Exercise program study for blood vessel function in mental health
This study looks at how an exercise program affects blood vessel function (“vascular function”) in people with certain mental health conditions, and compares them to people without those symptoms. It may help researchers understand whether exercise could improve heart and blood vessel health alongside mental health symptoms.
Richmond, VirginiaAges 18–35 - NCT04923958Recruiting

- Yes. Clin2 currently lists 5,570 recruiting health studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a health trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a health trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
