In this item from NYTimes Well blog, they discuss research showing that vigorous exercise can diminish the symptoms of Parkinson’s disease in ways that drugs can’t. Yet more evidence that exercise is powerful medicine for many systems in the body, including the nervous system.
One of the interesting aspects of this research is that “force” exercise (when people are compelled to keep up with a pretty rapid cadence on a tandem bike) is much more beneficial than what they call “voluntary” exercise. More evidence that intense workouts are better than mild workouts.
