Revealing the Peculiarities of Female Students’ Physiological Characteristics with Different Somatotypes in the Absence of Compulsory Physical Activity at University

Objectives. The purpose of the study was to determine the parameters of female students’ physiological characteristics with different somatotypes, which they achieved by exercising outside the university due to COVID-19 quarantine and air raids during the hostilities in Ukraine. Material and methods. The study involved 66 female students aged 17.8 ± 0.6 years, who belonged to different somatotypes and had no reservations about engaging in different amounts of physical activity. The Shtefko-Ostrovsky method, modified by S. Darskaja, was used to diagnose the somatotype. The necessary empirical data were obtained through the performing well-known functional tests that allowed to determine blood pressure, heart rate in different situations, vital capacity, vital capacity index, maximum isometric strength index, and Robinson index. The parameters of these characteristics were determined in female students with each of the four available somatotypes during the study, and each parameter was compared with different somatotypes. The testing was conducted at the beginning (January) and at the end (May-June) of the academic semester, but during one academic year. Results. At the beginning, and even more so at the end of the academic year, the parameters of the studied characteristics in female students with each of the available somatotypes differed from each other (p-values ranging at the level from 0.05 to 0.000). The volumes and conditions of physical activity used during the academic year did not lead to significant changes in the physiological characteristics of all female students, i.e. parameters remained at the previously achieved level. At the same time, the presence of peculiarities caused by the girl’s belonging to a certain somatotype was observed. Conclusions. Identifying the peculiarities in changes of female students’ physiological characteristics’ parameters, taking into account their somatotypes, is a perspective and significant direction for modernization of physical education at university. The obtained data will contribute to the individualization of the content and normative bases of physical education for female students, using information on the manifestation and change of parameters of various characteristics, including physiological ones.

FITNESS LEVEL OF SECONDARY SCHOOL STUDENTS ENGAGED IN SPORTS

School physical education is effective means of providing children with the knowledge for lifelong physical activity. The research was aimed to examine the influence of different sports activities (badminton, basketball, football) on fitness level of boys aged 10-11. 72 boys aged 10-11 were engaged in the research. Evaluation of children’s fitness level involved anthropometric parameters of body length (cm); body mass (kg); hand dynamometry (kg). Cardiovascular and respiratory systems were also assessed: heart rate (HR, bpm) – method of palpation; blood pressure – systolic (SBP, mm Hg) and diastolic (DBP, mm Hg) – method of Korotkoff sounds; vital capacity of lungs (VC, L) – spirometer measuring. The Ruffier index, life index, strength index, the Robinson index and the Quetelet index were considered as well. Summing the points of five parameters, fitness levels were defined as low, below average, average, above average, and high. Comparative analysis of ball games influence on children’s fitness level revealed the highest growth rate among badminton players, though their initial and final parameters were the lowest ones. Research findings made it possible to conclude that extramural engagement in ball games throughout school year had beneficial effect on fitness levels of boys aged 10-11.

Optimizing the functional state of the cardiorespiratory system of female students aged 17-19 with the help of a modified program of distance classes in physical education

The article deals with the peculiarities of the impact of a modified program of distance training on physical education on the functional state of circulatory systems and external breathing of students of 17-19 years of higher education. The relevance and practical importance of this study is due to the complex modern conditions of life of our country, the inability to conduct full -fledged classes among student youth and the need to maintain the optimal level of physical and functional state of student youth. The use among female students of the experimental group of the program of remote classes proposed by us contributed to significantly higher rates of improvement in heart rate, all types of blood pressure, Robinson's index, total peripheral resistance of blood vessels, coefficient of efficiency of blood circulation, vital capacity of the lungs (in 2-3 times), breath retention time on inhalation and exhalation (3 and 5 times, respectively), Skibinsky index 5 times, hypoxia index (20 times) and almost 5 times the levels of the functional state of the cardiovascular system and the external system breath. The results of changes in their intragroup distribution by the levels of levels of functional state of circulatory and external respiration, which were reflected in the increase of their representation in functional classes high and above average, were significantly more optimal in the experimental group. Similar changes in the girls of the control group were insignificant. The results testified to the high efficiency of the proposed program of distance classes with the use of fitness and the possibility of its practical use among students of higher education.

