Attitudes toward and motivation for PE: who collects the benefits of the subject?
(Journal article; Peer reviewed, 2014-04-07)Background and purpose: Due to attitudinal and motivational aims in the national curriculum, and to lack of research on adolescents' experiences with physical education (PE) in Norway, the purposes of this study were to ... -
Body fat measurement in adolescent girls with type 1 diabetes: a comparison of skinfold equations against dual-energy X-ray absorptiometry
(Journal article; Peer reviewed, 2016-04-06)Aim: Skinfold measurement is an inexpensive and widely used technique for assessing the percentage of body fat (%BF). This study assessed the accuracy of prediction equations for %BF based on skinfold measurements compared ... -
Changes in time-segment specific physical activity between ages 10 and 14 years: A longitudinal observational study
(Journal article; Peer reviewed, 2016-01)Objectives: Describe (1) time-segment specific changes in physical activity (PA) into adolescence, (2) differences in change in PA between specific time-segments (weekdays–weekends, in-school–out-of-school, out-of-school–weekends, ... -
A closer look at the relationship among accelerometer-based physical activity metrics: ICAD pooled data
(Peer reviewed; Journal article, 2019)Background: Accelerometers are widely used to assess child physical activity (PA) levels. Using the accelerometer data, several PA metrics can be estimated. Knowledge about the relationships between these different metrics ... -
Cross-sectional associations of objectively measured physical activity with brain-derived neurotrophic factor in adolescents
(Journal article; Peer reviewed, 2017)Objective: The purpose of this study was to examine the associations between objectively measured physical activity and serum brain-derived neurotrophic factor (BDNF) in adolescents. Methods: Cross-sectional analyses were ... -
Development of positive emotions in physical education: Person-centered approach for understanding motivational stability and change
(Peer reviewed; Journal article, 2019)A person-centered exploration of positive emotions in relation to selfdetermination theory might shed light on the hidden dynamics in the motivational processes in physical education (PE). In the present longitudinal study, ... -
