  • Position specific player load during match-play in a professional football club 

    Baptista, Ivan; Johansen, Dag; Seabra, André; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
    There is a rapid growing body of knowledge regarding physical aspects of a football match due to studies using computer-assisted motion analysis. The present study used time-motion analysis and triaxial-accelerometers to obtain new insights about differences in physical profiles of elite football players across playing-positions. Player performance data in 23 official home matches from a professional ...
  • Learning leadership: becoming an outdoor leader 

    Enoksen, Elisabeth; Lynch, Pip (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-19)
    Recent leadership research has demonstrated a need for better understanding the process of becoming a leader because it might be qualitatively different to being a leader. If so, there is likely to be a need for pedagogies designed deliberately to support first-time outdoor leadership experiences and any such pedagogies must be informed by the needs of first-time leaders. Becoming a leader in outdoor ...
  • 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 ...
  • Identitetsdribling i samisk fotball. En kvalitativ studie av samisk selvforståelse i samisk idrett 

    Sandberg, Odd Inge (Master thesis; Mastergradsoppgave, 2018-05-21)
    I denne masteroppgaven har jeg sett på hvilke måter samiske identitetskonstruksjoner utrykkes, bekreftetes og forhandles i samiske idrettskonkurranser blant utøverne. Jeg har videre sett på hvordan ulike samiske markører for samisk identitet bidrar til å styrke og utfordre idrettsutøvernes selvidentiet. Forskningen er gjennomført som en kvalitativ studie med intervjuer av fem mannlige fotballspillere ...

  • Should we be recommending altitude training to swimmers? 

    Winther, Andreas Kjæreng (Master thesis; Mastergradsoppgave, 2018-05-15)
    Many swimmers continue to use altitude training as part of their preparation despite questions of its efficacy. This belief seems to be strongly tied to the notion that an increase in hemoglobin mass will transfer over to increased sea-level performance. The purpose of the presents study was to examine whether altitude training lead to greater increases in competitive performance compared to sea-level ...
  • Technique and performance in classical cross-country skiing. How does different sub-techniques influence physiological responses and performance at steep uphill terrain? 

    Engseth, Tina Pettersen (Master thesis; Mastergradsoppgave, 2018-05-15)
    Background: The double poling technique has developed and further created a debate in the cross-country sport. Several athletes have seen that use of double poling without kick wax under their skis, has greater advantages than challenges in many of the trails used in competitions today. Various initiatives have therefore been put in place to ensure that diagonal stride technique retains in the ...
  • BONUS - Eldres erfaringer ved langvarig deltakelse i gruppetrening. En undersøkelse av en gruppe eldres helserelaterte livskvalitet og hvilke faktorer som var verdsatt ved deltakelse i gruppetrening

  • 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 ...

    Düking, Peter; Holmberg, Hans-Christer; Sperlich, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-03)
    With great interest, we have been following the developing variety and popularity of commercially available wearable sensor technologies, as well as the discussion concerning their usefulness for improving fitness and health (Duking et al., 2016; Halson et al., 2016; Sperlich and Holmberg,2016). Although many of these devices may not necessarily fulfill scientific criteria for quality (Sperlich and ...

  • 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 ...
  • The pacing strategy and technique of male cross-country skiers With different levels of performance during a 15-km classical race
