Recurrent lateral patella dislocation affects knee function as much as ACL deficiency – however patients wait five times longer for treatment
(Peer reviewed; Journal article, 2019)Background: Surgical treatment of young patients with recurrent lateral patella dislocation (RLDP) is often recommended because of loss of knee function that compromises their level of activity or even their daily life ... -
Reducing lumbar flexion in a repetitive lifting task: Comparison of leukotape and kinesio tape and their effect on lumbar proprioception
(Peer reviewed; Journal article, 2023)Rigid leukotape applied to the skin of the trunk dorsum, superficial to the lumbar paraspinals, has been shown to reduce lumbar flexion in repetitive lifting, with the potential to reduce the risk of injury in jobs requiring ... -
Referee efficacy in the context of Norwegian soccer referees – A meaningful construct?
(Journal article; Peer reviewed, 2018)Objectives: The purpose of this study was two-fold. Firstly, to examine the measurement/factorial validity and invariance of the Referee Self-Efficacy Scale (REFS) among Norwegian soccer referees. Secondly, extending scale ... -
Reference values for wrist-worn accelerometer physical activity metrics in England children and adolescents
(Peer reviewed; Journal article, 2023)Background: Over the last decade use of raw acceleration metrics to assess physical activity has increased. Metrics such as Euclidean Norm Minus One (ENMO), and Mean Amplitude Deviation (MAD) can be used to generate metrics ... -
Refleksjoner over profesjonsutvikling fra lærerspesialiststudenter i kroppsøving
(Peer reviewed; Journal article, 2023)Formålet med lærerspesialistordningen og utdanningen var å gi lærere faglige utviklingsmuligheter og å styrke det kollektive profesjonsfellesskapet. I denne artikkelen løfter vi frem hvordan ti lærerspesialiststudenter i ... -
Regulation of Nrf2/Keap1 signalling in human skeletal muscle during exercise to exhaustion in normoxia, severe acute hypoxia and post-exercise ischaemia: Influence of metabolite accumulation and oxygenation
(Peer reviewed; Journal article, 2020)The Nrf2 transcription factor is induced by reactive oxygen and nitrogen species and is necessary for the adaptive response to exercise in mice. It remains unknown whether Nrf2 signalling is activated by exercise in human ... -
A relational perspective on students' experiences of participation in an ‘Interest-based physical education’ programme
(Peer reviewed; Journal article, 2021)While many students participate autonomously in physical education (PE), research shows that students who do not participate in leisure sport are less likely to perceive PE positively. Attempting to optimise the reciprocal ... -
The relationship between selected load-velocity profile parameters and 50 m front crawl swimming performance
(Peer reviewed; Journal article, 2021)The purpose of the present study was to establish relationships between sprint front crawl performance and a swimming load-velocity profile. Fourteen male national-level swimmers performed 50 m front crawl and semi-tethered ... -
Relationship between stability and variability ofthe core in dynamic reaching tasks
(Peer reviewed; Journal article, 2019)Core stability is important to many functional and athletic tasks. Motion variability has been proposed as a measure to characterize core stability. Based on motor learning theories, the current study hypothesized that ... -
The relationship between the perception of reduced performance due to injury or illness and basic psychological need satisfaction in Norwegian youth elite handball: A cross-lagged panel analysis
(Peer reviewed; Journal article, 2022)This study investigated the relationship between perceived reduction in performance due to injury or illness (RPII) and basic psychological need satisfaction in youth elite handball. Participants were 174 elite youth ... -
The relationship between the relative age effect and performance among athletes in World Handball Championships
(Peer reviewed; Journal article, 2020)This study examines the relative age effect (RAE) and its impact on the performance of elite male (n = 3,358) and female (n = 3,273) handball players in the U-19 (n = 2,188), U-21 (n = 2,031), and senior (n = 2,412) ... -
The relative age effect in German 11- to 18-year-old male and female swimmers
(Peer reviewed; Journal article, 2020)Relatively older athletes have a greater probability of being selected and subsequently exposed to a higher level of coaching, training and other talent-promoting factors. Grouping by chronological age is, therefore, ... -
The relative age effect on competition performance of Spanish international handball players: A longitudinal study
(Peer reviewed; Journal article, 2021)Background: Competitive success is the ultimate objective of elite professional sport organisations. Relative age effects (RAE) impact athlete selection processes in the short and long-term performance. The aims of this ... -
Relative Body Weight and Standardised Brightness-Mode Ultrasound Measurement of Subcutaneous Fat in Athletes: An International Multicentre Reliability Study, Under the Auspices of the IOC Medical Commission
(Peer reviewed; Journal article, 2019)Introduction: Fat is a metabolic fuel, but excess body fat is ballast mass, and therefore, many elite athletes reduce body fat to dangerously low levels. Uncompressed subcutaneous adipose tissue (SAT) thickness measured ... -
Reliability of a semi-tethered front crawl sprint performance test in adolescent swimmers
(Peer reviewed; Journal article, 2023)This study aimed to evaluate the test-retest reliability of a sprint performance test with semi-tethered front crawl swimming to indirectly assess the current potential to perform at maximal anaerobic effort in adolescent ... -
Reliability of load-velocity profiling in front crawl swimming
(Peer reviewed; Journal article, 2020)The purposes of this study were to establish test-retest reliability of calculating load-velocity profiles in front crawl swimming using five and three different external loads, and if outcome results were comparable between ... -
Reliability of maximum oxygen uptake in cardiopulmonary exercise testing with continuous laryngoscopy
(Peer reviewed; Journal article, 2021)Aims: A cardiopulmonary exercise test (CPET) is the gold standard to evaluate symptom-limiting exercise intolerance, while continuous laryngoscopy performed during exercise (CLE) is required to diagnose exercise-induced ... -
