Past studies have reported that walking reduces the risk of atrial fibrillation (AF) by 48%,
whereby running increased AF risk by 53%. A resent study (linked below) found "the risk for cardiac arrhythmias was similar in walkers and runners who
expended comparable METhr/d during structured exercise. We found no
significant risk increase for self-reported cardiac arrhythmias
associated with running distance, exercise intensity, or marathon
participation. Rhythm abnormalities were based on self-report,
precluding definitive categorization of the nature of the rhythm
disturbance. However, even if the runners’ arrhythmias include sinus
bradycardia due to running itself, there was no increase in arrhythmias
with greater running distance."

Possible super runners?
The article linked below shows that overexpression of phosphoenolpyruvate carboxykinase (GTP) (PEPCK-C) in skeletal muscle leads to supercharged mice capable of running long distances and having a great longevity. What is there to stop humans from having gene therapy to increase expression of (PEPCK-C) in skeletal muscles and how do you ensure that this will not happen or happening. Good by EPO and welcome the new wave of performance enhancement, gene therapy.
