Predicting missing marker trajectories in human motion data using marker intercorrelations
(Journal article; Peer reviewed, 2016-03-31)Missing information in motion capture data caused by occlusion or detachment of markers is a common problem that is difficult to avoid entirely. The aim of this study was to develop and test an algorithm for reconstruction ... -
Predictive validity and classification accuracy of actigraph energy expenditure equations and cut-points in young children
(Journal article; Peer reviewed, 2013-11-11)Objectives: Evaluate the predictive validity of ActiGraph energy expenditure equations and the classification accuracy of physical activity intensity cut-points in preschoolers. Methods: Forty children aged 4–6 years ... -
The relationship between the relative age effect and performance among athletes in World Handball Championships
(Peer reviewed; Journal article, 2020)This study examines the relative age effect (RAE) and its impact on the performance of elite male (n = 3,358) and female (n = 3,273) handball players in the U-19 (n = 2,188), U-21 (n = 2,031), and senior (n = 2,412) ... -
Reproducibility of objectively measured physical activity and sedentary time over two seasons in children; Comparing a day-by-day and a week-by-week approach
(Peer reviewed; Journal article, 2017)Introduction: Knowledge of reproducibility of accelerometer-determined physical activity (PA) and sedentary time (SED) estimates are a prerequisite to conduct high-quality epidemiological studies. Yet, estimates of ... -
Sedentary behavior and incident cancer: a meta-analysis of prospective studies
(Journal article; Peer reviewed, 2014-08-25)Sedentary behavior is ubiquitous in modern adults' daily lives and it has been suggested to be associated with incident cancer. However, the results have been inconsistent. In this study, we performed a systematic review ... -
Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity
(Journal article; Peer reviewed, 2013-04-23)Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes ... -
Simple muscle architecture analysis (SMA): An ImageJ macro tool to automate measurements in B-mode ultrasound scans
(Peer reviewed; Journal article, 2020)In vivo measurements of muscle architecture (i.e. the spatial arrangement of muscle fascicles) are routinely included in research and clinical settings to monitor muscle structure, function and plasticity. However, in most ... -
Sprint conditioning of junior soccer players: effects of training intensity and technique supervision
(Journal article; Peer reviewed, 2015-03-23)The aims of the present study were to compare the effects of 1) training at 90 and 100% sprint velocity and 2) supervised versus unsupervised sprint training on soccer-specific physical performance in junior soccer players. ... -
The Andersen Aerobic Fitness Test: reliability and validity in 10-year-old children
(Journal article; Peer reviewed, 2014-10-17)Background: High aerobic fitness is consistently associated with a favorable metabolic risk profile in children. Direct measurement of peak oxygen consumption (VO2peak) is often not feasible, thus indirect tests such as ... -
The association between serum brain-derived neurotrophic factor and a cluster of cardiovascular risk factors in adolescents: The CHAMPS-study DK
(Peer reviewed; Journal article, 2017)Background and objective: Cardiovascular disease and type 2 diabetes pose a global health burden. Therefore, clarifying the pathology of these risk factors is essential. Previous studies have found positive and negative ... -
The relative age effect in selection to international team matches in Norwegian handball
(Journal article; Peer reviewed, 2018)Many elite sport organisations have introduced structured talent identification and development (TID) initiatives in youth sports to better facilitate elite sport performance. However, selection mechanisms for TID programmes ... -
Training at maximal power in resisted sprinting: Optimal load determination methodology and pilot results in team sport athletes
(Journal article; Peer reviewed, 2018)Aims: In the current study we investigated the effects of resisted sprint training on sprinting performance and underlying mechanical parameters (force-velocity-power profile) based on two different training protocols: (i) ... -
Validation of energy intake from a web-based food recall for children and adolescents
(Journal article; Peer reviewed, 2017-06-08)The purpose of this study was to validate estimated energy intake from a web-based food recall, designed for children and adolescents. We directly compared energy intake to estimates of total energy expenditure, calculated ...