Use of indices to assess women’s health in wellness fitness

Background and Study Aim. With increasing focus on women's health and well-being, there's a pressing need for efficient tools to accurately reflect their physical condition and health status. This study aims to substantiate the use of indices as effective instruments for assessing women's health and wellness fitness. Material and Methods. This study involved 40 women, aged 43.33 ± 0.93 years, who participated in a wellness fitness program for 8 months. Sessions were held three times a week, each lasting 1 hour. A comprehensive health improvement program was utilized, incorporating dance aerobics, strength fitness, and stretching exercises. Anthropometric measurements were taken, and the Stange test was administered to calculate 12 health-related indices. The significance of differences was evaluated using the sign criterion (z) and Rosenbaum's Q index. Assessments were conducted both before the initiation and upon completion of the wellness program. Results. Significant changes were observed in several indices, including the Body Mass Index (z=2), Erisman Index (z=0), Vital Index (z=0), Skibinsky Index (z=1), Kerdo Autonomic Index (z=2), Robinson Index (z=3), Waist-to-Hip Ratio (z=11), Systolic Blood Pressure Index (z=5), Diastolic Blood Pressure Index (z=4), and Livy Index (z=0). Additionally, a reliable improvement in the left arm strength index was confirmed using Rosenbaum's Index (Q=7). Conclusions. The results validate the use of specific indices to evaluate the efficacy of wellness fitness programs. Notable improvements were observed in the Body Mass Index, Erisman Index, and Livy Index, indicative of enhanced physical condition and normalization of body mass, particularly significant among overweight and obese participants. An increase in the strength index reflects augmented hand muscle strength, while enhancements in the vital index signal boosted respiratory system functionality. Furthermore, changes in the Skibinsky Index, Robinson Index, and Kerdo Autonomic Index highlight an elevated adaptation capacity of the cardiorespiratory system. The comprehensive set of indices employed offers insights into the cardiovascular, respiratory, and musculoskeletal systems' state. Their applicability at both individual and group levels, combined with the simplicity of calculations, clarity, and informativeness, markedly improves the monitoring effectiveness of health and fitness status.

Dynamics of health and physical development indicators of cadets during their professional training in the field environment.

Aim: To investigate the dynamics of health and physical development indicators of cadets during their field training exercises of various durations. Materials and Methods: The research involved 246 cadets (men) of the 1st-4th training years, who were majoring in the specialty 253 referred to as "Military Management" (specialization "Management of Tank Troops"). The research was conducted in 2022-2023 during field training exercises lasting 2 and 4 weeks. Research methods: theoretical analysis and synthesis of literature, medical and biological methods, testing, statistical analysis. Results: It was found that the level of health and physical development of cadets deteriorates during their field training exercises. The worst level among the studied indicators after the cadets' field training exercises was recorded in the indicators of vital index, Robinson index, and endurance level. It was found that the longer the duration of field training exercises, the more the health and physical development of cadets deteriorates. The most pronounced deterioration in the level of the studied indicators was found in the cadets of junior training years. Conclusions: The deterioration of cadets' health and physical development during their field training exercises has been proven. The most negative changes occurred in the indicators of the cadets' cardiorespiratory system. The results indicate the need to improve the organization and methods of physical training with cadets during field training exercises, which will help maintain their health and physical development at the proper level.

