Relation between body mass index and serum aminotransferases concentrations in professional athletes

Reference intervals commonly used for evaluating and interpreting laboratory values obtained in athletes are the same used in the general population. Aminotransferases (aspartate aminotransferase [AST], and alanine aminotransferase [ALT]) are commonly analyzed in serum for evaluating hepatic function. Some studies in the general population and in blood donors testified that ALT concentrations clearly correlated with weight and body mass.
