How can figure skaters do so many spins at such a high speed without getting dizzy and falling down?

they don't let their head spin with their body. they stop it, then turn it quickly to catch up.

Actually Shelley L you are wrong when doing a spin (not rotating footwork that is different) like the ones you are describing: sitspin etc. The skater keeps thier eyes open and stays centered on the "sweet spot" of their blade a figure skater NEVER spots while doing spins! EVER!!! Pretty much, it is just practice. sorry to disappoint, lol Also spinning in a chair is VERY different, and you will get MORE dizzy if you close your eyes and just to let you know trying to spin around on two feet as fast as you can doesn't work either xP even i get dizzy if i spin on a chair... and if i EVER closed my eyes doing spins at my rink i don't think i would open them again at most rinks during practice time there are alot of highly competative skaters (if you are @ a level where you are doing fairly advanced tricks) and closing your eyes while doing any move is a bad idea Also we DO get dizzy sometimes the better you are the less often but i have mastered the basic spins and if i do too many in a combination or go abnormally fast i will get a little dizzy you just hafta snap outa it really quickly so you don't get killed! lol sorry for the long answer hope that cleared things up!

Someone who chooses to be a professional skater does not have a brain, therefore they can spin many times without falling.

They practice alot and their heads aren't turning as fast as the legs.

your body becomes accustomed to it. you can spin around circles everyday and get dizzy. eventually, it will take more spins to get you dizzy.

Practice, practice, practice

they can't at first but then they get used to it....

THey do it alot
