Training Coordination | PE Training Solutions -->

I was asked a great question on how should we be training coordination and where it occurs in the human body. When I think about coordination I think about the proprioceptors that live throughout our human body. Proprioceptors are a transducer or converter like sensory organ that are used to coordinate movement. Proprioceptors sense physical forces and convert them into an electrical signal unconsciously. Information from each single proprioceptor can mean more than one thing to the body so the more information the body can receive from multiple proprioceptors the clearer the picture. But in many cases most of our proprioceptors do not function optimally due to lack of use in our sedentary lives and our training. The more authentic and functional a movement is the greater the role the proprioceptors play in the success of that movement. Here are a few examples of proprioceptors and their functions:

Pacinian Corpuscles- Stimulated by acceleration and deceleration
Located in the joint capsule but more in distal joints
Low threshold before firing
Rapidly adapts to constant stimulus
They ask is this movement speeding up for slowing down?

Golgi-Mazzoni Corpuscles-Stimulated by compression perpendicular to the surface
Located in capsule near attachment to bones
High Threshold before firing
slowly adapts to constant stimulus
They ask if a movement is at the bodies end ROM?

Ruffini Endings-Stimulated by speed and tension
Located in capsule but more in proximal joints
Slowly adapts to constant stimulus
Is speed good or bad? Can I stabilize my lower extremity while I reach to catch at ball at this speed?

Golgi Ligament Endings- Stimulated by tension
located in ligaments
low and high thresholds before firing
slowly adapts to constant stimulus
Are they stimulated in normal function? Low threshold endings inform about normal motion high ending warn of tear? If motion that caused injury is avoided then the system is deprived of valuable information EX:ACL rehab

Golgi Tendon organs-Stimulated by tension
Located in Tendon
Low and High thresholds
Slowly adapts to constant stimulus
High thresholds fire muscle may be inhibited to prevent injury low threshold give information to muscle about level of tension. EX decelerating after a throw

Muscle Spindles-Stimulated by changes in muscle length
located with muscle fibers and has contractile section
Muscle spindles act like tension gauge
ROM might be adequate on a table but very restricted during function due to lack of muscle spindles sending information.

Fascial Tissues
The Fascia plays a role in force transmission and attenuation
The Fascia may have a more important role in providing information that organize all parts of the body.

So getting back to the question of where does coordination reside in the human body my answer would be the proprioceptors.

How do you train it? In my opinion you have to train it by first placing our bodies in successful environments that we function in and take into account gravity, mass & momentum, and ground reaction forces. These are constants that our body must deal with in function. And if we train and rehabilitate the body with the proprioceptors in mind I think we can create a body that can adapt with a high functional threshold leading to less injuries. For example, we could take an anterior lunge and tweak the range of motion (ROM) we would call on the Golgi-Mazzonis to activate and then tweak the speed of the lunge to activate the Pacinian Corpuscles. So when we are in function and our body lunges to end ROM the Golgi-Mazzoni corpuscles have been there before and understand how to decelerate that motion under that speed along with the Pacinian Corpuscles. With those tweaks our body gains more information and makes stronger connections increasing our functional ability.
I also can’t help but to think about traditional ACL rehabilitation, in the past I overlooked the proprioceptive system and was focused on strength ratios and other forms of measurement. Leg extensions and leg curls dominate some ACL rehabilitation programs right up to the point of release. But, the body is not being trained to deal with gravity, mass & momentum, and ground reaction forces along with lack of functional proprioceptive input. Overall if I was training coordination I would train the proprioceptive systems.
