Comparison of non-invasive individual monitoring of the training and health of athletes with commercially available wearable technologies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-09)
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. ...
Effects of upper-body sprint-interval training on strength and endurance capacities in female cross-country skiers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-27)
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 BmimBF<sub>4</sub>, BmimPF<sub>6</sub>, ...
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 ...
Influence of different soccer-specific maximal actions on physiological, perceptual and accelerometer measurement loads
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-13)
<p><i>Background</i>:
The aim of this study was to compare the effect of different soccer-specific maximal actions (Continuous run, Sprint, Sprint with change of direction [Sprint COD], Jump and Shot) upon physiological (oxygen uptake and heart rate) and perceptual (rating of perceived exertion [RPE]) responses and accelerometer load.</p>
<p><i>Materials and methods</i>:
Ten moderately to ...
Chronotype and response to training during the polar night: a pilot study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)
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> ...
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 ...
Effects of school-based intervention program on motor performance skills
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-26)
The purpose of this study was to identify the effects of a four-week intervention program on motor skill performance in primary school children. Twenty-one children with mean age of 6.5 ± 0.7 years participated. The experimental group (EG) followed a specific movement program in three basic tasks: throwing, climbing, and jumping. The control group (CG) carried out an ordinary physical education ...
Kicking velocity and effect on match performance when using a smaller, lighter ball in women's football
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-23)
The present study evaluated the effect of a
smaller, lighter ball on kicking speed and technical-
tactical and physical match performance in
high-level adult female footballers. In the laboratory
test setting, the peak ball velocity was 6 %
higher with the new ball (NB) than the standard
ball (SB) (26.5 ± 0.5 vs. 25.1 ± 0.5 m · s − 1, p < 0.05).
However, during match-play, no differences ...
Secular trends and correlates of physical activity: The Tromsø Study 1979-2008
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-03)
<b>Background: </b>The aim was to describe secular trends in leisure time physical activity (LTPA) and work related
physical activity (WPA) from 1979 to 2008. Additionally, we explored potential cross-sectional and longitudinal
correlates of LTPA and WPA.<br>
<b>Methods:</b> Data are collected from 34,898 individuals (49.7% men) aged >20 years who participated in at least one
Tromsø Study survey ...
Physical activity, resting heart rate, and atrial fibrillation: the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-10)
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 ...
