He is first author in the paper “Aerobic Interval training reduces the burden of atrial fibrillation in the short term: A randomized trial” recently published in Circulation. In this study, 51 persons with non-permanent atrial fibrillation (AF) were randomized either to high intensity interval training (four 4-minute intervals at 85-95% of peak heart) rate three times a week for 12 weeks or a control group (continuing their earlier exercise habits). Minutes of AF each day was monitored continuously with an implanted recorder. In addition cardiac function, exercise capacity, lipid status, quality of life and AF symptoms were assessed.

UTFORSK – Collaboration makes us better

Fellesbilde UTFORSK Sao PauloThe UTFORSK project is a collaboration between CERG at NTNU and the University of Sao Paulo. Our primary aim with the project is to promote exchange of staff and students for a variety of activities such as collaboration in research projects, joint teaching, workshops and seminars in the field of Exercise Science. Last week we organized our first Seminar in Sao Paulo, Brazil. The goals of the Seminar were to summarize the research projects in collaboration and also to build new partnerships in research that will last beyond the duration of the project.

High fitness reduces risk of atrial fibrillation

Two women running outdoorOverweight, hypertension, diabetes and sleep apnea increases the risk of developing atrial fibrillation (AF). Interventions aimed at these risk factors are known to reduce the risk and improve the outcome for most cardiovascular diseases. However, there has been lacking knowledge on the effect of such interventions on AF, and there has been considerable attention on the finding that large amounts of endurance exercise increases the risk of developing AF. Recent years, there have been published some studies examining this topic.
