The percentage of concentric myocardial hypertrophy (pathological remodeling) was 6.5 %, 12.5 % and 7.7 % in the groups 19–25 years old, 26–30 years old and 31 and older, respectively, which must be taken into account when taking measures to prevent overtraining and sudden cardiac death in sports.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133426619","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}

In stressful situations, which include significant physical activity, plasma levels of GLN and GLA decrease as a result of the amino acid being actively consumed in many biochemical reactions. GLN deficiency can lead to a number of negative manifestations in athletes and adversely affect athletic performance. The purpose of this work was to study the effects of glutamine deficiency and the possible replenishment of the deficiency by the consumption of exogenous forms of the substance when using glutamine-containing products; special attention was paid to the study of transient decrease in immune function as a relevant factor that impairs the mode of sports training.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114321226","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 control group consisted of 15 practically healthy untrained student volunteers of the same age. To study the state of free radical oxidation, we used the determination of the content of active products of thiobarbituric acid by reaction with thiobarbituric acid, spectrophotometrically at a wavelength of 535 nm. Determination of diene conjugates was carried out in the heptane phase after preliminary extraction with a heptane-isopropanol mixture at a wavelength of 233 nm.Results: the direction of the shifts in the state of the oxidative balance was established depending on the period of detraining. The concentration of malondialdehyde in former athletes of the 1st group increased by 38.6 %. In the study of the content of diene conjugates, the staging of changes in the studied indicator was established with the maximum values in the former athletes of the 1st group and lower in the 2nd, exceeding the value of this indicator in the control group by 8.0 %.Conclusions: the obtained data can be recommended for monitoring the state of athletes who stopped playing sports and taken into account when prescribing rehabilitation measures for the corresponding contingent.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114931250","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}

This review provides detailed data on the diagnosis, prevalence, classification, etiology. The variety of causes leading to LQTS creates difficulties in the differential diagnosis of this condition and, as a result, LQTS often remains outside the attention of physicians who monitor the health of athletes. Particular attention is paid to the acquired forms of LQTS, particularly, the drug-induced form. The results of studies aimed at studying the prevalence of LQTS and the effect of drugs on the QT interval are presented. The influence of non-steroidal anti-inflammatory drugs on the QT interval is discussed in detail because they are often used by athletes.

Low levels of visibility of clinical manifestations, specific characteristics of individual reactions to injury, anti-aggravation behavior among sportsmen, absence of unbiased methods of diagnostics of SBI are the main reasons behind underestimation of the severity of trauma. Treatment and rehabilitation procedures of mild SBI do not currently consider specific characteristics of trauma, associated with the increase in body and brain temperature and reduced cerebral perfusion during the traumatizing intervention. Injury of the brain causes an increase in cerebral temperature, which, in turn, can aggravate the consequences of traumatization. The control of the temperature of the brain can be achieved with non-invasive method of microwave radiometry, while the technology of craniocerebral hypothermia (CCH), which has evident neuroprotective properties, can aid in the prevention of complications of SBI.","PeriodicalId":309619,"journal":{"name":"Sports medicine: research and practice","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160919","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}
