Functional Changes

Introduction. Maintaining and strengthening young athletes’ health is very important since a growing body is more sensitive than an adult one. The overload on young athletes’ bodies’ functional systems is much higher compared to their peers who do not engage in intense physical activities and sports. This study aimed to assess the functional changes in the body of young athletes practicing sports games in the training process. Materials and methods. The functional state of the body of young athletes practicing five types of sports (volleyball, basketball, football, tennis, and handball) was studied on a representative group of 94 people, of which 50 (53.2%) males and 44 (46.8%) females with an average age of 17.7 ± 0.19 years. The cardiovascular system, central nervous system, respiratory system, and musculoskeletal system were investigated. The functional state assessment was carried out, taking into account the degree and direction of changes in the dynamics of training of individual indicators and integral indicators. It was determined the degree of risk of developing adverse functional changes. To identify premorbid states, we establish the type of self-regulation of blood circulation. Results. The obtained results in this study indicate that significant changes express the biological significance of the response of athletes to the conditions of training in the indices of the functions of the cardiovascular and central nervous systems and the musculoskeletal system. The indices of the functional state of the young athletes’ body at the end of the training changed in both directions. The degree of their severity fluctuated within limits from little too clearly expressed values. On the part of the cardiovascular system, an acceleration of heart rate from 60.1 ± 0.93 to 123.1 ± 0.93 beats/min (p < 0.001) was noted, an increase of systolic blood pressure from 101.1 ± 2.84 to 129.2 ± 1.40 mm Hg. (p <0.001), diastolic arterial pressure from 65.8 ± 1.60 to 76.3 ± 1.20 mm Hg. (p < 0.001), pulse pressure from 33.5 ± 2.35 to 71.5 ± 0.85 mm Hg. (p < 0.001), systolic pressure from 78.3 ± 1.75 to 84.2 ± 1.06 ml (p < 0.001), minutes volume from 4.3 ± 0.22 to 10.3 ± 0.11 l (p < 0.001), total peripheral resistance from 934.2 ± 42.11 to 1646.4 ± 37.61 dyn•s/cm5 (p < 0.001). On the part of the central nervous system, there was an increase in visual motor reaction from 236 ± 20.0 to 389 ± 5.3 ms (p < 0.001) and the auditory-motor reaction from 160 ± 3.8 to 256 ± 7.7 ms (p < 0.001). Young athletes who play volleyball have a higher load on the cardiovascular system. Functional changes are more pronounced in female athletes. The risk of developing unfavorable functional changes was noted for 15 physiological indices. The relative risk varied within 1.03-2.45 for boys and 1.04-2.90 for girls. The most pronounced risk is characteristic for total peripheral resistance (RR = 1.60), minutes volume (RR = 1.58), systolic pressure (RR = 1.55) in boys and systolic pressure (RR = 2.35), minutes volume (RR = 2.21), systolic arterial pressure (RR = 1.75), diastolic arterial pressure (RR = 1.73) and peripheral blood pressure (RR = 1.52) in girls. Conclusions. When playing sports games, a specific professional environment for different types of sports games is formed, this harming the functional state, performance, and health of young athletes.

Autonomic Nervous

The control of cardiovascular system by autonomic nervous system using model-based analysis is very useful to predict blood flow and blood pressure at different locations of human body. The regulation of cardiovascular system by autonomic nervous system is a very complex mechanism, so, an experimental-based model analysis may prove very helpful in studying and analysing its working properly. In this article, a very basic model of cardiovascular system is presented with blood pressure dynamics studied throughout the body. A new bond graph model of the autonomic nervous system embedded with baroreflex system is also presented. Autonomic regulation of ventricular contractility is represented by means of transfer functions. The results in terms of maximum ventricular elastance ([Formula: see text]) and end systolic pressure are shown for two experiments. Another alternative modelling approach to represent the function of nervous system action in blood pressure regulation in terms of an overwhelming controller has been proposed. This controller overwhelms the system properties and therefore helps in managing the unmodelled parts or properties of a system and makes it impeccable for controlling complex systems. All the results and simulations are obtained using Symbols Shakti® software (Bond graph software).

