2. 1. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

   Author : Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

   Abstract : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

4. 2. Structure and function of the cytoskeleton in cardiac and skeletal muscle

   Author : Johanna Balogh; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP-receptor; Cardiovascular system; Kardiovaskulära systemet; cardiomyopathy; transgenic mice; skeletal muscle; heart; muscle contraction; cytoskeleton; desmin;

   Abstract : We have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. READ MORE

5. 3. Intracellular mechanisms of skeletal muscle fatigue : role of creatine kinase

   Author : Anders Dahlstedt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Skeletal muscle fatigue; creatine kinase; inorganic phosphate; adenosine diphosphate;

   Abstract : During intense physical activity the maximal power output of skeletal muscles is reduced, a condition described as muscle fatigue. The cause of impaired muscle function seen in fatigue is multifactorial. READ MORE

6. 4. Structure and function of the ankle dorsiflexor muscles in young healthy men and women

   Author : Anna Maria Drake; Människan i rörelse: hälsa och rehabilitering; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Physical medicine; reproducibility of results; muscle fibres; magnetic resonance imaging; isokinetic strength; skeletal muscle; Ankle joint;

   Abstract : The overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. READ MORE

7. 5. Leisure and muscular performance in health and disease : a study of 40-64-year-old northern Swedes

   Author : Björn Gerdle; Kerstin Sjögren; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Leisure; health; skeletal muscle; isokinetics; electromyography; plantar flexion; muscular fatigue;

   Abstract : Categories and frequencies of leisureactivities employed by 156 randomly selected males and females aged 40-44, 50-54, 60-64 were investigated by structured interviews and were related to leisuresatisfaction, to experienced health and socio-economic status. In equal numbers (15) of males and females from each group and in 24 males (60 +_6 years) with intermittent claudication (Cl) isokinetic plantar flexion performance was investigated with registrations of peak torque (PT), contractional work (CW), active range-of-motion (RoM) and integrated electromyograms from all threee triceps surae heads.
