Introduction. Factors affecting the severity of the course of a new coronavirus infection remain unexplored to the endAim. To study the factors associated with the transition of COVID-19 from moderate to severe form of the disease in patients undergoing inpatient treatmentMaterials and methods. The diagnosis of COVID-19-associated pneumonia was made by a clinician on the basis of PCR test data and an up-to-date chest CT scan. A total of 195 consecutively recruited patients were examined. The average age of the surveyed was 54 (12.1) years.Results. Significantly more patients with severe coronavirus infection at the time of hospitalization were active tobacco smokers (33 (29.73%) vs 67 (79.6%); p < 0.002) and had a BMI consistent with pre-obesity/obesity (42 (37.84%) vs 44 (52.38%); p = 0.027). In patients with severe COVID-19, a significantly higher content of leukocytes was noted in the complete blood count (6.054 (2.813) vs 7.307 (4.707); p = 0.021). The groups also differed significantly in the content of micro- and macroelements. The imbalance of minerals revealed in our study is published for the first time, because. The study of the content of Al, B, Li, Co, Sr and Si in patients with COVID-19 was not carried out.Conclusion. The revealed changes in the microelement status require further study to confirm their significance in the development of a severe form of a new coronavirus infection in patients.

Objective: to determine the content of hormones, as well as some macro- and microelements in athletes-wrestlers outside the period of competition and active training.Materials and methods: the study involved 66 athletes-wrestlers and 107 students involved in sports professionally. The level of hormones and vitamin D was determined by the ELISA method. To analyze the content of macro- and microelements, the subjects were cut off a lock of hair from the back of the head in an amount of at least 0.1 g. The studies were carried out on an ICP-MS Agilent 7900 mass spectrometer.Results: levels of cortisol, TSH and T4 are higher, and levels of testosterone, T3 and vitamin D are lower in athletes compared to the control group. An increase in the content of sodium, calcium, potassium, magnesium, cobalt and a decrease in iodine were revealed in fighters from those who were not involved in sports professionally.Conclusion: the data obtained indicate an imbalance in the work of the body’s endocrine systems and impaired adaptation to stress. It is known that the determination of the hormonal status is used to assess the adaptation, the revealed changes in the indicators of vitamin D, macro- and microelements, allow the study of these indicators in order to prevent the syndrome of overtraining of athletes, to maintain and improve sports performance.

Currently, there is a significant increase in the prevalence of obesity among children and adolescents of the world population. Overweight and obesity are a global epidemic of humanity. In economically developed countries, including Russia, on average, every third inhabitant has a weight that exceeds the maximum allowed. Russia ranks 15th in the world in the prevalence of overweight and obesity among children and adolescents. Obesity is now considered as a chronic, relapsing disease associated with the development of a number of diseases that reduce life expectancy and reduce its quality. An important factor in demonstrating the urgency of the problem of child and adolescent obesity is its prognostically adverse effect on obesity in adulthood. The lack of targeted detection of overweight and obesity in children and adolescents in Russia accounts for its late diagnosis specialists. Complications of obesity affect the cardio vascular, reproductive, respiratory, nervous system, digestive organs, musculoskeletal system. In connection with the rise of obesity than the early detection of issues and preventive measures to prevent its further progression. Obesity in the early diagnosis and early treatment is a reversible condition. Important role in the treatment of obesity play a non-drug methods - diet, exercise stress, a variety of physical therapy, taking into account individual tolerance and comorbidity. Physiotherapy treatments have not only symptomatic but also the pathogenic effects, eliminating the primary metabolic and neuroendocrine disorders.

Aim. To evaluate the effectiveness of the developed special sports complex in the prevention of hypodynamia and obesity among firefighters-rescuers.Materials and methods. A survey of 490 men with no history of chronic infectious and non-infectious diseases aged 20-59 was conducted. 328 people were the main group, 162 people were the control group. The baseline data included anthropometric development indicators, bioimpedance test results, the extraction of biochemical blood test results; the body mass index (BMI) and the ratio of waist and hip circumference were determined. A questionnaire was conducted to identify hypodynamia (according to the IPAQ questionnaire) and the nutrition structure (according to the questionnaire on the food label literacy questionnaire, past). Both questionnaires were adapted to the Russian Federation. Statistica for Windows 8.0 was used for statistical processing. We used a comparison of the means of the Student method. To compare the values expressed in percent, the method of inverse trigonometric Fisher transformations was used.Results. We have developed and proposed for firefighters-rescuers, included in the main group, special sports complexes, which were used for 6 months. These complexes represent additional physical training by the developed method. There are two of them: one with an emphasis on the prevention and rehabilitation of people with osteochondrosis of the lumbar spine, and the other for cervical and thoracic localization, including with a syndrome of shoulder-scapular periarthritis.Classes were held 3 times a week, the duration of 1 session was 45-50 minutes. The choice of the complex was carried out at the request of firefighters-rescuers. The first complex was selected by 52 people. Based on the results of the study, against the background of the use of sports complexes, there was a 2-fold decrease in the incidence of obesity. Such a high efficiency is due to the fact that obesity of the I degree prevailed among the firefighters-rescuers. In addition, the frequency of occurrence of dyslipidemia, hyperglycemia, and hypodynamia decreased.Conclusion. The use of this sports complex can reduce the risk factors for development of disability among rescue firefighters by preventing hypodynamia and reducing the incidence of hyperglycemia and dyslipidemia, as factors in the development of obesity.
