Trial summary

This exploratory study's primary objective is the changes of irritable bowel syndrome (IBS) symptom severity by cardiovascular endurance training (CET) in relation to the baseline sedentary or non-active lifestyle. Secondary endpoints focus on the mechanisms associated with these changes. Read more about this study

About this study

This exploratory study's primary objective is the changes of irritable bowel syndrome (IBS) symptom severity by cardiovascular endurance training (CET) in relation to the baseline sedentary or non-active lifestyle. Secondary endpoints focus on the mechanisms associated with these changes.

These mechanisms relate to dietary adaptations, changes in anxiety, depressive comorbidity, somatisation, alterations in the gut microbiome or metabolome, body composition and measures of cardiovascular fitness. Virtually all IBS guidelines mention lifestyle modifications as a management option.

Research on the role of physical activity remains underassessed as compared to the other interventions. Therefore, an exploratory proof-of-concept study will investigate the influence of regular physical exercise on symptoms in a small group of IBS patients. This study will gather data on putative underlying mechanisms related to dietary factors, faecal microbiome and metabolome, mental well-being, body composition and cardiovascular fitness.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiovascular endurance trainingOther

    Based on the results of a maximal effort test, investigators will provide a personalised training program. Results of a submaximal effort test after 6 weeks, will allow for adaptation of the training program for the remaining training period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of IBS Symptom severity

    this will be assessed after patients have done a cardiovascular endurance training

Questions about this trial

What is this clinical trial studying?

A study testing Cardiovascular endurance training in people with Irritable Bowel Syndrome, run by Universitair Ziekenhuis Brussel at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 6 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sébastien Kindt (+32 2 477 ext. 60 11, sebastien.kindt@uzbrussel.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of IBS Symptom severity (time frame: from baseline to 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2026.
