Videre har vi sammenlignet de ulike instrumentene brukt i observasjonen. De ansatte i barnehagen ...
    • Biological rhythms, chronodisruption and chrono-enhancement: The role of physical activity as synchronizer in correcting steroids circadian rhythm in metabolic dysfunctions and cancer 

      Vitale, Jacopo Antonino; Lombardi, Giovanni; Weydahl, Andi; Banfi, Giuseppe (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-28)
      Rhythms can be observed at all levels of the biologic integration in humans. The observation that a biological or physiological variable shows a circadian rhythm can be explained by several multifactorial systems including external (exogenous), internal (endogenous) and psychobiological (lifestyle) mechanisms. Our body clock can be synchronized with the environment by external factors, called ...

    • 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 ...

      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 ...
