Testosterone is the main anabolic hormone, an increase in which during adolescence is associated with faster growth, increased muscle mass, physical strength, and increased overall and aerobic performance. Thus, it is interesting to study the effect of different testosterone levels on metabolic parameters and physical performance of young ice-hockey players.Objective: to compare hematological and biochemical parameters, as well as exercise performance in young ice-hockey players, depending on the testosterone level.Materials and methods: the study included 100 young ice-hockey players aged 15–17 years (average age 15.3 ± 1.1 years). The study group included 25 young ice-hockey players with an increased level of total blood testosterone (> 27.5 nmol/l). The control group included 75 young athletes with normal testosterone levels. All athletes included in the study underwent the PWC 170 test to assess physical performance. Assessment of hematological parameters included hemoglobin (HGB), hematocrit, red blood cell, mean corpuscular volume (MCV), mean concentration hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). β-crosslaps, myoglobin and creatine phosphokinase (CPK) activity were measured to assess the functional state of muscle and bone tissue.Results: A comparative assessment of the CBC in young ice-hockey players did not reveal significant differences depending on the level of serum testosterone level. Tolerance to physical activity in the study groups also did not differ. Young ice-hockey players with increased testosterone levels showed lower β-crosslaps values compared to the control group. The values of other biomarkers of the functional activity of muscle tissue did not depend on the level of testosterone levels.Conclusion: Increased serum testosterone level in the range from 27.5 to 40 nmol/l, detected in young ice-hockey players aged 15–17 years, is not associated with a change in hematological and biochemical parameters. High total testosterone levels do not improve physical performance. It is necessary to continue studies to assess the dynamics of the serum testosterone in young ice-hockey players to clarify the long-term effects of androgens on the metabolic and functional indicators of young athletes. Increasing serum testosterone levels in athletes is subject to wide discussion in the community of sports physicians and endocrinologists.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114243887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The benefits of exercise for the cardiovascular system are apparent. However, the influence of predominantly strength exercises throughout life has not been sufficiently studied. This work details the studies around the structure and function of the heart in sambo veteran athletes residing in the Russian Federation (RF) and the Azerbaijan Republic (AR) as well as the frequency of risk factors for their cardiovascular system.Methods. We examined 55 male athletes aged 45.4 ± 8.3 yrs: 24 sambo veterans from RF (group “RF”), 10 sambo veterans from AR (group “AR”) and 21 persons representing control group (“CG”) (chess, bowling), RF. Questionnaires, analysis of ideal health factors, recording of electrocardiogram in 12 leads, echocardiography, stress test with oxygen analysis were carried out.Results. Maximum exercise power and peak oxygen consumption were higher in the “RF” and “AR” groups compared to the “CG” group. The main abnormalities were hypertrophy of interventricular septum (n = 11, 32.3 %) and left ventricular wall (n = 3, 8.8 %). Concentric left ventricular remodeling was predominant in the “AR” group (5 vs. 1, p < 0.05) and greater left ventricular volume in the “RF” group (65.1 vs. 52.0 ml/m2, p < 0.05). Lower physical performance and the presence of dyslipidemia were significantly associated with parameters reflecting concentric left ventricular remodeling (“AR” group). Various ideal health factors were absent in 10–80 % of the examinees. A total of 7 (20.6 %) veterans were found to have a high risk of cardiovascular diseases according to the questionnaire.Conclusion. Prolonged wrestling exercises allow veterans to maintain high aerobic capacity. Concentric remodeling of myocardium of the left ventricle is combined with higher indices of dyslipidemia in the group “AR” which may be connected to low physical activity and eating habits after sport practice.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129151716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean age of the patients was 53.42 ± 9.16 years, disease duration was 30.32 ± 8.06 days, BMI was 24.75 ± 4.55 kg/m2. Patients underwent history taking, pain level and quality of life were assessed using the visual analogue scale, the SF-36 questionnaire and the AOFAS scale. The functional state of the feet was assessed using plantoscopy, Y-balance test, Friedland index. X-ray parameters were assessed using magnetic resonance imaging.Results: the disease is common among women aged 51 to 60 years. In 100% of cases, there is no traumatic etiological factor, 42.9% of the subjects note an increase in body weight as the cause, 35.2% – the relationship of the onset of pain with wearing flat shoes; men are more likely to associate the onset of symptoms with an increase in physical activity (83.3%). Subjective sensation of pain on the VAS does not depend on gender (p = 0.280), age (p = 0.509), disease duration (p = 0.371), BMI (p = 0.974). X-ray parameters of patients are characterized in 49.5% by the absence of heel exostosis, in other cases, the development of a heel spur is more typical for women (p = 0.019), its length does not depend on the duration of the disease (p = 0.845), age (p = 0.054), BMI (p = 0.196), lifestyle (p = 0.324) and does not correlate with the severity of pain (p = 0.691). The level of pain is directly proportional to the thickness of the plantar fascia (p < 0.001, ρ = 0.459). Calcaneal edema is observed in 14.3 % of patients, soft tissue edema — in 18.7 %; there was no relationship between calcaneal edema (p = 0.604) and soft tissue edema (p = 0.541) with the severity of pain, and calcaneal edema directly correlates with BMI (p = 0.029).Conclusion: These studies suggest that among the predictors of the development of plantar fasciitis, the most significant are female gender, overweight, wearing flat shoes, and the disease itself is not always a consequence of the development of a heel spur.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134243703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vaccination attitudes in young adults were studied both in the general population and among those who are professionally involved in sports, since attitudes towards health and the initial level of physical resources are important for forming attitudes towards vaccination. A total of 2579 people aged 18 to 40 were examined. Of these, 2233 are from the general population, 346 are high performance athletes.Methods. This was a cohort cross-sectional study. A specially designed questionnaire was used, located on Internet resources 2 months after the start of mass vaccination in Russia.Results. In the group of elite athletes, there are significantly more people who consider vaccination unnecessary or treat it indifferently, and a smaller proportion of those who consider it useful or doubt its effectiveness as compared to the general population of the same age. Low adherence to vaccination may be associated with fear of potential complications. Among elite athletes, there are significantly more people who are seriously afraid of complications from vaccination — 143 (41.3 %), compared to the first group of respondents — 745 (33.4 %) (p < 0.01, φ = 2.839). Probably, these concerns are related to the crucial importance of health and physical condition for professional athletes.Conclusions.
