I know this isn't an orthopedic issue, but it sounds like the severe form of this condition can have major impacts on athletes. A prominent female high school distance runner had to withdraw from the cross country national championships because of it. This is common knowledge, as the article on her withdrawal is here: www.digitalsports.com/NJ/ScottClayton/TauroFootLocker.htm The little that I have read about this condition mentions urine with a "cola-like" color as a symptom. I realize that this is likely due to the accumulation of myoglobin from the breakdown of muscle tissue. However, I do know that all athletes will have myoglobin in their urine after a particularly strenuous effort. But, in normal circumstances, the urine is not the color of a cola drink. What are some risk factors for the development of the severe form of this condition? I had never even heard of this condition prior to reading this article about this runner withdrawing from the championships. What is the mechanism behind the development of this condition? I am not a physician, so I know very little about this. This subject interests me, because I am a distance runner myself.

Rhabdomyolysis is the breakdown of myocytes (muscle cells) with the release of the inner cellular contents into the body's circulation. Exertional rhabdomyolysis is precipitated by strenuous activity or exercise. Causes/Risk factors include trauma/muscle injury, malignant hyperthermia, dehydration, stimulants, antihistamines, alcohol, infection/fever, eccentric muscle loading, deconditioned athletes, convulsions/seizures, burns etc. From the story you posted, it sounds as if she was a little dehydrated, ill with "the flu," and was pushing herself to exertion, all of which put her at an increased risk for rhabdomyolysis.
