A longitudinal analysis of the relationships of physical activity and body fat with nerve growth factor and brain-derived neural factor in children
(Journal article; Peer reviewed, 2018)Background: Nerve growth factor (NGF) and brain-derived neural factor (BDNF) are important for brain function and detectable in the blood. This study explored the longitudinal associations of physical activity and body fat ... -
Accelerometer epoch setting is decisive for associations between physical activity and metabolic health in children
(Journal article; Peer reviewed, 2019)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 Learning Norwegian Preschool(er)s (ACTNOW) – Design of a Cluster Randomized Controlled Trial of Staff Professional Development to Promote Physical Activity, Motor Skills, and Cognition in Preschoolers [Study protocol]
(Peer reviewed; Journal article, 2020)Introduction: There is a dearth of high-quality evidence on effective, sustainable, and scalable interventions to increase physical activity (PA) and concomitant outcomes in preschoolers. Specifically, there is a need to ... -
Aerobic fitness thresholds to define poor cardiometabolic health in children and youth
(Journal article; Peer reviewed, 2018)Aerobic fitness is an apparent candidate for screening children and youth for poor cardiometabolic health and future risk of cardiovascular disease (CVD). Yet, age‐ and sex‐specific cut points for children and youth ... -
The association between physical fitness and mental health in Norwegian adolescents
(Peer reviewed; Journal article, 2020)Background Studies indicate that health-related components of physical fitness are associated with mental health outcomes. However, research is scarce concerning this relationship in young adolescents in general and ... -
Associations of volumes and patterns of physical activity with metabolic health in children: A multivariate pattern analysis approach
(Journal article; Peer reviewed, 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 ... -
Cardiometabolic risk factor levels in Norwegian children compared to international reference values: The ASK study
(Journal article; Peer reviewed, 2019)Objective To investigate cardiometabolic risk factor levels in a group of Norwegian 10-year-old children compared to international values and examine the association between cardiorespiratory fitness (CRF) and the ... -
The causal pathway effects of a physical activity intervention on adiposity in children: The KISS Study cluster randomized clinical trial
(Peer reviewed; Journal article, 2020)Background Very little information on the potential mechanisms of the physical activity interventions effects on adiposity is available. We evaluated the possible mediating factors of a physical activity school‐based ... -
Cross-sectional and prospective associations between physical activity, body mass index and waist circumference in children and adolescents
(Journal article; Peer reviewed, 2017)Objective: To study the cross-sectional and prospective associations between physical activity (PA) of different intensities, body mass index (BMI) and waist circumference (WC) in children and adolescents using isotemporal ... -
Cross-sectional and prospective associations between sleep, screen time, active school travel, sports/exercise participation and physical activity in children and adolescents
(Journal article; Peer reviewed, 2018)Background The aim of this study was to investigate how sleep, screen time, active school travel and sport and/or exercise participation associates with moderate-to-vigorous physical activity (MVPA) in nationally ... -
Cycling and walking for transport and their associations with diabetes and risk factors for cardiovascular disease
(Journal article; Peer reviewed, 2018)Introduction Active travel is recommended and promoted to increase physical activity and reduce the risk of several non-communicable diseases. The health effects of active travel in populations of low socioeconomic status ... -
Dose-response of resistance training for neck-and shoulder pain relief: A workplace intervention study
(Peer reviewed; Journal article, 2020)Background Musculoskeletal disorders are highly prevalent among office workers, with strong evidence suggesting that workplace-based resistance training programs can prevent several upper extremity musculoskeletal disorders. ... -
Effects of a physical activity intervention on schoolchildren's health-related quality of life: The active smarter kids (ASK) cluster-randomized controlled trial
(Journal article; Peer reviewed, 2018-11-07)We investigated whether a seven-month (November 2014 to June 2015), school-based cluster-randomized controlled physical activity intervention improved health-related quality of life (HRQoL) in 10-year old children. The ... -
Electromyographic comparison of five lower-limb muscles between single- and multi-joint exercises among trained men
(Peer reviewed; Journal article, 2021)Resistance-training exercises can be classified as either single- or multi-joint exercises and differences in surface electromyography (EMG) amplitude between the two training methods may identify which muscles can benefit ... -
Executive functions do not mediate prospective relations between indices of physical activity and academic performance: The Active Smarter Kids (ASK) study
(Journal article; Peer reviewed, 2017)Changes in cognitive function induced by physical activity have been proposed as a mechanism for the link between physical activity and academic performance. The aim of this study was to investigate if executive function ... -
Generating actiGraph counts from raw acceleration recorded by an alternative monitor
(Journal article; Peer reviewed, 2017)Purpose: This study aimed to implement an aggregation method in Matlab for generating ActiGraph counts from raw acceleration recorded with an alternative accelerometer device and to investigate the validity of the method. ... -
Greater short-time recovery of peripheral fatigue after short- compared with long-duration time trial
(Peer reviewed; Journal article, 2020)The kinetics of recovery from neuromuscular fatigue resulting from exercise time trials (TTs) of different durations are not well-known. The aim of this study was to determine if TTs of three different durations would ... -
