A longitudinal analysis of the relationships of physical activity and body fat with nerve growth factor and brain-derived neural factor in children
Arvidsson, Daniel; Johannesson, Elias; Andersen, Lars Bo; Karlsson, Magnus; Wollmer, Per; Thorsson, Ola; Dencker, Magnus (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 ... -
The ActiGraph counts processing and the assessment of vigorous activity
Brønd, Jan Christian; Aadland, Eivind; Andersen, Lars Bo; Resaland, Geir Kåre; Anderssen, Sigmund Alfred; Arvidsson, Daniel (Peer reviewed; Journal article, 2019)The purpose of this study was to investigate the effect of different band‐pass filters on the measurement bias with ActiGraph counts during high speed running and for estimating free‐living vigorous physical activity (VPA). ... -
Galectin-3 levels relate in children to total body fat, abdominal fat, body fat distribution, and cardiac size
Dencker, Magnus; Arvidsson, Daniel; Karlsson, Magnus K.; Wollmer, Per; Andersen, Lars Bo; Thorsson, Ola (Journal article; Peer reviewed, 2018)Galectin-3 has recently been proposed as a novel biomarker for cardiovascular disease in adults. The purpose of this investigation was to assess relationships between galectin-3 levels and total body fat, abdominal fat, ... -
Generating actiGraph counts from raw acceleration recorded by an alternative monitor
Brønd, Jan Christian; Andersen, Lars Bo; Arvidsson, Daniel (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. ... -
Physical activity spectrum discriminant analysis—A method to compare detailed patterns between groups
Fridolfsson, Jonatan; Arvidsson, Daniel; Andersen, Lars Bo; Thorsson, Ola; Wollmer, Per; Rosengren, Björn; Karlsson, Magnus K.; Dencker, Magnus (Peer reviewed; Journal article, 2021)Investigating physical activity (PA) patterns as a detailed intensity spectrum instead of crude intensity categories have improved the ability to analyze the relationship between measured PA and health variables. The aim ... -
Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity
Arvidsson, Daniel; Fridolfsson, Jonatan; Börjesson, Mats; Andersen, Lars Bo; Ekblom, Örjan; Dencker, Magnus; Brønd, Jan Christian (Peer reviewed; Journal article, 2019)This review re‐examines the use of accelerometer and oxygen uptake data for the assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency ... -
Simple Method for the Objective Activity Type Assessment with Preschoolers, Children and Adolescents
Brønd, Jan Christian; Grøntved, Anders; Andersen, Lars Bo; Arvidsson, Daniel; Olesen, Line Grønholt (Peer reviewed; Journal article, 2020)Background: The objective and accurate assessment of children’s sedentary and physical behavior is important for investigating their relation to health. The purpose of this study is to validate a simple and robust method ... -
Validation of SenseWear Armband in children, adolescents, and adults
Lopez, Garcia; Brønd, Jan Christian; Andersen, Lars Bo; Dencker, Magnus; Arvidsson, Daniel (Journal article; Peer reviewed, 2017)SenseWear Armband (SW) is a multisensor monitor to assess physical activity and energy expenditure. Its prediction algorithms have been updated periodically. The aim was to validate SW in children, adolescents, and adults. ...
