    • Contribution from cross-country skiing, start time and shooting components to the overall and isolated biathlon pursuit race performance 

      Luchsinger, Harri Simon; Kocbach, Jan; Ettema, Gerardus Johannes C; Sandbakk, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-14)
      <i>Purpose</i> - Biathlon is an Olympic sport combining 3–5 laps of cross-country skiing with rifle shooting, alternating between the prone and standing shooting positions between laps. The individual distance and the sprint are extensively examined whereas the pursuit, with start times based on the sprint results, is unexplored. Therefore, the current study aimed to investigate the contribution ...

    • Development of a Framework for the Investigation of Speed, Power and Kinematic Patterns in Para Cross-Country Sit-Skiing: A Case Study of an LW12 Athlete 

      Baumgart, Julia Kathrin; Haugnes, Pål; Bardal, Lars Morten; Østerås, Sindre; Kocbach, Jan; Sandbakk, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-31)
      <i>Objective</i>: To develop a framework for the investigation of speed, power, and kinematic patterns across varying terrain in cross-country (XC) sit-skiing, and to test this framework in a XC sit-skier of the LW12 class during high- (HIT) and low-intensity (LIT) endurance training.<p> <p><i>Methods</i>: One XC sit-skiing athlete of the LW12 class with a single above-the-knee amputation was ...

    • The dynamics of the anaerobic energy contribution during a simulated mass-start competition while roller-ski skating on a treadmill. 

      Noordhof, Dionne; Danielsson, Marius Lyng; Skovereng, Knut; Danielsen, Jørgen; Seeberg, Trine Margrethe; Haugnes, Pål; Kocbach, Jan; Ettema, Gertjan; Sandbakk, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-08)
      The purposes of this study were: 1) to investigate the anaerobic energy contribution during a simulated cross-country (XC) skiing mass-start competition while roller-ski skating on a treadmill; 2) to investigate the relationship between the recovery of the anaerobic energy reserves and performance; and 3) to compare the gross efficiency (GE) method and maximal accumulated oxygen deficit (MAOD) to ...

    • The influence of race tactics for performance in the heats of an international sprint cross-country skiing competition 

      Haugnes, Pål; Kocbach, Jan; Kjøsen Talsnes, Rune; Noordhof, Dionne; Ettema, Gertjan; Sandbakk, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-09)
      The purpose of this study was to examine the influence of race tactics for performance in the heats of an international sprint cross-country (XC) skiing competition in the classical style. Thirty elite male XC skiers (age: 24±3 years, sprint International Ski Federation [FIS] points: 61±27) performed a sprint time-trial (STT) followed by one to three ‘knock-out’ heats on a 1.7 km racecourse. An ...

    • Physiological and Biomechanical Determinants of Sprint Ability Following Variable Intensity Exercise When Roller Ski Skating 

      Seeberg, Trine Margrethe; Kocbach, Jan; Danielsen, Jørgen; Noordhof, Dionne; Skovereng, Knut; Hatling Haugnes, Pål; Tjønnås, Johannes; Sandbakk, Øyvind Bucher (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-25)
      The most common race format in cross-country (XC) skiing is the mass-start event, which is under-explored in the scientific literature. To explore factors important for XC skiing mass-starts, the main purpose of this study was to investigate physiological and biomechanical determinants of sprint ability following variable intensity exercise when roller ski skating. Thirteen elite male XC skiers ...

    • Physiological and Biomechanical Responses to Cross-Country Skiing in Varying Terrain: Low- vs. High-Intensity 

      Seeberg, Trine Margrethe; Kocbach, Jan; Danielsen, Jørgen; Noordhof, Dionne; Skovereng, Knut; Meyer, Frederic; Sandbakk, Øyvind Bucher (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-11)
      The purposes of our study were to investigate the physiological and biomechanical responses to low-intensity (LI) and high-intensity (HI) roller ski skating on varying terrain and compare these responses between training intensities. Nine elite male skiers performed treadmill roller skiing consisting of two 21 min sessions (7 × 3 min laps) at LI and HI with the same set inclines and intensity-dependent ...
