Oxygen uptake efficiency plateau is unaffected by fitness level - the NOODLE study.

ABSTRACT:

Background

Endurance athletes (EA) are an emerging population of focus for cardiovascular health. The oxygen uptake efficiency plateau (OUEP) is the levelling-off period of ratio between oxygen uptake (VO₂) and ventilation (VE). In the cohort of EA, we externally validated prediction models for OUEP and derived with internal validation a new equation.

Methods

140 EA underwent a medical assessment and maximal cycling cardiopulmonary exercise test. Participants were 55% male (N = 77, age = 21.4 ± 4.8 years, BMI = 22.6 ± 1.7 kg·m^- 2, peak VO₂ = 4.40 ± 0.64 L·min^- 1) and 45% female (N = 63, age = 23.4 ± 4.3 years, BMI = 22.1 ± 1.6 kg·m^- 2, peak VO₂ = 3.21 ± 0.48 L·min^- 1). OUEP was defined as the highes
