The main issues related to the assessment of the functional state of the body and the physical performance of the serviceman are considered. The review of modern methods for assessing the functional state and physical working capacity of a person in sports medicine and the physiology of military labor both in Russia and abroad is presented. The choice of the methods allowing to unify approaches to an estimation of military-professional working capacity in stationary and field conditions is proved. It is established that in the scientific research practice of military medical specialists, it is expedient to evaluate the functional state of the serviceman’s organism and its physical working capacity under loads associated with both dynamic and static muscle work. It is determined that ergospirometry is the most acceptable method of assessing the functional state of the body and the physical performance of servicemen in the process of performing dynamic work. It is noted that with the help of ergospirometric testing, it is possible to predict the physical performance of a serviceman and the duration of its preservation at a given level, replacing or supplementing most standard load tests, which is a weighty argument in favor of its choice as a «gold standard». It has been established that to evaluate the functional state of the body and the physical performance of servicemen in the process of performing static work, the main method is stabilometry. A significant number of available stabilometric techniques, including those using biofeedback, significantly expands the possibilities of diagnosing the functional state of the body of a military specialist. It is determined that the most acceptable method for assessing the impact of dynamic loads on the locomotor system of a serviceman is the use of the “motion capture” technology. The main advantages and disadvantages of modern means and methods of studying the functional state and physical working capacity of a person are revealed. The modern hardware and software complexes used to solve scientific research problems of biomedical orientation are listed.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

There are about 466 million people with hearing impairments in the world. The scientific literature does not provide sufficient data on the actual nutrition and other variables of professional deaf athletes. The objectives of this study were to investigate and evaluate the body composition, the physical working capacity, the nutrition intake, and the blood parameters of iron and vitamin D in the Lithuanian high-performance deaf women’s basketball team players. The female athletes (n = 14) of the Lithuanian deaf basketball team aged 26.4 ± 4.5 years were recruited for an observational cross-sectional study. A 7-day food recall survey method was used to investigate their actual diet. The measurements of the body composition were performed using the BIA (bioelectrical impedance analysis) tetra-polar electrodes. In order to assess the cardiorespiratory and aerobic fitness levels of athletes, ergo-spirometry (on a cycle ergometer) was used to measure the peak oxygen uptake (VO2peak) and the physical working capacity at a heart rate of 170 beats per minute (PWC170). The athletes’ blood tests were taken to investigate the red blood cells, hemoglobin, 25-hydroxyvitamin D, ferritin, transferrin, iron concentrations, and total iron-binding capacity (TIBC). The consideration of the VO2peak (55.9 ± 6.1 mL/min/kg of body weight, 95% CI: 51.8, 58.9) and the low VO2peak (56–60 mL/min/kg of body weight) (p = 0.966) in the deaf women’s basketball team players revealed no differences. For the deaf female athletes, the PWC170 was equal to 20.3 ± 2.0 kgm/min/kg of body weight and represented only the average aerobic fitness level. The carbohydrate and protein intakes (5.0 ± 1.3 and 1.3 ± 0.3 g/kg of body weight, respectively) met only the minimum levels recommended for athletes. The fat content of the diet (38.1 ± 4.1% of energy intake) exceeded the maximum recommended content (35% of energy intake) (p = 0.012). The mean blood serum concentrations of 25(OH)D and ferritin (24.1 ± 6.6 nmol/L and 11.0 ± 4.1 µg/L, respectively) predicted vitamin D and iron deficits in athletes. Female athletes had an increased risk of vitamin D and iron deficiencies. Regardless of iron deficiency in the body, the better cardiorespiratory fitness of the deaf female athletes was essentially correlated with the higher skeletal muscle mass (in terms of size) (r = 0.61, p = 0.023), the lower percentage of body fat mass (r = −0.53, p = 0.049), and the reduced intake of fat (r = −0.57, p = 0.040).

The positive is well – proven numerous researches influence swimming on the health of occupying. Therefore question about affecting of employments swimming organism of young swimmers it is necessary to examine taking into account individual of anatomical and physiological features. The aim of the real research was a study of influence of physical activities of step - rising power on breathing and circulation of blood of youths 15-16, regularly visitant a section on swimming. A result of research of indexes of breathing and circulation of blood at the set loading allows describing functional possibilities of youths - swimmers. It was well - proven that the system of preparation of young swimmers was built taking into account age anatomical and physiological features of their organism, and physical activities were adequate to their physiological development. Modern living conditions are characterized by rapid development of automation of production and information technologies, which deprives a person of motor activity. Swimming is one of the most effective means of motor activity that positively influences the functional state of the cardiovascular and respiratory system. Numerous studies have already shown the positive effect of swimming on the health of the practitioners. It should not be forgotten that despite the significant differences in the functional state of the apparatus of external respiration and blood circulation in young swimmers and their peers - not athletes, the organism in both of them has not yet reached maturity and their age development and formation occurs in accordance with a single general biological regularities. Therefore, the question of the impact of swimming lessons on the body of young swimmers should be considered not only in terms of the impact on it of the specific features of the aquatic environment and the requirements of modern training, but also taking into account anatomical and physiological features.

The study included children referred by their state of health to the main medical group (n=91). The average age of boys amounted to 9.6±0.05 years, and of girls - 9.5±0.05 years. The set of methods suitable for the study of school-aged children’s physical working capability at the wide range of accessible tensions was studied. The arrangement of the study met demands of Helsinki declaration. During the study 5 main factors determining physical working capacity structure in 9-10 aged children under the vast range of accessible tensions were found out. All the children were certainly health, went in for physical exercises according to commonly accepted program and did not attend sport sections. In the work there was used the complex of methods suitable for the study of the physical performance of schoolchildren in the large range of available loads. During the study there were selected 5 main factors determining the structure of the physical performance of children aged of 9-1-0 years. It is shown that boys’ and girls’ against background of the preservation of the common structure of the performance contributions of considered factors to the summarized dispersion of the sample, and physiological indices included in to the pattern of specific factors and their weight coefficients are distributed in various ways. Boys aged of 9-10 years were established to exceed girls by physical working capacity in all ranges of available loads. Meanwhile the greatest number of significant differences was identified concerning the variables characterizing working capacity in the moderate and high power relating with mainly aerobic and mixed aerobic-anaerobic power supply of muscular activity. Indices of aerobic capacity are characterized with the most differential “sensibility” in comparison with other energy criteria of the working capacity. The results of the study can be used in the solution of practical tasks according to hygienic rating and control of the value of physical loads of different relative power during the process of physical education of children aged of 9-10 years.
