COPD patients have a reduced exercise tolerance due to a ventilatory limitation.
Reduced exercise tolerance is one of the hallmarks of COPD and The principal causes for exercise intolerance are ventilatory limitation leading to deconditioning and inactivity. However the weak correlation between exercise capacity and FEV1 implies that other factors than reduced pulmonary function contributes to this impairment . Several studies have found changes in skeletal muscle, with fibre shift, increased oxidative stress, increased inflammatory cytokines and impaired mitochondrial function, suggesting a lower limb dysfunction
Numerous exercise studies in COPD patients have shown physiological and physiological benefits of training and endurance training is now regarded as an important part in pulmonary rehabilitation.
We therefore want conduct a study to investigate training effects in patients with moderate to severe COPD with special focus on skeletal muscle.
The COPD patients will therefore perform high intensity aerobic interval knee-extensor exercise training 3 days/week for six weeks . At baseline and followup, muscle oxygen consumption and mitochondrial respiration will be measured.

COPD (chronic obstructive pulmonary disease)
COPD (chronic obstructive pulmonary disease) is used for a number of conditions including chronic bronchitis and emphysema, which all lead to the airways in the lungs becoming damaged and thus narrower, making inhalation and exhalation harder...
