptoms. The purpose of this cross-sectional study was to investigate the relationship between depressed symptoms, sleep quality, and 24-h HRV in medical students. The particiants were all students at a medical university in Guangdong province, China. A total of 74 college students participated. They were asked to complete a questionnaire that included the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory-II (BDI-II), the Positive and Negative Affect Scale (PANAS), and 24-h ECG monitoring. The results showed that 41.7% of the medical students had poor sleep quality, with higher levels of depressive symptoms and more negative emotions, and there was no difference in 24-h HRV indices between the low PSQI group and the high one. Correlation analysis showed that there was a significant relationship between sleep quality and depressive symptoms (r = 0.617), but the relationship between 24-h HRV indices and PSQI global scores, BDI scores were not significant. However, the correlation analysis of PSQI components and 24-h HRV showed that sleep disturbance was significantly negatively correlated with SDNN and LF in waking period (r = −0.285, −0.235), and with SDNN in sleeping period (r = −0.317). In general, the sleep disturbance in PSQI components can sensitively reflect the relationship between sleep quality and 24-h HRV of medical students. Individuals with higher sleep disturance may have lower SDNN during awake period and bedtime period, and lower LF in awake period. Twenty-four hour HRV has certain application value in clinical sleep quality monitoring, and its sensitivity and specificity in clinical application and daily life are still worth further investigation.

Annotation. Appropriate cardiointervalographic parameters establishment, for highly skilled athletes of a particular sport, is relevant and can be used for diagnostic purposes and because of connection with the widespread prevalence of cardiovascular pathology. The purpose of the work was to construct regression models of the variations of the pulsometry in volleyball players of the mesomorphic somatotype, depending on the features of anthropometric indicators. The study involved 24 volleyball players with a high level of sportsmanship (from the first adult category to candidates for the master of sports), aged 17–21 years. We carried out anthropometric research by Bunak's method (1941), somatotypological - by the calculated modification of the Heath-Carter method (1990), determination of the component composition of the body weight by the method of Matejko (1992) and cardiointervalographic examination using a computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association [1996]. The following indicators of variation heart rate were determined: moda, moda amplitude, average minimum and maximum R-R intervals, and variation range. The mathematical models were constructed in the “STATISTICA 5.5” package for Windows using direct stepwise regression analysis. The article presents the results of regression analysis for determining the dependence of variation heart rate indicators in volleyball players of mesomorphic somatotype on the total complex of constitutional characteristics. Mathematical models for determination of individual proper cardiointervalographic parameters based on features of the external structure of the body of youth volleyball players of high level of sportsmanship. The analysis of constitutional predictors that determine the variability of indicators of variation heart rate in a group of volleyball players of mesomorphic somatotype has been performed.

Currently, the problem of improving the quality of the training process in both professional and novice athletes is a priority for experts in the medical and biological support of sports all over the world. For these purposes, various biofeedback procedures, including the method of solving specialized motor-cognitive tasks on the stabilometric platform [1], have been actively used in recent years as extra-training means to improve sports performance. At the same time, we should note that one of the most informative biological signals that allow to judge about the change in the functional state of the body of the tested athletes in the process of sports training is the dynamics of heart rate variability (HRV) [2]. HRV analysis is widely used as a non-invasive and reliable tool for assessment of vegetative control of human cardiovascular system [3]. Numerous literature sources confirm the prospect of using this method for the purposes of sports physiology [4] However, changes in HRV in highly qualified athletes when solving complex motor and cognitive tasks, as of today, still remain unstudied. The aim of the present study was to assess changes in heart rate variability in highly qualified orienteering athletes when solving complex coordination tasks on biocontrol of a virtual object using a stabilometric platform ST-150. Seven days training with biofeedback control on the stabilometric platform resulted in a significant increase of such HRV temporal indices as SDNN – by 8,9 % (p<0,01), RMSSD – by 42,3 % (p<0,05), pNN50 – by 77, 1 % (p<0.05), CV – by 25.3 % (p<0.01), as well as heart rate reduction by 10.5 % (p<0.05), which indicates an increase in functional capabilities of the athletes’ bodies, strengthening vagus effects on cardiac rhythm. The results of geometrical analysis have shown that biofeedback according to reference reaction leads to reliable increase of values of index of mode of cardiointervals by 9,7 % and increase of variation range of histogram of cardiointervals by 21,4 % as well as decrease of values of mode amplitude by 19,2 % and tension index of regulatory systems of the body by 29,6 % (p<0,05), which testifies to improvement of adaptation possibilities of the body of tested sportsmen under the influence of this type of biocontrol. Analysis of spectral components of heart rhythm in orientation athletes after 7-day training with biofeedback control has shown significant increase in TP by 36 %, LF – by 37,7 %, HF – by 88,2 % as well as decrease in LF/HF by 28,2 % (p<0,05), which testify to increase in general variability of heart rhythm, activation of parasympathetic regulation circuit, increase in functional capabilities and reserves of tested athletes organism.

