      Lagestad, Pål Arild; Welde, Boye; Rånes, Vebjørn; Myhre, Hege (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-02)
      Little is known about absenteeism in high school physical education (PE) in relation to study programme and gender. This study investigated the impact of gender and study programme on absentee rates in PE by analyzing data, using non-parametric statistical analyses, from the absentee registers for all 6928 students in Nordland Country. The results showed that the absentee rates in PE differed among ...

    • Aerobic Games and Playful Exercises in 9-Year-Old Boys: Intensity and Fitness Effects 

      Mathisen, Gunnar; Jensen, Rein Magnus; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Previous research on exercise for pre-adolescents with the purpose of improving aerobic fitness levels has yielded contradictory results. Sufficient training intensity, frequency and duration are the crucial factors in achieving this goal; the question, however, is whether it is possible to reach sufficient intensity levels using aerobic games and playful exercises. Variety and fun are the important ...

    • Anthropometric factors related to sprint and agility performance in young male soccer players 

      Mathisen, Gunnar; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-05)
      Objective: To investigate the relationship between anthropometrics and sprint and agility performance and describe the development of sprint (acceleration) and agility performance in 10- to 16-year-old male soccer players. <p>Methods: One hundred and thirty-two participants were divided into three age groups, 10–12 years (mean 10.8±0.50), 13–14 years (mean 13.9±0.50), and 15–16 years (mean 15.5±0.24), ...
    • Barn og fysisk aktivitet i barnehagen: Hvordan kan aktivitetsnivået dokumenteres? 

      Stokke, Anne; Weydahl, Andi; Calogiuri, Giovanna (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Vi målte det fysiske aktivitetsnivået til 42 barn i løpet av en vanlig dag i barnehagen ved hjelp av ulike instrumenter. Denne studien vil gi kunnskap om barns fysiske aktivitet i barnehagen, og om barnas aktivitetsnivå kan bli tilstrekkelig evaluert av lærerne eller om det er behov for tekniske målinger. Videre har vi sammenlignet de ulike instrumentene brukt i observasjonen. De ansatte i barnehagen ...
    • Chronotype and response to training during the polar night: a pilot study 

      Vitale, Jacopo Antonino; Bjørkesett, Eva; Campana, Andrea; Panizza, Giacomo; Weydahl, Andi (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)
      Background:<br> An individual’s chronotype influences his or her physiological rhythms. Some studies have looked at the effect of time of day on the responses to exercise, but studies on the effect of long-term training are lacking. <br>Objective:<br> To report the effects of an 8-week training period during the polar night in non- athletes of different chronotypes living at 70°N. <br>Design:<br> ...
    • Chronotype, Physical Activity, and Sport Performance: A Systematic Review 

      Vitale, Jacopo Antonino; Weydahl, Andi (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-11)
      Background:<br> Many variables related to sport have been shown to have circadian rhythms. Chronotype is the expression of circadian rhythmicity in an individual, and three categories of chronotype are defined: morning types (M-types), evening types (E-types), and neither types (N-types). M-types show earlier peaks of several psychophysiological variables during the day than E-types. The effect ...
    • A comparison between two different conditions of breaking up sedentary behaviour on glucose metabolism 

      Sagelv, Edvard Hamnvik; Ekelund, Ulf; Stensrud, Trine (Conference object; Konferansebidrag, 2016-05-30)
      Conclusion: There is no effect of either breaking up sedentary behaviour each hour or performing 30 minutes of vigorous physical activity in one bout compared with prolonged sitting for six hours on glucose metabolism.
    • Comparison of non-invasive individual monitoring of the training and health of athletes with commercially available wearable technologies 

      Düking, Peter; Hotho, Andreas; Holmberg, Hans-Christer; Sperlich, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-09)
      Athletes adapt their training daily to optimize performance, as well as avoid fatigue, overtraining and other undesirable effects on their health. To optimize training load, each athlete must take his/her own personal objective and subjective characteristics into consideration and an increasing number of wearable technologies (wearables) provide convenient monitoring of various parameters. ...
    • Den norske idrettsmodellen - i utakt med tiden? 

      Rafoss, Kolbjørn; Tangen, Jan Ove (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      I artikkelen drøftes spørsmålet om den norske idrettsmodellen er i utakt med tiden. Vi svarer ja på spørsmålet. Dette skyldes en utdatert måte å tenke idrett og politikk på. Det foreligger en kulturell fortelling – den norske idrettsmodellen – som hindrer innsikt i og forståelse for nye trender og endringer i befolkningens fysiske og idrettslige utfoldelse. Idrettsmodellen tar utgangspunkt i at ...

      This paper discusses psychomotor development in early childhood and consists of three parts. The first part is a brief historical overview of the theoretical description and analysis of movement. The second part gives an overview of the variety of movement therapies and activity methods, which are effective in kindergarten work. The third part of the paper is an attempt to analyse and to reflect on ...
    • Effects of school-based intervention program on motor performance skills 

      Mathisen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-26)
      The purpose of this study was to identify the effects of a four-week intervention program on motor skill performance in primary school children. Twenty-one children with mean age of 6.5 ± 0.7 years participated. The experimental group (EG) followed a specific movement program in three basic tasks: throwing, climbing, and jumping. The control group (CG) carried out an ordinary physical education ...

      Thermal conductivity and thermal diffusivity of ionic liquids (ILs) are investigated in this work. A hot disk method for ILs thermal conductivity and thermal diffusivity measurement is utilized. Firstly, the thermal conductivity of water is measured to check the reliability of the hot disk method. In addition, the thermal conductivity of pure ILs, including BmimBF<sub>4</sub>, BmimPF<sub>6</sub>, ...
    • Evening melatonin in January after changes in hours of habitual exercise during fall among youths living in the subarctic. 

      Weydahl, Andi (Journal article; Tidsskriftartikkel; Peer reviewed, 1994)
      Secretion of the hormone melatonin shows a circadian rhythm and is inhibited by light. Light therapy with phase shifting of the melatonin rhythm has been used as treatment of sleeping problems and seasonal affective disorders (SAD). Exercise has also been shown to suppress the melatonin secretion. In order to investigate the effect of increased level of habitual physical activity upon ...
