The effect of a school-based cluster randomized physical activity intervention study on symptoms of mental health problems amongst 14- year-old students in Akershus county, Norway
(Master thesis, 2020)Introduction: The prevalence of mental health problems has shown to increase amongst adolescents. Common interventions are often stigmatized, limiting the likelihood of adolescents seeking help for mental health related ... -
Longitudinal differences in participation across physical activity contexts between adolescents with and without disability: A self-determination theory perspective
(Master thesis, 2020)Introduction: Participation in physical activity (PA) is considered to have a profound influence on the development, health, and well being of all children and adolescents. Nevertheless, individuals with disabilities seem ... -
Active seniors in the outdoors: Experiences, health and wellbeing: A qualitative study of senior participants in an organized walking group in a small community in Norway
(Master thesis, 2020)Background: We are now living longer, and as these changes evolve, there is a need to consider environments that promote health and wellbeing among older adults. Nature has been an object of many studies, considering its ... -
Is there an association between total physical activity level and VO2max among fitness club members?: A prospective one-year follow-up study
(Master thesis, 2020)BACKGROUND: Since Cardiorespiratory fitness (CRF) is an important predictor for allcause mortality, it is vital to know if meeting the global physical activity (PA) recommendations of 150 minutes of moderate-to-vigorous ... -
Comparative analysis of power, work and muscle activation during weight-stack and iso-inertial flywheel resistance exercise in young adults with cerebral palsy
(Peer reviewed; Journal article, 2020)Introduction: The development of efficient resistance exercise protocols to counteract muscle dysfunction in cerebral palsy is warranted. Whether individuals with cerebral palsy are able to perform iso-inertial resistance ... -
Accelerometer-measured physical activity and sedentary time in a cohort of US adults followed for up to 13 years: The influence of removing early follow-up on associations with mortality
(Peer reviewed; Journal article, 2020)Background: Observational studies linking physical activity with mortality are susceptible to reverse causation bias from undiagnosed and prevalent diseases. Researchers often attempt to deal with reverse causation bias ... -
Alpine Ski Motion Characteristics in Slalom
(Peer reviewed; Journal article, 2020)Important insight into ski function, and ultimately skier technique and tactics, can be gained by studying how measured ski trajectories compare to predictions based on theoretical models of ski-snow interaction mechanics. ... -
Do declines in occupational physical activity contribute to population gains in body mass index? Tromsø Study 1974–2016
(Peer reviewed; Journal article, 2020)Objective: To examine whether occupational physical activity changes predict future body mass index (BMI) changes. Methods: This longitudinal cohort study included adult participants attending ≥3 consecutive Tromsø Study ... -
The effect of experience in movement coordination with music on polyrhythmic production: Comparison between artistic swimmers and water polo players during eggbeater kick performance
(Peer reviewed; Journal article, 2020)The aim of this study was to compare artistic swimmers (ASs) and water polo players (WPs) in their polyrhythmic production ability and entrainment between arm and leg motion frequency. Nine ASs and nine WPs participated ... -
Adaptations to strength training differ between endurance-trained and untrained women
(Peer reviewed; Journal article, 2020)Purpose: The purpose of this study was to investigate if endurance athletes, sustaining their normal endurance training, experience attenuated adaptations to strength training compared to untrained individuals. Methods: ... -
Association between physical activity and cognition in Mexican and Korean older adults
(Peer reviewed; Journal article, 2020)Introduction: As the world's population ages, the prevalence of cognitive impairment associated with age in- creases. This increase is particularly pronounced in Asia and South-America. The objective of this study was to ... -
Pole Length’s Influence on Performance During Classic-Style Snow Skiing in Well-Trained Cross-Country Skiers
(Peer reviewed; Journal article, 2020)Purpose: To investigate how self-selected pole length (PL) of ∼84% (PL84%) compared with ∼90% (PL90%) of body height influenced performance during a 700-m time trial with undulating terrain on snow. Methods: Twenty-one ... -
Physical activity attenuates metabolic risk of adolescents with overweight or obesity: The ICAD multi-country study
(Peer reviewed; Journal article, 2020)Background: Although the benefits of physical activity (PA) at an early age are well established, there is no robust evidence of the role of PA as well as its intensities in attenuating the association between weight status ... -
On the application of entropic half-life and statistical persistence decay for quantification of time dependency in human gait
(Peer reviewed; Journal article, 2020)Entropic half-life (ENT½) and statistical persistence decay (SPD) was recently introduced as measures of time dependency in stride time intervals during walking. The present study investigated the effect of data length on ... -
Contribution of oxygen extraction fraction to maximal oxygen uptake in healthy young men
(Peer reviewed; Journal article, 2020)We analysed the importance of systemic and peripheral arteriovenous O2 difference (a-vO2 difference and a-vfO2 difference, respectively) and O2 extraction fraction for maximal oxygen uptake (VO2max). Fick law of diffusion ... -
Variations in accelerometry measured physical activity and sedentary time across Europe: Harmonized analyses of 47,497 children and adolescents
(Peer reviewed; Journal article, 2020)Background: Levels of physical activity and variation in physical activity and sedentary time by place and person in European children and adolescents are largely unknown. The objective of the study was to assess the ... -
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 ... -
