Study of Morpho-Functional Characteristics of the Cardiovascular System According to Electrocardiography, Phonocardiography, Echocardiography in Masters Athletics.

Background: Many authors have noted the lack of knowledge on the causal relationship between the degree of physical activity, the dynamics, and outcomes of diseases, as well as the influence of sports history on the rehabilitation potential of former athletes. Purpose: Assessment of the functional state of the cardiovascular system according to the indicators of electrocardiography, polycardiography, echocardiography and the level of physical performance in masters athletes. Patients and Methods: The study included a main group consisting of 100 athletes, who had undergone electrocardiography, poly-electrocardiography, ultrasound echocardiography, heart rate and blood pressure measurement to determine their level of physical performance. The subjects were then divided into 2 groups. The first group included 75 people who continue to be active in regular sports activities. The second group consisted of 25 people who completely stopped training or had only occasional, unsystematic physical activities. A control group of 31 people, consisting of people of the same age who had not been involved in sports earlier, was examined according to the same program. Results: The data obtained by us show that sports activities do contribute to the increasing stability of the body and maximize the deployment of the capabilities of the circulatory system, including their long-term preservation in masters athletic. Athletes who have stopped training have signs of age-related changes in the heart and blood vessels, which seem to be more frequent and earlier than those who continue training. A higher degree of myocardial contractility (in 90.67% of cases) can also be seen in the main group. Conclusion: Masters athletes and those who stopped training after completing their sports career, should have notably thorough medical supervision and undergo regular annual in-depth examination.

Age-Related Study of Anthropometry Indicators, Body Composition, Strength and Vital Capacity at Masters Athletics: How to Postpone Sarcopenia.

Purpose: The purpose of this study was to compare the anthropometric indicators of sports veterans, former athletes who stopped training, and non-sports people aged 40 years and older to assess the impact of regular sports on the stability of the body. Patients and Methods: 100 athletes and 31 people non-sports were included in the study. Athletes were divided into two groups depending on the mode of motor activity. The first group (n=75) continued their regular sports activities. The second group (n=25) stopped training. Height, weight, chest circumference, mobility, waist, shoulder circumference, forearm, hip, ankle, fat mass, and muscle mass were measured, and dynamometry was performed. Results: Body weight is statistically significantly (p<0.05) less in those who continue sports (70.7±10.2) classes after 60 years compared with the control group (82.4±9.3). In sports veterans, the chest excursion and the shoulder circumference is statistically significantly (p<0.05) greater than in the control group. In the subjects of the first group aged from 40 to 49 (4551±612) and from 50 to 59 (4242±416), the FVC index was statistically significantly (p<0.05) higher than in the control group (3890±344 and 3786±401, respectively). The body composition of veterans is characterized by a high level of muscle mass and a low level of fat mass. At the age of 40-49, the percentage of muscle tissue in sports veterans was statistically significantly higher (46.32±2.74) (p<0.05) than in the group of athletes who stopped sports activities (44.09±5.29). Conclusion: Veterans of sports demonstrate higher indicators of limb girth and muscle strength compared to untrained people of the same age. In addition, sports veterans have a lower content of adipose tissue and a greater expression of muscle mass. Thus, the data obtained by us show that sports prevent the development of sarcopenia and can also affect cardiovascular risk.

The Contribution of the Intestinal Microbiota to the Celiac Disease Pathogenesis along with the Effectiveness of Probiotic Therapy.

