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 ... -
Recommendations for determining the validity of consumer wearable and smartphone step count: Expert statement and checklist of the INTERLIVE network
(Peer reviewed; Journal article, 2020)Consumer wearable and smartphone devices provide an accessible means to objectively measure physical activity (PA) through step counts. With the increasing proliferation of this technology, consumers, practitioners and ... -
Recommendations for determining the validity of consumer wearable heart rate devices: Expert statement and checklist of the INTERLIVE Network
(Peer reviewed; Journal article, 2021)Assessing vital signs such as heart rate (HR) by wearable devices in a lifestyle-related environment provides widespread opportunities for public health related research and applications. Commonly, consumer wearable devices ... -
Recommendations for determining the validity of consumer wearables and smartphones for the estimation of energy expenditure: Expert statement and checklist of the INTERLIVE network
(Peer reviewed; Journal article, 2022)Background: Consumer wearables and smartphone devices commonly offer an estimate of energy expenditure (EE) to assist in the objective monitoring of physical activity to the general population. Alongside consumers, healthcare ... -
Recovery from Achilles Tendon Repair: A Combination of Postsurgery Outcomes and Insufficient Remodeling of Muscle and Tendon
(Peer reviewed; Journal article, 2021)Introduction: Achilles tendon rupture (ATR) patients have persistent functional deficits in the triceps surae muscle–tendon unit (MTU). The complex remodeling of the MTU accompanying these deficits remains poorly understood. ... -
Recovery of pelvic floor muscle strength and endurance 6 and 12 months postpartum in primiparous women: A prospective cohort study
(Peer reviewed; Journal article, 2022)Introduction and hypothesis: To date there has been scant knowledge on the natural recovery of the pelvic floor muscles (PFMs) after childbirth. The aims of the present study were to investigate whether PFM variables at 6 ... -
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