Aim: To study the study the impact of negative factors of professional activities on the health of law enforcement officers. Materials and Methods: The research involved 89 law enforcement officers (58 men, and 31 women) who served for a year in practical police units after graduating from a higher educational institution. Methods: analysis and generalization of scientific and methodological literature, anthropometry, physiometry, testing, and statistical methods. The health status was assessed by body mass index, Robinson index, and vital index. Results: It was found that the body mass index of law enforcement officers for one year of service in practical units deteriorated in both men and women by 1.3 kg/m2 and 0.9 kg/m2, respectively. More negative changes were observed in men. At the same time, after one year of service, the number of men with overweight (27.5 %) and even obesity of the first (13.9 %) and second (5.2 %) degrees increased significantly. In women, the changes were less pronounced. The dynamics of Robinson and vital indices, as well as the level of physical fitness, were also negative. Conclusions: The results of the research indicate a negative impact of professional factors in terms of professional activities on the health of law enforcement officers. It has been found that adherence to the principles of a healthy lifestyle, in particular, a regimen of rationally organized motor activity, is an important area in combating the impact of negative factors of professional activities on the health of law enforcement officers.

THE IMPACT OF BALLROOM DANCING ON THE LEVEL OF PHYSICAL HEALTH OF THE INDIVIDUAL

The article is devoted to examining the impact of ballroom dancing on the level of physical health of the individual. As health-promoting activities increasingly gain attention in contemporary society, this study aims to provide empirical data on the benefits of dance as an alternative to traditional forms of exercise. Specifically, the primary objective of the research is to measure and analyze key morpho-functional indicators of health, such as cardiovascular fitness, muscular strength, and general vitality, to assess whether ballroom dancing can offer a holistic approach to improving individual health. The methodology employed for this study was a longitudinal research design. The study was conducted among students aged 17–20 during the academic years 2021–2022 in an educational institution in Lviv. Fourteen students participated, consisting of an even gender distribution – 7 females and 7 males. Various health indicators were measured at the beginning of the study and after an 8-month period of regular ballroom choreography training. Quantitative methods were used to collect data, including standard tests like the Ruffier index and the Robinson index, which were then statistically analyzed to ascertain any significant changes. The findings indicate a significant improvement in several health metrics. For instance, there was a notable increase in cardiovascular health as indicated by the Ruffier index. Though there were no significant changes in the Robinson index, there was a tendency towards positive dynamics, suggesting that the impact of ballroom dancing may require more nuanced investigation under different states of physical stress. Overall, the results demonstrate that ballroom dancing contributes positively to several aspects of physical health. The practical implications of this research are far-reaching. Given the generally negative attitudes towards traditional physical education classes, ballroom dancing could serve as an effective and more engaging alternative. As novice dancers can achieve a decent level of preparation without much difficulty and as the dance movements involve multiple muscle groups and cognitive functions, this form of exercise is both enjoyable and beneficial.

Improvement of Health and Morphofunctional Status of Law Enforcement Officers of Older Age Groups during the Organized Motor Activities.

With age, there is a tendency for the health of law enforcement officers to deteriorate. This especially applies to instructor officers, whose professional activity is characterized by a significant decrease in the volume of motor activity, overloading of the intellectual sphere, and high neuro-emotional stress. The aim of the research is to investigate the influence of recreational and health-promoting training sessions with physical exercise on the health, physical development, and functional status of instructor officers of older age groups. 62 instructor officers (aged 40-45) of various academic disciplines took part in the research. The instructors of the experimental group (EG, n = 30) were engaged in physical exercises in accordance with the authors' program of recreational and health-promoting training sessions; the instructors of the control group (CG, n = 32) attended the training sessions according to the existing physical training program. It was found that at the end of the experiment, the studied indicators of the EG instructor officers were significantly better than those of the CG ones, according to the indicators of body weight, Quetelet index, the vital capacity of lungs, vital index, strength index, heart rate, arterial blood pressure, Robinson index, and level of physical health. It was established that systematic recreational and health-promoting training sessions have a positive effect on the health level of the instructor officers of older age groups. This will allow them to carry out instructional activities at a high professional level and ensure resistance to adverse factors of professional activities.

THE INFLUENCE OF THE PLANT ADAPTOGENE "VICTORIN" ON THE FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM IN PERSONS WITH INCREASED THERMAL SENSITIVITY.


