      Individual training responses among endurance athletes are determined by a complex interplay between training load, recovery and genetic influence. The present study used a multidisciplinary approach to compare high- and low-responders following a 6-month training period in endurance athletes transferring to cross-country (XC) skiing. Twenty-three endurance-trained athletes (14 runners and 9 ...

      Valstad, Sverre; Heimburg, Erna von; Welde, Boye; van den Tillaar, Roland (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-18)
      This study compared the effects of long (4×4 min) and short intervals (4×8×20 s) of high-intensity interval exercise bouts (HIIT) on running performance, physiological and perceptual responses, and excess postexercise oxygen consumption (EPOC). Twelve healthy college students (8 men, 4 women; mean age=22±2 years) performed long (90–95% of peak heart rate) and short intervals (maximal intensity) of ...

      <p><i>Background</i>: The aim of this study was to compare the effect of different soccer-specific maximal actions (Continuous run, Sprint, Sprint with change of direction [Sprint COD], Jump and Shot) upon physiological (oxygen uptake and heart rate) and perceptual (rating of perceived exertion [RPE]) responses and accelerometer load.</p> <p><i>Materials and methods</i>: Ten moderately to ...
    • The influence of improvisation activities on speaking confidence of EFL student teachers 

      Zondag, Anke; Larsen, Annelise Brox; Guldal, Tale Margrethe; van den Tillaar, Roland (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-17)
      The purpose of the present study was to explore the application of improvisation activities in English teacher education, specifically to investigate their influence on the student teachers’ confidence when speaking English spontaneously. The improvisation activities consisted of storytelling, conversations and status expressions. Data were drawn from both pre- and post-questionnaires and retrospective ...
