Key result
Endurance training shows a dose-dependent link to AF risk, driven by atrial thickening and fibrosis.
Why the study?
Long-lasting vigorous sports engagement may cause AF, but the relationship between endurance training, exercise intensity/duration, and the triggers leading to impaired cardiac function and AF remains complex.

May warrant AF monitoring in high-volume endurance athletes; leaves open optimal training thresholds and preventive interventions.
Does endurance training increase the risk of atrial fibrillation in athletes?
This scoping review highlights the structural and autonomic mechanisms by which long-term endurance training increases the risk of atrial fibrillation in athletes.
Lobo et al. (2023) conducted a review in Atrial Fibrillation (n=115). Endurance training vs. Sedentary lifestyle or moderate physical activity was evaluated on Risk of atrial fibrillation. Endurance training exhibits a dose-response relationship with the risk of atrial fibrillation, driven by morphological and electrophysiological cardiac changes such as increased atrial thickness and myocardial fibrosis.
