“…The microbiota intervenes in the complex regulation of gastrointestinal function, in enteric immunity, in the regulation of some endocrine aspects, and in the management of oxidative stress [6,65,73,74]. To analyze these aspects, it is necessary to consider how, at the colon level, various polysaccharides and substances of vegetal origin are used as energy substrates and fermented by various microorganisms, including lactobacilli, Bifidobacterium, Clostridium, and Bacteroides, producing SCFA and gas that can be used by bacteria such as reductive acetogens, sulfate-reducers, and methanogens [6,75,76].…”

Intense physical exercise can be related to a significant incidence of gastrointestinal symptoms, with a prevalence documented in the literature above 80%, especially for more intense forms such as running. This is in an initial phase due to the distancing of the flow of blood from the digestive system to the skeletal muscle and thermoregulatory systems, and secondarily to sympathetic nervous activation and hormonal response with alteration of intestinal motility, transit, and nutrient absorption capacity. The sum of these effects results in a localized inflammatory process with disruption of the intestinal microbiota and, in the long term, systemic inflammation. The most frequent early symptoms include abdominal cramps, flatulence, the urge to defecate, rectal bleeding, diarrhea, nausea, vomiting, regurgitation, chest pain, heartburn, and belching. Promoting the stability of the microbiota can contribute to the maintenance of correct intestinal permeability and functionality, with better control of these symptoms. The literature documents various acute and chronic alterations of the microbiota following the practice of different types of activities. Several nutraceuticals can have functional effects on the control of inflammatory dynamics and the stability of the microbiota, exerting both nutraceutical and prebiotic effects. In particular, curcumin, green tea catechins, boswellia, berberine, and cranberry PACs can show functional characteristics in the management of these situations. This narrative review will describe its application potential.

“…В толстой и слепой кишке сложные полисахариды растительного происхождения перевариваются и затем ферментируются микроорганизмами Lactobacillus, Bifidobacterium, Clostridium, Bacteroides в КЖК и газы, которые используются в качестве источников углерода и энергии специализированными бактериями (восстановительные ацетогены, сульфатредуцирующие бактерии и метаногены) [20,24,27,34]. Состав микробиоты, метаболические взаимодействия между видами микроорганизмов, а также количество и тип основных пищевых макро-и микроэлементов определяют типы и количество КЖК, продуцируемых кишечными микроорганизмами [25,58]. Чем больше полисахаридов растительного происхождения, олигосахаридов, устойчивого крахмала и клетчатки получает человек, тем интенсивнее его бактерии ферментируют неперевариваемые компоненты пищи в полезный КЖК.…”

Fatigue, mood disturbances, lack of performance, and gastrointestinal disturbances are common among athletes during training and competition. Psychosocial and physical demands during intense exercise can initiate a stress response that activates the sympathoadrenal and hypothalamic-pituitary-adrenal axes, resulting in the release of stress and catabolic hormones, inflammatory cytokines, and microbial molecules. The gut is home to trillions of microorganisms that play fundamental roles in many aspects of human biology, including metabolism, neuroendocrine, and immune function. The microbiome and its influence on host behavior, the gut barrier, and immunity is a critical aspect of the gut-brain axis. Data have been obtained showing a high correlation between physical and emotional stress during exercise and changes in the composition of the gastrointestinal microbiota. Modifications to the composition of the microbiota in professional athletes can improve training efficiency, improve athletic performance and shorten the recovery period after intense physical exertion.

Background: Little data are available on the subject of gut microbiota composition in endurance athletes as well as connections between diet and specific bacteria abundance. However, most studies suggest that athletes' microbiota undergoes major alterations, which may contribute to increased physical performance. Therefore, we decided to investigate differences in gut microbiota between healthy controls and endurance athletes. Materials and methods: Stools samples were collected from 14 marathon runners, 11 crosscountry skiers and 46 sedentary healthy controls. The athletes' diet evaluation was performed with 24-h diet recall, using the Aliant programme. The 16S gene sequencing was performed using the Ion 16S Metagenomics Kit on Ion Torrent PGM sequencer. Taxonomic classification and diversity indices computation was performed with Mothur. Results: 20 and 5 taxa differentiated healthy controls from marathon runners and crosscountry skiers, respectively. Both groups presented a lowered abundance of major gut microbiota genus, Bacteroidetes and higher abundance of Prevotella. The athletes' microbiome was also more diverse in crosscountry skiers than the one of sedentary controls (Simpson index p-value at 0.025). Thirtyone strong correlations (Spearman's coefficient > 0.6) were uncovered between bacteria abundance and diet, including inverse correlation of Prevotella with sucrose intake, Phascolarctobacterium with polyunsaturated fatty acids as well as positive correlation of Christensenellaceae with folic acid intake and Agathobacter with fiber amount in diet. Conclusions: The excessive training associates with both differences in composition and promotion of higher bacterial diversity. Taxons enriched in athletes are known to participate in fiber fermentation.
