While conventional wisdom held that people with Parkinson’s disease couldn’t handle high-intensity workouts, it turns out that exercise helps—a lot

People who push themselves to remain physically active after being diagnosed with Parkinson’s disease are on the right track: three vigorous workouts a week can delay the condition’s progress. That was the conclusion of study results US researchers published in the journal JAMA Neurology.
In a randomized study, researchers randomly assigned 128 participants aged 40 to 80 with early-stage Parkinson’s to one of three groups: high-intensity exercise (working to 80 to 85% of maximum heart rate), moderate exercise (60 to 65% of maximum heart rate), or no exercise. None of the participants were taking Parkinson’s medications, so the study results evaluated only the effect of exercise.
After six months, non-exercisers’ scores on a 20-point scale measuring symptom severity had worsened three points and moderate exercisers’ scores had decreased 1.5 points, while scores in the high-intensity group were unchanged.
Parkinson’s disease is a progressive nervous system disorder. Symptoms include tremors, often beginning in the hand, impaired movement, muscle stiffness, and balance problems.
