A sprawl is a martial arts and wrestling term for a defensive technique that is done in response to certain takedown attempts, typically double or single leg takedown attempts. The sprawl is performed by scooting the legs backwards, so as to land on the upper back of the opponent attempting the takedown. The resultant position is also known as a sprawl or sprawling position.
Ideally, the sprawling combatant should arch his back as much as possible and keep his knees off the floor. His options from the sprawl include attempting to gain leverage on the lower back by hooking underneath the elbows, throwing in a headlock, and grabbing his opponent's ankles and trying to get behind his opponent.
