Elite Ice Hockey Goalkeepers Have a High Prevalence of Hip and Groin Problems Associated With Decreased Sporting Function: A Single-Season Prospective Cohort Study
(Peer reviewed; Journal article, 2019)Background: The modern style of goalkeeping in ice hockey is thought to predispose athletes to hip and groin problems. However, little is known about the magnitude of these problems in elite goalkeepers. Purpose: To describe ... -
How many days are needed to estimate wrist-worn accelerometry-assessed physical activity during the second trimester in pregnancy?
(Peer reviewed; Journal article, 2019)Background: Objective methods to measure physical activity (PA) can lead to better cross-cultural comparisons, monitoring temporal PA trends, and measuring the effect of interventions. However, when applying this technology ... -

(Peer reviewed; Journal article, 2019)Low-carbohydrate-high-fat (LCHF) diets are efficient for weight loss, and are also used by healthy people to maintain bodyweight. The main aim of this study was to investigate the effect of 3-week energy-balanced LCHF-diet, ... -
Physical activity levels in adults and elderly from triaxial and uniaxial accelerometry: The Tromsø Study
(Peer reviewed; Journal article, 2019)Introduction: Surveillance of physical activity at the population level increases the knowledge on levels and trends of physical activity, which may support public health initiatives to promote physical activity. Physical ... -
Substituting prolonged sedentary time and cardiovascular risk in children and youth: a meta-analysis within the International Children’s Accelerometry database (ICAD)
(Peer reviewed; Journal article, 2019)Background: Evidence on the association between sitting for extended periods (i.e. prolonged sedentary time (PST)) and cardio-metabolic health is inconsistent in children. We aimed to estimate the differences in cardiometabolic ... -
