  • 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 ...

  • En casestudie av Ski- og Skredworkshopen i Sogndal - med fokus på menneskelige faktorer 

    Holstad, Elias Grimstad (Master thesis; Mastergradsoppgave, 2019-05-15)
    I Norge var det flere dødsfall som følge av snøskred sesongen 2018/19 enn det har vært på mange år. De fleste snøskredulykkene som involverer folk med kunnskap om snøskred er en følge av menneskelige faktorer. Selv om mange har kunnskapen som skal til for å holde seg trygge, fører menneskelige faktorer til at de ikke klarer å benytte denne kunnskapen for å unngå å havne i snøskredulykker. I denne ...

    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 ...
