TransliterationTranslation: quarter sprawl
Overview
The Quarter Sprawl subfamily covers the partial sprawl technique where the defender sprawls only one hip back, defending a single-leg takedown attempt by removing only the attacked leg. [1] The quarter sprawl is faster than a full sprawl because it requires less body displacement — only one hip moves backward while the other remains forward. [1],[2] The quarter sprawl is the preferred defence against single-leg takedowns because it specifically addresses the attacked leg while maintaining a base with the non-attacked leg. [2],[3]

Biomechanical Mechanism
Primary Action — Driving the hips backward and downward to prevent the opponent from completing a level change or takedown entry
Joints Involved — Hips (explosive rearward thrust), legs (extending to drop weight), chest (driving down onto opponent's back)
Force Vector — Downward and rearward — hips drop to the mat while weight drives onto the opponent's shoulders and head
Defensive Mechanic — Sprawling eliminates the attacker's penetration angle — dead weight on their upper body prevents completion of the shot
Position & Entry
From fighting stance (opponent shoots) — When the opponent level changes for a takedown, thrust the hips backward and down, driving chest onto their upper back
As reactive defence — Detect the level change and immediately kick the legs backward while dropping the hips to the mat

✓The quarter sprawl is a partial hip check used against lighter shots or when the full sprawl isn't needed — drop one hip back while using the hands to redirect the opponent's head (Couture, Wrestling for Fighting, 2007)
✓The quarter sprawl is faster than the full sprawl — it uses one leg to check the shot while maintaining a more upright position
✓Use the quarter sprawl against: outside single legs, snatch singles, and shots that don't fully penetrate the stance
✓The quarter sprawl keeps you in better position to counter-strike — you remain more upright than the full sprawl
✓Against the single leg, the quarter sprawl on the attacked side checks the shot while the opposite hand frames on the opponent's head
✓The quarter sprawl is the MMA-specific adaptation — fighters need to sprawl while maintaining striking posture
✓Combine the quarter sprawl with a knee tap or snap down for an immediate offensive counter
Common Mistakes
!Using the quarter sprawl against a fully committed double leg — a deep shot requires a full sprawl; the quarter sprawl won't stop it
!Not checking with enough hip force — the quarter sprawl still requires a meaningful hip drop on one side
!Leaning back instead of dropping the hip — the hip must go backward, not the torso backward
!Not controlling the opponent's head after the quarter sprawl — hand control on the head prevents the opponent from continuing
!Using the quarter sprawl exclusively — have both the quarter and full sprawl in your toolkit and choose based on the shot
!Standing too upright after the quarter sprawl without re-establishing stance — return to your fighting stance immediately
!Not training the quarter sprawl specifically — most fighters only drill the full sprawl and improvise the quarter version

Frequently Asked Questions
What's the difference between a quarter nelson and a three-quarter stack?
In the three-quarter stack from sprawl control, you use a whizzer (arm pressure) combined with a hand on the head pushed down hard. The Modesto Judo Club instructor emphasizes that this hand-on-head pressure with downward force is the key attacking position from sprawl control.
How do I stop my opponent from rolling out of a quarter sprawl?
You need to feel and recognize when your opponent attempts to somersault or roll out, similar to how you learn to sense an X-Guard threat. The Modesto Judo Club instructor stresses that you must develop sensitivity to detect the escape attempt early.
What kind of pressure should I apply with my hand on the head in this position?
Apply downward pressure by stuffing hard with your hand on the head while maintaining your whizzer arm position. The Modesto Judo Club instructor demonstrates this as a crucial control element that limits your opponent's mobility.
