A holistic approach to study the temporal variability in gait
(Journal article; Peer reviewed, 2012-04)Movement variability has become an important field of research and has been studied to gain a better understanding of the neuro-muscular control of human movements. In addition to studies investigating “amplitude variability” ... -
Cardiometabolic associations between physical activity, adiposity, and lipoprotein subclasses in prepubertal Norwegian children
(Peer reviewed; Journal article, 2021)Lipoprotein subclasses possess crucial cardiometabolic information. Due to strong multicollinearity among variables, little is known about the strength of influence of physical activity (PA) and adiposity upon this ... -
Heel-strike in walking: Assessment of potential sources of intra- and inter-subject variability in the activation patterns of muscles stabilizing the knee joint
(Journal article; Peer reviewed, 2013-04-26)The electromyographic (EMG) signal is known to show large intra-subject and inter-subject variability. Adaptation to, and preparation for, the heel-strike event have been hypothesized to be major sources of EMG variability ... -
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 ... -
Shoe midsole hardness, sex and age effects on lower extremity kinematics during running
(Journal article; Peer reviewed, 2012-06)Previous studies investigating the effects of shoe midsole hardness on running kinematics have often used male subjects from within a narrow age range. It is unknown whether shoe midsole hardness has the same kinematic ... -
Technique analysis in elite athletes using principal component analysis
(Journal article; Peer reviewed, 2018)The aim of this study was to advance current movement analysis methodology to enable a technique analysis in sports facilitating (1) concurrent comparison of the techniques between several athletes; (2) identification of ...
