ABSTRACT:
An apparatus for increasing the respiratory tidal volume of athletes is described. The invention provides additional volume to the anatomical dead space requiring the athlete to ventilate at a higher rate than that dictated by the actual work or training being done. This results in a respiratory effort in excess of the respiratory requirement.
