  • Hva gjøres for å fremme fysisk aktivitet i barnehager? En komparativ studie av førskolelæreres virksomhet i 1981 og 2009 

    Stokke, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-01-01)
    Artikkelen viser empiri fra to like spørreskjemaundersøkelser, fra 1981 og 2009, der førskolelærerne selv skriver hva de gjør av virksomhet for å fremme fysisk aktivitet. Sammenlignes resultatene, viser det at det gjøres mer i dag for å fremme fysisk aktivitet enn i 1981. ”Å fornye det fysiske miljøet” var det eneste tiltaket det var gjort mindre av. En forklaring kan være mer naturmiljø i barnehagene ...
  • Et blikk på barns vilkår for fysisk aktivitet inne i barnehager : en komparativ studie, 1981 og 2009 

    Stokke, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-01-01)
    Det fysiske miljøet har betydning for barns lek og læring og det er viktig for kvaliteten i barnehagers virksomhet. Hvilke innemiljø tilbys barna, hvor mye tid får barna til lek inne og hvilke restriksjoner finnes knyttet til fysisk aktiv lek? Artikkelen vil især fokusere på kroppslig lek og endringer over tid. Derfor vil resultatene fra en landsrepresentativ kvantitativ spørreundersøkelse i norske ...
  • Et blikk på barns vikår for fysisk aktivitet i barnehager. En komparativ studie, 1981 og 2009 

    Stokke, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-01-01)
    Forskning viser at det fysiske miljøet er en nøkkeldeterminant for barns fysiske aktivitetsnivå. I Rammeplan for barnehagens innhold og oppgaver står det: Barnehagen skal ha areal og utstyr nok, tilby gode oppvekstmiljø som er både trygge og utfordrende og som skal fremme læring og mestring (KD 2006). I denne artikkelen presenteres resultater fra en landsrepresentativ kvantitativ spørreundersøkelse ...
  • Web-based exercise versus supervised exercise for decreasing visceral adipose tissue in older adults with central obesity: A randomized controlled trial 

    Ballin, Marcel; Hult, Andreas; Björk, Sabine; Lundberg, Emmy; Nordström, Peter; Nordström, Anna Hava (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-12)
    <i>Background</i> - Visceral adipose tissue (VAT) is a strong risk factor for cardiovascular disease and increases with age. While supervised exercise (SE) may be an effective approach, web-based exercise (WE) have other advantages such as being more readily accessible. Therefore, we evaluated the effects of WE on VAT, body composition and cardiometabolic risk markers in centrally obese older adults ...

  • Resource rent in aquaculture 

    Flaaten, Ola; Pham, Thi Thanh Thuy (Chapter; Bokkapittel, 2019)
    Resource rent in aquaculture (RRA) is any payment to a farm and site owner, on land or sea, in excess of the costs needed to bring that farm into production. For analytic and policy purposes it may be useful to distinguish among different types of RRA. Three types will be discussed: rent associated with the classical economists Ricardo (1821) and Faustmann (1849), as well as oligopoly rent from ...
  • The Potential Usefulness of Virtual Reality Systems for Athletes: A Short SWOT Analysis 

    Düking, Peter; Holmberg, Hans-Christer; Sperlich, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-05)
    Virtual reality (VR) systems (Neumann et al., 2017), which are currently receiving considerable attention from athletes, create a two- or three-dimensional environment in the form of emulated pictures and/or video-recordings where in addition to being mentally present, the athlete even often feels like he/she is there physically as well. As she/he interacts with and/or reacts to this environment, ...

  • The influence of physiobiomechanical parameters, technical aspects of shooting, and psychophysiological factors on biathlon performance: A review 

    Laaksonen, Marko S; Finkenzeller, Thomas; Holmberg, Hans-Christer; Sattlecker, Gerold (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-08)
    The biathlon, an Olympic sporting discipline that combines cross-country skiing with rifle marksmanship, entails considerable physiological demands, as well as fine motor control while shooting after intense exercise and under mental pressure. Although much of our knowledge about cross-country skiing is probably also applicable to the biathlon, carrying the rifle and shooting under stress make ...
  • Pacing and predictors of performance during cross-country skiing races: A systematic review 

    Stöggl, Thomas; Pellegrini, Barbara; Holmberg, Hans-Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-15)
    <i>Background</i>: Cross-country skiing (XCS) racing, a popular international winter sport, is complex and challenging from physical, technical, and tactical perspectives. Despite the vast amount of research focusing on this sport, no review has yet addressed the pacing strategies of elite XCS racers or the factors that influence their performance. The aim was to review the scientific literature ...
  • Macro-kinematic differences between Sprint and Distance cross-country skiing competitions using the classical technique 

    Marsland, Finn; Anson, Judith; Waddington, Gordon; Holmberg, Hans-Christer; Chapman, Dale W (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-17)
    We compare the macro-kinematics of six elite female cross-country skiers competing in 1.1-km Sprint and 10.5-km Distance classical technique events on consecutive days under similar weather and track conditions. The relative use of double pole (DP), kick-double pole (KDP), diagonal stride (DS), tucking (Tuck) and turning (Turn) subtechniques, plus each technique’s respective velocities, cycle ...
  • Following a long-distance classical race the whole-body kinematics of double poling by elite cross-country skiers are altered 

    Zoppirolli, Chiara; Bortolan, Lorenzo; Stella, Federico; Boccia, Gennaro; Holmberg, Hans-Christer; Schena, Federico; Pellegrini, Barbara (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-25)
    Introduction: <br>Although short-term (approximately 10-min) fatiguing DP has been reported not to alter the joint kinematics or displacement of the centre of mass (COM) of high-level skiers, we hypothesize that prolonged DP does change these kinematics, since muscular strength is impaired following endurance events lasting longer than 2 h. <br>Methods:<br> During the 58-km Marcialonga race ...
  • Integrated framework of load monitoring by a combination of smartphone applications, wearables and point-of-care testing provides feedback that allows individual responsive adjustments to activities of daily living 

    Düking, Peter; Achtzehn, Silvia; Holmberg, Hans-Christer; Sperlich, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-19)
    Athletes schedule their training and recovery in periods, often utilizing a pre-defined strategy. To avoid underperformance and/or compromised health, the external load during training should take into account the individual’s physiological and perceptual responses. No single variable provides an adequate basis for planning, but continuous monitoring of a combination of several indicators of ...
  • The muscle fiber profiles, mitochondrial content, and enzyme activities of the exceptionally well-trained arm and leg muscles of elite cross-country skiers 

    Ørtenblad, Niels; Nielsen, Joachim; Boushel, Robert; Söderlund, Karin; Saltin, Bengt; Holmberg, Hans-Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-02)
    As one of the most physically demanding sports in the Olympic Games, crosscountry skiing poses considerable challenges with respect to both force generation and endurance during the combined upper- and lower-body effort of varying intensity and duration. The isoforms of myosin in skeletal muscle have long been considered not only to define the contractile properties, but also to determine metabolic ...
