  1. 1. Aspects of regular long-term endurance exercise in adolescents, with focus on cardiac size and function, hormones, and the immune system

    Författare :Louise Rundqvist; Maria Faresjö; Peter Blomstrand; Katarina Steding-Ehrenborg; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; endurance-trained; cardiac dimension; cardiac systolic function; cardiac diastolic function; growth hormone; immune response; echocardiography; biomarkers; cytokines; chemokines; insulin-like growth factor 1; type 1 diabetes-related autoantigen; proinsulin;

    Sammanfattning : The long-term effects of starting high-intensity training at younger ages are largely unknown. The present studies focused on adolescents who had performed regular endurance exercise for several years at an elite level and compared those subjects with a control group of adolescents of similar age and sex who had not engaged in regular exercise.

  3. 2. Pump Physiology in the Remodeled Heart

    Författare :Björn Östenson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac magnetic resonance; cardiac remodeling; exercise imaging; exercise physiology; regional contributions to stroke volume; feature-tracking strain; atrioventricular plane displacement; atrioventricular coupling; ventricular-arterial coupling; clinical physiology;

    Sammanfattning : This thesis aimed to increase the understanding of pump physiology in the remodeled heart compared to normal pump physiology.Study I was a cross-sectional observatory study investigating the regional contributions to stroke volume in patients with heart failure prior to cardiac resynchronization therapy (CRT) and tested the hypothesis that this characterization of pumping could predict CRT response.

  4. 3. Estrogen receptors in skeletal muscle : expression and activation

    Författare :Anna Wiik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : There are two estrogen receptors (ERs), ERalpha and ERbeta, which are ligand activated transcription factors. Estrogen, which exerts its effect via ERs, is not only a female reproductive hormone, but acts almost ubiquitously in the human body and is involved in physiological and pathological states in both males and females.

  5. 4. Fatty Acid Composition in Skeletal Muscle : Influence of Physical Activity and Dietary Fat Quality

    Författare :Agneta Andersson; Len Storlien; Uppsala universitet; []
    Nyckelord :Medical sciences; Skeletal muscle; phospholipids; triglycerides; fatty acids; physical activity; lipid peroxidation; dietary fat quality; n-3 polyunsaturated fatty acids; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Insulin sensitivity is related to the fatty acid profile of skeletal muscle. The aim of this thesis was to investigate whether physical activity and dietary fat quality, independent of each other, influence the fatty acid composition of the skeletal muscle lipids. LÄS MER

  7. 5. Left Ventricular Dynamics During Exercise in Endurance Athletes

    Författare :Milena Sundstedt; Tommy Jonason; Egil Henriksen; Eva Nylander; Uppsala universitet; []
    Nyckelord :Physiology; athletes; exercise; left ventricular dynamics; stroke volume; mitral annular motion; Fysiologi;

    Sammanfattning : Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes. LÄS MER
