Dietary Nitrate and Nitric Oxide Metabolism Mouth, Circulation, Skeletal Muscle, and Exercise Performance
(Peer reviewed; Journal article, 2020)Nitric oxide (NO) is a gaseous signaling molecule that plays an important role in myriad physiological processes including the regulation of vascular tone, neurotransmission, mitochondrial respiration and skeletal muscle ... -
Dieting to win or to be thin? a study of dieting and disordered eating among adolescent elite athletes and non-athlete controls
(Journal article; Peer reviewed, 2010-01)Objective: To examine the prevalence of dieting, reasons for dieting and prevalence of disordered eating among adolescent elite athletes and age-matched controls, and to examine the differences between athletes competing ... -
Differences between elite and sub-elite swimmers in a 100 m breaststroke: A new race analysis approach with time-series velocity data
(Peer reviewed; Journal article, 2021)The purpose of the present study was to investigate differences in a 100 m breaststroke time-trial between elite and sub-elite swimmers. Elite and sub-elite male swimmers (seven each; 772.1 ± 35.2 and 610.6 ± 24.7 FINA ... -
Differences in fat loss in response to physical activity among severely obese men and women
(Journal article; Peer reviewed, 2014-02-04)Background: Direct measurement of physical activity may be critical to revealing its relationship with the change in fat mass over time. The aim of this study was to determine the relationship between accelerometer-determined ... -
Differences in limb coordination in polyrhythmic production among water polo players, artistic swimmers and drummers
(Peer reviewed; Journal article, 2020)This study compares polyrhythmic production ability between water polo players (WPs), artistic swimmers (ASs) and drummers (Ds), to assess how their differing experiences in coordinating complex inter-limb activity with ... -

(Peer reviewed; Journal article, 2020)This study compares polyrhythmic production ability between water polo players (WPs), artistic swimmers (ASs) and drummers (Ds), to assess how their differing experiences in coordinating complex inter-limb activity with ... -
Differences in lung function, bronchial hyperresponsiveness and respiratory health between elite athletes competing in different sports
(Peer reviewed; Journal article, 2022)The aim of this study was to examine lung function, bronchial hyperresponsiveness (BHR) and exercise-induced respiratory symptoms in elite athletes performing different sports. Norwegian national-team athletes (30 swimmers, ... -
Differences in race characteristics between world-class individual-medley and stroke-specialist swimmers
(Peer reviewed; Journal article, 2022)The purpose of the present study was to investigate differences between world-class individual medley (IM) swimmers and stroke-specialists using race analyses. A total of eighty 200 m races (8 finalists × 2 sexes × 5 events) ... -
Differences in the rotational effect of buoyancy and trunk kinematics between front crawl and backstroke swimming
(Peer reviewed; Journal article, 2021)The purpose of the present study is to investigate differences between front crawl and backstroke swimming in hydrodynamic (produced by swimmers) and buoyant torque around the transverse axis. Ten swimmers performed 50 m ... -
Different factors associate with body image in adolescence than in emerging adulthood: A gender comparison in a follow-up study
(Journal article; Peer reviewed, 2017-10-31)All individuals have a certain perception of their own body, called body image. The view on body image is two dimensional: attitudinal and perceptual (Soponaru, Bojian, & Lorga, 2016). The attitudinal dimension is a ... -
Different resistance exercise loading paradigms similarly affect skeletal muscle gene expression patterns of myostatin-related targets and mTORC1 signaling markers
(Peer reviewed; Journal article, 2023)Although transcriptome profiling has been used in several resistance training studies, the associated analytical approaches seldom provide in-depth information on individual genes linked to skeletal muscle hypertrophy. ... -
