Effect of 3 Years of Exercise on Development of Atrial Fibrillation
This is a substudy of "Generation 100". In that study, 4000 healthy persons between 70 and 75 will be randomised do moderate intensity, high intensity or control group, with 3 years of exercise. The investigators will follow these persons and register all who develop atrial fibrillation during these 3 years, and at follow-up after ended intervention to see if there is differences in the number of persons who develop atrial fibrillation in the 3 groups.
