Views on the peculiarities of the creation of educational materials for the development of students of pedagogical specialties of the discipline "Culture of personal health"

The purpose of the study was to clarify the views of the authors on the substantive features of the selection of educational materials in the context of prioritizing their presentation in lecture presentations, to highlight key topics for discussion at seminar classes, and to outline practical tasks for creating pedagogical conditions for the formation of students' competent abilities to use the acquired knowledge in their own life and professional activity. The paper provides a theoretical analysis of the meaningful characteristics of the terms and concepts of the discipline, presents a vision of logical connections between them and the relevance of students' awareness of such dependencies. The results of empirical studies of students' conscious understanding of the essence of concepts are considered, and the authors' vision of the cause-and-effect relationships of false awareness and motivational attitudes to motor activity is illuminated. The novelty of the study should be considered the forms and methods proposed by the authors of introducing educational elements of theoretical familiarization into methodically grounded practical studies of one's own indicators of physical development and the dynamics of functional states in the conditions of extremity of the military state and distance learning. The conclusions point to the understanding of the contents defined by the topic, emphasize the views on the main directions of the selection of educational materials, the development of tools and methods of systematic training of students of the pedagogical profession for the assimilation of knowledge from the educational discipline "Culture of personal health" (in the part of the "Motion Technologies" Program). The authors classified the thematic areas into three groups: General theoretical (definition of terms and concepts and clarification of historical stages of development of the field of "Physical Culture"); Mastering knowledge about the peculiarities of health training and the basics of self-control; Mastering knowledge of methodological features of the organization of motor activity of schoolchildren.

Physical development of adolescents with different levels of motor activity

As part of the study, the physical development of adolescents was evaluated depending on the level of daily motor activity and individual anthropometric indicators of professional athletes. The physical development indicators of 423 boys aged 16 to 18 years were analyzed, which were divided into 3 groups depending on the level of daily physical activity: professional athletes, with additional physical activity, with the usual level of physical activity. The data were collected as a result of a routine medical examination in the period from June to October 2022. The results showed that children aged 16 and 17 with a normal level of motor activity were statistically significantly lower and had less body weight compared to the other groups. The analysis of the fatness index also confirmed the data obtained in the age group of 18‑year-olds. The largest proportion of children (at 16 years — 17.6 %; at 17 years — 33, %) with disharmonious or distinct disharmonious physical development was revealed in the group of children with normal physical activity; no cases of distinct disharmonious level of physical development were found among adolescent athletes. Statistically significant differences in anthropometric indicators among professionally engaged in sports adolescents aged 16 to 18 years were not revealed, while in children with a normal level of physical activity in these age groups, changes in indicators are pronounced, which may indicate an earlier and smoother biological development of adolescent athletes. The use of mass-growth indicators makes it possible to more accurately assess the achieved level of physical development and the level of its harmony.

СОСТОЯНИЕ ЗДОРОВЬЯ НОВОРОЖДЕННЫХ ДЕТЕЙ В СЕМЬЯХ МУЖЧИН ПЕРСОНАЛА АТОМНЫХ СТАНЦИЙ

Purpose: To give a general description of personnel exposure doses and assess the health status of newborn children in families of male nuclear power plants personnel. Material and methods: The work includes the results of studies of the reproductive health of male personnel of Smolensk, Kursk, Kalinin and Novovoronezh NPPs. The source of information on annual doses of occupational exposure of personnel was the data from the Federal Bank of individual exposure doses of personnel of organizations and the population in the territories served by the FMBA of Russia. The state of newborns was assessed by indicators of physical development and the frequency of birth of a child with pathology. Intrauterine growth retardation, congenital malformations, and other perinatal diseases were noted in the structure of pathological conditions. The source of medical data was information from the individual medical records “History of childbirth” and “History of the development of the newborn” for 2007–2018. Results: The health status of newborn children born in 2007–2018 in the families of male personnel of the considered NPPs and in control groups did not differ significantly in terms of selected indicators characterizing the adaptive capabilities of newborn children to extrauterine life. The proportion of healthy children ranged from 60 to 73 % of their total number. In the structure of pathological conditions, perinatal conditions made the greatest contribution (from 10 to 17 %). The birth rate of children with congenital malformations did not exceed 34,0±8,9 per 1000 newborns and was significantly lower than the level adopted by the ICRP for calculating radiation risk (60 per 1000). There were no differences in the influence of the maternal factor (age and complications during pregnancy) on the development of the fetus and the health of newborns in the families of male staff and control groups. According to calculations, the accumulated individual doses of occupational exposure of male personnel before conception of children did not exceed 30 mSv (on average) and for more than 95 % of the personnel – 100 mSv, which is lower than the exposure doses (above 100 mSv) when the negative consequences of exposure of men were reliably observed in the offspring in radiation-epidemiological studies. Conclusion: No influence of occupational exposure on the health status of newborn children in families of male nuclear power plant personnel has been identified. At the same time, it is proposed to conduct monitoring observations of the state of reproductive health of a small group of male personnel of nuclear power plants, whose accumulated effective doses may exceed 100 mSv.

