Benefit of slapping legs pre race?

Reactive hyperemia

scientific word for inducing pure hate into your limbs

I think paralympic athletes were banned from "boosting", does this come under that? ;)

Some paralympic athletes self-harm for competitive edge | CBC News

Several paralympic athletes may be intentionally damaging their own bodies -- sitting on pins, cracking toes, twisting scrotums -- to kick start their nervous systems in a banned practice known as "boosting."

I'd heard that Sha'dopey Richardson is generally considered to be a bit of a slapper - is that right?

it's like getting a hug when you're stressed out; it encourages the muscles to release excess tension

granted, some people literally just slap their skin like they're in the video they were secretly watching the night before, which in that case maybe they get turned on psychologically and benefit from the increased pain threshold seen during arousal

I only do it because it reminds me of the good times I had with your mother.

Seems to be something people do when they are nervous at the line. Of course it doesn’t actually help. But some people just dont know what to do and they are stabding there so it feels better to pretend you know what you are doing by shaking your legs, jumping high in the air, or slapping your legs a bunch. Its just a way for someone to let out their nerves.

Benefit is everyone gives you plenty of room in the pack, because they think you're mental.
