Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
An apparatus for increasing respiratory tidal volume of athletes comprising: T-shaped mouthpiece means for respiring, having three unobstructed passages, a first passage communicating with the mouth of said athlete and comprising the vertical member of said T-shape, and second and third passages, positioned to oppose each other as the respective members of the horizontal section of said T-shape, said second and third passages easily communicating with each other and with said first passage; two unobstructed flexible tubes, each joined at one end to said mouthpiece means at said second and third passages, and each tube open to the atmosphere at the other end to permit unobstructed inflow and outflow; and means appending the open ends of said tubes in proximity with each other, said apparatus configured such that the entire apparatus lies in substantially the same horizontal plane when in use by the athlete.
Claim 2
Independent Claim

An apparatus for increasing respiratory tidal volume of athletes comprising: T-shaped mouthpiece means for respiring, having three unobstructed passages, a first passage communicating with the mouth of said athlete and comprising the vertical member of said T-shape, and second and third passages, positioned to oppose each other as the respective members of the horizontal section of said T-shape, said second and third passages easily communicating with each other and with said first passage; two unobstructed flexible tubes, each joined at one end to said mouthpiece means at said second and third passages, and each tube open to the atmosphere at the other end to permit unobstructed inflow and outflow; and means appending the open ends of said tubes in proximity with each other, said apparatus configured such that the entire apparatus lies in substantially the same horizontal plane when in use by the athlete.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein the total volume within said two tubes is between 500 ml and 1000 ml.