Сравнительный анализ показателей физического развития и физической подготовленности студентов образовательной организации высшего образования различных учебных физкультурных групп в период пандемии COVID-19

The purpose of the study is a comparative analysis of some indicators of physical development and physical fitness of university students of various physical education groups before and after the restrictions of COVID-19. The article presents the experience of monitoring the physical development of higher school students by the Laboratory of Sports and Tourism (LS&T) of the Institute of Physical Culture of Sports and Tourism (IFKSiT) of the Siberian Federal University (SFU).The indicators of physical development and physical fitness of students of 1–3 courses, boys and girls aged 17–22 years of physical education groups: aerobics, basketball and special medical group (SMG) of various institutes of SFU are represented, the analysis shows that these indicators in the groups under study during the predominance of distance learning are insignificantly reduced. The most reduced indicator is the relative strength indicator. The lowest indicators of physical development and physical fitness for all the considered parameters are characteristic of SMG students. The least reduced indicators of physical development and physical fitness were characteristic of the representatives of the aerobics groups, while the flexibility indicator was improved. The current unfavorable epidemiological situation has confirmed the need for the development of various systems for monitoring indicators of physical and functional conditions, physical development, health and physical fitness for higher education, both in the context of the implementation of the subject of physical culture in the educational process and correction of developmental influences during classes, and in the formation of a health-preserving environment of educational institutions.

The Association Between the Maternal Body Mass Index and the Birth Weight of Infants Born

Background: Birth weight is one of the most important and reliable indicators of neonatal survival, physical and mental development of the neonate and is influenced by various factors including genetics, socio-cultural and demographic factors of the mother and one of the most important factors is mother's body mass index (BMI) which directly and indirectly reflects the health and well-being of the mother and her nutritional status. Objectives: The relationship between maternal body mass index and birth weight of neonetes born in hospitals of Islamic Azad University, Tehran Medical Sciences from 2021 to 2022. Methods: In this cross-sectional descriptive study, 288 neonates born in hospitals of Azad University are selected. Information about neonates (gender and birth weight) and maternal information (BMI, age, occupation, education, type of delivery, gestational age, parity and history of preeclampsia) and family income are included in the designed questionnaire. Results: The mean age and BMI of the studied pregnant mothers were 30 and 29, respectively, and the mean weight of the newborns born from these mothers was estimated to be 3200 g. Among the mothers studied, 232 had abnormal body mass index, of which 41% were overweight and about 40% were obese. Among the neonates studied, 25 had abnormal weight, of which 11 were low birth weight and 14 were macrosomic. Analysis of the data of this study showed that maternal BMI can affect pregnancy outcome and birth weight of neonates. Between the mother's BMI and the baby's birth weight, there is a significant relationship. Conclusions: Due to the high mean BMI in pregnant women in this study and the possibility of giving birth to overweight neonate in obese mothers and the complications and risks of macrosomia and the possibility of weight gain and obesity in adulthood, it is necessary to pay attention to overweight pregnant women.

Динаміка показників загальної фізичної підготовленості кваліфікованих армспортсменів

