Psychosocial predictors of drop-out from organised sport: A prospective study in adolescent soccer
(Peer reviewed; Journal article, 2022)In recent years an increased drop-out rate in adolescents’ soccer participation has been observed. Given the potentially adverse consequences of drop-out from soccer, more information about risk factors for drop-out is ... -
Public employees in South-Western Norway using an e-bike or a regular bike for commuting: A cross-sectional comparison on sociodemographic factors, commuting frequency and commuting distance
(Peer reviewed; Journal article, 2019)Large-scale analyses on the travel behavior of e-bikes are scarce, and current knowledge regarding who the e- bike owners are is inconsistent. Also, commuters represent a relevant user group with an unexploited potential. ... -
Public opinion in Japan and the UK on issues of fairness and integrity in sport: implications for anti-doping policy
(Peer reviewed; Journal article, 2020)The continuing challenge of achieving compliance with the World Anti-Doping Code had led WADA to place an increasing emphasis on strengthening anti-doping values. Education was given a much higher and clearer profile in ... -
Pulmonary ventilation and gas exchange during prolonged exercise in humans: Influence of dehydration, hyperthermia and sympathoadrenal activity
(Peer reviewed; Journal article, 2023)The mechanisms driving hyperthermic hyperventilation during exercise are unclear. In a series of retrospective analyses, we evaluated the impact of combined versus isolated dehydration and hyperthermia and the effects of ... -
Qualitative and quantitative anatomy of the human quadriceps tendon in young cadaveric specimens
(Peer reviewed; Journal article, 2021)Background: A detailed understanding of the anatomy of the quadriceps tendon (QT) is clinically relevant, owing to its increased use as a graft in anterior cruciate ligament reconstruction. Purpose: To qualitatively and ... -
Quantitative and Qualitative Assessment of the Posterior Medial Meniscus Anatomy : Defining Meniscal Ramp Lesions
(Journal article; Peer reviewed, 2018)Background: Meniscal ramp lesions have been defined as a tear of the peripheral attachment of the posterior horn of the medial meniscus (PHMM) at the meniscocapsular junction or an injury to the meniscotibial attachment. ... -
Race analysis in competitive swimming: A narrative review
(Peer reviewed; Journal article, 2020)Researchers have quantified swimming races for several decades to provide objective information on race strategy and characteristics. The purpose of the present review was to summarize knowledge established in the literature ... -
Radial and oblique impact testing of alpine helmets onto snow surfaces
(Peer reviewed; Journal article, 2023)Recent studies have found that alpine helmets reduce the risk of focal injuries associated with radial impacts, which is likely due to current alpine helmet standards requiring helmets to be drop-tested on flat anvils with ... -
A randomized controlled trial of a blended physical literacy intervention to support physical activity and health of primary school children
(Peer reviewed; Journal article, 2022)Background: The concept of physical literacy (PL) has been advocated as the need to create environments fostering sustainable engagement in PA. This study adopted ecological approach to evaluate the effectiveness of a ... -
Randomized trial of cardiovascular prevention in Norway combining an in-hospital lifestyle course with primary care follow-up: The Hjerteløftet study
(Peer reviewed; Journal article, 2022)Aims: Cardiovascular risk factor control is suboptimal in Europe, including Norway. The present study examined the efficacy of a multimodal primary prevention intervention programme based on the existing Norwegian health ... -
Ranking robot-assisted surgery skills using kinematic sensors
(Peer reviewed; Journal article, 2019)Assessing surgical skills is an essential part of medical performance evaluation and expert training. Since it is typically conducted as a subjective task by individuals, it may lead to misinterpretations of the skill ... -
Ranking surgical skills using an attention-enhanced Siamese network with piecewise aggregated kinematic data
(Peer reviewed; Journal article, 2022)Purpose: Surgical skill assessment using computerized methods is considered to be a promising direction in objective performance evaluation and expert training. In a typical architecture for computerized skill assessment, ... -
Rapid radiochemical filter paper assay for determination of hexokinase activity and affinity for glucose-6-phosphate
(Peer reviewed; Journal article, 2019)Glucose phosphorylation by hexokinase (HK) is a rate-limiting step in glucose metabolism. Regulation of HK includes feedback inhibition by its product glucose-6-phosphate (G6P) and mitochondria binding. HK affinity for G6P ... -
Rate of force development relationships to muscle architecture and contractile behavior in the human vastus lateralis
(Peer reviewed; Journal article, 2022)In this study, we tested the hypotheses that (i) rate of force development (RFD) is correlated to muscle architecture and dynamics and that (ii) force–length–velocity properties limit knee extensor RFD. Twenty-one healthy ... -
Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity
(Peer reviewed; Journal article, 2019)This review re‐examines the use of accelerometer and oxygen uptake data for the assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency ... -
Readiness for return to sport in non-surgically treated patients with anterior cruciate ligament injury following a public municipal rehabilitation program
(Peer reviewed; Journal article, 2022)Objectives: To investigate the proportion of patients that pass a return to sport (RTS) test battery and assess changes in patient-reported outcomes and lower extremity muscle strength following three months of exericse-based ... -
