Aerobic fitness and metabolic health in children: A clinical validation of directly measured maximal oxygen consumption versus performance measures as markers of health
Aadland, Eivind; Kvalheim, Olav Martin; Rajalahti, Tarja; Skrede, Turid; Resaland, Geir Kåre (Peer reviewed; Journal article, 2017)High aerobic fitness is consistently associated with a favorable metabolic health profile in children. However, measurement of oxygen uptake, regarded as the gold standard for evaluating aerobic fitness, is often not ... -
An approach to assess and adjust for the influence of multicollinear covariates on metabolomics association patterns - applied to a study of the associations between a comprehensive lipoprotein profile and the homeostatic model assessment of insulin resistance
Kvalheim, Olav Martin; Rajalahti, Tarja; Aadland, Eivind (Peer reviewed; Journal article, 2022)Introduction Comprehensive lipoprotein profiling using proton nuclear magnetic resonance (NMR) spectroscopy of serum represents an alternative to the homeostatic model assessment of insulin resistance (HOMA-IR). Both ... -
Associations of lipoprotein particle profile and objectively measured physical activity and sedentary time in schoolchildren: a prospective cohort study
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (Peer reviewed; Journal article, 2022)Background: Our understanding of the mechanisms through which physical activity might benefit lipoprotein metabolism is inadequate. Here we characterise the continuous associations between physical activity of different ... -
Associations of physical activity and sedentary time with lipoprotein subclasses in Norwegian schoolchildren: The Active Smarter Kids (ASK) study
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (Peer reviewed; Journal article, 2019)Background and aims: Physical activity is favourably associated with certain markers of lipid metabolism. The relationship of physical activity with lipoprotein particle profiles in children is not known. Here we examine ... -
Cardiometabolic associations between physical activity, adiposity, and lipoprotein subclasses in prepubertal norwegian children
Rajalahti, Tarja; Aadland, Eivind; Resaland, Geir Kåre; Anderssen, Sigmund Alfred; Kvalheim, Olav Martin (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 ... -
Cross-sectional and prospective associations between aerobic fitness and lipoprotein particle profile in a cohort of Norwegian schoolchildren
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (Journal article; Peer reviewed, 2021)Background and aims The associations between aerobic fitness and traditional measures of lipid metabolism in children are uncertain. We investigated whether higher levels of aerobic fitness benefit lipoprotein metabolism ... -
Influence of adiposity and physical activity on the cardiometabolic association pattern of lipoprotein subclasses to aerobic fitness in prepubertal children
Rajalahti, Tarja; Aadland, Eivind; Resaland, Geir Kåre; Anderssen, Sigmund Alfred; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2021)Aerobic fitness (AF) and lipoprotein subclasses associate to each other and to cardiovascular health. Adiposity and physical activity (PA) influence the association pattern of AF to lipoproteins almost inversely making it ...
