Key result
Leisure-time exercise >5 hours/week at age 30 increased atrial fibrillation risk (RR 1.19; 95% CI 1.05-1.36), whereas walking/bicycling >1 hour/day at age 60 decreased risk (RR 0.87; 95% CI 0.77-0.97).
Why the study?
Does the level and type of physical activity at different ages affect the risk of developing atrial fibrillation in men?
Cohort (n=44,410)
Does the level and type of physical activity at different ages affect the risk of developing atrial fibrillation in men?
Relative Risk: 1.19 (95% CI 1.05–1.36)
Intense leisure-time exercise at a younger age is associated with an increased risk of atrial fibrillation in men, whereas moderate activity like walking or bicycling at an older age is associated with a decreased risk.

Exercise patterns showed age-specific AF associations in men; hypothesis-generating and should not yet change practice.
Drca et al. (2014) conducted a cohort in atrial fibrillation (n=44,410). Leisure-time exercise >5 h/week at age 30 vs. <1 h/week was evaluated on development of atrial fibrillation (RR 1.19, 95% CI 1.05 to 1.36). Leisure-time exercise >5 hours/week at age 30 increased atrial fibrillation risk (RR 1.19; 95% CI 1.05-1.36), whereas walking/bicycling >1 hour/day at age 60 decreased risk (RR 0.87; 95% CI 0.77-0.97).