 
 Abstract. Introduction. Global warming is the most urgent environmental problem today. It has been established that the optimal functioning of the cardiovascular system is necessary for the survival of the human body in the conditions of climate change. Such means as adaptogens are used to increase the body's resistance to adverse environmental factors. 
 The aim of the study. To study the influence of the plant adaptogen "Victorin" on the functional state of the cardiovascular system of healthy individuals with increased sensitivity to heat.
 Research materials and methods. 14 healthy students aged 17-20 years with increased sensitivity to temperature were selected. All persons were suggested to use 1 capsule of the herbal preparation "Victorin" daily in the first half of the day for 30 days. Assessment of subjective changes in the general state, well-being and functional state of the cardiovascular system using the Robinson index, the index of the response of the cardiovascular system to psycho-emotional stress, the Kerdo index, determination of adaptation potential according to the method of R.M. Baevsky was conducted on the 1st, 15th and 30th days of the study.
 Research results. All those examined on the 30th day of the study noted that they feel better heat tolerance, feel more comfortable in conditions of increased ambient temperature. The established tendency to decrease the average value of the Robinson index by 10 n.u. (10.1%), compared to the 1st day of the study. The average value of the index of the response of the cardiovascular system to psycho-emotional stress on the 30th day decreased by 0.147 n.u. (11%) (p<0.01). After a 30-day intake of the plant adaptogen "Victorin", a decrease in the tone of the sympathetic nervous system and its shift towards autonomous balance was revealed. The value of adaptation potential on the 30th day of the study is 9.3% less, compared to the initial indicators (р<0.01). 
 Conclusions. Taking a plant adaptogen in people with a higher sensitivity to heat caused a tendency to increase the reserve capacity of the cardiovascular system and its more economical activity, contributed to an increase in stress resistance, a decrease in the tone of the sympathetic nervous system, and an increase in the adaptation potential.
 

Modern approaches to determining the impact of physical activity on the psychological health of students in wartime

The article analyzes modern approaches to determining the impact of physical activity on the psychological health of students in wartime. Through the use of the meta-analysis method, we have determined that most authors used the following research methods to obtain results on this issue: the SAN method (well-being, activity, mood), body mass index, vital and strength indices, Robinson's index, and the Fremdheim method. Based on the results of their research, it can be argued that sports have a positive impact on the psychological state of students. Systematic curricular and extracurricular physical exercises are an important condition for the normal physical and spiritual development of a student's personality, a prerequisite for fostering priority orientations to health promotion and a motivational incentive for regular independent exercise and sports. Physical activity improves cognitive functions, in particular, increases cognitive performance, memory and cognitive flexibility. Sports can also improve students' psychological well-being by providing a positive mood, reducing symptoms of depression, improving self-esteem, and developing social skills. In addition, sports can help regulate emotions and provide students with psychological comfort and self-discipline, and thus can be used as an additional argument in support of the introduction of physical education and health activities into the curriculum of higher education institutions. Sport can be an effective means of improving students' physical and mental health, contributing to their learning and overall well-being. The main goal of our further research will be to determine the impact of physical activity on the psychological health of students in wartime in non-core higher education institutions in Vinnytsia.

The influence of physical training on indicators of the functional state of the cardiovascular system of young boxers during the stage of initial training

The article is devoted to the problem of assessing indicators of the functional state of young martial artists (on the example of boxing). The goal is to investigate the dynamics of changes in the functional state of the cardiovascular system of young boxers during the stage of initial training. The research was conducted on the basis of "Complex Children's and Youth Sports School for Boxing and Martial Arts" of the DMR during 2021-2022. 35 young athletes participated in the research. It was established that in September 2021, the average group indicators of heart rate and average blood pressure corresponded to age norms; systolic and diastolic blood pressure indicators were higher than the age norm, pulse pressure indicators were lower. The assessment of the Robinson index indicated the predominance of a low level, which indicated the presence of signs of dysregulation in the activity of the CVS; in 80.0% of athletes, the state of adaptation was defined as "satisfactory adaptation". During almost a year of boxing classes (in December 2022), a repeated study confirmed the positive dynamics of the functional state of the CVS: the percentage of athletes who had an average level of the CVS condition increased statistically significantly to 83%, in 97.14% the state of adaptation was defined as "satisfactory adaptation".

