The folks from Crossfit have a pretty extensive understanding of this condition and have some good info on their site
www.crossfit.com. It's mainly because their workouts tend to cause it in people who are not used to their system or cross training. They even have some of their top athletes who live in a constant partial state of rhabdo (their words from seminar) and are fine. Go to their site, check the forums, the journals and they should have some good stuff about it.
