Birkebeiner Ageing Study (project description) - project description

The aim of this project is to study ageing, disease and functional decline among the fittest elderly people in Norway.


The Birkebeiner Ageing Study started in 2009 when around 600 participants of the 54 kilometer Birkebeiner cross-country ski race were included. The participants were aged between 65 and 90 years and have given consent to be contacted for regular follow-up surveys. Life-style habits and physical and mental health have been investigated by questionnaires.

In 2012 around 5000 individuals aged between 50 and 90 were included in a project with the aim to study associations between long-term endurance sport practice and risk of atrial fibrillation. Half of the participants of this project had previously completed the Birkebeiner cross-country ski race, while the other half had previously been participants in a healthy survey in Oslo, Health and Environment in Oslo.
