All that you have ever experienced, will ever experience, all the exercises or personal bests you have ever pulled off have started and ended in your brain.
All movement, skill, thought, and everything that makes you, you is encompassed in this 3lb organ.
You bet your arse it does!
Now, this isn't a neurology lecture but before we get into how important the way your brain gathers information is and how to improve it, we need to, in a very basic way understand how the brain works.
Your brain uses sensory inputs to gather information. These sensors receive input and the peripheral nervous system (PNS) and the central nervous system (CNS) sends these signals to the brain which then basically decides the action and then creates motor output relevant to whatever was decided.
At a very basic level that's it.
The brain has three ways to gather information or inputs:
These inputs are then integrated together to build and update the brain's map of everything. Of you, the world around you and how you are moving through it. The brain updates previous experiences, senses, and predictive processes to make decisions that drive the body's actions.
Now that we broadly understand how the brain does things, we need to figure out why it does them.
Well, the answer to that one is easy: survival.
Your brain's goal is to keep you alive. Full stop. Not keep you alive ten years from now but right now, today.
How it does this is through prediction. Our brains are masters at pattern recognition. Every second of every day the 120 billion neurons in the brain are processing information based on previous experience to predict outcomes to actions, this is your brain using pattern recognition to decide actions.
There is a hierarchy to the inputs your brain uses to move through the world:
If these sensory inputs match (i.e. there is clear information from all three systems and there is good integration in the brain) your brain will allow you to function well and perform when it matters. Whether that's CrossFit, powerlifting, or just picking something up of the floor.
When there is a mismatch is when we run into problems. If there is bad information informing the brain maps and pattern recognition abilities, then I am afraid it is going to try to limit the chances of death---usually by generating pain to draw attention or inhibiting movement.
In this article, I am going to focus on exercises to improve your visual system as 70-90% of all sensory input is visual.
There are two classifications of vision in humans:
There could be any number of things affecting these two patterns and hindering your visual system, which in turn could be dramatically holding your performance back without you even knowing it.
The key to training your visual system for performance is training the musculature of the eyes to function correctly. After all, poor muscular function will cause problems in gaze shifting and gaze stabilization.
We are going to cover one drill for stabilization and one for shifting. Reference my video for a demonstration of each drill.
I recommend you record yourself performing the drill and watch it back to see how you perform. That way, you can adjust accordingly.
Stand in a neutral stance holding a pen out in front of you in a neutral position.
Try to smoothly follow the pen as you move it from neutral into one of the eight positions below and then back to neutral:
You should repeat this test three times in each of the eight positions. You will be looking for two things when you watch the drill back:
Each of these can indicate poor visual-motor control.
The aim of these drills is to get your eyes functioning properly so the information your brain gets is as clear as possible . That way your brain won't be afraid to let you move fully in all of your available ranges of motion.
Remember, when the brain can predict, you can perform.
