Key result
Extreme prolonged exercise linked to increased AF risk, while general exercise remains protective.
Why the study?
The relationship between physical activity and atrial fibrillation is unclear, with evidence suggesting both risk and protective effects of exercise on AF incidence.
Does physical activity influence the incidence of atrial fibrillation in adults?
Population
Adults including general population and those engaging in extreme/prolonged exercise
Comparison
Extreme and prolonged exercise versus general physical activity
Design
Review of studies on exercise and atrial fibrillation

May warrant caution with extreme endurance exercise in AF-susceptible adults; leaves open optimal dosing and requires prospective trials.
Does physical activity influence the incidence of atrial fibrillation in adults?
The relationship between exercise and atrial fibrillation is complex, with moderate exercise generally being protective while extreme, prolonged exercise may increase the risk of developing the arrhythmia.
Shamloo et al. (2018) conducted a review in Atrial fibrillation. Exercise was evaluated on Incidence of atrial fibrillation. Extreme and prolonged exercise may act as a risk factor for the onset of atrial fibrillation, whereas exercise in the general population can be a protective factor.
