Purpose of Review: This study reviewed the concept and assessment tools of physical activity (PA), the level and limiting factors of PA in people with inflammatory bowel disease (IBD), and its impact on patient clinical outcomes, aimed at providing a reference for exercise‐assisted treatment of people with IBD.Recent Findings: The current findings of PA in patients with IBD focus on the risk of disease, promoting and limiting factors, and the effect of clinical outcomes. Patients with IBD have inadequate levels of PA, and the association of PA with IBD incidence and disease activity remains controversial. Nevertheless, PA has demonstrated beneficial effects on clinical outcomes, particularly in reducing mortality, enhancing quality of life, and improving body composition.Summary: IBD is a chronic disease with no cure. Although medication is the main treatment modality, it requires careful consideration of its risks and benefits. PA has proven to be an effective nondrug treatment that can slow the progression of various chronic diseases and enhance patients’ quality of life. However, the correlation between PA levels and clinical outcomes of IBD remains unclear.
