    • Rationale and design of the Birkebeiner Ageing Study – a prospective cohort study of older endurance athletes 

      Myrstad, Marius; Johansen, Kristoffer Robin; Sørensen, Eivind; Ranhoff, Anette Hylen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-13)
      Background - While regular physical activity is associated with reduced mortality and morbidity in general populations, health outcomes and functional capacity related to upholding strenuous endurance exercise beyond the age of 65 years are only sparsely studied. The aim of this study is to assess associations of prolonged strenuous endurance sport practice with ageing, functional decline, morbidity ...
    • Risk of atrial fibrillation and stroke among older men exposed to prolonged endurance sport practice: a 10-year follow-up. The Birkebeiner Ageing Study and the Tromsø Study

      <p><b> Aims</b> Endurance sport practice is associated with a high prevalence of atrial fibrillation (AF), which increases the risk of stroke in the general population. However, stroke risk in endurance athletes with AF is sparsely investigated. Most studies have been limited by design and are largely restricted to younger and middle-aged populations. Thus, we aimed to investigate AF and stroke ...
    • Ten-year mortality among older male recreational endurance athletes in the Birkebeiner Aging Study in comparison with older men from the Tromsø Study

      Background: Physical activity (PA) is associated with reduced mortality. However, whether there is an added benefit of long-term endurance training is unclear. Thus, we aimed to examine 10-year mortality in older male endurance athletes compared with an older male general population. <p><p>Method: Male athletes (n=503) participating in an annual long-distance ski race (median years of participation: ...
