Can heavy strength training cause an increase of Muscle Enzymes?

Hey guys!

So I posted some convoluted message about calf pain that doesn’t seem to follow the standard patterns of a tweak or any kind of tendon issue. I ended up seeing my doc about it and tried to explain it as best I could and ended up giving him some blood to look at.

Turns out I have a “mild” elevation in muscle enzymes and a couple of other things like potassium. (Wish I had a pen and paper at the time). I did a little big of digging and that appears to be a possible indicator of muscular damage from basically anywhere in the body (heart, kidney etc), but could that also include the effect of training?

Side note: I’m giving some more blood this week and was told to avoid “strenuous” exercise. I kinda don’t want to avoid “strenuous” exercise based on everything I have l learnt here, so I probably wont. I also reviewed Jordan’s video on creatine and made sure to inform the doctor I was supplementing that, but as the video stated creatine and increase in muscle enzymes appear to be unrelated.

Yes, training can elevate enzymes like AST, CK, and (theoretically, transiently), potassium levels - though I still wouldn’t expect potassium to deviate much outside the normal range.

Figure I’ll ask here as it may be somewhat related:

Annual Physical (turn 41 later this year) came back with “elevated liver enzymes”. Specifically ALT is 2x normal range and Alkaline Phosphatase is a bit over the top of the “normal” range. Everything else is normal Would these be expected to be high as well? My doc is pretty stoked about having a “powerlifter” under his care, just not sure if there will be “surprises” for him.

Thanks a lot for all your work on this forum, youtube, and the podcasts. It’s really gotten me more engaged in the sport especially after repeated failed attempts at the end of NLP, and has flipped me over to living a healthier lifestyle.

Yes, those can be abnormal related to training as well, but would need to be repeated (with or without other testing), and potentially monitored over time.
