Controlling Center Line

Controlling the center line refers to the imaginary line that runs vertically through the center of a person's body, dividing it into left and right halves. By controlling this line, you dictate the opponent's movement, maintain dominant positioning, and create opportunities for attacks or defenses.

Key Elements

Head Control

  • The head dictates the direction of the body. By controlling your opponent’s head, you can restrict their movement and alignment.
  • Examples:
  • Using a crossface in Side Control Top to turn their head away.
  • Driving their chin toward their chest in a choke like the North South Choke.

Spine Alignment

  • Disrupting your opponent’s spinal alignment compromises their Base and ability to generate Hip Movement.
  • Examples:
  • Applying heavy Pressure to their upper body in Mount Top to flatten their spine.
  • Twisting their torso with positions like Gift Wrap or Twister.

Hip Control

  • The hips are the source of power and mobility. Controlling them prevents escapes and neutralizes attacks.
  • Examples:
  • Blocking their hips with your knee or hand in Side Control Top.
  • Controlling their pelvis in Guard passes like the Over-Under Pass.

Goals of Controlling Center Line

Restrict Movement

  • Limiting your opponent’s ability to align their head, spine, and hips reduces their ability to escape, frame, or attack effectively.

Establish Positional Dominance

Set Up Submissions

Applications of Center Line Control

Top Control

  • In Side Control Top, use chest-to-chest contact to pin their torso, crossface to control their head, and knee pressure to limit their hips.
  • From Mount Top, apply chest pressure to flatten their spine and isolate their arms by pinning them near their head.

Guard Passing

  • Control their hips and legs to disrupt their alignment and prevent them from recovering Guard.
  • Use grips or body positioning to block their movement and establish Side Control Top or Knee on Belly.

Submissions

  • Many submissions, like the Arm Triangle or Rear Naked Choke, work by isolating the opponent’s head and disrupting their center line alignment.
  • Leg attacks, like Heel Hooks, involve controlling the hips and spine to neutralize counters.

Defensive Strategies Against Center Line Control

Reestablish Alignment

Frame and Create Space

  • Push against the opponent’s chest, shoulders, or hips to relieve pressure and regain freedom of movement.

Common Mistakes in Controlling Center Line

Overcommitting to One Area

  • Focusing solely on the head or hips while neglecting the other can lead to escapes or counters.

Neglecting Weight Distribution

  • Improper balance reduces your ability to apply consistent pressure and can expose you to sweeps or reversals.

Ignoring Frames

  • Failing to clear your opponent’s defensive structures makes it harder to maintain control.

Drills to Practice Center Line Control

Crossface and Underhook Drills

Positional Sparring

  • Start in dominant positions like Mount Top or Side Control Top and focus on maintaining center line control against an escaping opponent.

Guard Passing with Hips Control

Tip

Controlling Center Line is about dominating the fundamental axis of movement in your opponent’s body. Focus on combining Pressure, Frames, and Weight Distribution to limit their options and create openings for submissions or positional advancements.