Purpose: article consisted in the study of the dynamics of indicators of general physical fitness among qualified arm sportsmen. Material and methods. Qualified arm wrestlers participating in the arm sports sections in the fitness centers «Tetra», «TRX», «Pheromon» in Kharkov, as well as in the arm sports federation of the Kharkiv region participated in this study. 25 qualified athletes (19-21 years old) of average weight categories (of 70-80 kilograms) who specialize in arm wrestling were involved in the experiment. The study was conducted during the annual macrocycle in a two-year period from 19 to 20 years and 20 to 21 years. Qualified armwrestlers trained according to the classic program developed for the Youth Sports Academy. Results: for absolute values of general physical work capacity of the tested persons, the increase during the whole two-year period was established. However, the value of relative intensity of increase of absolute values of general physical work capacity at the stages of observations is different. Thus, the results of comparison of indicators of a run on 100 m in the period from 19 to 20 years old made (t=1,11; p>0,05), from 20 to 21 years old (t=1,06; p>0,05), for all time of researches the result (t=1,94; p>0,05), low results testify that a run on 100 m is not a specific exercise for armwrestlers. Comparison of results of long jumps from a place: from 19 to 20 years old (t=0,99; p>0,05), from 20 to 21 years old less significant changes (t=0,89; p>0,05), for two years made (t=2,25; p<0,05) that is a reliably better result and testifies that jumping exercises are not specific for armwrestling. In a pull-up on a crossbar from 19 to 20 years old (t=1,35; p>0,05), from 20 to 21 years old (t=0,94; p>0,05), for two years (t=2,33; p<0,05), it is the best indicator and testifies that armwrestlers have well-developed muscles of the upper extremities which in turn influence on correctness of the exercise of pulling up on a crossbar. Comparison of results of bending and extension of hands in a support lying on a floor made from 19 to 20 years old (t=1,00; p>0,05), from 20 to 21 years old more significant changes were received (t=1,92; p>0,05), and for two years the result made (t=2,66; p<0,05) that is a reliably better result. Comparison of results of a lunge on a crossbar, arms bent at an angle of 90 degrees, made from 19 to 20 years old (t=2,02; p>0,05), in the following year from 20 to 21 years old the significant increase in reliability in results (t=2,29; p<0,05) was received. In two years the increase of result was (t=4,75; p<0,001) that is a high reliable result and testifies that static exercises for armwrestling are the main and they need to be improved from year to year. Conclusions. The revealed differences in the intensity of growth of physical development indicators over the two-year observation period reflect unevenness. Even in such a relatively short period of time (two years) there is a noticeable difference in the intensity of growth of most of the studied indicators of physical development. Thus, the results which characterize age dynamics of indicators of the general physical fitness of skilled armwrestlers of 19-21 years old, testify that the greatest rates of growth on all indicators are observed during three years of training, but only from 19 to 21 years old indicators were reliable, however the value of relative intensity of growth of absolute values of the general physical work capacity at stages of observations is different.

Evaluation of indicators of physical development and quality of life of students of M. K. Ammosov North-Eastern Federal University

The aim was to evaluate the indicators of physical development and quality of life in students of M.K. Ammosov North-Eastern Federal University (NEFU).Material and methods. The study involved 755 students of NEFU. at the age of 17–20, Mongoloid and Europeoid races, among which there were 273 (36.16%) girls and 482 (63.84%) boys. The studies were conducted on the basis of voluntary informed written consent. The survey included the determination of anthropometric parameters, assessment of the quality of life and questionnaires. Identification of the main characteristics of students' health was carried out through a medical examination.Results. An analysis of morphological indicators revealed differences in the physical development of students of the Mongoloid and Europeoid races of the Republic of Sakha (Yakutia). In the analyzed groups, there were significant differences in body length depending on race. The highest indicators of body length are determined in persons of the Europeoid race, the smallest values - in students of the Mongoloid race. The study of quality of life indicators found a decrease in the psychological component of health among the respondents, due to the lack of readiness of the components of the professional and personal perspective and the inability to carry out psychological regulation of their behavior, which serves as an obstacle to their adaptation to independent living. At the same time, the indicators of the physical component of the health of the examined students remain, in most cases, within the normal range.Conclusion. Analysis of the results of the study of the physical development of NEFU students indicates that representatives of the Mongoloid race living in the territory of Yakutia are characterized by growth below average, low density, and a small body surface area compared to representatives of the Europeoid race. The level of physical development in most of the examined persons is assessed as average, and in 37.2% of students the functional state of the circulatory system is characterized by tension in the mechanisms of adaptation, which may be due to the adaptation of the body to new living conditions.

