The on‐and off‐transient (ie phase II) responses of pulmonary oxygen uptake (V̇O2) to
moderate‐intensity exercise (ie below the lactate threshold, θL) in humans has been shown
to conform to both mono‐exponentiality and 'on‐off'symmetry, consistent with a system
manifesting linear control dynamics. However above θL the V̇O2 kinetics have been
shown to be more complex: during high‐intensity exercise neither mono‐exponentiality nor
'on‐off'symmetry have been shown to appropriately characterise the V̇O2 response …
