2. 16. Modelling of muscular force induced by non-isometric contraction

   Author : Natalia Kosterina; Anders Eriksson; Michael Günther; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skeletal muscle; Muscular force; Concentric contractions; Eccentric con- tractions; History effect; Force modification; Muscle model; Musculoskeletal model;

   Abstract : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. READ MORE

4. 17. Magnetic resonance imaging in chronic Achilles tendinopathy

   Author : Adel Shalabi; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Achilles tendon; tendinopathy; MRI; gadolinium contrast; 3-D seed growing; surgery; eccentric training.;

   Abstract : The main objective of this thesis was to evaluate and monitor the morphological response following treatment interventions in patients with chronic Achilles tendinopathy by using different MRI-techniques. For this purpose. READ MORE

5. 18. Velocity controlled dynamometry and gait analysis : development of methods and applications

   Author : Lennart Gransberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Dynamometry; torque; measurement error; overshoot; isokinetic; concentric; eccentric; gait analysis; three-dimensional; electrogoniometer; electromagnetic tracking;

   Abstract : The isokinetic systems developed in the present study can measure torque in maximal voluntary and passive movements. The torque recordings may be combined with surface EMG recordings from pairs of antagonistic muscles involved in the movement. Healthy subjects and patients with spastic paresis have been examined.

6. 19. Changes in mitogen-activated protein kinase phosphorylation and inorganic phosphate induced by skeletal muscle contraction

   Author : Charlott Wretman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Skeletal muscle; MAP kinase; signal transduction; contraction; acute exercise; exercise intensity; fibre-type; concentric; ROS; eccentric.;

   Abstract : Skeletal muscles adjust to the level of contractile activity by different biochemical alterations. Contraction is a multifactorial stimulus with short-term metabolic effects and long-term responses due to changes in protein synthesis. READ MORE

7. 20. Immunological changes in human blood and skeletal muscle in response to physical exercise

   Author : Christer Malm; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Eccentric exercise; soccer; football; adaptation; immune system; muscle; inflammation; damage; leukocytes; growth factors; cytokines; adhesion; signaling; hormones.;

   Abstract : Physical exercise is essential for maintaining normal function of skeletal muscle. Muscle tissue also has a remarkable capacity for adaptation to changes in physical demand. In fact, without stimulation from physical activity, muscle tissue will atrophy. READ MORE
