Blood volume expansion does not explain the increase in peak oxygen uptake induced by 10 weeks of endurance training
(Peer reviewed; Journal article, 2020)Purpose: The endurance training (ET)-induced increases in peak oxygen uptake (V˙O2peak) and cardiac output (Q˙peak) during upright cycling are reversed to pre-ET levels after removing the training-induced increase in blood ... -
Body composition and mortality from middle to old age: a prospective cohort study from the UK Biobank
(Peer reviewed; Journal article, 2023)Background: How the association between adiposity and the risk of death changes with age, and which is the optimal level of adiposity to reduce mortality in older ages, is still not completely understood. We aimed to ... -
Body figure idealization and body appearance pressure in fitness instructors
(Peer reviewed; Journal article, 2020)Purpose: The fitness centers are settings for health promotion, yet may serve as a stage for counterproductive figure idealization. Such idealization may take the form of a drive toward the thin, the muscular, or lean body ... -
Body roll amplitude and timing in backstroke swimming and their differences from front crawl at the same swimming intensities
(Peer reviewed; Journal article, 2021)The current study investigated body roll amplitude and timing of its peak in backstroke and compared them with front crawl swimming. Nineteen anatomical landmarks were digitised using 80 swimming trial videos (ten ... -
Bone health in elite Norwegian endurance cyclists and runners: a cross-sectional study
(Journal article; Peer reviewed, 2018)Background: Athletes who compete in non-weight-bearing activities such as swimming and cycling are at risk of developing low bone mineral density (BMD). Athletes in long-distance running are at risk of low BMD. Objective: ... -
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, ... -
Branched-chain amino acid metabolism, insulin sensitivity and liver fat response to exercise training in sedentary dysglycaemic and normoglycaemic men
(Peer reviewed; Journal article, 2020)Aims/hypothesis: Obesity and insulin resistance may be associated with elevated plasma concentration of branched-chain amino acids (BCAAs) and impaired BCAA metabolism. However, it is unknown whether the insulin-sensitising ... -
Branched-chain amino acids supplementation does not accelerate recovery after a change of direction sprinting exercise protocol
(Peer reviewed; Journal article, 2022)BCAAs supplementation has been widely used for post-exercise recovery. However, no evidence is currently available to answer the question of whether BCAAs supplementation can attenuate muscle damage and ameliorate recovery ... -
Bubbles & Squat – did Dionysus just sneak into the fitness centre?
(Journal article; Peer reviewed, 2018)A Danish fitness chain recently introduced a new concept called Bubbles & Squat. Here, fitness training is combined with free champagne and music. In this paper, we examine this new way of bringing parties, alcohol and ... -
Caffeine Increases Strength and Power Performance in Resistance-trained Females During Early Follicular Phase
(Peer reviewed; Journal article, 2020)The effects of 4 mg·kg−1caffeine ingestion on strength and power were investigated for the first time, in resistance‐trained females during the early follicular phase utilizing a randomized, double‐blind, placebo‐controlled, ... -
CAM-type femoroacetabular impingement in male elite junior cross-country skiers and non-athlete controls: A cross-sectional MRI study
(Peer reviewed; Journal article, 2019)OBJECTIVES: Cross-country (CC) skiing consists of two main techniques: classic and skating. Hip motion during the skating technique is similar to that in ice skating and is considered a risk factor for femoroacetabular ... -
Can maximal voluntary pelvic floor muscle contraction reduce vaginal resting pressure and resting EMG activity?
(Journal article; Peer reviewed, 2018)Introduction and hypothesis: The purpose of the present study was to assess whether attempts at a maximal voluntary pelvic floor muscle (PFM) contraction can reduce vaginal resting pressure (VRP) and surface EMG activity ... -
Can you breathe yourself to a better pelvic floor?: A systematic review
(Peer reviewed; Journal article, 2023)Introduction: Some authors suggest that breathing exercises should be recommended instead of or in combination with pelvic floor muscle training (PFMT) to prevent and treat urinary incontinence (UI) and pelvic organ prolapse ... -
Can β2-agonists have an ergogenic effect on strength, sprint or power performance? Systematic review and meta-analysis of RCTs
(Peer reviewed; Journal article, 2020)Objectives: We aimed to examine the effect of β2-agonists on anaerobic performance in healthy non-asthmatic subjects. Design: Systematic review and meta-analysis. Eligibility criteria: We searched four databases (PubMed, ... -
Cardiometabolic associations between physical activity, adiposity, and lipoprotein subclasses in prepubertal Norwegian children
(Peer reviewed; Journal article, 2021)Lipoprotein subclasses possess crucial cardiometabolic information. Due to strong multicollinearity among variables, little is known about the strength of influence of physical activity (PA) and adiposity upon this ... -
Cardiorespiratory fitness and physical activity following lung transplantation: A national cohort study
(Peer reviewed; Journal article, 2020)Background: Low cardiorespiratory fitness and inactivity are common after lung transplantation (LTx). The causes of exercise intolerance are incompletely understood. Objectives: The aim of this study was to objectively ... -
Cardiorespiratory fitness assessment using risk-stratified exercise testing and dose–response relationships with disease outcomes
(Peer reviewed; Journal article, 2021)Cardiorespiratory fitness (CRF) is associated with mortality and cardiovascular disease, but assessing CRF in the population is challenging. Here we develop and validate a novel framework to estimate CRF (as maximal oxygen ... -
Cardiorespiratory fitness on a treadmill in an adult cystic fibrosis population
(Peer reviewed; Journal article, 2020)Objectives: (1) To describe the cardiorespiratory fitness (CRF) in an adult cystic fibrosis population related to sex and age, (2) to evaluate the cause of low CRF and (3) to study the association between peak oxygen uptake ... -