Comparative assessment of physical development indicators of pupils in general education schools with different types of food service operation

Objective. To carry out a comparative assessment of physical development indexes of pupils of general education schools with hot meals and a buffet type of catering.Materials and methods. There were examined 432 schoolchildren from 7 to 15 years old, divided into two groups: group 1 – pupils of general education schools in which there were canteens based on food raw materials and semifinished products; group 2 – pupils of general education schools with a buffet with implementation of ready meals, confectionery, drinks, etc. To study the main indexes of physical development somatometric research methods were used. Differences at p≤0,05 were considered statistically significant.Results. The absence of hot meal service contributes to an increase in the number of children with body length below average in 2.3-15.7 times (among girls aged 11-15 – p<0.001); with excess body weight – 1.2-5 times (among boys aged 7-10 – p<0.01), with reduced body weight – 1.4-1.7 times; with increased and excessive nutrition – 1.3-11.6 times (among boys - p<0.05-0.001, and among girls – p<0.05). Consequently, the absence of hot meal service in general education schools affects the indicators of the physical development of children: deviations from the mean values in body length being more frequently observed in girls, and in body weight in boys.Conclusion. The absence of hot meal service in education institutions negatively affects the physical development of students. For the harmonious development of children, the formation of hygienic skills of healthy eating and a conscious attitude to the choice of a proper diet, it is necessary to organize hot school meals and strengthen sanitary and educational work.

Конституциональные особенности состояния здоровья детей дошкольного возраста с рецидивирующей респираторной патологией

The purpose — to study the constitutional features of physical and neuropsychic development of 4–7 year old children of intro- and extravert types with chronic adenoiditis. Material and methods. The study included preschool children with a verified diagnosis of chronic adenoiditis. The control group consisted of conditionally healthy children without chronic diseases. All children were divided into introverts and extraverts. The features of somatometric and somatoscopic indicators of physical development, emotional, characterological and intellectual indicators of neuropsychic development and socialization were studied. Results. For introverted children with chronic adenoiditis, the disease onset occurred at the age of 3–4 years; obstructive sleep apnea syndrome in combination with snoring prevailed; the duration was about a year and a half; frequent acute purulent otitis media with a long monotonous course, the manifestation of excessive vagotonia and pronounced disorders of sound reproduction were observed. In extroverted children, chronic adenoiditis debuted at the age of 4–5 years, in the form of postnasal syndrome with night cough, excessive sympathicotonia and with earlier formation of exudative otitis and hearing loss; the duration of the disease was about six months. Introverts with chronic adenoiditis were three times more likely than healthy children of this type to have body mass deficiency and microsomia, lower indicators of social activity, abstract thinking, attention, fine motor skills and semantic memory. In extroverts with chronic adenoiditis, among the variants of physical development disorders, the frequency of excess body weight and macrosomia doubled, the level of impulsivity increased, discipline, large-motor giftedness, conceptual and visual-imaginative thinking decreased. Conclusion. Clinical and functional differences in the course of chronic adenoiditis in children of intro- and extravert types and the identified features of their physical and neuropsychic development can be the basis for creating differentiated programs for their medical and social support on an outpatient basis. The constitutional approach makes it possible to assess the psychophysiological features of individual qualities that make up the «ground» of the disease, both to make a reasonable choice of an effective combination of health disorders correction and prevention methods, and to ensure the fullest realization of a child’s physical and social potential.

DIFFERENTIATED APPROACH IN THE ORGANIZATION OF PREVENTIVE AND HEALTHY ACTIVITIES WITH PEOPLE OF MATURE AGE TAKING INTO ACCOUNT MORPHO-FUNCTIONAL AND BIOMECHANICAL INDICATORS

The assessment of the physical development of the participants of the pedagogical experiment shows that in most of the examined women (76.1%; n=35), the ratio of body mass and length was within the normal range. Among the examined, women with harmonious physical development predominated (84.8%; n=39). Instead, the studied contingent that was prone to posture disorders (76.1%; n=35), was characterized by average physical fitness indicators and insufficient duration of motor activity at medium and high levels. Analysis of the factorial structure of indicators of physical development, physical fitness and motor activity of women of the first mature age made it possible to determine the leading factors that ensure the optimization of physical culture and health activities of the specified contingent, including indicators of the functional state of the musculoskeletal system (power endurance of various muscle groups), the component composition of the body, the posture of women, and the integral indicator is the body type.

