Cardiovascular effects of high intensity aerobic interval training in hypertensive patients, healthy aged and young persons
Hansen, Harald Edvard Mølmen (Doktoravhandlinger ved NTNU, 1503-8181; 2012:126, Doctoral thesis, 2012)I denne oppgaven ble det undersøkt effekter av høyintensiv aerob intervall trening (AIT) blant personer med høyt blodtrykk og blant friske eldre og yngre personer. AIT med høy intensitet (>90% av maksimal puls) er mer ... -
Effect of 24 sessions of high-intensity aerobic interval training carried out at either high or moderate frequency, a randomized trial
Hatle, Håvard; Støbakk, Per Kristian; Hansen, Harald Edvard Mølmen; Brønstad, Eivind; Tjønna, Arnt Erik; Steinshamn, Sigurd Loe; Skogvoll, Eirik; Wisløff, Ulrik; Ingul, Charlotte Bjørk; Rognmo, Øivind (Journal article; Peer reviewed, 2014)Purpose: The training response of an intensified period of high-intensity exercise is not clear. Therefore, we compared the cardiovascular adaptations of completing 24 high-intensity aerobic interval training sessions ... -
Importance of length and external diameter in left ventricular geometry. Normal values from the HUNT Study
Støylen, Asbjørn; Hansen, Harald Edvard Mølmen; Dalen, Håvard (Journal article; Peer reviewed, 2016)Background: We aimed to study left ventricular (LV) geometry assessed by length (LVWL), external diameter (LVEDD) and relative wall thickness (RWT) in relation to age, body size and gender in healthy individuals. Methods: ... -
Left ventricular global strains by linear measurements in three dimensions: interrelations and relations to age, gender and body size in the HUNT Study
Støylen, Asbjørn; Hansen, Harald Edvard Mølmen; Dalen, Håvard (Journal article; Peer reviewed, 2019)Strain is a relative deformation and has three dimensions, in the left ventricle (LV) usually longitudinal (εL), transmural (εT) and circumferential (εC) strain. All three components can be measured generically by the basic ... -
Left ventricular longitudinal shortening: relation to stroke volume and ejection fraction in ageing, blood pressure, body size and gender in the HUNT3 study
Støylen, Asbjørn; Dalen, Håvard; Hansen, Harald Edvard Mølmen (Peer reviewed; Journal article, 2020)Background: Aims of this cross-sectional study were to assess: the relative contribution of left ventricular (LV) systolic long-axis shortening (mean mitral annular plane systolic excursion, MAPSE) to stroke volume (SV), ... -

Støylen, Asbjørn; Dalen, Håvard; Hansen, Harald Edvard Mølmen (Peer reviewed; Journal article, 2020)Background: Aims of this cross-sectional study were to assess: the relative contribution of left ventricular (LV) systolic long-axis shortening (mean mitral annular plane systolic excursion, MAPSE) to stroke volume (SV), ... -
Over all variability of mitral annular plane peak systolic velocity and peak global longitudinal strain rate in relation to age, body size, and sex: The HUNT Study
Støylen, Asbjørn; Hansen, Harald Edvard Mølmen; Dalen, Håvard (Peer reviewed; Journal article, 2020)BACKGROUND: Left ventricular (LV) systolic global function can be assessed by peak annular systolic velocity S'. Global longitudinal strain rate (GLSR) is relative LV shortening rate, equivalent to normalizing S' for LV ... -
Relation between mitral annular plane systolic excursion and global longitudinal strain in normal subjects: The HUNT study
Støylen, Asbjørn; Hansen, Harald Edvard Mølmen; Dalen, Håvard (Journal article; Peer reviewed, 2018)Background Left ventricular (LV) systolic long‐axis shortening can be measured as Mitral Annular Plane Systolic Excursion (MAPSE). Global longitudinal strain (GLS) is relative LV shortening, equivalent to normalizing MAPSE ...
