Is the Ventilatory Efficiency in Endurance Athletes Different?-Findings from the NOODLE Study.

ABSTRACT: Background: Ventilatory efficiency (VE/VCO₂) is a strong predictor of cardiovascular diseases and defines individuals' responses to exercise. Its characteristics among endurance athletes (EA) remain understudied. In a cohort of EA, we aimed to (1) investigate the relationship between different methods of calculation of VE/VCO₂ and (2) externally validate prediction equations for VE/VCO₂. Methods: In total, 140 EA (55% males; age = 22.7 ± 4.6 yrs; BMI = 22.6 ± 1.7 kg·m^-2; peak oxygen uptake = 3.86 ± 0.82 L·min^-1) underwent an effort-limited cycling cardiopulmonary exercise test. VE/VCO₂ was first calculated to ventilatory threshold (VE/VCO₂-slope), as the lowest 30-s average (VE/VCO₂-Nadir)