The apparatus designed by the author is an oscilloscilloscope, which serves to measure the oscillation range (oscillations) of the pulse wave and determine the mean blood pressure. The latter is currently given great importance by a number of authors for evaluation of the functional state of the cardiovascular system, since the mean blood pressure is considered to be a value really corresponding to intra-arterial pressure.

Introduction. The study of the physiological status of representatives of power structures at different stages of service is very relevant.Purpose: a comprehensive assessment of the functional state of the body of OMON fighters before and after a 4-month business trip on perform a special task associated with health and life risks. Materials and methods. 34 OMON fighters of the Komi Republic were examined before the trip and after a 4-month trip to the North Caucasus, where they constantly experienced stress. To assess the functional state of the body, a complex of anthropometric, physiometric, psychophysiological, physiological and biochemical studies was used.Results and its discussion. Before the trip, the fighters showed an increase in the time of the visuomotor reaction, the index of functional changes, the myocardium index, the centralization index, the activity index of regulatory systems, blood pressure indicators and other changes that indicate the activation of free radical oxidation processes, and the appearance in individuals of prenosological and even premorbid conditions. In most of the examined patients, a shift in the autonomic balance was found towards strengthening the sympathetic link in the regulation of heart rhythm. Hypovitaminosis was found in many fighters. After a trip, the functional state deteriorated in most indicators (increased blood pressure, personal anxiety, cholesterol, etc., decreased life index and hemoglobin content, etc.) and the number of people with depleted regulatory systems almost doubled.Conclusion. In general, the body of OMON fighters experiences increased functional stress with signs of obvious stress both before a trip to an area dangerous for health and life, and in the first days after returning to places of permanent residence in the North. In this regard, they need additional health and rehabilitation measures related to optimization of the regime of work and rest, activation of physical education, rationalization of nutrition and strengthening the work on the psychological impact.

Research  background  and  hypothesis.  Traditional  time  series  analysis  techniques,  which  are  also  used  for the analysis of cardiovascular signals, do not reveal the relationship between the  changes in the indices recorded associated with the multiscale and chaotic structure of the tested object, which allows establishing short-and long-term structural and functional changes.Research aim was to reveal the dynamical peculiarities of interactions of cardiovascular system indices while evaluating the functional state of track-and-field athletes and Greco-Roman wrestlers.Research methods. Twenty two subjects participated in the study, their average age of 23.5 ± 1.7 years. During the study standard 12 lead electrocardiograms (ECG) were recorded. The following ECG parameters were used in the study: duration of RR interval taken from the II standard lead, duration of QRS complex, duration of JT interval and amplitude of ST segment taken from the V standard lead.Research  results.  Significant  differences  were  found  between  inter-parametric  connections  of  ST  segment amplitude and JT interval duration at the pre and post-training testing. Observed changes at different hierarchical levels of the body systems revealed inadequate cardiac metabolic processes, leading to changes in the metabolic rate of the myocardium and reflected in the dynamics of all investigated interactions.Discussion and conclusions. It has been found that peculiarities of the interactions of ECG indices interactions show the exposure of the  functional changes in the body at the onset of the workload. The alterations of the functional state of the body and the signs of fatigue, after athletes performed two high intensity training sessions per day, can be assessed using the approach of the evaluation of interactions between functional variables. Therefore the evaluation of the interactions of physiological signals by using time series analysis methods is suitable for the observation of these processes and the functional state of the body.Keywords: electrocardiogram, time series, functional state.

In August, 1903, I published a paper in the ‘Journal of Pathology’(1) in which I demonstrated a method experimentally producing uncompensated hear disease in an animal, which was compatible with life. This method consisted in diminishing the size of the pericardial sac by stitches, so that the diastolic filling of the heart was impeded. The main symptoms of this condition were dropsy and diminution in the amount of urine excreted. As the immediate result of this interference with the action of the heart, there occurred a rise of pressure throughout the whole systemic venous system extending as far back as the capillaries, and a fall of the mean arterial blood-pressure. Further, I found that the pressure in all the veins fell to the normal limit again within the space of about one hour, and that subsequently when dropsy was being produced, the vanous pressure in all parts of the body was normal, and the arterial pressure had almost recovered itself.

