Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in VO2 at the ventilatory anaerobic threshold (VAT) and oxygen uptake at peak exercise (VO2peak) after the 6-week prehabilitation program. The VAT will be measured at inclusion (3-9 weeks in advance of the operation) in a cardiopulmonary exercise test (CPET), and again after 3-9 weeks of training. This CPET will report the VAT in ml/kg/min. The difference between the first measurement and the second measurement will be the primary outcome. The oxygen uptake at peak exercise (VO2peak) will be compared as well. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Program feasibility (recruitment rate, adherence, completion rate, drop-out rate, attrition rate, and adverse events) using patient records at the end of the study 2. The (preliminary) effect of the program on other cardiopulmonary exercise testing (CPET) values at inclusion (3-9 weeks in advance of the operation) and again after 3-9 weeks of training 3. The effect of the program with the Luscii-app using a questionnaire at the first postoperative, outpatient control | — |
