  1. Estimating VO2peak in 18–90 Year-Old Adults: Development and Validation of the FitMáx©-Questionnaire (Dove Press: International Journal of General Medicine) https://doi.org/10.2147/IJGM.S355589

Current research:

  1. Test-Retest Reliability of the FitMáx© |
    In a wide population (>200 patients) the test-retest reliability is assessed by filling out the questionnaire twice in a time window of 2-3 weeks. FiMáx© is compared to the Duke Activity Status Index (DASI) and Veterans Specific Activity Questionnaire (VSAQ)
  2. Preoperative risk assessment with FitMáx© |
    Positioning FitMáx© in the clinical context of prehabilitation as a tool to assess low exercise capacity with its increased risk of complications during and after surgery
  3. Responsiveness of the FitMáx© | 
    Accuracy of FitMáx© to detect changes in cardiorespiratory fitness related to training
  4. Comparing the reliability of FitMáx© compared to other exercise test | 
    FitMáx© is compared to steep ramp test and 6 minute walk test with cardiopulmonary exercise testing as the gold standard
  5. Reliability to asses the phyisical fitness in COVID-19 survivors |
    The FitMáx© is used to estimate the physical fitness with cardio pulmonary exercise test as the gold standard

Future research:

  1. Recall bias of the FitMáx© |
    Reliability for estimating cardiorespiratory fitness in retrospective situations with the FitMáx©


Current research is conducted following the international COSMIN criteria for development and optimising questionnaires.
