Accelerometer epoch setting is decisive for associations between physical activity and metabolic health in children
Aadland, Eivind; Andersen, Lars Bo; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2020)When analysing physical activity (PA) levels using accelerometry, the epoch setting is critical to capture intensity-specific PA correctly. The aim of the present study was to investigate the PA intensity signatures related ... -
Active Smarter Kids (ASK): Rationale and design of a cluster-randomized controlled trial investigating the effects of daily physical activity on children's academic performance and risk factors for non-communicable diseases
Resaland, Geir Kåre; Moe, Vegard Fusche; Aadland, Eivind; Steene-Johannessen, Jostein; Glosvik, Øyvind; Andersen, John Roger; Kvalheim, Olav Martin; McKay, Heather A.; Anderssen, Sigmund Alfred (Peer reviewed; Journal article, 2015-07-28)Background Evidence is emerging from school-based studies that physical activity might favorably affect children’s academic performance. However, there is a need for high-quality studies to support this. Therefore, the ... -
Aerobic fitness and metabolic health in children: A clinical validation of directly measured maximal oxygen consumption versus performance measures as markers of health
Aadland, Eivind; Kvalheim, Olav Martin; Rajalahti, Tarja; Skrede, Turid; Resaland, Geir Kåre (Peer reviewed; Journal article, 2017-09)High aerobic fitness is consistently associated with a favorable metabolic health profile in children. However, measurement of oxygen uptake, regarded as the gold standard for evaluating aerobic fitness, is often not ... -
Associations of physical activity and sedentary time with lipoprotein subclasses in Norwegian schoolchildren: The Active Smarter Kids (ASK) study
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (Journal article; Peer reviewed, 2019)Background and aims: Physical activity is favourably associated with certain markers of lipid metabolism. The relationship of physical activity with lipoprotein particle profiles in children is not known. Here we examine ... -
Associations of volumes and patterns of physical activity with metabolic health in children: A multivariate pattern analysis approach
Aadland, Eivind; Andersen, Lars Bo; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2018)Physical activity (PA) favorably affects metabolic health in children, but it is unclear how total volumes versus patterns (bouts and breaks) of PA relate to health. By means of multivariate pattern analysis that can handle ... -
Effects of physical activity on schoolchildren's academic performance: The Active Smarter Kids (ASK) cluster-randomized controlled trial
Resaland, Geir Kåre; Aadland, Eivind; Moe, Vegard Fusche; Aadland, Katrine Nyvoll; Skrede, Turid; Stavnsbo, Mette; Suominen, Laura; Steene-Johannessen, Jostein; Glosvik, Øyvind; Andersen, John Roger; Kvalheim, Olav Martin; Engelsrud, Gunn; Andersen, Lars Bo; Holme, Ingar Morten K; Ommundsen, Yngvar; Kriemler, Susi; van Mechelen, Willem; McKay, Heather A.; Ekelund, Ulf; Anderssen, Sigmund Alfred (Peer reviewed; Journal article, 2016-10)Objective. To investigate the effect of a seven-month, school-based cluster-randomized controlled trial on academic performance in 10-year-old children. Methods. In total, 1129 fifth-grade children from 57 elementary schools ... -
Interpretation of multivariate association patterns between multicollinear physical activity accelerometry data and cardiometabolic health in children-a tutorial
Aadland, Eivind; Andersen, Lars Bo; Resaland, Geir Kåre; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2019-07-02)Associations between multicollinear accelerometry-derived physical activity (PA) data and cardiometabolic health in children needs to be analyzed using an approach that can handle collinearity among the explanatory variables. ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
Aadland, Eivind; Kvalheim, Olav Martin; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Andersen, Lars Bo (Peer reviewed; Journal article, 2019-08-27)Background: The analysis of associations between accelerometer-derived physical activity (PA) intensities and cardiometabolic health is a major challenge due to multicollinearity between the explanatory variables. This ... -
The multivariate physical activity signature associated with metabolic health in children
Aadland, Eivind; Kvalheim, Olav Martin; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Andersen, Lars Bo (Peer reviewed; Journal article, 2018-08-15)Background. Physical activity is a cornerstone for promoting good metabolic health in children, but it is heavily debated which intensities (including sedentary time) are most influential. A fundamental limitation to current ...
