Key result
Regular exercise is associated with reduced incident and recurrent atrial fibrillation, although a threshold may exist beyond which extreme cardiorespiratory fitness increases risk.
Why the study?
Regular exercise reduces incident and recurrent AF, but whether a threshold exists beyond which exercise and higher cardiorespiratory fitness become harmful remains an open question.
Is there a threshold beyond which high cardiorespiratory fitness and exercise increase the risk of atrial fibrillation and stroke?
Is there a threshold beyond which high cardiorespiratory fitness and exercise increase the risk of atrial fibrillation and stroke?
The article discusses the potential threshold at which high cardiorespiratory fitness and exercise may become harmful regarding the risk of atrial fibrillation and stroke.
May support moderate exercise counseling for AF risk reduction; leaves open an upper fitness threshold for prospective validation.

Myrstad et al. (2025) studied this question. Regular exercise is associated with reduced incident and recurrent atrial fibrillation, although a threshold may exist beyond which extreme cardiorespiratory fitness increases risk.
