  2. 1. Muscle Thixotropy : Implications for Human Motor Control

    Author : Hans Axelson; Karl-Erik Hagbarth; Mikael Elam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; Neurology; Neurologi;

    Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE

  4. 2. Sceletal muscle characteristics and physical activity patterns in COPD

    Author : Gabriella Eliason; Karin Phiel Aulin; Lundberg Ingrid; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; muscle morphology; muscle fibre distribution; muscle capillarization; physical activity; von Hippel-Lindau protein; exercise capacity; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Sports; Idrott; Idrottsvetenskap; Sports Science;

    Abstract : Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Besides abnormities within the respiratory system COPD is also associated with effects outside the lungs, so called systemic effects. READ MORE

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

    Author : Agneta Andersson; Len Storlien; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Repetitive and monotonous work among women : Psychophysiological and subjective stress reactions, muscle activity and neck and shoulder pain

    Author : Dag Rissén; Bo Melin; Ulf Lundberg; Anders Kjellberg; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Repetitive and monotonous work; women; psychophysiological stress reactions; subjective stress reactions; muscle activity; trapezius muscle; neck and shoulder pain; job rotation; Psychology; Psykologi;

    Abstract : Repetitive and monotonous work is frequently associated with neck and shoulder pain and negative psychosocial factors inducing stress reactions. The present thesis concerns the relations between psychophysiological and subjective stress reactions, muscle activity measured by surface electromyography (SEMG) in the trapezius muscle, and neck and shoulder pain in women performing repetitive and monotonous work.

  7. 5. Physical Activity and Cardiovascular Disease

    Author : Kasper Andersen; Johan Sundström; Claes Held; Frieder Braunschweig; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; epidemiology; cohort study; heart failure; cardiovascular disease; arrhythmias; atrial fibrillation; bradyarrhythmias; sudden cardiac death; heart failure; stroke; ischemic heart disease; cardiovascular death; maximal exercise capacity; muscle strength; skeletal muscle morphology; Kardiologi; Cardiology; Epidemiology; Epidemiologi;

    Abstract : The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. READ MORE
