Left atrial volume in elite athletes: A meta-analysis of echocardiographic studies.

Our meta-analysis suggests that the adaptation of LA to intensive physical training in elite athletes is characterized by a marked increase in LAVI; LA dilation is more pronounced in the subgroup of high-dynamic/high-static trained athletes. The functional and clinical implications related to advanced LA dilation in athletes and particularly in those engaged in high-dynamic/high-static disciplines deserve further investigations.
