Exercise of various intensities, including marathons, triathlons, and cycling competitions, affects the gastrointestinal tract (GIT) by eliciting gut dysmotility symptoms. In relation to
gastrointestinal symptoms, many studies have presented evidence of the effects of different
intensities of pre-and post-meal exercise. However, the mechanisms are still unknown. A
hypothesis is that the redistribution of blood flow causes gastrointestinal ischemia, mechanical forces, changes in gastrointestinal mucosal activity, neuroendocrine changes, and stress.
It is estimated that 30–90% of distance runners experience intestinal problems related to exercise. These symptoms can include vomiting, nausea, heartburn, gastroesophageal reflux, diarrhea, stool bleeding, and more frequent bowel movements. The effects of gastric
emptying are less clear. However, high-intensity exercise induces a decrease in gastric emptying, while low-intensity exercise such as walking (at 28, 41, and 56% of VO2 max) and running (at 57 and 65% VO2 max) accelerate it.
This Research Topic aims to draw together a collection of papers that evaluate the different effects of physical exercise on gastrointestinal pathophysiology in health and illness. We welcome the submission of manuscripts including, but not limited to, the following topics: Special focus will be given (but is not restricted) to:
• Exercise Physiology and Gastrointestinal Motility
• Exercise Physiology and Intestinal Permeability
• Microbiota and Exercise
• Exercise, Nutrition, and Gastrointestinal Tract
• Exercise and Gastrointestinal Disorders
• Exercise, Supplemental Nutrition, and Gastrointestinal Disorders.
