It's the Olympics, and it'll be one the world won't soon forget. The sprinters are in position on the starting blocks, the signal is given and the runners are off! However, one man gives off a fart so huge that it significantly boosts his acceleration. This mother of all farts propels him all the way to a first-place finish and a trophy on a pedestal. Cue a training montage flashback where our protagonist learns the art of fine muscular control in a remote mountaintop monastery.
My question is this: is it mechanically viable for a male athlete weighing approximately 80kg to use rapid anal gas expulsion (AKA flatulence) as a form of assisted take off or even as a nitro boost?
Main problems with this idea that I've identified:
Fart propulsion might have too low a thrust-to-weight ratio for this purpose
The human body might not be able to store enough gas for this purpose
