Assessing day-to day reliability of the Newtest 2000 Sprint Timing system
(Journal article; Peer reviewed, 2011)The purpose of the present study was to assess the day-to-day test-retest reliability of the Newtest 2000 - sprint timing system. The reliability of the system was assessed by testing 52 Physical Education students. All ... -
The association between gastrointestinal injury, complaints, and food intake in 60-km ultramarathon runners
(Peer reviewed; Journal article, 2022)We aimed to assess the association between gastrointestinal (GI) injury, complaints, and food intake in 60-km ultramarathon runners. Thirty-three ultramarathon runners provided pre- and post-race blood samples for assessment ... -
Bone health in Norwegian female elite runners: A cross-sectional, controlled study
(Peer reviewed; Journal article, 2023)Objective: The primary objective was to compare bone mineral density (BMD) in Norwegian female elite long-distance runners with a control group of inactive females. Secondary objectives were to identify cases of low BMD, ... -
Crossing the golden training divide: The science and practice of training world-class 800- and 1500-m runners
(Peer reviewed; Journal article, 2021)Despite an increasing amount of research devoted to middle-distance training (herein the 800 and 1500 m events), information regarding the training methodologies of world-class runners is limited. Therefore, the objective ... -
Distinct muscle-tendon interaction during running at different speeds and in different loading conditions
(Peer reviewed; Journal article, 2019)The interaction between the Achilles tendon and the triceps surae muscles seems to be modulated differently with various task configurations. Here we tested the hypothesis that the increased forces and ankle joint work ... -
Effects of heavy strength training on running performance and determinants of running performance in female endurance athletes
(Journal article; Peer reviewed, 2016-03-08)Purpose: The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized ... -
Exercise economy in skiing and running
(Journal article; Peer reviewed, 2014-01-24)Substantial inter-individual variations in exercise economy exist even in highly trained endurance athletes. The variation is believed to be determined partly by intrinsic factors. Therefore, in the present study, we ... -
Exploring the relationship between adiposity and fitness in young children
(Journal article; Peer reviewed, 2016-09)Objective: High levels of cardiorespiratory fitness (CRF) may attenuate the association between excessive adiposity and the risks of cardiovascular and metabolic disease. The purpose of this study was to stratify children ... -
Maximal Heart Rate for Swimmers
(Peer reviewed; Journal article, 2019)The main purpose of this study was to identify whether a different protocol to achieve maximal heart rate should be used in sprinters when compared to middle-distance swimmers. As incorporating running training into swim ... -
Medial gastrocnemius muscle fascicles shorten throughout stance during sprint acceleration
(Peer reviewed; Journal article, 2021)The compliant nature of distal limb muscle-tendon units is traditionally considered suboptimal in explosive movements when positive joint work is required. However, during accelerative running, ankle joint net mechanical ... -
Performance in youth track and field is associated with birth quartile: A register-based study among athletes in Norway from 10 years to senior level
(Peer reviewed; Journal article, 2022)Introduction: Earlier studies have demonstrated that the oldest in a competition class are more likely to succeed than the youngest, a phenomenon called relative age effect (RAE). Track and field give us an opportunity to ... -
Running with Dewey: is it possible to learn to enjoy running in High School Physical Education?
(Journal article; Peer reviewed, 2013-06-06)This study is based on an action research project labelled ‘Running with Dewey’ implemented in a second-year High School Physical Education (PE) class. The purpose of the project was to analyse students’ response to a ... -
Sport-specific capacity to use elastic energy in the patellar and Achilles tendons of elite athletes
(Journal article; Peer reviewed, 2017)Introduction: During running and jumping activities, elastic energy is utilized to enhance muscle mechanical output and efficiency. However, training-induced variations in tendon spring-like properties remain under-investigated. ... -
Sprint conditioning of junior soccer players: effects of training intensity and technique supervision
(Journal article; Peer reviewed, 2015-03-23)The aims of the present study were to compare the effects of 1) training at 90 and 100% sprint velocity and 2) supervised versus unsupervised sprint training on soccer-specific physical performance in junior soccer players. ... -
The Andersen Aerobic Fitness Test: reliability and validity in 10-year-old children
(Journal article; Peer reviewed, 2014-10-17)Background: High aerobic fitness is consistently associated with a favorable metabolic risk profile in children. Direct measurement of peak oxygen consumption (VO2peak) is often not feasible, thus indirect tests such as ... -
Training at maximal power in resisted sprinting: Optimal load determination methodology and pilot results in team sport athletes
(Journal article; Peer reviewed, 2018)Aims: In the current study we investigated the effects of resisted sprint training on sprinting performance and underlying mechanical parameters (force-velocity-power profile) based on two different training protocols: (i) ... -
Training-induced increase in Achilles tendon stiffness affects tendon strain pattern during running
(Peer reviewed; Journal article, 2019)Background: During the stance phase of running, the elasticity of the Achilles tendon enables the utilisation of elastic energy and allows beneficial contractile conditions for the triceps surae muscles. However, the effect ... -
Upper-Body Muscular Endurance Training Improves Performance Following 50 min of Double Poling in Well-Trained Cross-Country Skiers.
(Peer reviewed; Journal article, 2017)This study investigated the effect of muscular endurance training on O2-cost and performance in double poling (DP) on a rollerski treadmill. Twenty-two well-trained cross-country skiers (31 ± 4 years, 77 ± 9 kg, 181 ± 8 ...