The development of many human disorders, including celiac disease (CD), is thought to be influenced by the microbiota of the gastrointestinal tract and its metabolites, according to current research. This study's goal was to provide a concise summary of the information on the contribution of the intestinal microbiota to the CD pathogenesis, which was actively addressed while examining the reported pathogenesis of celiac disease (CD). We assumed that a change in gluten tolerance is formed under the influence of a number of different factors, including genetic predisposition and environmental factors. In related investigations, researchers have paid increasing attention to the study of disturbances in the composition of the intestinal microbiota and its functional activity in CD. A key finding of our review is that the intestinal microbiota has gluten-degrading properties, which, in turn, may have a protective effect on the development of CD. The intestinal microbiota contributes to maintaining the integrity of the intestinal barrier, preventing the formation of a "leaky" intestine. On the contrary, a change in the composition of the microbiota can act as a significant link in the pathogenesis of gluten intolerance and exacerbate the course of the disease. The possibility of modulating the composition of the microbiota by prescribing probiotic preparations is being considered. The effectiveness of the use of probiotics containing Lactobacillus and Bifidobacterium bacteria in experimental and clinical studies as a preventive and therapeutic agent has been documented.

Metabolic and Body Composition Changes in Ice Hockey Players Using an Ergogenic Drug (Cytoflavin).

BACKGROUND AND OBJECTIVES: In ice hockey, the major physical workload comes from acceleration in all planes of motion and transitions between skating trajectories. Hockey players' anthropometric characteristics correlate with performance. In team sports, the use of ergogenic drugs for recovery is relevant to avoid athletes' overtraining. It is very important to protect athletes' health and allow them to maintain high-performance levels. Cytoflavin is an ergogenic drug whose action is based on the combined effects of its active ingredients (succinic acid, inosine, nicotinamide and riboflavin), which are naturally occurring metabolites that stimulate tissue respiration. The study aimed to assess the 6-week Cytoflavin consumption effects on body composition (body weight, body mass index, body fat percentage and bioimpedance phase angle) and aerobic performance. METHODS: This study included 60 male professional hockey players (aged 19 to 36 years) divided into two groups of 30 subjects: group I (body weight 87.90 ± 7.44 kg, BMI 25.86 ± 2.04 kg/m2) and group II (body weight 87.04 ± 6.22 kg, BMI 25.52 ± 2.38 kg/m2). Athletes in group I received Cytoflavin, whereas athletes in group II did not. RESULTS: In group I, statistically significant reductions in body weight and body mass index were not observed until 14 and 35 days, respectively. In contrast, in group II, both body weight and BMI significantly decreased both times. Aerobic performance significantly increased in both groups, with significantly greater increases in group I. CONCLUSIONS: Cytoflavin can be considered an ergogenic drug that improves body composition parameters, especially in the control of weight reduction and improvement in aerobic performance.

Nitric oxide therapy is beneficial to rehabilitation in professional soccer players: clinical and experimental studies.

Nitric oxide can activate neutrophils and macrophages, facilitate the synthesis of collagen, which allows significantly accelerating the regeneration of traumatized tissues. We studied the effects of nitric oxide-containing gas flow generated by plasma-chemical device "Plason" in a rat model of full-thickness wounds. Histological and morphometric analyses revealed that Plason treated wounds expressed significantly fewer signs of inflammation and contained a more mature granulation tissue on day 4 after the operation. Considering the results of the experimental study, we applied the Plason device in sports medicine for the treatment of lower limb bruises of 34 professional soccer players. Athletes were asked to assess the intensity of pain with the Visual Analogue Scale. Girths of their lower limbs were measured over the course of rehabilitation. Nitric oxide therapy of full-thickness wounds inhibited inflammation and accelerated the regeneration of skin and muscle tissues. Compared with the control, we observed a significant reduction in pain syndrome on days 2-7 after injuries, edema, and hematoma, and shortened treatment duration. This pilot study indicates that the use of nitric oxide is a promising treatment method for sports injuries.

Risk Factors for Locomotive Crew Members Depending on Their Place of Work.

