The aim of the study - to analyze the content of the muscular component of the body in girls of 16-20 years old belonging to different constitutional groups. Material and methods. 729 girls (400 at the age of 16-17 years, and 329 at the age of 18-20 years) were explored by the method of complex anthropometry and bioimpedance. Statistical processing of digital materials was to calculate the arithmetic mean values, their errors. The evaluation of the reliability of differences in arithmetic mean values was carried out by the method of confidence intervals. Results. Girls of leptosomic groups of the constitutions are identified in 20.5% of cases, mesosomic group - in 34,2% of cases, megalosomic group at 35,7% of cases, the indeterminate group and in 9,6% of cases. The obtained data on the content of muscle mass indicate that the studied indicators significantly depend on the belonging of girls to a particular constitutional group. The absolute content of muscular components of the girls of leptosomic group of the constitution is substantially less than women of other constitutional groups. Conclusion. The study received a quantitative of girls of different constitutional groups in the studied population; obtained data on the characteristics of the absolute and the percentage of muscular component of the body depending on the type of constitution, allow us to conclude about the individual variability of the severity of these indicators and the data obtained can be used to create the passport's physical development in contemporary conditions.

The aim of the study was to investigate the content of the muscular component of the body in girls, aged 16–20, with different somatotypes.Material and methods. The study included 500 females, aged 16–20, representatives of the Slavic ethnic group, residents of Moscow and the Moscow region. They were divided into two groups: 16–17 and 18–20 years old (250 girls in each group). The diameter of the wrist and ankle, wrist and calf circumferences (mm), thickness of the dermal-fat fold of the back, shoulder, abdomen and thigh (using a calipometry method) were calculated in girls of all groups. The content of the muscular component of the soma was also calculated by bioimpedansometry (using a Russian device "ABC-01 Медасс"). Statistical processing of findings included calculation of their arithmetic mean values, errors. The significance of differences was determined using parametric and nonparametric criteria (Student and Fisher criteria) depending on the type of distribution in the sample.Results. Heterogeneity of the population was revealed when determining a somatotype: inclusion into a particular constitutional group insignificantly modifies with the transition from 16–17 to 18–20 years of age. Mesosomy was a predominant feature in girls of both age groups (48% of all studied girls aged 16–17 and 40.0% of all studied girls aged 18–20). Girls with megalosomal body type constituted 24.0 and 26.5%, respectively; girls with leptosomal body type constituted 20% in all age groups; girls with undefined body type constituted 8.0% and 13.5%, respectively. The content of the muscular component of the soma demonstrated significant constitutional differences between these parameters. In comparison of the studied groups, there was an insignificant increase in the absolute indices of the muscle component with a decrease in the relative indices - the mass of the muscle component to body weight – with increasing age.Conclusion. The data obtained demonstrate significant constitutional features of the absolute and relative (percentage) content of the muscle component of the body as an important aspect of the female physical status. This information is relevant for both theoretical and practical medicine.

