Alanine Aminotransferase Concentrations in Elite Athletes

Authors: Giuseppe Banfi, PhD

Abstract

To the Editor:


I read the interesting paper published by Selden et al1,2 and the related correspondence. High values of alanine aminotransferase (ALT) in football players are linked with hypertension and metabolic syndrome, denying the expected healthy status of elite athletes. The topic is of particular interest because athletes are usually thought to be healthy by definition, but high levels of training workload and heavy psychophysical stress due to frequent and intense competitions could lead to modifications of biochemical and hematological parameters, which could show pathological values. Moreover, incorrect diet and unacknowledged behavior can induce unhealthy biochemical and metabolic data.
