What this trial studies

This exploratory study aims to assess the impact of cardiovascular endurance training (CET) on the severity of symptoms in patients with irritable bowel syndrome (IBS) who lead a sedentary lifestyle. The study will evaluate changes in IBS symptom severity and explore underlying mechanisms such as dietary adaptations, mental well-being, and alterations in the gut microbiome. By focusing on a small group of patients, the study seeks to gather preliminary data on how regular physical activity may influence IBS symptoms and related factors. The findings could provide insights into lifestyle modifications as a management option for IBS.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 who meet the ROME IV criteria for IBS and have a sedentary lifestyle.

Not a fit: Patients with cardiorespiratory disorders, active psychiatric conditions, or other significant gastrointestinal disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new non-pharmacological approach to alleviate symptoms of IBS through physical activity.

How similar studies have performed: While research on physical activity's role in IBS is limited, similar studies exploring lifestyle modifications have shown promising results.
