Evidence suggests that physical activity can help to quell appetite, increase metabolism, improve gastric emptying and lower the relative risk of colon cancer by up to 50%. The key variable to consider in relation to these benefits seems to be the intensity at which the physical activity is performed. Light-to-moderate exercise seems to have a protective effect on the gastrointestinal tract. Additionally, light-to-moderate exercise is well tolerated by and can benefit patients with inflammatory bowel disease and liver disease. By contrast, strenuous bouts of exercise may provoke gastrointestinal symptoms such as heartburn or diarrhoea, while exhaustive exercise has been shown to inhibit gastric emptying, interfere with gastrointestinal absorption and cause gastrointestinal bleeding. Ultimately, it is necessary for the individual to determine which intensity of exercise is most beneficial for achieving their own state of balance. This balance should include optimal gastrointestinal function.
