Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Body temperature fluctuations induced by acute exercise bouts may influence the intestinal barrier with related effects on epithelial permeability, immune responses, and release of metabolites produced by the gut microbiota.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Untrained males aged 22±1.5 years were randomly assigned to exercise training (ET) with or without post-exercise sauna treatments (S). Participants in the group ET+S (n=8) exercised 60 minutes, 3 times per week, on a bicycle ergometer followed by a 30-minute dry Finish sauna treatment. The control group (ET, n=7) engaged in the same exercise training program without the sauna treatments. Blood and stool samples were collected before and after the 4-week training program. Blood samples were analysed for the concentration of high-sensitivity C-reactive protein (hsCRP) and complete blood counts. Stool samples were analysed for pH, quantitative and qualitative measures of targeted bacteria and fungi, zonulin, and secretory immunoglobulin A. This study evaluated the effects of post-exercise sauna bathing in young men undergoing endurance training on gut bacteria inflammation and intestinal barrier function. Investigators hypothesized that sauna bathing applied immediately after a physical training session may impact homeostatic control of the gut microbiota and the function of the intestinal barrier.
