Does endurance sport harm your heart?

We investigate the connection between high levels of exercise and abnormal heart rhythm or arrhythmia.

Exercise is good for you in all kinds of ways, there is no medicine like it to prevent a whole range of illnesses. But for some endurance athletes, exercise also comes with increased risk of a heart condition called atrial fibrillation.

We look for the right way to think about the risks around exercise.
