  2. 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

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

    Abstract : 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. READ MORE

  4. 2. 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

  5. 3. Effects of Ageing and Physical Activity on Regulation of Muscle Contraction

    Author : Alexander Cristea; Lars Larsson; Anna-Stina Höglund; Ingrid Lundberg; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ageing; sarcopenia; sprint training; progressive resistance training; in vivo function; isokinetic dynamometer; in vitro function; single permeabilised fibre; myonuclear domain; confocal microscopy; Medicine; Medicin;

    Abstract : The aims of this study were to investigate the mechanisms underlying (1) the ageing-related motor handicap at the whole muscle, cellular, contractile protein and myonuclear levels; and (2) ageing-related differences in muscle adaptability.In vivo muscles function was studied in the knee extensors.

  6. 4. Molecular mechanisms mediating development of pulmonary cachexia in COPD

    Author : Vladimir Basic; Jorge Ruas; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; cachexia; atrophy; cigarette smoke; myogenesis; angiogenesis; Biomedicin; Biomedicine; Biokemi; Biochemistry;

    Abstract : Cigarette smoking (CS) represents the main causative agent underlying development and progress of COPD. Recently, involvement of CS in the pathogenesis of COPDassociated muscle abnormalities is becoming increasingly evident. Nevertheless, involved triggers and underlying mechanisms remain largely unknown. READ MORE

  7. 5. 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
