i think the long term goal is to find the biochemical basis for whatever benefit exercise has for neuroprotection and botltle it. i heard there are over 80 clinical studies on exercise listed, 25 in progress, SOME on pd'ers not on meds with delayed start, so we'll know soon enough what the real benefits are on slowing progression.

would i exercise vigorously if a YOPD? You betcha, worse that happens is i get in great shape and gain the general mental and physical benefits of exercise, best is i slow progression. and you'll know soon enough what the real benefits are. no worse than joining a 18month long clinical trial where you take a drug, eh?

i'm not a YOPD'er anymore, i'm doing well when medicated on only sinemet for having been diagnosed in late 2001, i've exercised more than avg. pd'er and will continue to do so, if only for the general benefits.
