    muscle enzyme blood work

    I recently had my blood work done and the CPK (muscle enzyme) was 1042
    the normal range 35 - 230 U/L, My doctor said it was from lifting heavy weight alot.

    Does anyone else know if their CPK is that high?

    Never had that checked out. I guess it makes sense though, CPK is creatine phosphokinase if I'm not mistaken, and elevated levels seem like a logical response to weight training.

    I only take 5 grams of creatine pre-workout, the doc said that he didn't the supplement creatine has anything to do with it. He said he would be concerned if he didn't know I was a BB'er, that high of cpk is usually associated with damage due to heart attack, thats why I was wondering if any of you know what your CPK level is.

    I'm a medical technologist by trade, so this is part of what I do. CK (or CPK) is normally elevated from lifting heavy weights. It will also be elevated from a fall. Anytime muscle tissue is damaged, CK will be affected. The CK isoenzymes, are specific to muscle types. CK-MB is specific for heart muscle, and is used to diagnose heart attacks. CK will remain elevated for up to 7 days depending on how much muscle is damaged. This is a good thing, when you lift, you want to damage muscle, so the body rebuilds it stronger.
