title: Selecting the increment size for a maximal incremental cycle test in patients with COPD.
abstract: Currently, to our knowledge, there are no chronic obstructive pulmonary disease (COPD)-specific formulas to predict the maximum workload of an incremental cycle ergometer test. The aim of the study was to investigate different prediction models including COPD-specific variables of maximum workload in 113 mild to very severe COPD patients. This study shows that simple measures like forced expiratory volume in 1 s, chair-stand test and modified Medical Research Council dyspnoea score may improve the accuracy of the predicted maximum workload in COPD patients.