Удосконалення витривалості боксерів на етапі спеціалізованої базової підготовки

Purpose: to improve general and special endurance in boxers at the stage of specialized basic training. Material and methods. The following methods were used in the research: theoretical (analysis and generalization of data of scientific and methodical literature, the Internet on the problem of the research, generalization of modern experience of physical training of boxers of different qualification), empirical (testing, experiment), statistical (methods of mathematical processing of the obtained results). The research was attended by 19 boxers of the stage of the specialized basic training, whose average age was 15,21±0,54 years, sports qualification – I-III categories, who made up the control (n=10) and experimental (n=9) groups. Results: taking into account the recommendations of specialists and conclusions of researchers about the use of the training methodology «fartlek» in the training process of highly skilled single combatants, a program of endurance improvement based on a combination of load and rest, taking into account the perspective requirements of competitive activity of a boxer at this age, was developed. The boxers of the control group were trained according to the curriculum for children and youth sports schools by the traditional method. In the training process of the experimental group the program of improvement of endurance by the method of «apron» was introduced in times of physical preparation when the plan of trainings provided a running load. As a result of the experiment the reliable dynamics of changes of indicators of the level of general and special endurance in boxers of the experimental group in comparison with the control group (running on 2000 m (t=5,04; p<0,001); jumping with a rope for 1 min (t=2,80; p<0,05); running on 300 m (t=4,38; p<0,001); striking for 30 s (t=2,79; p<0,05)) was defined. Changes of other indicators of testing of general and special physical fitness of boxers during the experiment improved in each of groups, but have no statistically significant difference between groups (р>0,05). Comparison of dynamics of functional indicators defined their statistically significant improvement in each of groups, but as a result of the experiment there is no significant difference between the experimental and control group on indicators of a condition of a cardiovascular system (t=0,32; р>0,05) and a level of adaptation to a load (t=0,33; р>0,05). By indicators of functional ability of heart muscles (by Robinson index) statistically significant changes and advantage of energy potential of an organism in boxers of the control group (t=3,01; р<0,05), in comparison with the experimental group (t=1,31; р>0,05), changes in which have no statistically significant difference, were defined. Conclusions. The effectiveness of the experimental program of improvement of endurance by the method of «fartlek» in boxers at the stage of specialized basic training is proved, but despite the increase of the level of general and special endurance in the experimental group there was no significant increase of energy potential of the organism of sportsmen. This suggests that the «apron» technique can be used in the educational and training process of adolescents, but requires careful use for this category, taking into account age restrictions.

Physical Activity and cardiovascular function in 9-year-old schoolchildren: implications for health and well-being

Background and Study Aim. Sedentary lifestyles are major risk factors for cardiovascular diseases later in life. Identifying the potential benefits of physical activity for the cardiovascular health of children is crucial for developing effective strategies to promote healthy habits and prevent future health problems. Purpose of the article is to investigate the relationship between physical activity and cardiovascular function in 9-year-old schoolchildren, taking into account the gender.
 Materials and Methods. The study participants were 27 students of the 3rd grade (10 boys, 17 girls) of secondary school № 58 in Kharkiv, Ukraine. All children were healthy and were under the supervision of a medical worker. Consent was obtained from both the school administration and the parents of the children. The functional state of the cardiovascular system of children was determined by the indices of the Robinson index and the Ruffier index. To calculate these indicators, we measured heart rate (HR) and blood pressure (BP) at rest and after exercise (30 squats in 45 seconds).
 Results. There were no significant differences between boys and girls in heart rate, systolic and diastolic blood pressure, heart rate at rest and recovery after exercise. The average level of reserves and efficiency of the cardiovascular system was revealed. A higher than average level of the response of the cardiovascular system to standard physical activity was revealed.
 Conclusions. The results of this study suggest that the functional capabilities of the cardiovascular system of 9-year-old students are generally at an average level and that there are no significant differences between boys and girls in terms of heart rate, blood pressure, and diastolic blood pressure. These findings could be useful for developing physical education programs for children and for identifying children who may require additional cardiovascular health monitoring or interventions.

