   Författare :Gabriella Eliason; Karin Phiel Aulin; Lundberg Ingrid; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; muscle morphology; muscle fibre distribution; muscle capillarization; physical activity; von Hippel-Lindau protein; exercise capacity; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Sports; Idrott; Idrottsvetenskap; Sports Science;

   Sammanfattning : Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Besides abnormities within the respiratory system COPD is also associated with effects outside the lungs, so called systemic effects. LÄS MER

3. 2. 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

4. 3. The muscle cytoskeleton of mice and men : Structural remodelling in desmin myopathies

   Författare :Lena Carlsson; Lars-Eric Thornell; Anders Arnér; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; desmin; nestin; synemin; paranemin; plectin; αB-crystallin; skeletal muscle; heart muscle; myotendinous junction; motor endplate; costamere; anatomi; Human Anatomy;

   Sammanfattning : The muscle fibre cytoskeleton of skeletal and heart muscle cells is composed mainly of intermediate filaments (IFs), that surround the myofibrils and connect the peripheral myofibrils with the sarcolemma and the nuclear membrane. Desmin is the first muscle specific IF protein to be produced in developing muscles and is the main IF protein in mature muscles. LÄS MER

5. 4. Distribution, total number and size of different types of fibres in male and female skeletal muscles : an enzyme histochemical study of whole muscle cross-sections

   Författare :Karin Henriksson-Larsén; Umeå universitet; []
   Nyckelord :Muscle biopsy; human; enzyme histochemistry;

   Sammanfattning : In order to investigate the total number, relative proportions, size variations and distribution patterns of fibres of different types in human skeletal muscles, a technique was developed which allows whole muscle cross-sections to be collected and stained enzyme histochemically. Necropsy material was obtained from m. tibialis anterior and m. LÄS MER

7. 5. The dancer : physical effort, muscle fibre types, and energy intake and expenditure

   Författare :Monica Dahlström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Children; dance; diet; exercise; exertion; female; fitness; muscle.;

   Sammanfattning : The aims of this thesis were: - to estimate aerobic fitness in dancers and analyse possible changes during a three-year dance course and after a detraining period; to compare different dance styles with regard to the duration of single exercises and the following rest periods; - to estimate the physical effort in dancers during training sessions in different styles of dance; - to compare the physical effort during training sessions in dance teachers with that of dance students; - to illuminate whether a deviating muscle fibre type distribution, if any, were training-induced or the result of selection of individuals with suitable fibre characteristics, muscle fibre type distribution was compared between children, at the very beginning of their professional dance training and dancers, who had performed professional dance training for 10 years. Moreover, muscle fibre type composition was analysed in dancers after detraining. LÄS MER
