This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a shorter exercise program can work just as well as a longer one for people living with schizophrenia spectrum disorders or bipolar disorder. People with these conditions often struggle with symptoms that don't fully respond to medication, and they face higher risk of heart disease. Exercise has been shown to help improve both mental symptoms and heart health, but many people find it hard to stick with intense workouts.
People with serious mental illness like schizophrenia and bipolar disorder often stop exercise programs because they're too demanding. This study wants to find out if a shorter, gentler version of high-intensity exercise might help more people stay with the program while still improving their symptoms, mood, thinking, and physical health.

You would come to the hospital twice a week for 26 weeks to do treadmill exercise with a physical therapist supervising. Half of participants will do four 4-minute intense walking or running intervals with rest breaks, while the other half will do one 4-minute intense interval. Before and after the study, you'll have blood tests and answer questions about your symptoms, mood, thinking ability, and quality of life. The sessions are usually done in groups to make them more enjoyable and help people stick with the program.