Функціональні можливості серцево-судинної системи та стресостійкість осіб із різною теплочутливістю

Global warming affects people’s daily life, reduces endurance and work capacity. The purpose of our study is to investigate the functional capabilities of the circulatory system, adaptation potential and stress resistance of individuals with different heat sensitivity. To evaluate the activity of the cardiovascular system, an echocardiographic examination was performed. The reserve capabilities of the heart and the economy of its work were determined using the Robinson index and the Roufier test. Resistance to hypoxia was determined using the Stange and Genchi tests. The degree of oxygen assimilation was evaluated according to the values of maximum oxygen consumption. Cardiorespiratory fitness was determined based on the results of the Rufier test. Adaptation potential was established according to Baevsky’s method. Stress resistance was assessed by determining the response index of the cardiovascular system to psycho-emotional stress. It was established that in people with lower heat sensitivity, the activity of the cardiovascular system is more optimal and more economical and its reserve capacity is greater, compared to higher sensitivity individuals, in which the intensity of its work in an uneconomical mode is increased and the reserve potential is limited. Shorter breath retention time on inhalation and exhalation, respectively, in persons with higher sensitivity to heat indicates a worse oxygen supply to the body. Also, they have a poor ability to absorb oxygen and lower cardiorespiratory efficiency. The predominance of stress adaptation mechanisms and lower stress resistance were also revealed. Thus, our results show that individuals with a higher sensitivity to heat are particularly vulnerable to the negative effects of global warming, which should be taken into account for the prevention of cardiovascular and heat diseases in them in the future.

The impact of the comprehensive use of sports games on the physical fitness of high school students

The results of experimental research on the effectiveness of the comprehensive use of sports games (volleyball, football, basketball, and handball) during extracurricular activities for high school students in physical education have been presented. The aim of the research was to determine the effectiveness of the extracurricular program based on the comprehensive use of sports games to improve the physical fitness of high school students. Research methods included analysis and generalization of data from scientific and methodological literature, pedagogical observations, pedagogical experiment, testing of general and special physical fitness, anthropometric methods of research, physiological methods of research, express assessment of physical health, and methods of mathematical statistics.
 The implementation of the experimental extracurricular program with volleyball games in general contributed to the improvement of overall physical fitness, including an increase in physical performance, development of physical qualities, a decrease in blood pressure, improvement of the general peripheral vascular resistance index, Robinson index, hypoxia index, Skibinski index, improvement of the functional state of the cardiovascular and respiratory systems, improvement of physical health indicators, and improvement of special physical fitness indicators. In high school boys in the experimental group, significant improvement in their physical fitness was recorded compared to boys in the control group. Statistically significant improvements were observed in the level of physical performance, general level of physical fitness (speed-strength, strength abilities, level of agility, endurance, and flexibility), special physical fitness indicators, functional state, functional fitness, and physical health indicators. The analysis of the results of the pedagogical experiment suggests a high potential for the proposed approach to improve the system of extracurricular activities in physical education in secondary education institutions.