Effect of intensive functional training on indicators of cadets’ physical state

The article is devoted to the study of the influence of high-intensity functional training according to the "Crossfit" system on indicators of physical development and functional capabilities of cadets who are future officers of the Airborne Assault Forces of the Armed Forces of Ukraine during the training process. The study was conducted at the Military Academy (Odesa, Ukraine) at the Airborne Assault Troops Specialist Training Faculty in 2020-2021. 256 male cadets took part in the study. Two groups were formed: Group 1 (n=40), whose cadets during their training worked out in the crossfit section of the academy, and Group 2 (t=216), whose cadets worked out according to the current system of physical training at the academy and did not additionally attend any of the sports sections. The physical state of the cadets was assessed according to the indicators: body length, body weight, hand dynamometry, heart rate, blood pressure, lungs capacity, as well as according to the calculated indices. A positive effect of high-intensity functional training according to the "Crossfit" system on indicators of cadets’ physical state, especially in the 3rd and 4th years of training, has been established. The most pronounced effect of functional training was found in the indicators of the cardiovascular system, body weight, and cadets’ strength qualities. This allows us to assert that the high level of cadets’ physical state will contribute to the improvement of the effectiveness of the tasks assigned in the course of their future military and professional activities.

FACTORS THAT ENSURE AN ADEQUATE LEVEL OF PHYSICAL FITNESS IN FEMALE STUDENTS OF HIGHER EDUCATION INSTITUTIONS

The article discusses the factors that ensure the appropriate level. It was determined that physical capacity is the maximum mechanical work that a person is able to perform. Assessment of a person's physical capacity is necessary for solving a wide range of practical problems: determining the state of health, the results of sports training, and others.
 It has been proven that physical performance depends on many factors: body composition and anthropometric indicators, muscle strength and endurance, the state of the musculoskeletal system, functional and endocrine systems. Factors such as energy potential, completeness of its use and cost-effectiveness of movements are also important. It has been established that work capacity is ensured by both aerobic and anaerobic processes of energy generation, and according to the preference of one of them, aerobic physical work capacity, anaerobic and mixed are distinguished.
 Despite the fact that the indicators of physical development of student youth show positive dynamics, the general state of health of modern youth is deteriorating, which negatively affects their physical and mental capacity. The most acute social problem in Ukraine is the deterioration of the health of children and youth. Negative factors that reduce the level of health are improper nutrition, hypokinesia, psycho-emotional overstrain, and bad habits.
 Effective means of improving not only physical, but also emotional health of a person include aqua fitness. Nowadays, there is no doubt about the possibility of a positive effect of physical exercises in water on the state of physical and mental health, improving the activity of the cardiovascular, respiratory, and hormonal systems and developing the physical qualities of a person.

Features of the clinical course of pregnancy, childbirth and the condition of newborns in women with HCV infection

The objective: to conduct a retrospective clinical and statistical analysis of the pregnancy course, childbirth and the condition of newborns in women with HCV infection.Materials and methods. A retrospective clinical and statistical analysis of the pregnancy course, childbirth and the condition of newborns was carried out according to the data of 351 birth histories of women with HCV infection based on the materials of the archive of the communal non-commercial enterprise “Kyiv Municipal Center of Reproductive and Perinatal Medicine” for the period from 2016 to 2021. The control group (CG) included 50 healthy pregnant women. Statistical processing of research results was carried out using standard programs “Microsoft Excel 5.0” and “Statistica 8.0”. Results. In women with HCV infection compared to the group of healthy pregnant women a significantly high frequency (p<0.001) of such pregnancy complications was found: threat of pregnancy interruption – 64 (18.2 %) patients versus 2 (4.0 %) persons, edema of pregnant women – 72 (20.5 %) and 4 (8.0 %), respectively; preeclampsia – 45 (12.8 %) versus 2 (4.0 %), gestational anemia – 131 (37.3 %) versus 6 (12.0 %), as well as placental insufficiency with fetal growth retardation syndrome (FGR) – 69 (19.6 %) versus 3 (6.0 %; p<0.05) and intrahepatic cholestasis of pregnant women – 42 (11.9 %) versus 1 (2.0 %; p<0.05). In 73 (20.8 %) pregnant women with HCV infection the childbirth was complicated by premature rupture of the membranes, of which almost half of the cases (42 (11.9 %) of the patients) finished with premature birth, while in CG only some women had such complications. Fetal distress during childbirth was reliably detected more often in pregnant women with HCV infection than in CG women (χ2=4.76; p=0.024). Caesarean section was performed in 86 (24.5 %) patients with HCV infection versus 2 (4.0 %) persons in CG (p<0.001).The newborns from mothers with HCV infection had lower indicators of physical development and decreased Apgar score assessment, increased frequency of conjugation jaundice.Conclusions. Pregnant women with HCV infection are characterized by a significant increase in the number of pregnancy complications, such as the threat of pregnancy interruption, the threat of premature birth, gestational anemia, placental dysfunction, fetal growth retardation syndrome, and preeclampsia; during childbirth – premature and antepartum rupture of amniotic membranes, premature birth, weakness of uterine activity in labor, increased blood loss. The condition of newborns from women with HCV infection is characterized by a significant increase in the frequency of asphyxia during childbirth, CNS hypoxic-ischemic damage, prematurity and conjugation jaundice.

