  1. 1. Exercise-induced muscle soreness : a qualitative and quantitative study of human muscle morphology and function

    Författare :Jan Fridén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; exercise; exertion; eccentric contractions; muscles; muscle strength; muscle soreness; fibre types; myofibrils; muscle proteins; histocy to chemistry; ultrastructure; stereology;

    Sammanfattning : Exercise-induced muscle soreness is characterized by stiffness, tenderness and pain during active movements and weakness of the affected musculature the days after unusually or particularly heavy work. The most pronounced subjective symptoms do not arise immediately but rather between a couple of hours to some days after the exercise (a delayed-onset of muscle soreness), the intensity of pain is greatest about 48 hours after the work.

  3. 2. 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

  4. 3. Myofibrillens finstruktur i tvärstrimmig skelettmuskulatur

    Författare :Anne-Christine Edman; Michael Sjöström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle; muscle fibre; fibre type; myofilament; A-band; M-band; cryo-ultramicrotomy; electron microscopy; image analysis;

    Sammanfattning : The detailed structure of the myofibrillar material in fibres from different muscles has been studied. Specimens have been obtained from human muscles and from different muscles frequently examined in experimental studies. Both light- and electron microscopical techniques have been used. LÄS MER

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

    Författare :Lars Necking; Malmö Handkirurgi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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). LÄS MER
