Blood work for runners (Read 1684 times)

    These annual check-ups often include the obligatory body fat measurement, which is (or so I've read) impacted by hydration levels.  A 2 hr run prior to your appointment may leave you somewhat dehydrated and throw off this metric.  Just a thought.

      I've got a physical next week and want to get the fasting blood work out of the way in the AM. Is it okay to do a 90-120 minute run before, say about an hour or so?

       

      Heh. I did this, and then waited, and waited, and...almost passed out. Had to leave and do it another day.

        Just to relay the experience. I ran a hard 12 the morning I was to have bloodwork done. They made me repeat the bloodwork a month later and told me not to overly exert myself 24 hours before the test. I guess some liver function tests were a little screwy and there was blood in my urine. follow up was normal but I guess hard running can screw things up a bit. 

         

        The same thing happened to me. I got a blood test as part of my physical and the AST levels came back elevated. From limited research I have done, I've heard this can read high from muscle breakdown after hard exercise. I believe the ALT levels are the ones that are more indicative of liver damage.  In any case, I have to get retested which I hope the AST levels are down but I doubt they will be if it's due to running.

          My liver enzymes came back borderline troubling - which jogged my memory of the previous night's pitcher of margaritas. Apparently fasting the morning of wasn't good enough. Wink

          I don't half-ass anything

            Sounds like you had little memory of that night. Smile

            Well at least someone here is making relevance to the subject.

              But what about the non-drinkers? I don't drink alcohol (anymore) and I had elevated liver enzymes. I wonder how many non-drinking runners have this lab result?