SOMATIC HEALTH INDICATORS OF FUTURE POLICE OFFICERS

Abstract: In our research, the level of somatic health of cadets of the National Academy of Internal Affairs of the first, second and third years of study was determined.
 The aim of the research was to determine the level of physical health indicators of future police officers at the institution of higher education of the Ministry of Internal Affairs during training.
 The research showed the dynamics of physical health indicators from the first to the third year of study.
 The research used theoretical analysis and generalization of scientific and methodical literature, pedagogical testing, methods of mathematical statistics, medical and biological methods. We used diagnostic express system of H.L. Apanasenko to determine the level of physical health.
 The results of the examination of the cadets of the Academy of Internal Affairs indicate that the body mass index of most of the examined corresponds to the average level. Lung volumes indicators showed that 80% of the examined cadets had an insufficient level of development and functional capabilities of the respiratory system. Analyzing the results of the strength index, we can state that this indicator is insufficiently developed in 2/3 of the examined cadets (74%). The indicators of the Robinson index show that in most (92%) of the cadets examined at all courses, the activity of the cardiovascular system according to this indicator is insufficient. The analysis of indicators of pulse response to load shows that 1/2 of the examined (52%) cadets have an insufficient level of functional reserves of the cardiovascular system. We found that the vast majority of examined cadets (85%) of the Academy of Internal Affairs have poor physical health and are outside the safe level (low, below average and average levels of somatic health).

Physiological Characteristics of Young People in the Absence of Mandatory Physical Activity Required at the University

The purpose of the study was to determine the parameters of the physiological characteristics of young men with different somatotypes, which they achieved by performing physical activity in the conditions of the Covid-19 quarantine. Materials and methods. 39 young men aged 17.6±0.5, who had no restrictions in the use of different amounts of physical activity and belonged to different somatotypes, took part in the study. Somatotypes were diagnosed using the Shtefko-Ostrovsky method in the modification of S. Darskaja. To obtain the necessary data, well-known functional tests were used to establish blood pressure, heart rate in various states, vital capacity, vital capacity index, index maximum isometric strength, and Robinson index. We evaluated the parameters of these characteristics in representatives of each somatotype during the academic year and compared these parameters in different somatotypes. In the latter case, the results at the beginning (January) and at the end (May-June) of the study were used; they lasted for one academic year. Results. At the beginning, and to an even greater extent at the end of the school year, the parameters of the studied characteristics in the representatives of the existing somatotypes differed among themselves (p at the level from 0.05 to 0.0001). The volumes and conditions of physical activity used during the academic year led to the deterioration of the physiological characteristics of all young men. However, there were peculiarities caused by belonging to a certain somatotype. Conclusions. Establishing the specifics of changes in the parameters of the physiological characteristics of young freshmen, taking into account their somatotypes, is an important task for the modernization of physical education in a higher education institution. The obtained data contribute to the individualization of the substantive and normative foundations of physical education of young people, using for this purpose data on the manifestation and change of parameters in various characteristics, including physiological ones.

Dynamics of indicators characterizing the health of children in the territory of military conflict. The impact of rehabilitation measures: cohort study

Background. There are still understudied issues concerning the health indicators of children who are in conditions of conducting warfare in primary school age. Objective. The aim of the study is to evaluate comprehensive rehabilitation measures to optimize health indicators (physical, functional and mental capacity parameters) of primary school children in conditions of military conflict.Methods. An examination of 419 elementary school children was conducted in the period from March 2022 to September 2022 including. The main group: 128 children, who lived in the territory of military operations. Control group: 291 children who lived peaceful territories. The indicators (body mass index, Robinson index, vital index, strength index, V.A. Shapovalova power index and mental capacity of children according to the results of V.Ya. Anfimov correction task) were compared before the start of the developed comprehensive rehabilitation program and 6 months after the start of its implementation.Results. It was found that all elementary school children who lived in locations of military conflict had a decrease in physical and functional parameters of varying degrees of severity, as well as indicators of mental capacity. The comprehensive rehabilitation program promoted to the normalization of the studied indicators in evacuated (57/86, 56%) children in comparison with children who remained in the locations of military operations (43/70, 49%). The studied indicators had the highest recovery rates at the age of 7-8 years. The most vulnerable was a subgroup of 9-10 years old boys who permanently living in conditions of conducting warfare. The development and implementation of the comprehensive integration program using individual rehabilitation routes had an optimizing effect on the studied indicators of physical and functional conditions, as well as cognitive performance in 101 children of the main subgroups, which amounted to 78.9%.Conclusion. Under the influence of the comprehensive integration rehabilitation program, optimization of health indicators was observed in children living in locations of conducting warfare. The most pronounced effect was observed in children who left the territories of shelling as a result of evacuation to Rostov-on-Don.

