01 · Higher Inspired Oxygen. Breathing oxygen-enriched air raises inspired oxygen partial pressure. The effect on blood and tissue oxygen availability depends on concentration, workload and individual physiology.
02 · Active Exercise. You still pedal, produce force and elevate cardiovascular demand. Oxygen does not replace the work; it changes the conditions under which that work is performed.
03 · Individualized Workload. Intensity is selected from your baseline, exercise history and goals. Progress comes from adjusting the training dose—not simply increasing oxygen.
The practical distinction: acute hyperoxia may allow more work or less breathlessness at a given workload, but that does not guarantee superior long-term adaptation.
