  1. 1. Exercise-induced muscle soreness : a qualitative and quantitative study of human muscle morphology and function

    Författare :Jan Fridén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; exercise; exertion; eccentric contractions; muscles; muscle strength; muscle soreness; fibre types; myofibrils; muscle proteins; histocy to chemistry; ultrastructure; stereology;

    Sammanfattning : Exercise-induced muscle soreness is characterized by stiffness, tenderness and pain during active movements and weakness of the affected musculature the days after unusually or particularly heavy work. The most pronounced subjective symptoms do not arise immediately but rather between a couple of hours to some days after the exercise (a delayed-onset of muscle soreness), the intensity of pain is greatest about 48 hours after the work.

  3. 2. Effects of PGC1a-induced exercise adaptations in muscle on plasticity and recovery mechanisms in the CNS

    Författare :Lars O Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle; brain; exercise; transgenic; PGC-1α; FNDC5; irisin;

    Sammanfattning : In this thesis, we sought to determine if muscle-derived exercise-induced signaling via PGC-1α muscle activation influences neuroplasticity under physiological or pathophysiological conditions. For this purpose, transgenic mice with muscle-specific overexpression of PGC-1α that display an endurance exercise muscle phenotype were evaluated in models of cranial irradiation and photothrombotic stroke, as well as in aging and in a voluntary running paradigm.

  4. 3. Influence of Oxidative Stress on Muscle and Bone

    Författare :Bengt Östman; Karl Michaëlsson; Lars Nordsletten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone mineral density; coenzyme Q10; exercise; ischaemia; isprostanes; muscle; oxidative stress; oxygen radicals; reperfusion; tocopherol; Orthopaedics; Ortopedi; ortopedi; Orthopaedics;

    Sammanfattning : Reactive oxygen species (ROS) induce oxidative stress and although are primarily recognized for playing a deleterious biological role, they can be beneficial to cell systems. ROS are extremely short-lived and normally tightly regulated by antioxidant defence systems. LÄS MER

  7. 5. Sceletal muscle characteristics and physical activity patterns in COPD

    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
