Implication

Clinicians should not yet target lungs to raise VO2max; leaves open whether pulmonary limits emerge after maximal downstream adaptation.

Structured PICO

P
Population
Mammals, including 'athletic' species and endurance-trained human athletes
O
Outcome
Limits for oxygen and substrate transport

Highlights that while the heart, microcirculation, and muscle mitochondria can adapt to increase oxygen flux, the lungs lack malleability and may ultimately limit VO2max.
