- Primary Outcome Measures
Name Time Method <p>Various parameters of oxidative stress will be analyzed in blood, urine as well<br /><br>in exhaled breath. These pulmonary and systemic oxidative stress markers will<br /><br>be compared between COPD patients and healthy controls at rest and during<br /><br>exercise. Mechanical efficiency and endurance of the quadriceps femoris muscle<br /><br>in COPD versus healthy controls will be tested with the single-leg ergometer<br /><br>test. </p><br>
- Secondary Outcome Measures
Name Time Method <p>To investigate possible determinants of quadriceps femoris muscle endurance<br /><br>(impairment of airway obstruction, exercise capacity, daily activity level, leg<br /><br>muscle strength, total body and leg FFM).</p><br>