Тілобудова кваліфікованих воротарів і польових футболістів

The purpose of the study was to determine the indicators of physical development and body composition of goalkeepers and outfield football players. Materials and methods. 34 football players of the Ukrainian Premier League took part in the research, including: 11 goalkeepers and 23 outfield players. The following research methods were used: generalization of data from scientific and methodical literature, pedagogical observations, medical and biological methods (anthropometry, caliperometry); methods of mathematical statistics. Results and discussion. Anthropometric measurement was carried out according to 23 indicators and the composition of football players – according to 3 indicators. The most significant difference between goalkeepers and outfield players was determined by indicators of body weight, body length and body circumferences: wrist, forearm, shoulder at rest and tension, neck, hips. Thus, the body weight index of goalkeepers was 82.9 ± 5.8 kg, and outfield players – 69.1 ± 7.0 kg; the body length index of goalkeepers was 192.2 ± 5.1 cm, and that of outfield players was 179.2 ± 6.5 cm. That is, goalkeepers are taller compared to outfield players and mostly have a larger body mass. In addition, goalkeepers are stronger and stockier than outfield players in terms of parameters. Also, the indicators of skin-fat folds were significantly different, according to the playing role of footballers (p <0.001). It was found that goalkeepers are larger in terms of the volumes in the chest, waist and skin-fat folds in the area of the lumbar region of the back. A slight difference (14%, p <0.05) was found between goalkeepers and outfield players in the indicator of the skin-fat folds of the triceps muscle. A factor analysis of the obtained results of physical development was also carried out. The purpose of this analysis was to identify the generalized anthropometric characteristics and body composition of football players of various playing roles. Conclusion. For further consideration of the received information by the value of eigenvalues that had an indicator of at least 1, four informative factors were noted: factor 1 (7.99), factor 2 (2.24), factor 3 (1.58) and factor 4 (1.12). According to the relative contribution to the total variation, which should have been more than 10%, two informative factors were identified: factor 1 – 47.0%, factor 2 – 13.2%. It was possible to identify the following most important indicators for this group of factors: body weight, body length, circumferences: forearm, shoulder at rest, neck, waist, hips, lower legs; skin-fat folds: oblique abdominal muscle, biceps brachii, thigh, triceps brachii, lumbar back; composition of the body – "net mass". In the future, the results obtained in this way will allow coaches to make adjustments to the educational and training process to improve the physical and functional fitness of football players

Physical Development at School Entry in Children with Congenital Hypothyroidism Diagnosed by the National Program of Newborn Screening in Iran.

The newborn screening program for diagnosing and treating children with congenital hypothyroidism (CH) in Iran was established in 2004. This study aimed to evaluate the national program's success in maintaining the physical development and anthropometric indexes of children with CH. This historical cohort study was carried out in five provinces located in five different geographical regions of Iran. The anthropometric indexes, including weight, height, and head circumference of 240 children diagnosed with transient congenital hypothyroidism (TCH) (n = 131) and permanent congenital hypothyroidism (PCH) (n = 109) were measured and compared with those of 240 healthy children aged six. Mean ± standard deviation (SD) of weight, height, and head circumference of children with CH aged six were 20304.8 ± 4457.9 g, 115.6 ± 5.9 cm, and 50.8 ± 1.7 cm, respectively. Mean ± SD of height (116.7 ± 6.1 cm) and head circumference (51.1 ± 1.7 cm) in the control (healthy) group were significantly higher than those of the CH children group (P < 0.05). Mean ± SD weight in the control group (20741.2 ± 4337.3 g) was higher than that in the CH group (20304.8 ± 4457.9 g). However, the difference was not statistically significant (P = 0.3). No significant difference was observed between TCH and PCH children in the subgroup analysis (P > 0.05). Although the mean of anthropometric indexes in CH patients was slightly lower than that in healthy children aged six, the difference between the two groups was insignificant. The physical development of children with CH was evaluated as good. Our results suggested that the newborn screening program for identifying and treating children with CH in Iran may have improved the growth outcomes.