Specific extreme climatic conditions of the North can cause long-term psychoemotional stress, causing violations of the state of adaptive mechanisms of the body and the formation of psychosomatic diseases. Adolescence, due to specific changes in the body, is most susceptible to various stressful factors. The purpose of this work was to study the psychoemotional state and features of the regulatory mechanisms of the body of adolescents living in the North, depending on gender. A study of the level of neuroticism (H) according to G. Eysenck, situational (ST) and personal anxiety (LT) according to Spielberger, analysis of heart rate variability (HRV) using the hardware and software complex "VNS-Spectrum" (LLC "Neuro-Soft", Russia, Ivanovo) in adolescents (n = 58; 30 girls, 28 boys), permanently residing in the city of Yakutsk. Statistical data processing was performed using the program Statistica 13 for Windows. The differences were considered statistically significant at p<0.05. The results show that more than 40% of adolescents (40% - girls, 43% - boys) permanently residing in Yakutsk have a high level of neuroticism, which is significantly higher than in adolescents in Central Russia. Gender differences were revealed in the study of CT and LT. In girls, a high level of CT is detected in 31% of individuals, and a high level of LT is detected in 44%. The values of CT and LT in girls correspond to the average values (40.31±1.85 and 44.06±1.37 points, respectively). Boys have a higher number of individuals with high levels of CT (43%) and LT (54%) than girls. The average CT values are 41.42±1.95 points. Average LT values in boys (45.42±1.56 points), which corresponds to a high level of anxiety. The high level of LT in boys strongly correlates (r = 0.81) with the tension of the mechanisms of regulation of heart activity with the involvement of the suprasegmental Central loop of regulation, which indicates a high level of psychoemotional tension in more than 50% of adolescent boys living in Yakutia.

Cardiac Autonomic Activity

The literature indicates stress as a response of the organism to a stimulation that requires enormous efforts to adapt to the changes in the environment and the body. When an individual is subjected to stress, the autonomic nervous system is triggered, the sympathetic pathway is activated, and the parasympathetic system is suppressed, which exerts several effects on the cardiovascular system and affects heart rate variability. This research aimed to conduct a literature review to find and analyze the studies that address clearly the implications of stress on heart rate variability. The methodology employed was an active search in the databases SciELO, PubMed and Lilacs. The results were five articles, most of which suggest a relationship between stress and heart rate variability. We observed that the majority of the studies indicated a strong association between stress and cardiac autonomic activity. The stress is present in the daily activities of the population, especially in labor. The subject is vast, however, were observed in the references the effects of stress on the body making it vulnerable to diseases. Thus, this information may contribute to the aid of preventive strategies against stress and diseases of the cardiovascular system.

The research results showed that the vegetative tone of the nervous system in different phases of the menstrual cycle is different. In accordance with changes in heart rate (HRV) indicators, we can talk about the predominance of tone of either the sympathetic or parasympathetic department of the autonomic nervous system in each phase of the cycle, to distinguish subgroups of students by the distribution of the tone of the autonomic nervous system during the cycle. It was possible to isolate those HRV indicators that were changed most synchronously (rhythmogram, histogram, and scatterogram indices). The spectrogram indices are distinguished by the highest asynchrony of changes; therefore, it is not very convenient to analyze changes during a cycle. Autocorrelation indicators reflect the relationship and the predominance of one of the circuits of heart rhythm regulation (central or autonomous). Despite the fact that a certain dynamic of changes can be traced, significant differences were noted only for some indicators in each of the groups. HRV indicators in accordance with the standards given in the literature should be clarified.

Determining the maladaptation and adaptive capabilities of the body, in particular the cardiovascular system of volleyball player is currently advanced in sports medicine. The aim of the work is to establish correlations between cardiointervalographic indicators and parameters of external body structure in volleyball players of mesomorphic somatotype of juvenile age. The study involved 24 volleyball players aged 17 to 21 with a high level of sportsmanship and more than 3 years of experience. We conducted a study of heart rate variability on the cardiac computer diagnostic complex "OPTW" according to the recommendations of the European and North American Cardiac Association (1996). Indicators of autonomic homeostasis according to Baevsky, variation pulsometry, statistical and spectral cardiointervalographic parameters were determined. Anthropometry was performed by the method of Bunak (1941), somatotypological study – by the calculated modification of the method of Heath-Carter (1990), determination of the component composition of body weight by the method of Matejko (1992), correlation analysis by the method of Spearman was performed in the package "STATISTICA 5.5". Mesomorphic volleyball players were found to have the highest number and strength of reliable correlations with anthropo-somatotypological parameters, most of which were inverse and medium strength. Statistical, spectral parameters of heart rate variability and indicators of autonomic homeostasis with indicators of external body structure had few significant correlations. The girth of the hand in mesomorphic constitution volleyball players was statistically significantly related to the value of all statistical parameters and indicators of autonomic homeostasis by the method of Baevsky. According to the results of correlation analysis, we can assume that in volleyball players of mesomorphic somatotype with increasing the size of the mesomorphic component of somatotype, longitudinal, circumferential sizes and diameters of chest, arm, leg, neck will increase the impact on heart rate variability of the parasympathetic autonomic system.
