Is the gut microbiota bacterial abundance and composition associated with intestinal epithelial injury, systemic inflammatory profile, and gastrointestinal symptoms in response to exertional-heat stress?

Objectives The study aimed to examine if the α-diversity and relative abundance of the gastrointestinal bacterial taxa is associated with the response magnitude of markers characteristic of exercise-induced gastrointestinal syndrome in response to exertional-heat stress. Design Cross-sectional. Methods Twenty-two endurance-trained athletes completed 2 h running at 60% V . O2max in hot ambient conditions (35.2 °C, 25% relative humidity). Faecal...
