  1. 16. Muscle mitochondria in sepsis

    Författare :Katarina Fredriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Patients treated in the intensive care unit (ICU) for sepsis induced multiple organ failure often suffer from skeletal muscle fatigue after ICU discharge. Since mitochondria are the main determinants of muscle fatigability, their function in muscle of these patients was the theme of this thesis. LÄS MER

  3. 17. Intracellular mechanisms of skeletal muscle fatigue : role of creatine kinase

    Författare :Anders Dahlstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Skeletal muscle fatigue; creatine kinase; inorganic phosphate; adenosine diphosphate;

    Sammanfattning : During intense physical activity the maximal power output of skeletal muscles is reduced, a condition described as muscle fatigue. The cause of impaired muscle function seen in fatigue is multifactorial. LÄS MER

  4. 18. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Författare :Amitava Halder; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Sammanfattning : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

  5. 19. Cellular mechanisms of human muscle fatigue and disease-related loss of muscle function

    Författare :Karl Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A loss of skeletal muscle function and mass is a hallmark of several diseases resulting in a dismal life quality and poor prognosis. Impaired intracellular Ca2+- handling has been proposed as an underlying cause of these manifestations. LÄS MER

  7. 20. 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.
