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 ... -
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 ... -
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 ... -
End criteria for reaching maximal oxygen uptake must be strict and adjusted to sex and age: a cross-sectional study
(Journal article; Peer reviewed, 2014-01-14)Objective: To describe different end criteria for reaching maximal oxygen uptake (VO2max) during a continuous graded exercise test on the treadmill, and to explore the manner by which different end criteria have an impact ... -
Estimation of free-living energy expenditure by heart rate and movement sensing: a doubly-labelled water study.
(Journal article; Peer reviewed, 2015-09-08)Background: Accurate assessment of energy expenditure (EE) is important for the study of energy balance and metabolic disorders. Combined heart rate (HR) and acceleration (ACC) sensing may increase precision of physical ... -
Identification and validation of novel contraction-regulated myokines released from primary human skeletal muscle cells
(Journal article; Peer reviewed, 2013-04-24)Proteins secreted by skeletal muscle, so called myokines, have been shown to affect muscle physiology and additionally exert systemic effects on other tissues and organs. Although recent profiling studies have identified ... -
Increased Plin2 expression in human skeletal muscle is associated with sarcopenia and muscle weakness
(Journal article; Peer reviewed, 2013-08-15)Human aging is associated with a progressive loss of muscle mass and strength and a concomitant fat accumulation in form of inter-muscular adipose tissue, causing skeletal muscle function decline and immobilization. Fat ... -
Organized sport participation is associated with higher levels of overall health-related physical activity in children (CHAMPS study-DK)
(Journal article; Peer reviewed, 2015-08-11)Introduction: Many children fail to meet international guideline recommendations for health-related activity (≥60 minutes/day of moderate-to-vigorous physical activity [MVPA]), and intervention studies to date have ... -
Physical activity in adults and older people: levels of objectively measured physical activity in a population-based sample of Norwegian adults and older people (20-85 years)
(Doctoral thesis, 2013)Evidence from epidemiological research and clinical interventions clearly states that physical activity is essential to improve health as well as quality of life. The health gains of increasing physical activity are ... -
Physical activity level, musculoskeletal fitness,balance, strength and power performance in older adults
(Doctoral thesis, 2015)The link between physical activity and prevention of disease, maintenance of independence, and improved quality of life in older adults is supported by strong evidence. However, there is a lack of data on population levels ... -
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 ... -
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 ... -
Young & Active: development and evaluation of an internet intervention to increase fitness and health-related quality of life in adolescents with overweight and obesity
(Doctoral thesis, 2015)Overweight and obesity among adolescents may have consequences with potentially lasting effects on health and health-related quality of life (HRQoL). Excess weight is also associated with decreases in physical activity ...
