По результатам максимальной работоспособности спортсменов — относительной скорости (Vотн.), показанной в нагрузочном тесте, — группу разделяли на две подгруппы: спортсменов с высокой и низкой работоспособностью (СВР и СНР соответственно). Для определения наличия или отсутствия дисбактериоза кишечника применяли микробиологическое исследование кала.</p></sec><sec><title>Результаты</title><p>Результаты: у спортсменов из группы СВР достоверно выше были значение коэффициента экономичности кровообращения (КЭК) и уровень аспартатаминотрансферазы. В группе СВР была выявлена положительная корреляционная взаимосвязь между уровнем активности ферментов печени и микрофлорой кишечника, а также активностью фермента аланинаминотрансферазы и скоростными характеристиками. Среди спортсменов из группы СНР выявлены положительные корреляционные связи показателей работоспособности с гемолитической кишечной палочкой, а у 40 % из них было отмечено наличие условно патогенных бактерий.</p></sec><sec><title>Выводы</title><p>Выводы: у спортсменов с высоким уровнем физической работоспособности функциональное состояние характеризовалось активацией анаболических процессов, тогда как у спортсменов с низким уровнем физической работоспособности преобладали катаболические процессы, обусловленные присутствием в кишечнике условно патогенных и патогенных микроорганизмов. Таким образом, можно сделать вывод о том, что состояние микробиома кишечника может влиять на различные аспекты работоспособности спортсменов из циклических видов спорта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: to assess the functional-metabolic state and intestinal microbiota of athletes of cyclic sports with high and low levels of performance.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: the study involved 20 male athletes of cyclic sports aged 18–22 years. Based on the results of the athletes’ maximum performance — relative speed (Vrel.), shown in the ergometry test, the group was divided into two subgroups. To determine the presence or absence of intestinal dysbacteriosis, microbiological examination of feces was used.</p></sec><sec><title>Results</title><p>Results: High performance athletes (HPA) had significantly higher values of the circulatory efficiency coefficient (CEC) and aspartate aminotransferase (AST). In the HPA group, a positive correlation was found between the level of liver enzyme activity and intestinal microflora, as well as the activity of the ALT enzyme and speed characteristics. In the group of low performance athletes (LPA), positive correlations were found between performance indicators and hemolytic E. coli. Opportunistic bacteria were found in 40 % of men in the LPA group.</p></sec><sec><title>Conclusion</title><p>Conclusion: In athletes with a high level of physical performance, the functional state was characterized by the activation of anabolic processes. Whereas in athletes with a low level of physical performance, catabolic processes prevailed, caused by the presence of opportunistic and pathogenic microorganisms in the intestine. It was concluded that athletes should regularly undergo ergometric testing with a study of the intestinal microbiome in order to prevent the development of dysbiosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>спортсмены</kwd><kwd>нагрузочный тест</kwd><kwd>скорость</kwd><kwd>работоспособность</kwd><kwd>микробиота кишечника</kwd><kwd>микробиом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>athletes</kwd><kwd>stress test</kwd><kwd>speed</kwd><kwd>performance</kwd><kwd>gut microbiota</kwd><kwd>metabolism</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Clark A., Mach N.
