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

    Författare :Anna Maria Drake; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive brake; non-exhaust emissions; inertia brake dynamometer; airborne particles; PM10; PN; isokinetic sampling; Rebrake; volatiles; real driving cycle; car brake emission factors; running-in.; Bilbroms; icke-avgasemissioner; skivbromsdynamometer; luftburna partiklar; PM10; PN; isokinetisk provtagning; Rebrake; volatiler; verkliga körcykler; emissionsfaktorer; in-körning.; Machine Design; Maskinkonstruktion;

    Sammanfattning : Brake systems are used to safely stop vehicles. The brake pads are pressed against the brake disc, transforming the kinetic energy of the vehicle into heat to be dissipated. LÄS MER

  4. 8. Effects of Ageing and Physical Activity on Regulation of Muscle Contraction

    Författare :Alexander Cristea; Lars Larsson; Anna-Stina Höglund; Ingrid Lundberg; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 9. External Fixation of Femoral Fractures in Children : Clinical, radiological and functional outcome and cost analysis

    Författare :Hanne Hedin; Lars Engesäter; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Femoral fractures; children; external fixation; overgrowth; malunion; isokinetic muscle strength; cost analysis; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Orthopaedics; ortopedi;

    Sammanfattning : The overall aim of this thesis was to evaluate the outcome when treating children for displaced femoral fractures with external fixation.In a consecutive and prospective study during the period 1993-2000, 96 children aged 3-15 years with 98 displaced femoral fractures were treated with external fixation and early mobilisation. The mean age was 8. LÄS MER

  7. 10. Muscle function and physical activity in pre-pubertal school children

    Författare :Susanna Stenevi Lundgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; children; physical activity; exercise; isokinetic muscle strength; vertical jump height; normative; intervention; school transport; DXA; anthropometry; fat mass; lean mass; weight; height; body mass index; girls; boys; pre-pubertal;

    Sammanfattning : Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population.
