  2. 1. Myonuclear Organization and Regulation of Muscle Contraction in Single Muscle Fibres : Effects of Ageing, Gender, Species, Endocrine Factors and Muscle Size

    Author : Rizwan Qaisar; Lars Larsson; Jo Bruusgaard; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single muscle cells; muscle nuclei; specific force; species; hypertrophy; mammals; ageing; gender; Physiology; Fysiologi;

    Abstract : The skeletal muscle fibre is a syncitium where each myonucleus regulates the gene products in a finite volume of cytoplasm i.e., the myonuclear domain (MND). READ MORE

  4. 2. Modelling of muscular force induced by non-isometric contraction

    Author : Natalia Kosterina; Anders Eriksson; Michael Günther; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skeletal muscle; Muscular force; Concentric contractions; Eccentric con- tractions; History effect; Force modification; Muscle model; Musculoskeletal model;

    Abstract : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. READ MORE

  5. 3. Vibration-induced muscle injury in the hand - experimental and clinical studies

    Author : Lars Necking; Malmö Handkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; muscle morphometry; intrinsic hand muscle; muscle strength; muscle injury; hand weakness; Vibration exposure; hand-arm vibration syndrome; orthopaedics; traumatology; Kirurgi; ortopedi;

    Abstract : Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. READ MORE

  6. 4. Human muscle spindles : complex morphology and structural organisation

    Author : Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
    Keywords : human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

    Abstract : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. READ MORE

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

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

    Abstract : 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. READ MORE
