    Abstract : 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.

  2. 2. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle

    University dissertation from Uppsala : Acta Universtatis Upsaliensis

    Author : Erik Olsson; Lennart Melin; Ulf Lundberg; [2010]
    Keywords : heart rate variability; autonomic nervous system; vagal tone; allostatic load; stress; fatigue; anxiety; depression; continuous performance; attention; cardiovascular risk; lifestyle; physical activity;

    Abstract : Heart rate varies constantly as a consequence of activity in the sympathetic and parasympathetic autonomic nervous systems (SNS and PNS). In short-term recordings, heart rate variability (HRV) is mostly related to the inhibitory activity of the vagal nerves, which are part of the PNS. READ MORE

  3. 3. Evaluation of various strategies to improve outcome after out-of-hospital cardiac arrest with particular focus on mechanical chest compressions

    University dissertation from Göteborg : University of Gothenburg

    Author : Christer Axelsson; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; out-of-hospital cardiac arrest; mechanical chest compressions; end tidal carbon dioxide; passive leg raising; dispatch code; randomised clinical trial;

    Abstract : Cardiopulmonary resuscitation (CPR) skills vary among health care professionals. A previous study revealed that chest compressions were only performed half the time in out-of-hospital cardiac arrest (OHCA). Field conditions and fatigue could be possible explanations. READ MORE

  4. 4. Cardiac effects of prolonged exercise

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine

    Author : Anders Sahlén; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiotensin-Converting Enzyme; Exercise; Natriuretic Peptides; Troponin;

    Abstract : 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. READ MORE
