Ventilatory efficiency response is unaffected by fitness level, ergometer type, age or body mass index in male athletes.

The aim of this study was to evaluate the ventilatory efficiency ( /VCO slope) and the respiratory control (Vt/Ti slope) in a wide range of athletes and describe the influence of fitness level, age, ergometer type or BMI on these parameters. Ninety-one males (30.4±10.
