Submitted articles:

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 [Submitted]
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

Currently under investigation:
