1. 1. Structure and function of the ankle dorsiflexor muscles in young healthy men and women

   Författare :Anna Maria Drake; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Physical medicine; reproducibility of results; muscle fibres; magnetic resonance imaging; isokinetic strength; skeletal muscle; Ankle joint;

   Sammanfattning : The overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. LÄS MER

3. 2. Skeletal muscle in Restless legs syndrome (RLS) and Obstructive sleep apnoea syndrome (OSAS)

   Författare :Britta Wåhlin Larsson; Karin Piehl-Aulin; Fawzi Kadi; Jan Ulfberg; Carl-Johan Sundberg; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RLS; OSAS; aerobic capacity; skeletal muscle fibers; capillary; VEGF; Physiology; Fysiologi; Idrottsvetenskap; Sports Science;

   Sammanfattning : Restless legs syndrome (RLS) and Obstructive sleep apnoea syndrome (OSAS) are two sleep disorders that affect daily life with symptoms such as sleepiness and fatigue. It was therefore hypothesised that the skeletal muscle could be affected as symptoms from skeletal muscle are common. LÄS MER

4. 3. Distribution, total number and size of different types of fibres in male and female skeletal muscles : an enzyme histochemical study of whole muscle cross-sections

   Författare :Karin Henriksson-Larsén; Umeå universitet; []
   Nyckelord :Muscle biopsy; human; enzyme histochemistry;

   Sammanfattning : In order to investigate the total number, relative proportions, size variations and distribution patterns of fibres of different types in human skeletal muscles, a technique was developed which allows whole muscle cross-sections to be collected and stained enzyme histochemically. Necropsy material was obtained from m. tibialis anterior and m. LÄS MER

5. 4. Effects of unloading on skeletal muscle mass and function in man

   Författare :Hans Berg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Atrophy; bedrest; concentric and isometric and eccentric muscle actions; disuse; electromyography; fatigue; fiber types and size; humans; inactivity; maximal voluntary force; recovery; skeletal muscle cross-sectional area; strength; suspension; tomog;

   Sammanfattning : An experimental human model of skeletal muscle unloading of one lower limb and confined bedrest were employed to quantitate the adaptive responses to 10 days, 4 or 6 wk of unloading in healthy humans on quadricep skeletal muscle mass and function. Muscle cross-sectional area (CSA) was assessed using tomographic imaging (CT, MRI). LÄS MER

7. 5. Response of human skeletal muscle to chronic and acute exercise and ischemia : muscle dimensions, tissue water and blood flow as measured by magnetic resonance imaging and comparative methods

   Författare :Anders T Nygren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Bloodflow; cross-sectional area; exercise; fiber area; Gd-DTPA; glycogen; human; hypotrophy; intermittent claudication; ischemia; magnetic resonance imaging; metabolism; perfusion; reflex sympathetic activity skeletal muscle; training; transverse relaxation; ultrasonography.;

   Sammanfattning : The aim of this study was to investigate the response of human skeletal muscle to exercise, training and ischemi and to evaluate if magnetic resonance imaging (MRI) could be used to measure regional muscle cross-sectional area, muscle perfusion and detect muscle ischemia in patients with intermittent claudication. For this purpose studies were performed on 29 healthy young volunteers and 7 patients with intermittent claudication. LÄS MER
