Patients having Aerobic Interval Training (AIT) for 12 weeks experienced fewer and less severe incidence of atrial fibrillation.Study Outcome

"In the current issue of Circulation, Malmo et al11 provide the results of their randomized controlled trial, in which they compared a popular form of high-intensity exercise, aerobic interval training (AIT), with a control group who were not prescribed exercise. The authors’ randomised 51 AF patients referred for catheter ablation, to exercise or no-exercise over 12 weeks, and recorded AF burden from implantable loop recorders as the primary study outcome. Notably, the authors demonstrate a significant reduction in AF burden in the exercise group, where the mean time in AF declined from 8.1 to 4.8%, with no significant change in the control group. Of the exercise group, 38% of patients experienced a decline in their arrhythmia burden compared to only 20% of the control group. Increased AF burden was more common in the control patients (64%) than in the exercise group (12%). Importantly, patients in the exercise group experienced fewer and less severe symptoms following the intervention, with no concomitant change in the control group. Compared to controls, patients randomised to exercise also increased their peak oxygen consumption (VO2peak), cardiac function and quality of life, whilst improving body mass index and blood lipids."
