Intestinal Microbiota Interventions to Enhance Athletic Performance-A Review.

Recent years have witnessed an uptick in research highlighting the gut microbiota's role as a primary determinant of athletes' health, which has piqued interest in the hypothesis that it correlates with athletes' physical performance. Athletes' physical performances could be impacted by the metabolic activity of the assortment of microbes found in their gut. Intestinal microbiota impacts multiple facets of an athlete's physiology, including immune response, gut membrane integrity, macro- and micronutrient absorption, muscle endurance, and the gut-brain axis. Several physiological variables govern the gut microbiota; hence, an intricately tailored and complex framework must be implemented to comprehend the performance-microbiota interaction. Emerging evidence underscores the intricate relationship between the gut microbiome and physical fitness, revealing that athletes who engage in regular physical activity exhibit a richer diversity of gut microbes, particularly within the Firmicutes phylum, e.g.,
