A 3-year population-based study of exercise-related sudden cardiac arrest among 12- to 50-year-old Norwegians
(Peer reviewed; Journal article, 2023)Introduction: Regular exercise is associated with reduced risk of cardiovascular disease. Paradoxically, an increased risk of sudden cardiac arrest (SCA) is documented during or immediately after exercise and in athletes ... -
50 m freestyle in 21, 22 and 23 s: What differentiates the speed curve of world-class and elite male swimmers?
(Peer reviewed; Journal article, 2021)We examined the association between 50 m freestyle performance (50FS) and average speed (AS), peak speed (PS), minimum speed (MS) and intracyclic speed variation (ISV) and compared the speed curves from swimmers with ... -
A Controlled Comparison of Microfracture, Debridement, and No Treatment of Concomitant Full-Thickness Cartilage Lesions in Anterior Cruciate Ligament-Reconstructed Knees: A Nationwide Prospective Cohort Study From Norway and Sweden of 368 Patients With 5-Year Follow-up
(Journal article; Peer reviewed, 2018)Background: The effect of microfracture (MF) or surgical debridement of concomitant full-thickness cartilage lesions in anterior cruciate ligament–reconstructed knees on patient-reported outcomes remains to be ... -
A longitudinal analysis of the relationships of physical activity and body fat with nerve growth factor and brain-derived neural factor in children
(Journal article; Peer reviewed, 2018)A longitudinal analysis of the relationships of physical activity and body fat with nerve growth factor and brain-derived neural factor in children -
A new training assessment method for alpine ski racing: Estimating center of mass trajectory by fusing inertial sensors with periodically available position anchor points
(Journal article; Peer reviewed, 2018)In this study we present and validate a method to correct velocity and position drift for inertial sensor-based measurements in the context of alpine ski racing. Magnets were placed at each gate and their position determined ... -
A pedometer-based walking intervention in 45- to 75-year-olds, with and without practice nurse support: The PACE-UP three-arm cluster RCT

A valid and reliable method to measure jump-specific training and competition load in elite volleyball players
(Journal article; Peer reviewed, 2018)Purpose: Use of a commercially available wearable device to monitor jump load with elite volleyball players has become common practice. The purpose of this study was to evaluate the validity and reliability of this device, ... -
Absolute intensity thresholds for tri-axial wrist and waist accelerometer-measured movement behaviors in adults
(Peer reviewed; Journal article, 2023)Aim: This study was aimed to: (1) compare raw triaxial acceleration data from GENEActiv (GA) and ActiGraph GT3X+ (AG) placed on the non-dominant wrist; (2) compare AG placed on the non-dominant and dominant wrist, and ... -
Accelerometer epoch setting is decisive for associations between physical activity and metabolic health in children
(Peer reviewed; Journal article, 2019)When analysing physical activity (PA) levels using accelerometry, the epoch setting is critical to capture intensity-specific PA correctly. The aim of the present study was to investigate the PA intensity signatures related ... -
Accelerometer-measured physical activity and sedentary time in a cohort of US adults followed for up to 13 years: The influence of removing early follow-up on associations with mortality
(Peer reviewed; Journal article, 2020)Background: Observational studies linking physical activity with mortality are susceptible to reverse causation bias from undiagnosed and prevalent diseases. Researchers often attempt to deal with reverse causation bias ... -
Accessibility, agency, and trust: A study about equestrians' (online) learning repertoires
(Peer reviewed; Journal article, 2022)Todays' online media landscape facilitates communication on how sports practitioners can develop in their sport. Hence, sports and educational institutions need to recognize the increased role of the individual as “a ... -
