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 ...

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> ...

Our research takes place at 70oN. Where the sun is above the horizon for 8 weeks during summer, midnight sun and below the horizon for 8 weeks during winter, polar night. Earlier we found that adults with different chronotypes responded differently to exercise performed in day-light or darkness1. During the polar night evening (E) and neither (N) -types respond to training better than morning (M) ...

Thermal conductivity and thermal diffusivity of ionic liquids (ILs) are investigated in this work. A hot disk method for ILs thermal conductivity and thermal diffusivity measurement is utilized. Firstly, the thermal conductivity of water is measured to check the reliability of the hot disk method. In addition, the thermal conductivity of pure ILs, including BmimBF₄, BmimPF₆, ...

The level of motor competence for six-year-old children are of special interest because at this age they have started at school, and they have to master new requirements. Ninety-four children were tested in fine- and gross- motor skills, by the Movement ABC test. Within the fifth percentile of the USA norms, 9.6 % of the children would have to be classified as to have motor problems, with 11.7% ...

Previous research on exercise for pre-adolescents with the purpose of improving aerobic fitness levels has yielded contradictory results. Sufficient training intensity, frequency and duration are the crucial factors in achieving this goal; the question, however, is whether it is possible to reach sufficient intensity levels using aerobic games and playful exercises. Variety and fun are the important ...

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. ...

Aims: The objective was to examine the association of physical activity and resting heart rate (RHR) with hospital-diagnosed atrial fibrillation (AF) in a Norwegian cohort. <p> Methods and Results: This prospective study included 20 484 adults (50.3% men) who participated in the third Tromsø Study survey in 1986-1987. At baseline, physical activity was assessed by a validated questionnaire, and ...

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), ...
