Entering a room with violence requires the ability to produce a high force of movement with your eyes up, maintaining visual clarity, and control deceleration into a stable shooting platform.
These are all key capabilities of the vestibular system.
Eyes Up
Moving with your eyes up depends on your vestibular and proprioceptive systems to maintain precision of your footwork and trunk positioning over your feet. If these systems aren’t trained at a high level, you’ll lose precision or speed of footwork when your eyes are up.
Maintaining Visual Clarity
The vestibular system is responsible for maintaining visual clarity with movement. High acceleration movements place an increased demand on vestibular function to maintain that visual focus.
Control Deceleration
It is one thing to generate acceleration, another to rapidly decelerate into a stable platform to shoot from. The vestibulo-spinal reflex (VSR) is fundamental to this skill. The speed and accuracy of the VSR directly impacts the ability to move with violence into a stable shooting platform.
540° of Security
Violence of action must be multiplanar to achieve 540° of security. Because I see through the lens of vestibular demands, I look at six planes of movement. Each plane requires violence of action; therefore, each plane requires eyes up, visual clarity, and control of deceleration.
Digging your corners is an angular turning movement in the yaw plane, cutting the pie is an angular roll plane, securing above and below are angular pitch plane movements. Lateral shuffles are linear lateral movements, initial entries are in the linear forward/backward plane and rising from a kneeling position places demand on the linear up/down plane.
Moving with violence is dependent on the vestibular system. Multiplanar training of this skill contributes to 540° of security and cognitive processing, since you only move as fast as you can think or process. It’s hard to think and make good decisions if you don’t have visual clarity or a stable platform to engage from.
