In this review, we discuss the following items:（a） Immunosuppression after intense exercise is physiologically significant. （b） Intense exercise-induced immune activation in the gastrointestinal tract may also be physiologically significant. We refer to these apparently conflicting phenomena as the “Super homeostasis theory.” Furthermore, in our view, the ability of the gut microbiota to produce short-chain fatty acids from dietary fiber as a survival strategy may be associated with the “Super homeostasis theory.”
Key Words: Open window theory, Toll-like receptors, Super homeostasis theory, gut microbiota, dietary fiber. |
