Abstract Purpose Continuous incremental protocols (CP) may misestimate the maximum aerobic velocity (V max ) due to increases in running speed faster than cardiorespiratory/metabolic adjustments. A higher capacity mitigate this issue pulmonary oxygen uptake ( $$\dot{V}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mover> <mml:mi>V</mml:mi> <mml:mo>˙</mml:mo> </mml:mover> </mml:math> O 2 kinetics. Therefore, study aimed compare three different assess V athletes with or lower training status. Methods Sixteen well-trained runners were classified according (HI) (LO) 2max -kinetics was calculated across four 5-min bouts at 10 km·h −1 . Two CPs [1 per min (CP1) and 1 every 2-min (CP2)] performed determine , lactate-threshold submaximal /velocity relationship. Results compared discontinuous protocol (DP).

Conclusions Higher status witnessed by kinetics led between-protocol differences, particularly between DP. Faster minimize mismatch issues metabolic mechanical power that occur CP.
