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. ... -
