Does anyone know the name of this martial arts/gymnastics flip?

Question

It's the one you always see in fight scenes when the guy gets knocked on his back, then he draws his knees up over his chest and springs back onto his feet.

Here's a clip of Jackie Chan doing it at about 1:32

Also it's the very first flip that the guy in the clip does:

It's called a kip or a kip up. I can do it, it's really fun.
