Concurrent Training in Patients Undergoing Atrial Fibrillation Ablation.

12 weeks of concurrent training, which is understood as a combination of strength and aerobic exercises, not necessarily in the same training session. The weekly frequency will be 3 times per week. The aerobic component of the session will last between 30 and 50 minutes (increasing as the weeks go by) and the strength work will be made up of 8 exercises (3 upper body and 5 lower body). The intensity of the training will be individualized and always moderate.
