  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. 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

  4. 3. 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

  5. 4. Lysophosphatidic acid : Physiological effects and structure-activity relationships

    Författare :Ulrika K. Nilsson; Samuel Svensson; Karin E. Bornfeldt; Linköpings universitet; []
    Nyckelord :Lysophospholipids pharmacology; physiology; structure-activity relationship; muscle; smooth; drug effects; myometrium; norepinephrine; epinephrine; signal transduction; MEDICINE; MEDICIN;

    Sammanfattning : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. LÄS MER

  7. 5. Human muscle spindles : complex morphology and structural organisation

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

    Sammanfattning : 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. LÄS MER
