When ballet dancers whirl around their toes, they will focus on the fixed point to avoid dizziness, and then turn around quickly when the neck is twisted to the limit.
Skaters rotate much faster in place, this method can’t be done, and it’s not safe. They mainly keep their sights at the same level, so that the sights seen will only rotate around an axis. Long practice can gradually train the ability to overcome dizziness.
In addition, many fancy skaters add a dance action to the long-term rotation to provide a buffer time for the dizziness to disappear.
