Accelerometer-determined physical activity and walking capacity in persons with Down syndrome, Williams syndrome and Prader-Willi syndrome
(Journal article; Peer reviewed, 2013-10-18)In this study we describe by use of accelerometers the total physical activity (PA), intensity pattern and walking capacity in 87 persons age 16–45 years with Down syndrome (DS), Williams syndrome (WS) and Prader–Willi ... -
Activity profile, PlayerLoad™ and heart rate response of Gaelic football players: A pilot study
(Peer reviewed; Journal article, 2019)The objectives of this study were to; quantify positional differences in the activity profiles of Gaelic football players and to evaluate decrements in physical performance during a pre-season competition. Global positioning ... -
Activity profiles in international female team handball using PlayerLoadTM
(Journal article; Peer reviewed, 2016)Team handball matches place diverse physical demands on players, which may result in fatigue and decreased activity levels. However, previous speed-based methods of quantifying player activity may not be sensitive for ... -
Associations between organized sports participation and objectively measured physical activity, sedentary time and weight status in youth
(Journal article; Peer reviewed, 2016)Objectives: The purpose of this study was to examine whether participation in organized sports is related to achieving physical activity recommendations, body mass index (BMI), objectively measured PA intensity and time ... -
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 ... -
Cardiorespiratory fitness, physical activity, and fatigue three months after first-ever ischemic stroke
(Peer reviewed; Journal article, 2024)Background: Research on cardiorespiratory fitness (CRF) in relation to physical activity (PA) and fatigue after stroke is limited. Increased knowledge of interrelationships between these factors can help optimize rehabilitation ... -
Changes in physical activity and sedentary time during adolescence: Gender differences during weekdays and weekend days
(Peer reviewed; Journal article, 2020)Objectives: The objective of this study was to determine the gender‐specific and time‐segmented changes in accelerometer measured physical activity (PA) and sedentary time (ST) during adolescence. Methods: The study ... -
Children's moderate-to-vigorous physical activity on weekdays versus weekend days: A multi-country analysis
(Peer reviewed; Journal article, 2021)Purpose: The Structured Days Hypothesis (SDH) posits that children’s behaviors associated with obesity – such as physical activity – are more favorable on days that contain more ‘structure’ (i.e., a pre-planned, segmented, ... -
Comparison of three activity monitors for estimating sedentary time among children
(Journal article; Peer reviewed, 2016-02-05)Background: Time spent sedentary appears to be associated with several health outcomes in adults, but findings are inconsistent in children. Further, the assessment of sedentary time represents a major challenge. The ... -
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 ... -
Device-measured physical activity and sedentary time in the Nordic countries: A scoping review of population-based studies
(Peer reviewed; Journal article, 2024)Purpose: The purpose of this scoping review was to summarize and describe the methodology and results from population-based studies of physical activity and sedentary time measured with devices in the Nordic countries ... -
Device-measured sedentary time in Norwegian children and adolescents in the era of ubiquitous internet access: Secular changes between 2005, 2011 and 2018
(Peer reviewed; Journal article, 2022)Background: Access to screen-based media has been revolutionized during the past two decades. How this has affected sedentary time (ST) accumulation in children is poorly understood. Methods: This study, based on the ... -
Differences in fat loss in response to physical activity among severely obese men and women
(Journal article; Peer reviewed, 2014-02-04)Background: Direct measurement of physical activity may be critical to revealing its relationship with the change in fat mass over time. The aim of this study was to determine the relationship between accelerometer-determined ... -
Evaluation of an In-Ear Sensor for Quantifying Head Impacts in Youth Soccer
(Peer reviewed; Journal article, 2019)Background: Wearable sensor systems have the potential to quantify head kinematic responses of head impacts in soccer. However, on-field use of sensors (eg, accelerometers) remains challenging, owing to poor coupling to ... -
