Absent exercise-induced improvements in fat oxidation in women with polycystic ovary syndrome after high-intensity interval training
Lionett, Sofie Buurgaard; Kiel, Ida Almenning; Røsbjørgen, Ragnhild; Lydersen, Stian; Larsen, Steen; Moholdt, Trine (Peer reviewed; Journal article, 2021)Background: Polycystic ovary syndrome (PCOS) and metabolic inflexibility are linked to insulin resistance, and women with PCOS appear to be metabolic inflexible in the rested, insulin-stimulated state. Exercise training ... -
Aerobic interval training partly reverse contractile dysfunction and impaired Ca2+ handling in atrial myocytes from rats with post infarction heart failure
Johnsen, Anne Berit; Høydal, Morten Andre; Røsbjørgen, Ragnhild; Stølen, Tomas; Wisløff, Ulrik (Journal article; Peer reviewed, 2013)Background: There is limited knowledge about atrial myocyte Ca2+ handling in the failing hearts. The aim of this study was to examine atrial myocyte contractile function and Ca2+ handling in rats with post-infarction heart ... -
Cardiovascular Health Does Not Change Following High-Intensity Interval Training in Women with Polycystic Ovary Syndrome
Kiel, Ida Almenning; Jones, Helen; Lionett, Sofie Buurgaard; Røsbjørgen, Ragnhild; Lydersen, Stian; Vanky, Eszter; Moholdt, Trine (Peer reviewed; Journal article, 2022)Introduction: polycystic ovary syndrome (PCOS) is associated with cardiovascular disease (CVD) risk factors. First-line therapy for PCOS is lifestyle changes including exercise. We compared CVD risk factors between women ... -
Effects of “exercised plasma” on adult neurogenesis in the hippocampus of a rat model of Alzheimer’s disease
Jacobsen, Kamilla (Master thesis, 2021)Forekomsten av demens øker i sammenheng med den økende andelen eldre befolkning. I dag finnes det ingen behandlingsmuligheter for demenssykdommen med høyest prevalens, Alzheimers sykdom. For å hindre en potensiell internasjonal ... -
Exercised blood plasma promotes hippocampal neurogenesis in the Alzheimer's disease rat brain
Norevik, Cecilie Skarstad; Huuha, Aleksi Matias; Røsbjørgen, Ragnhild; Bergersen, Linda Hildegard; Jacobsen, Kamilla; Miguel dos Santos, Rodrigo; Ryan, Liv; Skender, Belma; Bianco Nascimento Moreira, Jose; Kobro-Flatmoen, Asgeir; Witter, Menno Peter; Scrimgeour, Nathan Robert; Rafiee Tari, Atefe (Peer reviewed; Journal article, 2023)Background Exercise training promotes brain plasticity and is associated with protection against cognitive impairment and Alzheimer's disease (AD). These beneficial effects may be partly mediated by blood-borne factors. ... -
Initial changes in cardiac troponins after resistance training in healthy volunteers
Eriksen, Espen Alexander (Master thesis, 2022)Sammendrag Bakgrunn: Hjertespesifikke troponiner (cTn) er biomarkører for hjertemuskelskader og øker etter hard fysisk aktivitet og utholdenhetstrening, selv blant friske individer. Få studier har undersøkt hvordan ... -
Kvantifisering av infarktstørrelse i rottehjerter
Boyaci, Berfin Gülistan; Haugen, Ingri Margrethe (Bachelor thesis, 2019)Blant pasienter som overlever hjerteinfarkt og utvikler hjertesvikt, er det årlig mange dødsfall knyttet til arytmier. Selv om behandling av arytmier er kjent, er det lite kunnskap om hvordan det kan forebygges. Forskningsmiljøet ... -
Lipoprotein subfraction profiling in the search of new risk markers for myocardial infarction: The HUNT study
Sperstad, Sigri Bakken; Sæther, Julie Caroline; Klevjer, Marie; Giskeødegård, Guro F.; Bathen, Tone Frost; Røsbjørgen, Ragnhild; Dalen, Håvard; Bye, Anja (Peer reviewed; Journal article, 2023)Background Traditional biomarkers used to measure risk of myocardial infarction (MI) only explain a modest proportion of the incidence. Lipoprotein subfractions have the potential to improve risk prediction of MI. Aim We ... -
No Effect of Calanus Oil on Maximal Oxygen Uptake in Healthy Participants: A Randomized Controlled Study.
Tauschek, Lucas Christian; Røsbjørgen, Ragnhild; Dalen, Håvard; Larsen, Terje; Karlsen, Trine (Peer reviewed; Journal article, 2022)We aimed to investigate the long-term effect of daily Calanus oil supplementation on maximal oxygen uptake (VO2max) in healthy 30- to 50-year-old participants. The study was motivated by preclinical studies reporting ... -
Safety and efficacy of plasma transfusion from exercise - trained donors in patients with early Alzheimer’s disease: protocol for the ExPlas study

The Effect of Three Different Modes of Resistance Training on Biomarker Responses in Apparently Healthy Individuals
Schei-Andersen, Ane Jordan (Master thesis, 2022)Bakgrunn: Økninger i plasmakonsentrasjoner av de hjertespesifikke markørene troponin T og I er blitt observert i tilsynelatende friske individer etter intens utholdenhetstrening. Denne studien hadde som hensikt å undersøke ...
