  3. 2. Mechanochemical Modeling of Smooth Muscle Activation

    Författare :Sae-Il Murtada; Gerhard A. Holzapfel; Robert McMeeking; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomechanics; Muscle contraction; Smooth muscle; Contractile unit; Filament overlap; Intracellular calcium; Carotid artery; Mathematical model;

    Sammanfattning : Smooth muscle has an important role in several physiological processes, where it regulates the wall tension and the size of hollow organs. In blood vessels, the contraction and relaxation of smooth muscle contribute to the mechanical stability of the vessel wall and determines the diameter. LÄS MER

  4. 3. Post activation potentiation : Modulating factors and mechanisms for muscle performance

    Författare :Paulo Gago; Ekblom Maria; Anton Arndt; Nicola Maffiuletti; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potentiation; twitch; triceps surae; knee angle; stiffnes; length changes; electromechanical delay; Medicin Teknik; Medicine Technology;

    Sammanfattning : Introduction: Acute enhancements of muscle contractile properties and performance subsequent to a maximal or near maximal conditioning contraction are often termed post activation potentiation (PAP). Although still controversial, PAP is commonly linked to enhancements in the myosin regulatory light chain phosphorylation, leading to improvements in the excitation–contraction coupling. LÄS MER

  5. 4. Voluntary activation of skeletal muscle in young and old women and men

    Författare :Michael Miller; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; pain measurement; electric stimulation; muscle; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ;

    Sammanfattning : The evaluation of skeletal muscle strength is an important part of the physiotherapist’s clinical examination in order to plan and execute appropriate interventions. This requires the objective assessment of muscle strength and the determination of the underlying factors of muscle weakness. LÄS MER

  7. 5. Tendon transfer mechanics and donor muscle properties : implications in surgical correction of upper limb muscle imbalance

    Författare :Eva Pontén; Bertil Romanus; Umeå universitet; []
    Nyckelord :laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; hand surgery;

    Sammanfattning : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. LÄS MER
