  1. 1. 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

  3. 2. Adaptability of skeletal muscle to hormone treatment in relation to gender and aging

    Författare :Fushun Yu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :skinned muscle fiber; gender; aging; steroid hormone; V0 electrophoresis; MyHC; MyLC; enzymehistochemistry; hyperthyroid rat; thyroid hormone receptor TR deficient TR[alpha]1 - -; TR[beta]- -; and TR[alpha]1- -[beta]- - mice;

    Sammanfattning : The aims of this study were to investigate the expression of myosin isoforms, muscle contractility at the cell level, and changes in these parameters in response to altered hormonal status in aging male and female rodents. In addition, by using mice lacking thyroid hormone receptors (TR[alpha]1 or TR[beta] or TR[alpha]1/[beta]) we tried to improve our understanding of the mechanisms by which thyroid hormone regulates the expression of specific MyHC isoforms via these different nuclear receptors.

  4. 3. Re-evaluation of exercise-induced muscle soreness : an immunohistochemical and ultrastructural study

    Författare :Ji-Guo Yu; Bengt Saltin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anatomy; Anatomi; Anatomy; Anatomi;

    Sammanfattning : Delayed onset muscle soreness (DOMS) is a familiar experience for the elite and novice athletes. Symptoms can range from muscle tenderness to severe deliberating pain. It is generally believed that eccentric contractions produce higher tension on muscle fibres and connective tissues than concentric and isometric contractions. LÄS MER
