The gut microbiota has been proposed as a modulating factor for recovery through anti-inflammatory mechanisms, oxidative stress management, sleep regulation, and biosynthetic potential for essential micronutrients. This review examines the mechanisms linking gut microbiota composition and function to athletic recovery and critically evaluates the evidence supporting its application in sports medicine. Athletes appear to harbor a more enriched microbial biosynthetic potential, with substantially greater numbers of high-biological-impact synthases involved in the production of vitamins, amino acids, and bioactive metabolites. Short-chain fatty acids, particularly butyrate and propionate, have demonstrated anti-inflammatory effects in preclinical studies, with emerging evidence in humans. The gut\u2013brain axis has been proposed to modulate recovery by regulating neurotransmitter production and controlling circadian rhythms. Sport-associated microbial signatures seem to reflect metabolic demands, with endurance athletes showing enrichment for Prevotella and Veillonella, while strength athletes tend to harbor higher levels of proteolytic bacteria. Probiotic interventions with multi-strain Lactobacillus and Bifidobacterium formulations have reported reductions in inflammatory markers, improvements in oxidative stress biomarkers, and enhanced sleep quality in small-scale randomized controlled trials involving athletic populations, and improvements in self-reported sleep quality in a controlled, non-randomized study in elite athletes. Optimizing gut microbiota composition and function offers a promising complementary strategy for enhancing recovery in elite athletes. Potential applications that require prospective validation include sport-specific probiotic interventions, nutritional strategies to enhance short-chain fatty acid production, and the integration of microbiota assessment with traditional recovery monitoring. Further research is needed to establish standardized protocols and identify predictive biomarkers of individual response to microbiota-targeted interventions.<\/jats:p>","DOI":"10.3390\/nu18142403","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T01:01:28Z","timestamp":1784768488000},"page":"2403","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["From Mechanisms to Practice: Gut Microbiome-Based Strategies for Supporting Recovery in Elite Athletes"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4042-6109","authenticated-orcid":false,"given":"Junior","family":"Carlone","sequence":"first","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement, University of Verona, 37134 Verona, Italy"},{"name":"Department of Movement, Human and Health Sciences, University of Rome \u201cForo Italico\u201d, 00135 Rome, Italy"},{"name":"Division of Pediatric Gastroenterology and Nutrition, Mass General for Children and Harvard Medical School, Boston, MA 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4929-2764","authenticated-orcid":false,"given":"Paolo","family":"Sgr\u00f2","sequence":"additional","affiliation":[{"name":"Department of Movement, Human and Health Sciences, University of Rome \u201cForo Italico\u201d, 00135 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2648-8406","authenticated-orcid":false,"given":"Attilio","family":"Parisi","sequence":"additional","affiliation":[{"name":"Department of Movement, Human and Health Sciences, University of Rome \u201cForo Italico\u201d, 00135 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2134-0261","authenticated-orcid":false,"given":"Alessio","family":"Fasano","sequence":"additional","affiliation":[{"name":"Division of Pediatric Gastroenterology and Nutrition, Mass General for Children and Harvard Medical School, Boston, MA 02114, USA"},{"name":"Department of Nutrition, Harvard T.H.
