Key result
Exercise training habits show no link to AF incidence in veteran male endurance athletes.
Why the study?
Endurance athletes have an increased prevalence of AF, but no long-term studies have simultaneously tracked exercise activity using wearable technology combined with continuous cardiac monitoring in veteran athletes.
Does prospective exercise training volume, intensity, or timing correlate with the incidence of atrial fibrillation in veteran male endurance athletes?
Population
106 healthy male endurance athletes aged ≥ 50y exercising ≥ 10h/week for ≥ 15y
Comparison
Exercise tracking using CETDs correlated with ILR-detected AF incidence and timing
Design
Prospective observational cohort study
Follow-up
Median 3.4 years (IQR 3.2 - 3.5 years)

Supports AF monitoring consideration in veteran male endurance athletes; leaves open exercise causality in observational data.
Observational (n=106)
Does prospective exercise training volume, intensity, or timing correlate with the incidence of atrial fibrillation in veteran male endurance athletes?
In veteran male endurance athletes, the onset of atrial fibrillation appears related to lifetime competitive exercise exposure, age, and blood pressure rather than recent prospective exercise training habits.
Javed et al. (2026) conducted an observational in Atrial fibrillation (n=106). Prospective exercise training habits (volume, intensity, type) vs. Different levels of exercise exposure was evaluated on Six minutes of atrial fibrillation detected by implantable loop recorder. In veteran male endurance athletes, prospective exercise training habits did not influence the incidence of atrial fibrillation (15.1% overall) over a median 3.4 years of follow-up.
