The present study was designed to assess the psycho-physiological responses of physically untrained individuals to mobile-based multi-stimulating, circuit-like, multiplejoint conditioning (Circuit_HIIT) performed either once (1xCircuit_HIIT) or twice (2xCircuit_HIIT) daily for 4 weeks. In this single-center, two-arm randomized, controlled study, 24 men and women (age: ...

<p><i>Objectives</i>: (1) to examine accelerations and high intensity running (HIR) in football field referees (FR) and assistant referees (AR) during football matches and (2) to evaluate fluctuations in accelerations and HIR between first and second half and in 5-min periods.</p> <p><i>Methods</i>: All movements of the referees were measured using a radio-based tracking system during 41 matches ...

Hensikt: Hensikten med denne studien var å få frem kunnskap om grunnskoleelevers fysiske aktivitetsnivå, aktivitetsmønster og aktivitetsvaner i samiske majoritetskommuner. Dette ble kartlagt ved å undersøke hvor stor andel av 6-, 9- og 15-åringer som tilfredsstiller anbefalingen om minimum 60 minutters moderat intensiv daglig fysisk aktivitet og redusert stillesitting, samt å finne ut hva som ...

Although commonly associated with cardiovascular disease or other medical conditions, atrial fibrillation may also occur in individuals without any known underlying conditions. This manifestation of atrial fibrillation has been linked to extensive and long-term exercise, as prolonged endurance exercise has shown to increase prevalence and risk of atrial fibrillation. In contrast, more modest physical ...

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), ...

9 av 10 som omkommer i snøskred utløste selv skredet. Å forbedre beslutningene i forkant av en ulykke kan derfor være livbergende. Hvordan vi driver opplæring i skredfaget er derfor viktig. Tidligere studier har sett på hvilke faktorer eksperter ser som relevante og benytter i sin beslutningstaking. Denne studien ser på hvilke faktorer nybegynnere bruker og ser på som viktige etter at de har gjennomført ...

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 ...

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 ...

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> ...

Like many other mountainous countries, Norway has experienced a rapid increase in both recreational winter activities and fatalities in avalanche terrain during the past few decades: during the decade 2008–2017, 64 recreational avalanche fatalities were recorded in Norway. This is a 106% increase from that of the previous decade. In 2013, Norway therefore launched the National Avalanche Warning ...
