Send us Fan Mail Can exercise actually slow Parkinson's disease progression? In this episode, we break down the game-changing clinical findings from…
So for a long time, researchers knew that exercise made people feel better.
I know I feel better when I exercise, and my friends in the Parkinson's classes that I take also seem to feel better when they're done exercising.
But they couldn't definitely prove that there was fundamental changes in the disease timeline because of exercise.
Well, then came the Cycle 2 trial, which is called the Pragmatic Cyclical Lower Extremity Exercise Trial, and that's a mouthful.
Now, this was a massive multi-site randomized controlled trial specifically designed to test whether long-term, high-intensity aerobic exercise could act as a disease-modifying tool.
Now, the study enrolled 256 people with mild to moderate Parkinson's across several major academic medical centers.
Now, the objective was to evaluate whether a structured 12-month aerobic cycling program could slow down the progression of motor disability compared to standard, usual, and customary care, meaning you go to see your neurologist or movement disorder specialist, and they prescribe you some medications and maybe tell you what to do, and then you follow their care plan.
Now, the participants in the active arm of the study were given a home-based stationary cycle and asked to complete a 45-minute session three times per week.
Now, importantly, they utilized virtual coaching and community support to maintain a high cadence, specifically targeting students.
So when they were doing their cycling, they maintained that greater than or equal to 75 RPMs for the 45-minute session, keeping their heart rates in that vigorous zone, which is roughly 60% to 80% of their heart rate reserve.
Now, the findings that were presented by the lead investigator, Dr. Daniel Korkos, and his team were somewhat staggering.
After 12 months, the control group progressed as expected by natural history.
So someone with mild to moderate Parkinson's, after a year, typically there's a progression.
while the high-intensity cycle group demonstrated a significantly lower rate of motor symptom progression.
93% of the people adhered to the program, proving that patients can and will stick to a rigorous program when given the right tools, whether it's a personal coach and then doing something as a community, but they're given ways that they can follow specific instructions to keep their heart rate in a targeted zone.
All right, now that trial forms the backbone of the newly updated Parkinson's Foundation and the American College of Sports Medicine exercise guidelines.