Abstract In the presented text the author points out to anthropological as well as axiological foundations of the boxing fight from the viewpoint of Hegel’s philosophy. In the genial idealist’s views it is possible to perceive the appreciation of the body, which constitutes a necessary basis for the man’s physical activity, for his work oriented towards the self-transformation and the transformation of the external world, as well as for rivalry and the hand-to-hand fight. While focusing our attention on the issue of rivalry and on the situation of the fight - and regarding it from the viewpoint of the master - slave theory (included in the phenomenology of spirit), it is possible to proclaim that even a conventionalised boxing fight - that is, restricted by cultural and sports rules of the game - has features of the fight to the death between two Hegelian forms of selfknowledge striving for self-affirmation and self-realisation. In the boxing fight, similarly as in the above mentioned Hegelian theory, a problem of work and of the development of the human individual (that is, of the subject, self-knowledge, the participant of the fight) appears. There appears also a prospect of death as a possible end of merciless rivalry. The fight revalues the human way in an important way, whereas the prospect for death, the awareness of its proximity, the feeling that its close and possible, saturates the life with additional values. It places the boxer, just like every subject fighting in a similar or a different way, on the path towards absolute abstraction - that is, it brings him closer to his self-fulfilment in the Absolute, to the absolute synthesis. The Hegelian viewpoint enables also to appreciate the boxing fight as a manifestation of low culture (being in contrast with high culture), to turn attention to the relations which - according to Hegel - take place between the Absolute and the man, as well as to show which place is occupied by the subject both in the process of the Absolute’s self-realisation and in the German thinker’s philosophical system. Independently of the dialectical, simultaneously pessimistic and optimistic overtone of considerations connected with the very boxing fight (regarding destruction and spiritualisation on a higher level), it is possible to perceive farreaching appreciation of the human individual in Hegel’s philosophy since the Absolute cannot make its own self-affirmation without the individual, without the human body, without the fight aimed at the destruction of the enemy and without the subjective consciousness and the collective consciousness which appear thanks to this fight. Thus, it is justified to suppose that the foundation of the whole Hegel’s philosophy is constituted by anthropology and that in the framework of this anthropology a special role is played by the fight and by work, which changes the subject and his(her) environment. Admittedly Hegel does not emphasise it explicitly, nevertheless his views (with their centre, which, according to Hegel himself and his interpreters, is constituted by the Absolute) have, as a matter of fact, an anthropocentric character and the main source of the subject’s development is the struggle which, irrespectively of its result, always primarily leads to the destruction or even to the death of one of the sides, just like in the boxing fight. However, it is also a germ of the positive re-orientation of the subject, the beginning and a continuation of that what the phenomenology of the spirit describes as a movement towards absolute abstraction.

The influence of a change in nutrition on the oral microbiota are discussed in literature, but usually only changes of population mean values are reported. This paper introduces simple methods to also analyse and report the variability of patients’ reactions considering data from the culture analysis of oral biofilm. The framework was illustrated by an experimental study exposing eleven participants to different nutrition schemes in five consecutive phases. Substantial inter-individual variations in the individual reactions were observed. A new coherence index made it possible to identify 14 instances where the direction of individual changes tended to coincide with the direction of the mean change with more than 95% probability. The heterogeneity in variability across different bacteria species was limited. This allowed us to develop recommendations for sample sizes in future studies. For studies measuring the concentration change of bacteria as a reaction to nutrition change, the use of replications and analysis of the variability is recommended. In order to detect moderate effects of a change in nutrition on the concentration of single bacterial taxa, 30 participants with three repetitions are often adequate. Insights into the relationship between nutrition and the microbial composition can be helpful for the development of dietary habits that promote the establishment of a healthy microbial flora and can therefore prevent the initiation of oral diseases such as caries and periodontitis.

In nowadays, an important area in medicine is the early preclinical identification of the parameters deviations from the norm, where mathematical modeling can help, which should be used to calculate individual linear parameters of internal structures based on external parameters of the body. The aim of the study was to calculate the individual total linear measures of the lumbar intervertebral discs in juniors and men of the first adulthood (17-28 years) in norm. The total size of the each intervertebral discs were calculated a sum of the anterior-posterior diameter, frontal diameter and vertical sizes of each lumbar intervertebral discs, which were measured by MRI. The next step was to calculate the relative proportional nonlinear somato-disc rates (based on body weight and body length) for each individual examined. Mathematical processing of the measured parameters and the relative values of the somato-disc relationships was carried out by the statistical data processing program “STATISTICA 6.1” using parametric methods. The correct distribution of the variational series indicators, mean values and their standard errors were evaluated. Based on relative values the mathematical model was created to obtain individual values of the TS of the lumbar intervertebral discs. Subsequently, we compared the measured total discs sizes of the anterior-posterior, frontal diameters and vertical sizes of the lumbar intervertebral discs with a mathematically calculated value for each lumbar intervertebral discs. The significant difference between the mathematically calculated and measured values of the total intervertebral discs’ sizes of the didn’t exceed 10%. Determination of the standard linear dimensions of the intervertebral discs of the lumbar spine using CT and MRI and comparison with theoretically calculated indices will make it possible to diagnose early manifestations of the lumbar intervertebral discs pathology.

