Transaminase levels and vigorous exercise.

MS Healthy individuals have normal levels of transaminase enzymes. Although the levels that constitute “normal” are currently under debate, most people who are healthy have levels that are recognizably within the normal range. However, just as these markers do not discriminate among liver diseases, they do not discriminate among several different sources of inflammation. Thus, raised levels can be traced to muscular inflammation as well as hepatic inflammation. People who exercise heavily (eg, weight lifters, marathon runners, soldiers who perform heavy-duty labor) can have abnormal transaminase levels, as can those suffering muscular trauma, such as myocardial infarction or even surgery in which some muscles are cut. The normal repair process in these cases engenders inflammation and raises transaminase levels. G&H Do ALT and AST react to hepatic and muscular inflammation similarly?
