A comparison between BMI, waist circumference, and waist-to-height ratio for identifying cardio-metabolic risk in children and adolescents
(Journal article; Peer reviewed, 2016-02-22)BACKGROUND: There is controversial evidence on the associations between anthropometric measures with clustering of cardiovascular disease risk factors in pediatric ages. We aimed to examine the associations between body ... -
A Multi-Component Day-Camp Weight-Loss Program Is Effective in Reducing BMI in Children after One Year: A Randomized Controlled Trial
(Journal article; Peer reviewed, 2016-06-30)The objective of the present study was to evaluate the effectiveness of a one-year multi-component immersive day-camp weight-loss intervention for children with overweight and obesity. The study design was a parallel-group ... -
Accelerometer-measured physical activity and sedentary time differ according to education level in young adults
(Journal article; Peer reviewed, 2016-07-12)This study examined the association of education level with objectively measured physical activity and sedentary time in young adults. Data from the Finnish ESTER study (2009– 2011) (n = 538 was used to examine the association ... -
Are sport-specific profiles of tendon stiffness and cross-sectional area determined by structural or functional integrity?
(Journal article; Peer reviewed, 2016-06-30)The present study aimed to determine whether distinct sets of tendon properties are seen in athletes engaged in sports with contrasting requirements for tendon function and structural integrity. Patellar and Achilles tendon ... -
Associations of Physical Activity, Sports Participation and Active Commuting on Mathematic Performance and Inhibitory Control in Adolescents
(Journal article; Peer reviewed, 2016-01-04)Objectives: To examine objectively measured physical activity level, organized sports participation and active commuting to school in relation to mathematic performance and inhibitory control in adolescents. Methods: The ... -
Caffeine and endurance performance in athletes
(Doctoral thesis, 2017)This thesis consists of five studies with additional unpublished results where the aim was to examine the effects of caffeine (CAF) ingestion on factors considered determining for endurance sport performance and fatigue. ... -
Correlates of light and moderate-to-vigorous objectively measured physical activity in four-year old children
(Journal article; Peer reviewed, 2013-09-05)Background: Correlates of physical activity (PA) are hypothesized to be context and behaviour specific, but there is limited evidence of this in young children. The aim of the current study is to investigate associations ... -
Determinants of Change in Children's Sedentary Time
(Journal article; Peer reviewed, 2013-06-28)Background: Understanding the determinants of sedentary time during childhood contributes to the development of effective intervention programmes. Purpose: To examine family and home-environmental determinants of 1-year ... -
Determinants of three-year change in children’s objectively measured sedentary time
(Journal article; Peer reviewed, 2016-12-12)Background: Sedentary behaviours (SB) are highly prevalent in young people and may be adversely associated with physical and mental health. Understanding of the modifiable determinants of SB is necessary to inform the ... -
Effectiveness of a School-Based Physical Activity Intervention on Cognitive Performance in Danish Adolescents: LCoMotion—Learning, Cognition and Motion – A Cluster Randomized Controlled Trial
(Journal article; Peer reviewed, 2016-06-24)Background: Physical activity is associated not only with health-related parameters, but also with cognitive and academic performance. However, no large scale school-based physical activity interventions have investigated ... -
Effects of heavy strength training on running performance and determinants of running performance in female endurance athletes
(Journal article; Peer reviewed, 2016-03-08)Purpose: The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized ... -
Effects of time of day on resistance exercise-induced anabolic signaling in skeletal muscle
(Journal article; Peer reviewed, 2012-11-12)This study examined the effect of morning versus afternoon exercise on acute responses in phosphorylation of proteins regulating muscle size and metabolism. Twenty-two untrained men, divided into the morning (n = 11) or ... -
Energy expenditure compared to physical activity measured by accelerometry and self-report in adolescents: A validation study
(Journal article; Peer reviewed, 2013-11-04)Background: Physical inactivity is responsible for 5.3 million deaths annually worldwide. To measure physical activity energy expenditure, the doubly labeled water (DLW) method is the gold standard. However, questionnaires ... -
Evidence against a beneficial effect of irisin in humans
(Journal article; Peer reviewed, 2013-09-11)Brown adipose tissue has gained interest as a potential target to treat obesity and metabolic diseases. Irisin is a newly identified hormone secreted from skeletal muscle enhancing browning of white fat cells, which improves ... -
Immediate effects of whole body vibration on patellar tendon properties and knee extension torque
(Journal article; Peer reviewed, 2016-03)Purpose: Reports about the immediate effects of whole body vibration (WBV) exposure upon torque production capacity are inconsistent. However, the changes in the torque–angle relationship observed by some authors after WBV ... -
Influence of loading rate on patellar tendon mechanical properties in vivo
(Journal article; Peer reviewed, 2014-03)Background: Rate-dependent properties of tendons have consistently been observed in vitro but in vivo studies comparing the effects of loading duration on this feature remain conflicting. The main purpose of the present ... -
Intake of protein plus carbohydrate during the first two hours after exhaustive cycling improves performance the following day
(Journal article; Peer reviewed, 2016-04-14)Intake of protein immediately after exercise stimulates protein synthesis but improved recovery of performance is not consistently observed. The primary aim of the present study was to compare performance 18 h after ... -
Local trauma in human patellar tendon leads to widespread changes in the tendon gene expression
(Journal article; Peer reviewed, 2016-05-01)Low cellular activity and slow tissue turnover in human tendon may prolong resolution of tendinopathy. This may be stimulated by moderate localized traumas such as needle penetrations, but whether this results in a widespread ... -