?MUSCULAR CHRISTIANITY? was a system which relied upon sport to allow people to grow in a moral and spiritual way along with their physical development. It was thought that . . . in the playing field boys acquire virtues which no books can give them; not merely daring and endurance, but, better still temper, self restraint, fairness, honor, unenvious approbation of another?s success, and all that ?give and take? of life which stand a man in good stead when he goes forth into the world, and without which, indeed, his success is always maimed and partial [Kingsley cited from Haley, in Watson et al].1 This system of thought held that a man?s body is given him to be trained and brought into subjection and then used for the protection of the weak, the advancement of all righteous causes [Hughes, cited in Watson et al].1 The body . . . [is] . . . a vehicle by which through gesture the soul could speak [Blooomfield, cited in Watson et al].1 In the 1800s there was a strong alignment of Muscular Christianity and the game of Rugby: If the Muscular Christians and their disciples in the public schools, given sufficient wit, had been asked to invent a game that exhausted boys before they could fall victims to vice and idleness, which at the same time instilled the manly virtues of absorbing and inflicting pain in about equal proportions, which elevated the team above the individual, which bred courage, loyalty and discipline, which as yet had no taint of professionalism and which, as an added bonus, occupied 30 boys at a time instead of a mere twenty two, it is probably something like rugby that they would have devised. [Dobbs, cited in Watson et al]1 The idea of Muscular Christianity came from the Greek ideals of athleticism that comprise the development of an excellent mind contained within an excellent body. Plato stated that one must avoid exercising either the mind or body without the other to preserve an equal and healthy balance between the two.

Important research task is to find the integral criterion of rapid assessment the person's functional state and its current changes. Used for this purpose, the traditional methods do not always provide a complete and easy-to-interpret description of this subject. The methods of determining the functional state by a measuring skin conductance and existing rules for processing the results are considered here. Is illustrated a strategy for determining the functional state by electrocutaneous characteristics of acupuncture points, or micro-zones.<p>The investigation of human functional state by measuring the electrocutaneous characteristics of micro-zones led to the discovery of the phenomenon of the stability of the average value of the conductivity in electrodermal acupuncture “meridians source-point”. Mutual relations between the average values of the individual electrocutaneous characteristics in micro-zones turned out to be a stable and persist over time. Electrocutaneous characteristics of micro-zones reflect the current functional state of a person, so their measurement can be used to find the relative change in the condition of the person in the course of any activity.<br />The functional state of a person depends on the season, the degree of fatigue, has gender differences.<br />The proposed method of processing the measurements of the electrocutaneous characteristics in micro-zones has novelty; it allows determining the relative changes in the status of the body individual systems, and to carry out the quantitative calculations of such changes.<br />Given the non-chaotic mutual relative distribution of electrocutaneous characteristics of micro-zones mean values, we can assume that the micro-zones actually exist; each of them has some informative parameters (like the teeth of the ECG) and are functional reflections of skin -and- visceral connections. Probably it is a representation of one more regulatory system of an organism.</p>

Background: Diabetes mellitus being a metabolic disorder lot of alteration takes place in body composition parameters such increase in fat mass, decrease in muscle mass, increase visceral fat. With advancing age, the predominant feature develops which is more prevalent in diabetes. These changes in body composition should be monitored. The changes if monitored at an early age, can be well managed and proper interventions can be developed.  The study was conducted to observe the changes taking place in the body composition parameters in individuals with type II diabetes with varied duration of the disease.Methods: This cross- sectional study was done in 228 type II diabetic subjects from the clinics of the Mumbai and Pune. The baseline data was collected from the all the subjects coming to the clinic through the general questionnaire, Anthropometric measurements and Body composition analysis was done by the BIA principle-based Analyser.  Then these subjects were distributed according to the duration of the disease and then analysed.  The data was analysed using SPSS version 22 and mean values p values were obtained.Results: The results showed that there is statistically significant increase in fat mass, visceral fat and decrease in muscle mass.Conclusions: There is change in body composition parameters like decrease in muscle mass, increase in fat and visceral fat along with the increase in the duration of the disease.

