Betydningen av sosial klasse for elevers motivasjon for og karakterer i kroppsøving: En kvantitativ studie av 854 ungdommer i Norge
(Master thesis, 2013)Sosial klasse som begrep har gjennom historien utviklet seg til å bli mer komplekst og uklart enn det Karl Marx (1818-1883) og etterhvert Max Weber (1864-1920) først antok. Denne studien har sett på sosial klasse og dens ... -
Betydningen av utøver-trenerforholdet i gode og dårlige sesonger for elitelangrennsløperes motivasjon: et selvbestemmelsesteoretisk perspektiv
(Master thesis, 2010)For å komme på et høyt prestasjonsnivå i eliteidrett er det nødvendig med hardt og målrettet treningsarbeid over flere år (Rusko, 2003). I eliteutøveres kontekst finnes det i tillegg mange ytre faktorer utøverne må ... -
Beyond life-skills: Talented athletes, existential learning and (un)learning the life of an athlete
(Peer reviewed; Journal article, 2022)Following developments in educational discourse more broadly, learning discourses in youth sport have been shaped by outcome-based and instrumental goals of developing useful life-skills for ‘successful’ lives. There is, ... -
Beyond planning: the implementation of a worksite health promotional scheme
(Journal article; Peer reviewed, 2012-05)The aim of this article is to provide insight into how the presence of diverging organizational logics influences the outcome of worksite health promotion projects. The study is based on a one-year qualitative single-case ... -
Bicycling in the right direction? : Two systematic literature reviews with meta-analyses of cycling and cardiovascular disease, followed by national correlates of commuter cycling and the presentation of a novel bike tra c index to describe trends in cycling over the years.
(Doctoral thesis, 2021)Background: The world population needs to be more physically active. Cardiovascular disease (CVD) is one of the leading causes of death and can be prevented by physical activity. Cycling as transportation may be a means ... -
Bicycling to school improves the cardiometabolic risk factor profile: a randomised controlled trial
(Journal article; Peer reviewed, 2012-10-31)Objectives To investigate whether bicycling to school improves cardiometabolic risk factor profile and cardiorespiratory fitness among children. Design Prospective, blinded, randomised controlled trial. Setting Single ... -
The bidirectional associations between leisure time physical activity change and body mass index gain. The Tromsø Study 1974–2016
(Peer reviewed; Journal article, 2021)Objectives To examine whether leisure time physical activity changes predict subsequent body mass index (BMI) changes, and conversely, whether BMI changes predict subsequent leisure time physical activity changes. Methods: ... -
Biological treatment of the knee with platelet-rich plasma or bone marrow aspirate concentrates
(Journal article; Peer reviewed, 2017-08-23)Knee pathologies including focal cartilage injuries, osteoarthritis (OA), and ligament injuries are common. The poor regeneration and healing potential of cartilage has led to the search for other treatment modalities with ... -
Biomechanical analysis of defensive cutting actions during game situations: six cases in collegiate soccer competitions
(Journal article; Peer reviewed, 2015-07-10)The strengths of interpersonal dyads formed by the attacker and defender in one-on-one situations are crucial for performance in team ball sports such as soccer. The purpose of this study was to analyze the kinematics of ... -
