I understand what you mean, but according to an Oxford Dictionary definition of "spike", which isIf you don't give enough effort and focus to do it right, then the spinning would make you dizzy.
I understand dancers use methods like focusing their eyes on one spot and keeping their head still then snapping it over repeatedly and so on, to avoid getting dizzy. Probably other methods too, which would require a great deal of effort.
Spike your effort in order to avoid messing up in your moves, thus getting dizzy. Not saying that is what spike means, just that it fits.