Analysis of the dynamics of physical development of cadets as a result of the application of crossfit equipment

Purpose: to investigate the impact of classes in the program of physical training of cadets of military institutions of higher education at the stage of primary training with the use of crossfit tools on the physical development of cadets. Material &amp; Methods: was organized and conducted. anthropometric study and calculation of indices of physical development of cadets. The study was conducted in the sanitary section of the National Academy of Ground Forces named after Hetman Petro Sahaidachny by medical personnel 30 minutes after the ascent. Results: it was determined that conducting training sessions using crossfit equipment has a positive effect on strengthening the musculoskeletal system of cadets and improving their muscular system (especially the muscles of the back, legs and shoulder girdle). During the study of body weight, there were positive changes in the direction of weight reduction by 3.62 kg (t=2.52; p&lt;0.05) at the end of the experiment; the average value of VL in EG improved compared to the initial data by 245.48 ml (p&lt;0.001), and in EC – by 78.22 ml (p&lt;0.05); the difference between the dynamometry indicators of the left and right hand of the EG at the first and fifth stages of the study was 3.18 kgc and had positive significant changes (t=3.18; p&lt;0.01), the difference between the dynamometry indicators of the left and right hand of the CG was 2.19 kgf and had positive unreliable changes (t=1.85; p&gt;0.05). As a result of the pedagogical experiment, it was determined that the dynamometry indicators of the right and left hands of EG and CG cadets at the end of the experiment differ significantly (p&lt;0.01), which indicates the effectiveness of the physical training program. The chest circumference of the cadets at the beginning and at the end of the experiment has reliably stable results and is only 2.04 cm (p&gt;0.05) and are reliable. As for the Quetelet index, there were positive changes towards improvement, namely: at the beginning of the experiment it was 4.85 g/cm (t=0.69; p&gt;0.05), at the end – 25.80 g/cm (t=4.09; p&lt;0.001), which emphasizes the positive impact of exercise and crossfit. Conclusions: it has been proven that the application of a physical training program at the stage of primary training with the use of crossfit equipment ensures the positive development and strengthening of the musculoskeletal system of cadets, the improvement of their muscular system. Under the influence of systematic crossfit classes, the VL increases, the circumferences of the chest and shoulders increase, the volume of the waist decreases, and body weight stabilizes. These circumstances have a positive effect on the work capacity of cadets, improve their physical health, improve their well-being and increase their work efficiency.

Justification of the Selection Techniques in Martial Arts using Wald's Sequential Analysis

The study purpose was to develop a selection technique in martial arts based on indices of physical development using Wald's sequential analysis.&#x0D; Materials and methods. 12 anthropometric indicators were determined. 9 indexes of physical development were calculated on their basis. 16 elite athletes (candidates for masters and masters of sports) were divided into two groups. Group 1 included 7 athletes (judo, sambo, Greco-Roman and freestyle wrestling) aged 18.43±0.43. Group 2 included 9 kickboxing athletes aged 18.22±0.52.&#x0D; Results. A prognostic table containing indices of physical development has been developed. The informativeness of the indicators varied within 296.15–1.73. The content of the prognosis consists of evaluating the results, determining the corresponding coefficients and summing these coefficients until one of the prognostic thresholds is reached. In accordance with generally accepted approaches, the value of the thresholds was set at the level of ±13, which corresponds to a probability of 95% (p&lt;0.05). Exceeding the positive threshold improves an athlete's prospects in wrestling. Achieving a negative threshold corresponds to a perspective in kickboxing.&#x0D; Conclusions. The conducted research made it possible to justify and develop a method for selecting martial arts athletes using indices of physical development. The proposed technique is based on Wald's sequential analysis and is a simple, informative and objective tool for the selection and prognosis of athletes' condition.

