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 ... -
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, ... -
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 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 ... -
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 ... -
Joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality: A harmonised meta-analysis in more than 44 000 middle-aged and older individuals
(Peer reviewed; Journal article, 2020)Objectives: To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods: We conducted a harmonised meta-analysis including nine prospective cohort ... -
Kinematic differences between uphill roller skiing and on-snow skiing using the V2 skating technique
(Peer reviewed; Journal article, 2022)Purpose: Roller skiing is the primary sport-specific training and testing mode during pre-competition periods for cross-country skiers, biathletes, and Nordic combined athletes. The present study aimed to compare the ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
(Peer reviewed; Journal article, 2019)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 and youth: An International Children's Accelerometry Database (ICAD) analysis
(Peer reviewed; Journal article, 2020)There is solid evidence for an association between physical activity and metabolic health outcomes in children and youth, but for methodological reasons most studies describe the intensity spectrum using only a few summary ... -
Objective and Self-Reported Physical Activity and Risk of Falling Among Community-Dwelling Older Adults From Southern Brazil
(Peer reviewed; Journal article, 2022)This study evaluated prospective associations between self-reported and objectively measured physical activity (PA) and risk of falls among older adults. A cohort study started in 2014 with 1,451 community-dwelling older ... -
