Criteria for training group (TG) allocation based on the algorithm for prognostic and diagnostic stratification criteria for patients with chronic lung and heart disease described in the study by Guazzi et al [28]a.
| Group | VO2peakb (mL/min/kg) | PPOc (W/kg of body weight) | VE/VCO2d slope (full slope) |
| TG 1 | <16 | <1 | >45 |
| TG 2 | 16-20 | 1-1.5 | 30-45 |
| TG 3 | >20 | >1.5 | <30 |
aIf 2 out of 3 variables correspond to one of the TGs, the study participant is assigned to that group. If all 3 variables are aligned with different groups, the group allocation is discussed individually with the study physician.
bVO2peak: highest oxygen uptake rate achieved during the cardiopulmonary exercise test.
cPPO: peak power output.
dVE/VCO2: minute ventilation/carbon dioxide production.
