and the year Tonya Harding became the first American woman to perform a triple axel in competition.

The famous rivalry that bloomed is the one between Tonya Harding and Nancy Kerrigan.

And in 1991 at the Target Center in Minneapolis, MN, that meant:

And the triple axel is the 58 frames at the heart of that elegant/powerful split.

Mirai Nagasu's the only other America woman to land a triple axel in competition,

and when you ask her to define it in one word:

And the thing is, the more you know about the triple axel, the more impressive it gets.

"Jump. Jump to it, to it, you know you want to do it do it.”

"Jump to it, to it, you know you want to-

The triple axel really starts with the approach.

The triple axel has a forward takeoff where the skater pushes off the outside edge of

the skate, unlike say, a toe loop, where the jumper relies on the toe of their skate to

The approach is also forward instead of backwards.

Axels are forward-edge jumps, landing backwards on the opposite foot.

Because they turn from facing front to facing backwards, it's an extra half rotation,

Deborah King's studied figure skating and the biomechanics of single, double, and triple

“They need to generate the vertical velocity, but they also need to generate their angular

momentum, or their rotational momentum for the jump, and that's all gotta happen during

You'll see skaters with a slight skid on the ice that helps, but most of the twist

Once you're in the air, you have to deal with what you generated on the ice.

But rotation speed makes or breaks a triple axel.

This chart shows a small sample of single, double, and triple axel jumps.

You can see the triple axel jump length is often shorter than the double axel length.

That's because that extra energy is going into extra rotation.

Harding needed to snap into a tight rotation as quickly as possible.

“But in terms of body position, you don't want your elbows sticking out, you don't

want your arms right out in front of you, you don't want your knees sticking out,

you should look sort of as close as you can to a pencil.”

Skaters have to use a lot of upper body strength to keep their arms tucked in so it won't

It's only once they've spun three and a half times in the air that they can start

And then, their big obstacle is slowing down.

Skaters try to land on the ball of their opposite foot to absorb the speed of the rotation and

Midori Ito was the first woman to do a triple axel in world competition in the late '80s.

When she wobbles like this or Tonya Harding nearly falls over,

they're compensating for a huge rotational velocity, all the while trying to look good.

A triple axel turns physics into poetry, and that's probably the reason it's hard to

In the triple axel, power and elegance are complements, not contradictions.

But in the Target Center in Minneapolis, Minnesota?

“Oh the zamboni's coming out, it's gonna be loud.”
