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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles

    Författare :Yafeng Song; Per Stål; Sture Forsgren; Fawzi Kadi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triceps surae; overuse; contralateral; muscle; muscle fiber; MyHC; capillary; tachykinin; substance P; NK-1R; inflammation; anatomi; Human Anatomy;

    Sammanfattning : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. LÄS MER

  3. 3. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury

    Författare :Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; adrenaline;

    Sammanfattning : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. LÄS MER

  4. 4. Muscle Tenderness in Women

    Författare :Ann Persson; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Reliability.; Electronic algometer; Pain threshold; Pain measurement; Shoulder pain; Tenderness; Muscle; Nociception; Central processing; Physical medicine; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ;

    Sammanfattning : Longstanding pain experienced from the musculoskeletal system is reported by one third of the Swedish population. The underlying mechanisms are not known in the majority of cases. LÄS MER

  5. 5. Extra- and intrafusal muscle fibre type compositions of the human masseter at young age. : In perspective of growth and functional maturation of the jaw-face motor system

    Författare :Catharina Österlund; Per-Olof Eriksson; Lars-Eric Thornell; Per Stål; Malin Ernberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jaw; limb; human; muscle; morphology; fibre type; myosin heavy chain; muscle spindle; Morphology; Morfologi; anatomi; Human Anatomy;

    Sammanfattning : Muscles control body posture and movement by extrafusal and intrafusal (muscle spindle) fibres. The purpose of this thesis was to provide insight into the muscular basis for human jaw function at young age. LÄS MER
