Physiologic and Clinical Responses to Aerobic Exercise Training in Patients with Atrial Fibrillation

Parameter or Outcome	Response or Adaptation
Exercise capacity (eg, 6-min walk distance, peak oxygen uptake)	Modestly improved, 10%–15%
Skeletal muscle strength, endurance or histochemistry	Insufficient data
Clinical responses: AF burden (time in AF, ventricular rate at rest and during exercise)	Generally favorable responses, with less time in AF and lower ventricular rate at rest and during exercise
Health status or quality of life	Generally improved across most sub-measures
Clinical outcomes: mortality, rehospitalization	Insufficient data

Abbreviation: AF. atrial fibrillation.
