Does High-Intensity Endurance Training Increase the Risk of Atrial Fibrillation?: A Longitudinal Study of Left Atrial Structure and Function [Original Articles]

Conclusions:
Changes in LA structure, LA mechanical function, and left ventricular remodeling occurred after 10 months of exercise but without significant change in atrial electrical activity. A longer duration of training may be required to induce electrical changes thought to cause atrial fibrillation in middle-aged endurance athletes.
