Ventilatory, breathlessness, and leg fatigue data at rest and maximal exercise for each of the four cardiorespiratory exercise tests
| Test | Air with mouthpiece | Oxygen with mouthpiece | Air with mask | Oxygen with mask |
|---|---|---|---|---|
| Values are mean (SE). | ||||
| Vo2max, maximal oxygen consumption; Vco2max, maximal carbon dioxide production. | ||||
| Statistical analysis between groups was performed using ANOVA. All p values >0.05. | ||||