Background: Bioelectrical impedance analysis (BIA) is a simple and rapid technique to measure body composition (BC). Validity of BIA in patients with low body mass index (BMI) remains controversial. We assessed the validity of several BIA equations to evaluate fat-free mass (FFM), fat mass (FM) and muscle mass in patients with anorexia nervosa (AN) by using dual X ray absorptiometry (DXA) as reference. Methods: Sixteen BIA equations developed for FFM and appendicular lean mass (ALM) were applied on electrical data measured by BIA in AN patients with BMI <16 kg/m². BIA and DXA were done the same day after overnight fasting. Results were compared with the Bland–Altman method, Pearson correlation and a Lin concordance test. Results: Data from 115 female AN patients (14.6 ± 1.2 kg/m²; 32.3 ± 14.5 years) were included. FM and FFM assessed by DXA were, respectively, 4.2 ± 2.4 kg and 35.5 ± 3.8 kg. The best results were obtained with Sun’s equation: respectively for FM and FFM, Bland Altman bias at 0.548 and 0.706 kg, Pearson correlation r at 0.86 and 0.86 and Lin concordance coefficient at 0.81 and 0.84. However, confidence intervals (CI) at 95% were high (−2.73–3.83 kg for FM; −4.55–3.13 kg for FFM). Other equations also showed high 95% CI. Accuracy was acceptable for Sun and Bedogni equations for FFM (approximately 66%) but very low for FM prediction considering all equations (<15%). Concerning ALM evaluated at 14.88 ± 2.04 kg by DXA, only Scafoglieri and Yoshida equations showed acceptable values: bias (−0.2 and 2.8%), Pearson r (0.89 and 0.86), Lin concordance coefficient (0.82 and 0.82) and accuracy (83.5 and 82.6%). Confidence intervals at 95% were high for both equations (−2.1–2.0 for Scafoglieri equation and −1.6–2.4 for Yoshida equation). Conclusion: In AN patients with BMI < 16 kg/m², no BIA equation tested was adapted to evaluate BC at the individual level.

Students belong to a group of high health risks, since during this period of development, young people are under the influence of the inevitable processes of active physiological restructuring of the body and intensive socialization of the individual. The purpose of the study is the anthropometric indicators and indices of physical development of 1648 girls aged 17-21 of the Republic Mordovia. Anthropometric measurements included the determination of the following parameters: body weight, standing and sitting body length, circumference of the chest, shoulder, forearm, wrist, thigh, abdomen, buttocks, lower leg, ankles. The comprehensive research program was designed in such a way that it was possible to calculate body surface areas, weight and height values, body strength indices and body proportionality indices. It was found that in the studied population, girls have a wide face, a narrow long nose, and a medium-sized skull. The majority of the population is characterized by the absence of excess body weight. Girls have a normosthenic type of constitution, have an average level of physical development, an average level of body density. Among female students, a mesomorphic type of physique is common with proportional body development, a normal proportion of the bone component and a slightly increased proportion of fat and muscle components. The inversion and dysplasia of sexual dimorphism revealed in the course of the study may be a response of a more labile female body to the negative influences of social and environmental factors.

Purpose:To investigate the relationship between race performance and lean mass (LM) variables, as well as to examine sex differences in body composition in elite-standard cross-country skiers.Methods:Thirty-four elite cross-country skiers (18 men and 16 women) underwent a dual-emission X-ray-absorptiometry body-composition test to determine LM, fat mass, and bone mineral content. For both sexes, performance data were collected from a sprint prologue and a distance race.Results:The absolute expression of LM variables (whole-body [LMWB], upper body [LMUB], and lower body [LMLB]) was significantly correlated with finishing time in the sprint prologue independent of sex. Distance-race performance was significantly related to LMWB, LMUB, and LMLB in women; however, no correlation was found in men. Men had a significantly higher LM and lower fat mass, independent of expression (absolute or relative), for the whole body, arms, trunk, and legs, except for the absolute fat mass in the trunk.Conclusions:The absolute expressions of LMWB, LMUB, and LMLB were significant predictors of sprint-prologue performance in both sexes, as well as of distance-race performance in women only. Compared with women, male skiers have a higher LM in the body segments that are major contributors to propelling forces. These results suggest that muscle mass in the lower and upper body is equally important for race performance; thus, more focus of elite skiers’ training should be directed to increasing whole-body muscle mass to improve their competitive performance capability.
