  1. 11. 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. 12. Cardiac effects of prolonged exercise

    Författare :Anders Sahlén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angiotensin-Converting Enzyme; Exercise; Natriuretic Peptides; Troponin;

    Sammanfattning : Long-distance running is growing in popularity. While moderate exercise unquestionably gives major health benefits, the effects of extreme physical exhaustion on cardiac function have been studied less. It has previously been observed that elevated cardiac biomarkers may be observed after exercise, the significance of which is not known. LÄS MER

  4. 13. Physiology of Adventure Racing : with emphasis on circulatory response and cardiac fatigue

    Författare :C. Mikael Mattsson; Björn Ekblom; Keith P George; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiovascular drift; cardiac fatigue; adventure race; cardiac biomarkers; cardoac function; exercise echocardiography; Physiology; Fysiologi; Cardiology; Kardiologi; Sports; Idrott; Medicin Teknik; Medicine Technology;

    Sammanfattning : The overall aims of this thesis were to elucidate the circulatory responses to ultra-endurance exercise (Adventure Racing), and furthermore, to contribute to the clarification of the so called “exercise-induced cardiac fatigue” in relation to said exercise. An Adventure race (AR) varies in duration from six hours to over six days, in which the participants have to navigate through a number of check-points over a pre-set course, using a combination of three or more endurance/outdoor sports, e.

  5. 14. 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.

  7. 15. Cardiopulmonary Function in Healthy Individuals and in Patients After Hematopoietic Cell Transplantation

    Författare :Margareta Genberg; Andrei Malinovschi; Eva Nylander; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cell transplantation; echocardiography; cardiopulmonary execise testing; stress testing; onchology; childhood leukemia; healthy adults; breathing reserve; oxygen uptake; Clinical Physiology; Klinisk fysiologi;

    Sammanfattning : Background: The cardiopulmonary exercise test (CPET) is the gold standard of clinical exercise tests, combining conventional stress testing with measurement of oxygen uptake and carbon dioxide production. In order to interpret CPET findings, adequate reference values are needed. Currently, no Swedish reference values exist. LÄS MER
