Who could benefit from this research

Could help

Adults diagnosed with Parkinson’s disease who can safely participate in moderate to high‑intensity aerobic exercise.

Less likely to help

Some individuals with advanced PD or certain medical conditions may not be eligible or may not benefit from this exercise protocol.

What this research studies

If you have Parkinson’s, this study checks whether exercising at a harder, heart‑pumping pace, four times a week for 30 minutes, can slow how the disease progresses beyond what standard treadmill work already does. Participants are assigned to either a moderate or high‑intensity treadmill program over up to two years, with careful monitoring of safety and changes in movement, skills, and measurable markers of the brain. The goal is to see if higher‑intensity exercise offers extra benefits for slowing PD compared with existing exercise approaches. If successful, this could lead to a non‑drug option to help preserve function in PD.

Why it matters

Potential benefit: If effective, high‑intensity exercise could become a recommended, non‑drug option to slow PD progression and improve daily function.

How similar studies have gone: A prior Phase 2 trial showed promising signals and has been widely cited; this Phase 3 study tests durable, real‑world benefits.
