Do athletes have enlarged atria?
Multiple studies confirm that the left atrium (LA) is larger in an athletic population compared to non-athletic control groups. A meta-analysis of 54 studies comprising 7,189 elite athletes and 1,375 controls describes a 30% increase in LA volume index in athletes.

The following are ten key points on atrial enlargement in the athlete’s heart: The hemodynamic effects of intensive endurance exercise can result in the balanced enlargement of all four chambers of the heart.

A meta-analysis of 46 studies comprising 6,806 athletes established an upper limit of normal of 23cm 2 for the RA area in athletes, this is compared to 18cm 2 for the general population. Atrial enlargement appears related to volume overload due to the sustained increase in cardiac output during athletic training.