The article presents the results of a clinical and instrumental examination of 80 healthy women (average age 32,313,57 years) in order to assess the heart rhythm disturbances after induction of superovulation duringin vitrofertilization. All women were examined twice before and after induction of superovulation during extracorporeal fertilization. Clinical and instrumental examination included: electrocardiography at rest; echocardiography; 24-hour ECG monitoring with heart rate variability analysis; 24-hour blood pressure monitoring. Induction of superovulation is associated with a significant increase in mean daily HR max (р0,01), and consequently with an increase in myocardial oxygen demand. It has been established that induction of superovulation contributes to the development of supraventricular arrhythmias (р0,01) and an increase in episodes of apnea/hypnea (р0,01). Regression analysis revealed predictors of supraventricular arrhythmias after induction of superovulation, including adverse circadian heart rate profile, adverse circadian blood pressure profile, impaired autonomic regulation of heart activity (р0,01). It was shown that the appearance of rhythm disturbances is associated with both the initial functional state of the cardiovascular system and its response to the induction of superovulation. It was established a correlation between the estradiol concentration and the increase of daily average heart rate after induction of superovulation (r=0,30,р0,05), apnea/hypnea index after induction of superovulation (r=0,34,р0,05). Conclusion. Superovulation induction may exacerbate existing chronic cardiovascular diseases. Due to the adverse effect of superovulation induction on the daily heart rate profile, women need to evaluate the functional state of the cardiovascular system duringinvitrofertilization planning. This will prepare the woman for the upcoming procedure and avoid adverse reactions from the cardiovascular system in response to stimulation of superovulationin vitrofertilization.

The Difference

Every child will go through several stages in his or her life. They are different from each other as they are in the process of development of cognition, physics, emotion, and personality. For many children, a visit to the dentist can raise their anxiety. This anxiousness will lead to stress that influences the cardiovascular function in the body. The purpose of this research was to determine the difference in pediatric blood pressure between middle childhood and late childhood prior to dental treatment. This research was a clinical trial, pure experimental study. The sample consisted of 30 children within the range of 4-12 years old where they were divided into two groups of age; middle childhood (4-7 years old) and late childhood (8-12 years old). The blood pressures were measured before any dental treatment began and the values were recorded. The data were then analyzed using the One-Sample T-Test analysis. The results of blood pressure in middle childhood and late childhood were compared to the average mean values for each age group. It showed that there was a significant difference in the systolic pressure, which was found higher in the middle childhood group compared to the late childhood. From the result can be concluded that there was a difference in the pediatric blood pressure between middle childhood and late childhood prior to dental treatment.

The article provides the results of determining the level of physical development of the 1th-2nd course students of design specialties of the College of Construction, Architecture and Design. The physical development of students was determined by indicators of harmony of the bodybuilding (Kettle index 2), functional state of the cardiovascular system (Ruffier index), and respiratory system (Stange test). Length and weight of the body, heart rate, breathing delay time were measured. As a result of the researches, the “average” level of the physical development is determined in the 1th-2nd course girls and “sufficient” - in boys. Thus, mass-growth indicators of students according to the calculation of Kettle 2 index, both boys and girls correspond to the assessment of 5 points, which indicates a harmonious physique of students; indicators of the functioning of the cardiovascular system (Ruffier Index) of 1st year boys and the 2nd year students make 2 points, which corresponds to the ”below average” level, and the results of the 1st year girls equal to the assessment of 3 points, “average” level; indicators of the functional state of the respiratory system (Stange test) of boys of the 1th-2nd  course correspond to the assessment of 4 points (“above the average” level), and girls of both courses - 3 points (“average” level). In the age and gender aspects, physical development indicators, in general, don’t significantly differ with the general tendency to increase results with age and the dominance of boys over such in girls. The exception is the Ruffier index, where there is an opposite trend - the results decrease with age in girls and they are higher than in boys. Thus, the results of the research indicate the feasibility of introducing the 1th-2nd course students of professional pre-high education of special physical exercises into the process of physical education to improve the functional state of the cardiovascular and respiratory systems.
