The influence of a fast start versus a conservative start pacing strategy on sprint roller skiing performance in highly trained female junior skiers
(Peer reviewed; Journal article, 2023)Purpose: Pacing profiles differ substantially in endurance sports with short competition duration (2–4 min). Herein, we investigated the effect of a fast start (FS) versus a conservative start (CS) pacing strategy on sprint ... -
Justifying anti-doping: The fair opportunity principle and the biology of performance enhancement
(Journal article; Peer reviewed, 2011-10-28)Doping is a complex moral and scientific dilemma and its prevention has led to a costly but less than perfect control system implemented worldwide by the World Anti-doping Agency (WADA). For a substance or method to be ... -
Kinematical analysis of the V2 ski skating technique: A longitudinal study
(Journal article; Peer reviewed, 2017)To characterise timing of movements and evaluate performance effects of technique alterations in V2 ski skating, 13 elite male cross-country skiers (age, 23 ± 2 years; stature, 182 ± 6 cm; body mass, 76 ± 8 kg; V2 V̇O2max, ... -
Mindfulness and shooting performance in biathlon. A prospective study
(Peer reviewed; Journal article, 2020)The aim of the study was to examine the temporal relationship between facets of sport-specific dispositional mindfulness (i e., Awareness, Refocusing, Nonjudgemental attitude) and shooting performance in actual competitions, ... -
Muscle activation in world champions, world-class and national breaststroke swimmers
(Journal article; Peer reviewed, 2016-08)Purpose: Investigating the muscle activation patterns and coactivation with the support of kinematics in some of the world’s best breaststrokers and identify performance discriminates related to national elites at maximal ... -
New opportunities to advance the field of sports nutrition
(Peer reviewed; Journal article, 2022)Sports nutrition is a relatively new discipline; with ~100 published papers/year in the 1990s to ~3,500+ papers/year today. Historically, sports nutrition research was primarily initiated by university-based exercise ... -
Prevalence and burden of health problems in competitive adolescent distance runners: A 6-month prospective cohort study
(Peer reviewed; Journal article, 2021)To describe all health problems (injuries and illnesses) in relation to type, location, incidence, prevalence, time loss, severity, and burden, in competitive adolescent distance runners in England. Prospective observational ... -
Progress update and challenges on VO2max testing and interpretation
(Peer reviewed; Journal article, 2020)The maximal oxygen uptake (VO2max) is the primary determinant of endurance performance in heterogeneous populations and has predictive value for clinical outcomes and all-cause mortality. Accurate and precise measurement ... -
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 ... -
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 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 ... -
Should we individualize training based on force-velocity profiling to improve physical performance in athletes?
(Peer reviewed; Journal article, 2021)The present study aimed to examine the effectiveness of an individualized training program based on force-velocity (FV) profiling on jumping, sprinting, strength, and power in athletes. Forty national level team sport ... -
Social status and sport: A study of young Norwegians
(Peer reviewed; Journal article, 2023)In this article, we study social status associated with sport. First, we examine the extent to which sport gives social status to Norwegian youths and athletes, how sport does so compared to other status markers and how ... -
Supplement with whey protein hydrolysate in contrast to carbohydrate supports mitochondrial adaptations in trained runners
(Peer reviewed; Journal article, 2020)Background: Protein supplementation has been suggested to augment endurance training adaptations by increasing mixed muscle and myofibrillar protein synthesis and lean body mass. However, a potential beneficial effect on ... -
