V˙O2 linear-onset kinetics spanning steady- and non-steady-state exercise
The LO <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow><mml:mover><mml:mi>V</mml:mi> <mml:mo>˙</mml:mo></mml:mover> </mml:mrow> </mml:math> O<sub>2</sub> kinetics method is superior to the traditional approach as it was a more valid representation of the initial <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow><mml:mover><mml:mi>V</mml:mi> <mml:mo>˙</mml:mo></mml:mover> </mml:mrow> </mml:math> O<sub>2</sub> response, can be applied to both steady and non-steady state exercise intensities, requires less than 2 min of exercise, but across multiple bouts, and identifies more complex physiology than the mono-exponential method. Added research is needed to discern the most valid methods to measure LO <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow><mml:mover><mml:mi>V</mml:mi> <mml:mo>˙</mml:mo></mml:mover> </mml:mrow> </mml:math> O<sub>2</sub> kinetics, and to learn more about its physiological determinants compared to the traditional mono-exponential method.
