Parkinson's Disease - How Much Exercise Improves Symptoms?


​For over two decades, Daniel Corcos has researched Parkinson's disease. During his studies he spent the majority of the past decade focusing on the effects of exercise. At present, Corcos is co-leading a study funded by a four-year, $3 million grant from the National Institute of Neurological Disorders. The aim of the study is to assess the benefits of aerobic exercise in controlling symptoms in individuals recently diagnosed with Parkinson's disease.

In the new study, Corcos, and co-researcher Margaret Schenkman of the University of Colorado-Denver, will assign individuals recently diagnosed with Parkinson's disease to 1 of 3 groups:

  • Participants in the first group will continue at their current activity level
  • Those in the second group will engage in 30 minutes of endurance exercise on a treadmill 4x per week - at between 60-65% of maximum heart rate
  • Participants in the third group will engage in a more vigorous workout at between 80-85% of their maximum heart rate.
