    • Comparison of Long and Short High-Intensity Interval Exercise Bouts on Running Performance, Physiological and Perceptual Responses 

      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 ...

    • Influence of different soccer-specific maximal actions on physiological, perceptual and accelerometer measurement loads 

      Dalen, Terje; Øverås, Ørjan; van den Tillaar, Roland; Welde, Boye; von Heimburg, Erna Dianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-13)
      <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 ...
