Recruiting studies
- NCT05965518Recruiting
High-intensity exercise for brain and blood-vessel health in HIV
This trial tests whether high-intensity exercise can improve blood-vessel health and brain function in adults with HIV who are not very active and have thinking/memory problems. If you qualify, you’ll be asked to safely complete exercise and other study assessments.
Birmingham, AlabamaAges 50 years+ - NCT05918263Recruiting
Exercise to slow prostate cancer in men on active surveillance
This trial tests whether moderate exercise can help keep low-risk prostate cancer from growing in men who are monitoring their cancer instead of treating it right away. It may be especially helpful for men with certain risk factors like obesity or being Black or African American.
Boston, MassachusettsAges 18 years+ - NCT05877196Recruiting
Adaptive walking and fitness program for mild memory decline
This study tests an “adaptive” exercise plan that adjusts over time to help improve aerobic fitness and your body’s fitness response in people with mild memory problems or early Alzheimer’s. It may help you safely build the kind of fitness that supports brain health, while researchers monitor changes with fitness testing and blood work.
Phoenix, ArizonaAges 65 years+ - NCT05625204Recruiting
HIIT exercise program to improve frailty in older veterans
This trial tests a high-intensity interval training (HIIT) exercise program to help older veterans feel stronger and more resilient and to reduce frailty. It may help people who are not yet very frail (or are just starting to become frail) but can safely exercise.
Kansas City, MissouriAges 65 years+ - NCT05218083Recruiting
Mobile rehab program with interval exercise after COVID-19
This trial tests a coach-supported, phone-based rehabilitation program that includes high-intensity interval-style exercise for people recovering from COVID-19 after a hospital stay. It may help improve breathing, strength, and walking by providing structured exercise at home.
Birmingham, AlabamaAges 18 years+ - NCT05123963Recruiting
Timed lifestyle plan to improve blood sugar in prediabetes
This trial tests whether matching daily lifestyle habits to a 24-hour body rhythm can improve blood sugar levels in people with prediabetes. You may be asked to follow a detailed schedule and avoid certain medicines for a short time before study visits.
Sherbrooke, QuebecAges 45–75 - NCT04477330Recruiting
Brain stimulation to improve walking after a stroke
This study tests whether a brain stimulation method (“cortical priming”) can improve walking after a stroke. It may help people with ongoing walking problems improve gait and leg control over a rehabilitation program.
Chicago, IllinoisAges 18 years+ - NCT03397602Recruiting
Exercise program for long-term atrial fibrillation
This trial studies how an exercise training program affects people with persistent or permanent atrial fibrillation (an irregular heart rhythm). It may help improve how you feel and how well your heart and body handle activity.
London, OntarioAges 40 years+ - NCT07229196Recruiting
Comparing two exercise programs for lowering blood pressure
This study compares two types of exercise programs (short bursts of high-intensity exercise vs. moderate continuous exercise) to see which one lowers blood pressure better in people with hypertension. You may qualify if you have high blood pressure and are between 30 and 59 years old.
La Plata, Buenos AiresAges 30–59

Common questions
- Are there clinical trials for high intensity interval training?
- Yes. Clin2 currently lists 81 recruiting high intensity interval training 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 high intensity interval training 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 high intensity interval training 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.
