Published: Estimating VO2peak in 18-90 Year-Old Adults: Development and Validation of the FitMáx©-Questionnaire
Purpose: Cardiorespiratory fitness (CRF) plays an essential role in health outcomes and quality of life. However, it is often not assessed nor estimated. Objective CRF assessment is costly, labour intensive and not widely available. Patient-reported...

Published: Monitoring aerobic capacity in cancer survivors using self-reported questionnaires: criterion validity and responsiveness
Background: Evaluating the criterion validity and responsiveness of the self-reported FitMáx©-questionnaire, Duke Activity Status Index (DASI) and Veterans Specific Activity Questionnaire (VSAQ) to monitor aerobic capacity in cancer survivors. Methods:...

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...

Submitted: Assessing Cardiorespiratory Fitness in Clinical Rehabilitation: Validity of Field Exercise Tests and Patient-Reported Questionnaires
Objective: This cross sectional study evaluated criterion and construct validity of field exercise tests and patient-reported questionnaires to estimate cardiorespiratory fitness (CRF) compared with cardiopulmonary exercise testing (CPET). It also...