PURPOSE: The purpose of this study is to examine the prevalence of workplace exposure, behavior, and individual health conditions, along with resulting medical activity among locomotive crew members depending on their place of work. PATIENTS AND METHODS: Participants included 5585 train drivers and 3723 train drivers' assistants (7% of the total train operators in the Russian Federation). Measured height and weight were used to calculate body mass index (BMI), and waist circumference, pulse rate, and blood pressure were also measured. The risk assessment was conducted using the STEPS tool. The level of commitment to a Healthy Lifestyle was assessed based on World Health Organization recommendations. Occupational risk factors were surveyed. Morbidity was analyzed over the past year. RESULTS: The lowest frequency of work exposure risk factors was found for employees of the Trans-Baikal railway; the highest was among Krasnoyarsk, North, and South-East. The participants from the Far East and October Railways had the lowest self-reported frequency of behavioral risk factors. The participants from the Eastern Siberian, October, and Southern Urals railways had the lowest occurrence of individual health conditions. The participants from the East Siberian, Far East, Kuibyshev, and Sverdlovsk railways were the least likely to visit their doctor, take temporary disability leave, or be hospitalized. The total assessed Healthy Lifestyle commitment index was higher for participants from the Far Eastern and Southern Urals railways. The participants from the Moscow and October railways were the least committed to a Healthy Lifestyle. CONCLUSIONS: Significant differences exist between risk factors and Healthy Lifestyle commitment between railways. Future research should examine changes due to a new corporate health program introduced in 2020.

A Metabolic Activity Recovery of the Intestinal Microbiota in the Patients with Bronchial Asthma.

Background: It was established that the high biological diversity of intestinal microorganisms promotes the needed SCFAs production, which induces immune regulatory pathways and contributes to the anti-inflammatory response. Study. A group of 30 patients with allergic bronchial asthma (BA) were investigated in our study. All of the patients were tested for the presence of SIBO by the SCFA spectrum determination. For the SIBO treatment, 10 patients from the studied group were prescribed Rifaximinum with the 200 mg dose at 3 times a day for a week; the other 10 patients were prescribed Rifaximinum at the same dose, followed by the administration of the Lactobalance probiotic in capsules at 3 times a day for a month. A month probiotic course was assigned to the remaining 10 patients without SIBO, as part of the BA complex therapy. The SCFA studies were immediately carried out for all of the patients after the 1 month probiotic therapy course. Results: A normalization of the SCFA spectrum and anaerobic index for all of the studied patients were noted. Upon taking the probiotics, it was revealed in the patients without SIBO that the total content of fatty acids (p < 0.001), acetic and butyric acid (p < 0.001) had increased. The Rifaximinum course, followed by administration of the probiotics led to a decrease of the relative amount of isoacids and ratio of isoacids/acids in the studied patients as compared to the patients who had received Rifaximinum for the SIBO treatment only (p < 0.05). Conclusion: The obtained results demonstrate a potential opportunity of the drug influence on the active bacterial metabolites composition and amount in the intestinal biotope; as it was confirmed by the restoration of the intestinal microbiocenosis and microorganism habitat.

Changes in kinesiostabilogram parameters and movement speed of stroke patients while increasing their physical activity due to the use of biofeedback method.

Balance disorders are complications of stroke survivors. Aim of this study was the establish effectiveness of the biofeedback approach. In this intervention study 245 patients with early diagnosis of acute disturbance of cerebral circulation (ADCC) were examined. Patients able to move independently were treated by standard conservative ADCC therapy on an outpatient approach, but they continued to have problems with coordination of movement in upright position. Then they were submitted to an increasing physical activity based on five sessions of biofeedback, i.e., a complex rehabilitation of patients with motor pathology "Trust-M" according to TU 9442-001-63704475-2010. Mobility rates were assessed using a web camera. Patients' quality of life was evaluated by SF-36 questionnaire and the Hospital Anxiety and Depression Scale (HADS). All parameters were recorded before and after 5 sessions of biofeedback. After treatment, the stability indicators improved and all patients showed a significant increase in motion rate and quality of life. At the same time, the severity of pain and of depression and anxiety decreased. Negative correlations of average strength between the quadrant and patient HADS scaling rates were obtained. In conclusion, our work shows effectiveness of the biofeedback technique for correcting coordination in stroke survivors.
