How many of you have heard of rhabdo, or more accurately, rhabdomyolysis? That was the question I asked during the 9 and 10am WODs yesterday. I would guess that less than half the crew raised their hands. We've done a disservice to you by not educating you guys and we appologize for that. You may have heard that one of our friends was diagnosed with rhabdo. She, like many of you, had never heard about it. We're going to change that starting with tonight's post.

Cases of rhabdo have been reported in CF athletes, marathon runners, rugby athletes, soccer players, and in one well-publicized case last year, 12 members of the University of Iowa football team.

Here's a snapshot from the US National Library of Medicine:

Rhabdomyolysis is the breakdown of muscle fibers that leads to the release of muscle fiber contents (myoglobin) into the bloodstream. Myoglobin is harmful to the kidney and often causes kidney damage.

Causes, incidence, and risk factors

When muscle is damaged, a protein called myoglobin is released into the bloodstream. It is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells. Rhabdomyolysis may be caused by any condition that damages skeletal muscle, especially injury.

Symptoms include:

Dark, red, or cola colored urine

Decreased urine production

General weakness

Muscle stiffness or aching (myalgia)

Muscle Weakness of the affected muscle
