Physical activity in inflammatory bowel disease: benefits, challenges and perspectives.

Abstract

Physical activity is gaining significative interest in the field of inflammatory bowel disease (IBD). In the light of the most recent publications, the present review aims to describe the level of physical activity in adult patients with IBD; describe the current body of evidence on the benefits of physical activity and discuss the challenges and perspectives related to physical activity in this population. Recent studies showed that IBD patients tend to be less active than healthy people. There is growing evidence of a positive impact of physical activity on mortality, quality of life, fatigue, body composition, strength and physical performance. The direct benefits of physical activity on clinical remission and disease activity have recently been observed only in Crohn's disease. Limitations to physical activity related to the disease, such as gastrointestinal and psychological symptoms, need to be considered in this population. Finally, no guidelines are available and there is no evidence regarding the effects of combined physical activity and nutritional support. Although physical activity seems beneficial and safe for IBD patients, future studies are needed to clearly define recommendations in this population.