Assessment of Physical Health of Final-Year Medical Students and Young Doctors

Background: By the end of university, the proportion of medical students with chronic diseases usually increases while physical activity and fitness decrease. Objective: To assess physical development of final-year medical university students and clinical residents. Materials and methods: We have assessed physical health of 16 final-year medical students and 14 first-year medical residents (20.0 % and 25.0 % of the sample population in 2019–2022, respectively). We measured body height, weight, chest circumference, leading hand force, lung capacity, hemodynamic parameters at rest, after exercise and recovery and the mean dynamic pressure in all study participants. We also estimated Quetelet, Pignet, and Robinson indices and those of force, vitality, endurance, and functional changes. In addition, we assessed living conditions, nutrition, and daily energy expenditures of the young people. Results: We established that, under conditions of an organized team, a regulated mode of learning and a high calorie intake, two students (12.5 %) were overweight while the number of overweight residents was six (42.9 %), which was probably related to changes in the lifestyle, nutrition, and daily routine. Estimation of the body mass index showed that 10 (62.5 %) students and 11 (78.6 %) residents were overweight and obese. A more positive body build index among the residents was attributed to a higher number of overweight subjects and confirmed by strength and vital indices and chest circumference measurements. We revealed more considerable preclinical shifts in the health status of the residents in terms of the functional state of the cardiovascular system (diastolic blood pressure at rest and after exercise, heart rate and diastolic blood pressure after exercise, mean dynamic pressure after a period of rest, endurance coefficient, Robinson index) and the index of functional changes. Conclusions: Changes in the synergistic factors of learning and lifestyle of medical residents at the beginning of their professional career cause more significant preclinical alterations in the body compared with students, which necessitates raising their awareness of a healthy lifestyle.

The indices of the cardiovascular system in workers with different body weights in unfavourable working conditions

Introduction. The cardiovascular system is an integral indicator of the body’s adaptive responses.
 Goal is a comparative analysis of the function of the cardiovascular system (CVS) in persons with different nutritional status, working on a rotational basis.
 Materials and methods. Two groups of healthy men were observed: those with normal nutritional status (NNS, n = 14) and those with increased body weight (IBW, n = 13). Working conditions were evaluated according to the degree of harmfulness and danger. The examination was carried out twice: before the start and after 2 months. after shift work. Systolic and diastolic blood pressure, heart rate (HR) were measured. The Robinson index, endurance coefficient, vegetative Kerdo index, and circulatory efficiency coefficient were calculated.
 Results. Working conditions were characterized by work at night in an open area, irregularity of shifts, unregulated breaks for rest, the influence of noise and vibration. In the initial state, body weight in NNS individuals was 74.1±1.1 kg versus 91.8±2.7 kg (p=0.001) in IBW persons; HR – 60.0±2.3 versus 73.1±2.0 (p=0.001). After shift work, body weight decreased by 22.2% and 50.0% in persons in the comparison groups. Integral indicators indicated a more negative response of the cardiovascular system to working conditions in IBW people: less resistance to stress (eurance coefficient), lower performance (efficiency ratio of blood circulation), a higher level of hemodynamic load (Robinson index), in NNS people there were dominated by parasympathetic influences, 33.3% of IBW persons had sympathetic influences.
 Limitations. Healthy males working on a rotational basis, with a normal nutritional status and with overweight and obesity.
 Conclusion. Overweight and obesity negatively affect the cardiovascular system, reducing the functional reserves of the body. Under unfavourable working conditions, the changes are also more pronounced than in the group of people with a normal nutritional status.
