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 ...

This study compared the effects of long (4×4 min) and short intervals (4×8×20 s) of high-intensity interval exercise bouts (HIIT) on running performance, physiological and perceptual responses, and excess postexercise oxygen consumption (EPOC). Twelve healthy college students (8 men, 4 women; mean age=22±2 years) performed long (90–95% of peak heart rate) and short intervals (maximal intensity) of ...

Abstract Introduction: Despite the broad consensus on the importance of training load monitoring and management for footballers’ performance, existing research on female football players remains scarce. The present study aimed to develop and evaluate a linear mixed model (LMM) to predict the rating of perceived exertion (RPE) and session RPE (sRPE) in female elite football players using GPS-derived ...

Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast ...

The aim of this study was to estimate the effect of body composition on match physical performance in highly trained male football players. For this purpose, body composition and match physical performance were collected over a five-month period from a Norwegian men´s team playing in the top division during the 2021 season. Dual energy X-ray absorptiometry (DXA) was used to collect information ...
