No word is more fitting to describe dramatic change in singles figure skating than revolution.

Two of the discipline’s three elements, jumps and spins, involve revolving in the air or on the ice. The third element, footwork, often includes pirouettes of one or more turns.

And the dramatic change this season is a female revolution based on a single additional turn.

Young women are turning the quadruple jump into a key element of singles skating, pushing the technical side of their discipline forward at a pace that seemed unimaginable only three years ago.