Special physical fitness factors of athletes involved in pole sports

Purpose: to determine the peculiarities of training female athletes engaged in Pole Sports on the basis of the factor analysis of physical, special physical qualities and functional capabilities.&#x0D; Material and methods: the study involved 15 female athletes (age 12-13 years), who are engaged in the sports club "Atmosphere" in Pole Sport and aerial acrobatics, Kharkov. Athletes are in the group of initial training (amateur level) and have the experience of sports activity 1-1,5 years. The study was conducted in September 2021. All participants and their parents agreed to participate in the experiment. Methods: theoretical analysis of literary sources; methods of testing physical development (height, weight); physical fitness (Push-ups 30 s, jumping rope for 3 min, lifting the trunk in sitting position in 1 minute, dynamometry of right and left arms, tilt of the body forward from the sitting position); special physical condition (chopper, pulling up on the pole, jumping rope for 3 min, jumping " Heels back", jumps with turning 180°, jumps with turning 360°, jumping into grouping); methods of functional capabilities (Genchi and Ruffier tests), mathematical and statistical methods using "EXCEL" and "SPSS" computer programs (factor analysis by principal component method was used). Results. A factor analysis of physical development indicators, physical training, functional athletes specializing in Pole Sport. It was found that in the structure of preparation of the athletes of this group overcomes the first factor "Special endurance" (15,21% of the total total dispersion), then the second "Functional abilities" (14,54% of the total total dispersion), the third factor "Power capabilities" (14,12% of the total cumulative variance) and the fourth factor " Coordination abilities" (14,02% of the total cumulative variance), the fifth factor " Flexibility " (13,52% of the total cumulative variance), the sixth factor "Technical capabilities" (12.37% of the total cumulative variance). The percentage contribution of these factors indicates the equivalent importance of these factors.&#x0D; Conclusions. The training means for the development of special physical qualities and techniques, the dosage of the volume and intensity of loads for athletes 12-13 years old involved in Pole Sports are presented.

Correction system effectiveness of the children physical development of early and younger preschool age with psychomotor disorders (on the example of posture)

Purpose: to reveal the reliability of the effectiveness of the developed author's system for correcting the physical development of young and preschool children with psychomotor disorders.&#x0D; Material and methods. A total of 208 children of early (2-3 years) and younger preschool (3-4 years) age with psychomotor disorders took part in the study. Specially organized studies of the effectiveness of the system of corrective physical education for children of early and younger preschool age with psychomotor disorders were conducted during 2019 - 2021. They took place in specialized preschool education institutions, as well as kindergartens of the combined type in the city of Odesa, Odesa region, as well as in the cities of Kramatorsk, Kharkiv, Mykolaiv, Balaklia (Kharkiv region). I also summarized my own long-term (over 25 years) experience of individual rehabilitation activities with the specified contingent of children in the Odessa Movement Rehabilitation Center. All children were divided into two groups: 108 from experimental groups and 100 from control groups.&#x0D; Results. Summarizing the analysis of the results of the dynamics of physical development indicators of children with psychomotor disorders (on the example of the study of their posture), we should conclude that almost all the indicators of children from the experimental groups had a marked improvement in results, which in the absolute majority of cases was confirmed statistically (P&lt;0,01‒0,05). Children from control groups also demonstrated some improvement of physical development indicators, but it was by no means confirmed by the methods of mathematical statistics (P&gt;0,05).&#x0D; Conclusions: the conducted formative pedagogical experiment confirmed the reliability of the effectiveness of the developed author's system of correction of physical development of children of early and early preschool age with psychomotor disorders in comparison with the traditional system of their education.

Region-related patterns of the main physical development indicators observed in northerners in the ontogenetic aspect

Indicators of physical development appear to be environmentally sensitive and thus we can consider them the main characteristics of the population health.The aim. To assess the line of physical development main variables in the ontogenetic aspect (data from the North born male subjects aged from 8 to 77).Material and methods. Three thousand seven hundred and ninety-four male Caucasians from 17 age groups were examined to analyse their physical development.Results. The study showed longer body length variables as the region-related somatometric picture which is characteristic of male Caucasian northerners in comparison with those from other regions of the Russian Federation, as well as from other countries. Besides, they exhibited significantly lower body mass index and reported to have had lower body weight since the age of 17. We can see the modern northerners’ somatotype being influenced by regional extremes. That also includes the end of the body growth processes by the start of ontogenesis in the youth. The line pattern of annual growth observed in the body length and weight variables indicates a combined pronounced dynamics in the 11 to 16 age period. By the age of 60–77 years subjects tend to decrease in the body length with a significant increase in the body weight and body mass index by the age of 31–36.Conclusion. The study suggests that identifying risks for the development of noninfectious and cardiovascular diseases caused by accelerated BMI in older populations requires monitoring of the North inhabitants’ main physical development indicators as well as the body annual growth variables.
