This is by far one of my favorite tricks to do along with butterfly kick and butterfly twists, (they link up really easily) but a parafuso actually shows how well the human body takes linear momentum and converts it to angular momentum but adding the upward force.
The ginga (pronounced like jinga) is the building and wind up guard of this martial art. it has the leg back on one side and the arm back on the other. This basically gives range of motion to throw parts of the body into motion with more anticipation and control. But the first thing you'll notice is the 180 turn before he jumps. This turn causes the initial linear-angular transition as the hips are bent forward. Next he throws his arms into the angle to gain momentum from their mass, and the legs are swung around until either both can land (regular) or the first leg to take off is tucked back and you over turn the kick into a 540.
This trick is done 'perfectly' when the middle of the kick can be as far back as if one were lying down, where the transition from linear to angular momentum would be the most efficient, and also where the most height can be reached by the kick itself, allowing the momentum afterwards to carry through to the next motion.
