I am asking about how someone will get knocked down and then they will "pop up" on to their feet in a jumping motion, from back to feet.
How do you get up off the floor without using your hands like a ninja in a martial arts movie?
The most common 'uprise' technique is called a 'kip'. It's a gymnastics movement best illustrated by Jackie Chan, who is often shown diving backwards to evade a strike, so that he lands on the floor on his shoulderblades, with his legs above his body (like a crouching position, but upside-down). Depending on the direction of the dive, this position could be used to slide backwards along the floor (a shallow dive), or continued into a backward roll (a short dive, like a back-somersault without any height).
By landing in between these two positions (so that his weight is balanced over his shoulderblades), Chan can reverse the movement, kicking his legs into the air forcefully so that his curled-up body will 'spring' back up into the air, almost following the same path as his dive did.
In acrobatics, the 'kip' is usually assisted by pushing the ground with your hands, on either side of your neck.
The other popular technique is a 'windmill'.
By moving one leg across the other, and continuing this movement as if drawing a large, horizontal circle with your foot (about 18 inches above the ground), you can start a twisting movement that will affect the whole of your bodyweight. As the first foot passes the centreline of your body (above your head), the other foot can start to follow its circular path, so that both legs are almost rotating opposite each other (as if your body was a helicopter; your legs are the rotor blades).
If this rotation is suddenly stopped (about a quarter of a rotation later, the first leg is 'chopped' down to the mat, like an 'axe kick', while the second is thrown forcefully outwards on the opposite side of your body), this will transfer momentum to your torso, and 'lever' you into a half-kneeling ('rifleman's') position, rotated 90 degrees from the direction your feet were pointing towards when you were lying.
Timing is very important in getting this move right, and there are numerous variations.
Sadly, the most spectacular of the 'uprise' movements seen in chop-sockey movies are impossible, even for ninjas. They are achieved using wires (traditionally, many thin black wires that are impossible to see from a distance of more than two feet away, but nowadays larger cables are used, and digitally edited out).
Many gravity-defying moves (such as blows that are so powerful that the recipient rotates many times in the air before hitting the ground) are achieved with the help of these 'wire' techniques, and objects are also manipulated in this way. The use of wires for 'flying combat' is only a small part of the repertoire of wire tricks that can be (and have been since the fifties) used in filming martial-arts combat.
Reply:i doubt real ninjas would do that to get up. you're pretty exposed to attacks when getting up like that. but if you are learning if just for fun its called a "kipup"
Reply:Kickouts are what your talking about. It takes high agility and strength, unless you are just born with the natural ability.
But in reality, such a move would almost NEVER be used. If someone was punching in, you would jump up right into their fist. They are great for workouts and flashy moves, but in reality, the wiser man uses quick, effective moves instead of the really difficult, energy-burning ones. It also leaves you very exposed for that split second, where anything could happen. It leaves your core wide open, and its takes a lot out of you, leaving you with less energy when you get up. I'd just trip to leg, or just get up since I practice quick counters a lot.
