A novel approach to solve the “Missing marker problem” in marker-based motion analysis that exploits the segment coordination patterns in multi-limb motion data
(Journal article; Peer reviewed, 2013-10-30)Marker-based human motion analysis is an important tool in clinical research and in many practical applications. Missing marker information caused by occlusions or a marker falling off is a common problem impairing data ... -
A randomized controlled trial on the effectiveness of strength training on clinical and muscle cellular outcomes in patients with prostate cancer during androgen deprivation therapy: rationale and design
(Journal article; Peer reviewed, 2012-03-29)Background Studies indicate that strength training has beneficial effects on clinical health outcomes in prostate cancer patients during androgen deprivation therapy. However, randomized controlled trials are needed to ... -
Active recovery training does not affect the antioxidant response to soccer games in elite female players
(Journal article; Peer reviewed, 2010-07-08)Changes in plasma endogenous and dietary antioxidants and oxidative stress markers were studied following two 90 min elite female soccer games separated by 72 h of either active or passive recovery. The active recovery ... -
Altitude and endurance athletes : effects of acute and chronic hypoxic exposure
(Doctoral thesis, 2008)“How does altitude affect performance"? This question has been asked by athletes, coaches and sport scientists for many years. Most of the current interest in altitude and altitude training can be traced back to the 1968 ... -
Antioxidants in Translational Medicine
(Journal article; Peer reviewed, 2015-08-31)Significance: It is generally accepted that reactive oxygen species (ROS) scavenging molecules or antioxidants exert health-promoting effects and thus their consumption as food additives and nutraceuticals has been greatly ... -
Body fat related to daily physical activity and insulin concentrations in non-diabetic children
(Peer reviewed; Journal article, 2008-06-28)This study explored the associations between body fat versus daily physical activity and insulin concentrations in non-diabetic young children in a cross-sectional study of 172 children (93 boys and 79 girls) aged 8–11 ... -
Cardiopulmonary exercise testing in health and disease: cardiorespiratory fitness in adults in Norway and in lung cancer patients undergoing surgery
(Doctoral thesis, 2015)Maximal oxygen uptake (VO2max) is used to quantify an individual’s exercise capacity and is recognized as the main variable for measurement during cardiopulmonary exercise testing (CPET). There are limited reference values ... -
Characterization of course and terrain and their effect on skier speed in World Cup alpine ski racing.
(Journal article; Peer reviewed, 2015-03-11)World Cup (WC) alpine ski racing consists of four main competition disciplines (slalom, giant slalom, super-G and downhill), each with specific course and terrain characteristics. The International Ski Federation (FIS) has ... -
Comparison of the EPIC physical activity questionnaire with combined heart rate and movement sensing in a nationally representative sample of older British adults
(Journal article; Peer reviewed, 2014-02-06)Objectives: To compare physical activity (PA) subcomponents from EPIC Physical Activity Questionnaire (EPAQ2) and combined heart rate and movement sensing in older adults. Methods: Participants aged 60–64y from the MRC ... -
Costamere remodeling with muscle loading and unloading in healthy young men
(Journal article; Peer reviewed, 2013-09-08)Costameres are mechano-sensory sites of focal adhesion in the sarcolemma that provide a structural anchor for myofibrils. Their turnover is regulated by integrin-associated focal adhesion kinase (FAK). We hypothesized that ... -
Dietary arginine and linear growth: the Copenhagen School Child Intervention Study
(Journal article; Peer reviewed, 2012-10-10)The amino acid arginine is a well-known growth hormone (GH) stimulator and GH is an important modulator of linear growth. The aim of the present study was to investigate the effect of dietary arginine on growth velocity ... -
Does birth weight influence physical activity in youth? a combined analysis of four studies using objectively measured physical activity
(Journal article; Peer reviewed, 2011-01-12)Animal models suggest growth restriction in utero leads to lower levels of motor activity. Furthermore, individuals with very low birth weight report lower levels of physical activity as adults. The aim of this study was ... -
Effect of heavy strength training on thigh muscle cross-sectional area, performance determinants, and performance in well-trained cyclists
(Journal article; Peer reviewed, 2009-12)The purpose of this study was to investigate the effect of heavy strength training on thigh muscle cross-sectional area (CSA), determinants of cycling performance, and cycling performance in well-trained cyclists. Twenty ... -
Effect of range of motion in heavy load squatting on muscle and tendon adaptations
(Journal article; Peer reviewed, 2013-04-20)Manipulating joint range of motion during squat training may have differential effects on adaptations to strength training with implications for sports and rehabilitation. Consequently, the purpose of this study was to ... -
Effects of an acute bout of low-load resistance training with blood flow restriction: -with special reference to muscle damage, hypertrophic signaling and satellite cells
(Doctoral thesis, 2011)Main findings: Blood flow restriction reduces muscle endurance at low exercise loads (20-40% of 1RM) but not necessarily at moderate to higher loads (>50% of 1RM) in the knee extension exercise. The intramuscular pressures ... -
Effects of strength training for prostate cancer patients during androgen deprivation therapy
(Doctoral thesis, 2015)Androgen deprivation therapy (ADT) increases survival rates among prostate cancer (PCa) patients with locally advanced disease, but is associated with side effects that may impair daily function through negative effects ... -
