Exercising to death?

Exercising to death?

The warmer weather is on its way, and some of us will want to step up the exercise routine.  This is not necessarily a bad thing, but you can over-do it (yeah, I am mostly talking about you, Crossfitters). Having sore muscles after a work-out usually indicates you are building new muscle, however, being excessively tender and stiff after a workout may indicate you have over-trained and caused muscle death.  This condition is called exertional rhabdomyolysis, and it can put you in the hospital or even worse.

Called rhabdo for short, this potentially dangerous condition occurs when muscle fibers are working too hard, depleted of energy, and outpace oxygenation.  The fibers die thereby releasing their toxic contents (particularly myoglobin) into the bloodstream. These contents are not filtered well at the kidneys and can cause serious kidney injury.  If hospitalized with this condition, IVFs at high rates used to help clear the blockage caused by the myoglobin. In extreme cases, a person may have to receive hemodialysis (kidney replacement by a machine).    

It could be difficult for you know when your body reaches this point while exercising.  You must be diligent and know how your body behaves in strenuous exercise. Take breaks and hydrate extremely well.  If you do feel more sore than usual, stop the exercise immediately. If you are very tender and stiff, seek medical attention immediately at the closest ER.
