1. 16. Design and Control Parameter Optimization of Soft Ankle Exoskeleton for People with Dropfoot and Excessive Inversion

   Författare :Xiaochen Zhang; Elena Gutierrez-Farewik; Ruoli Wang; Susanne Palmcrantz; Shaoping Bai; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assistive device; Biomechanics; Gait impairment; Movement augmentation; Assistiv enhet; Biomekanik; Gångnedsättning; Rörelseförstärkning; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Wearable robotics and exoskeletons have been explored for their efficacy in physical rehabilitation and for assistance in daily activities for people with motor disorders. The overall objective of this thesis is to design a powered soft exoskeleton for people with dropfoot and excessive inversion, commonly after a stroke, and to optimize the control parameters for each individual while considering different dimensions.

3. 17. Early specialising aesthetic performers : An investigation of conceptualisation, motivation, and context

   Författare :Charlotte Downing; Sanna Nordin-Bates; Karin Redelius; Joe Baker; Gymnastik- och idrottshögskolan; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Samhällsvetenskap Humaniora; Social Sciences Humanities;

   Sammanfattning : This doctoral research project is situated within the wider debate of talent development in so-called early sports, where early specialisation is often normalised. The overarching aim is to investigate early specialisation within the context of Swedish aesthetic activities. LÄS MER

4. 18. Skeletal muscle fiber types in man : With special reference to anabolic signaling and mitochondrial bioenergetics

   Författare :Sebastian Edman; William Apro; Filip J Larsen; Abram Katz; Leigh Breen; Gymnastik- och idrottshögskolan; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mTORC1; THRIFTY; fiber type identification; muscle growth; aging; sarcopenia; mitochondrial function; oxphos; metabolism; Medicin Teknik; Medicine Technology;

   Sammanfattning : Human skeletal muscle consists of a mixture of slow-twitch (type I) and fast-twitch (type II) fibers. The type I fibers are endurance-oriented, with a metabolic system and infrastructure that supports aerobic metabolism. LÄS MER

5. 19. Exercising on the edge: mitochondrial and metabolic responses to intense training

   Författare :Mikael Flockhart; Filip J Larsen; Eva Blomstrand; Nikolai Baastrup Nordsborg; Gymnastik- och idrottshögskolan; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; training; mitochondria; performance; glucose tolerance; proteins; oxygen uptake; metabolism; cycling; Medicin Teknik; Medicine Technology;

   Sammanfattning : Exercise and exercise training induces several physiological adaptations that increase the oxidative capacity of the muscles and improve glucose regulation. While the positive metabolic adaptations and effects on glucose regulation after exercise and exercise training have been extensively studied, negative outcomes have not. LÄS MER

7. 20. Bilateral kinetic, kinematic, neuromechanical, and muscle-tendon properties of habitual runners

   Författare :Tiago Canal Jacques; Anton Arndt; Rodrigo Bini; John Rasmussen; Gymnastik- och idrottshögskolan; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

   Sammanfattning : Achilles tendon overuse-related injuries are a frequent problem to habitual runners. Such injuries occur more often unilaterally and its etiology is associated to overloading of the tendon tissue. Inter-limb differences during running are a possible cause for overload due to eventual differences in the mechanical loading provided to each limb. LÄS MER
