• The influence of age on the match-to-match variability of physical performance in women’s elite football 

      Winther, Andreas Kjæreng; Pedersen, Sigurd; Johansen, Dag; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-15)
      Introduction: The fluctuation of external match load throughout a season is influenced by several contextual factors. While some, have been deeply analysed in men’s football literature, information is lacking on how other contextual elements, such as player’s age or experience, may affect the match-to-match variability of locomotor activities. In fact, aging has been described as a multifactorial ...
    • Maximal Strength, Sprint, and Jump Performance in High-Level Female Football Players Are Maintained With a Customized Training Program During the COVID-19 Lockdown 

      Pedersen, Sigurd; Johansen, Dag; Pettersen, Svein Arne; Sagelv, Edvard Hamnvik; Welde, Boye; Winther, Andreas Kjæreng; Casolo, Andrea; Randers, Morten B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-26)
      Introduction: The COVID-19 outbreak with partial lockdown has inevitably led to an alteration in training routines for football players worldwide. Thus, coaches had to face with the novel challenge of minimizing the potential decline in fitness during this period of training disruption.<p> <p>Methods: In this observational pre- to posttest study involving Norwegian female football players (18.8 ...
    • The pacing strategy and technique of male cross-country skiers With different levels of performance during a 15-km classical race 

      Welde, Boye; Stöggl, Thomas; Mathisen, Gunnar; Supej, Matej; Zoppirolli, Chiara; Winther, Andreas Kjæreng; Pellegrini, Barbara; Holmberg, Hans-Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-08)
      In this study the pacing strategy, cycle characteristics and choice of technique of elite male cross-country (XC) skiers during a three-lap, 15-km classical race with interval start were measured. During the Norwegian Championships in 2016, fast (n = 18, age: 26±4 yr; height: 182±4 cm; body mass: 78±3 kg (means±SD)) and slow skiers (n = 18, age: 22±2 yr; height: 183±5 cm; body mass: 78±6 kg) were ...
    • Position specific physical performance and running intensity fluctuations in elite women's football 

      Winther, Andreas Kjæreng; Matias Do Vale Baptista, Ivan Andre; Pedersen, Sigurd; Thomsen, Morten Brendsgaard Randers; Krustrup, Peter; Johansen, Dag; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-26)
      The purpose of the present study was to investigate the physical performance of elite female football players during match play along with transient alterations in running performance following 1- and 5-min univariate peak periods. 54 elite female players from four top-level Norwegian teams were monitored for one season (n = 393 match observations), and physical performance data collected using ...

    • Should we be recommending altitude training to swimmers? 

      Winther, Andreas Kjæreng (Master thesis; Mastergradsoppgave, 2018-05-15)
      Many swimmers continue to use altitude training as part of their preparation despite questions of its efficacy. This belief seems to be strongly tied to the notion that an increase in hemoglobin mass will transfer over to increased sea-level performance. The purpose of the presents study was to examine whether altitude training lead to greater increases in competitive performance compared to sea-level ...
    • Ski Skating Race Technique—Effect of Long Distance Cross-Country Ski Racing on Choice of Skating Technique in Moderate Uphill Terrain 

      Ardigò, Luca Paolo; Stöggl, Thomas Leonhard; Thomassen, Tor Oskar; Winther, Andreas Kjæreng; Sagelv, Edvard Hamnvik; Pedersen, Sigurd; Hammer, Tord; Heitmann, Kim Arne; Olsen, Odd-Egil; Welde, Boye (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-14)
      The aim of this study was to investigate the effect of prolonged ski racing using skating style on technique choice in a transition section among female and male high-level skiers. Fifty three national-to-elite level skiers (20 females: 26.7 ± 4.8 years, 167.0 ± 6.5 m, 61.0 ± 5.1 kg, and 75.5 ± 68.8 FIS points; 33 males: 25.2 ± 3.5 years, 179.0 ± 5.2 cm, 73.1 ± 5.7 kg, and 73.7 ± 63.2 FIS points) ...
    • The variability of physical match demands in elite women's football 

      Matias Do Vale Baptista, Ivan Andre; Winther, Andreas Kjæreng; Johansen, Dag; Bredsgaard Randers Thomsen, Morten; Pedersen, Sigurd; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-21)
      Peak locomotor demands are considered as key metrics for conditioning drills prescription and training monitoring. However, research in female football has focused on absolute values when reporting match demands, leading to sparse information being provided regarding the degrees of variability of such metrics. Thus, the aims of this study were to investigate the sources of variability of match ...
