Remind us, how high were the markers AST and ALT (or other markers if applicable), and did you take a few days off the gym before testing?

ALT and AST levels can remain elevated after strenuous exercise for seven days or more. Some factors that can greatly impact these levels are:
- Intensity and duration: The more intense and prolonged the exercise, the higher the peak levels of ALT and AST, and the longer these levels remain elevated.
- Untrained vs. trained athletes: Untrained athletes typically experience larger and more prolonged increases in these enzymes than their trained counterparts.
- Effect of training: As athletes train, their work capacity increases. This allows them to handle greater training loads/volumes without a proportional increase in ALT, AST, and Creatine Kinase (CK) levels.
- Type of exercise: While resistance training generally causes greater muscle damage, significant damage can also occur in ultra-endurance events, especially those with significant changes in elevation.
