Absentee rates in physical education in high schools: The importance of gender and study programmes
(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 ... -

Position specific player load during match-play in a professional football club
(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
(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
(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
(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?
(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 ... -
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
(Master thesis; Mastergradsoppgave, 2018-05-13)Hensikten var å få kartlagt hvilken helserelatert livskvalitet eldre deltakere i et bestemt treningstilbud opplevde, samt å få kunnskap om hvilke faktorer medlemmene verdsatte ved gruppetreningstilbudet. Dette ble undersøkt gjennom å måle livskvalitet og intervjue medlemmer ved et treningstilbud. Utvalget besto av 38 deltakere fra et treningstilbud i Tromsø. Gjennomsnittsalder var 79,1 år. Metodisk ... -
Evening melatonin in January after changes in hours of habitual exercise during fall among youths living in the subarctic.
(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 ... -

As editors of both of these topics, we would like to share some ... -
Instant Biofeedback Provided by Wearable Sensor Technology Can Help to Optimize Exercise and Prevent Injury and Overuse
(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?
(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 ... -
