  1. 1. Skeletal muscle fiber types in man : With special reference to anabolic signaling and mitochondrial bioenergetics

    Författare :Sebastian Edman; William Apro; Filip J Larsen; Abram Katz; Leigh Breen; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mTORC1; THRIFTY; fiber type identification; muscle growth; aging; sarcopenia; mitochondrial function; oxphos; metabolism; Medicin Teknik; Medicine Technology;

    Sammanfattning : Human skeletal muscle consists of a mixture of slow-twitch (type I) and fast-twitch (type II) fibers. The type I fibers are endurance-oriented, with a metabolic system and infrastructure that supports aerobic metabolism. LÄS MER

  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. 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

  5. 4. Muscle Morphology and the Insulin Resistance Syndrome : A Population-Based Study of 70 Year-Old-Men in Uppsala

    Författare :Anu Hedman; Stevo Julius; Uppsala universitet; []
    Nyckelord :Medical sciences; Muscle morphology; fiber distribution; capillary density; insulin resistance syndrome; physical activity; hypertension; insulin-mediated blood flow; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Skeletal muscle accounts for the largest part of insulin-mediated glucose uptake. Insulin resistance (IR) is the main component of insulin resistance syndrome (IRS) and is an essential cause of a number of cardiovascular risk factors. LÄS MER

  7. 5. Strenght training and anabolic steroids : a comparative study of the trapezius, a shoulder muscle and the vastus lateralis, a thigh muscle, of strength trained athletes

    Författare :Anders Eriksson; Bengt Saltin; Umeå universitet; []
    Nyckelord :strength training; anabolic steroids; vastus lateralis; trapezius; enzymehistochemistry; immunohistochemistry; muscle fiber; myonuclei; satellite cell; anatomi; Human Anatomy;

    Sammanfattning : Strength training is widely used to increase performance in sports with high physical demands. The use of drugs such as anabolic steroids among athletes is a wellknown phenomenon, and the effects of these drugs on physical performance documented. LÄS MER
