Published: Patient-reported questionnaires to preoperatively identify high-risk surgical patients
Purpose: Low cardiorespiratory fitness (CRF) increases the risk of postoperative morbidity and mortality following major surgery. Assessing CRF preoperatively, by measuring peak oxygen uptake (VO2peak) during cardiopulmonary exercise testing (CPET), is...

Published: Test-retest reliability of the FitMáx©-questionnaire in a clinical and healthy population
Purpose: The FitMáx© was developed as a questionnaire-based instrument to estimate Cardiorespiratory Fitness (CRF) expressed as oxygen uptake at peak exercise (VO2peak). Test-retest reliability is a clinometric measurement property, which defines...

Published: Evaluation of two self-reported questionnaires for assessment of peak exercise capacity in patients with chronic heart failure
Background: Peak oxygen uptake (VO2peak), assessed by maximal cardiopulmonary exercise testing (CPET), is a powerful predictor of cardiovascular morbidity and mortality. In clinical practice, the use of CPET is often not feasible or desirable in...
