    • The effect of a school-based intervention on physical activity, cardiorespiratory fitness and muscle strength: The School in Motion cluster randomized trial 

      Kolle, Elin; Solberg, Runar Barstad; Säfvenbom, Reidar; Dyrstad, Sindre Mikal; Berntsen, Sveinung; Resaland, Geir Kåre; Ekelund, Ulf; Anderssen, Sigmund Alfred; Steene-Johannessen, Jostein; Grydeland, May (Peer reviewed; Journal article, 2020)
      Background: Physical activity (PA) declines throughout adolescence, therefore PA promotion during this period is important. We analyzed the effect of two school-based PA interventions on daily PA levels, cardiorespiratory ...

      Objectives: To determine if subpopulations of students benefit equally from school-based physical activity interventions in terms of cardiorespiratory fitness and physical activity. To examine if physical activity intensity ...
    • Waist circumference thresholds and cardiorespiratory fitness 

      Dyrstad, Sindre Mikal; Edvardsen, Elisabeth; Hansen, Bjørge Herman; Anderssen, Sigmund Alfred (Peer reviewed; Journal article, 2017)
      Purpose: This study's purpose was to examine whether established risk categories of waist circumference (WC)—normal, high risk, and very high health risk—reflected significant differences in cardiorespiratory fitness (CRF) ...
