Popis: Aims: This study investigated whether acute hyperoxia improves electrical muscle activity in active chronic obstructive pulmonary disease (COPD) patients with mild hypoxemia (rest PaO2 = 9.1 ± 0.4 kPa). Methods: Two identical incremental exercise tests were performed by nine patients while breathing either air or 30% oxygen. Pulmonary gas exchanges, venous concentrations of lactate and pyruvate, and the electromyographic signal of the quadriceps muscle (vastus lateralis and vastus medialis) were sampled each minute. Results: Peak working capacity increased significantly in hyperoxia (94.4 ± 5.2W) compared with normoxia (85.4 ± 5.8W, P
