Your body was designed to do much more than just sit and stand. Your skeletal system comes equipped with over 180 joints and 650 muscle groups enabling you to execute an incredible variety of movements. This beautifully designed system of levers and cables provides you with the greatest all around motion machine on earth!
Climbing stairs, walking on pavement, plopping into the car seat etc. often exposes your body to loads 2-3 times that of your entire body weight. In order to handle the vast array of repetitive loadings, your body comes equipped with a multi-layer shock-absorbing system designed to allow movement to remain light and flexible and the joints remain strong and healthy.
At the primary level are the individual muscle fibers. Their piston-like functioning allows them to expand and contract as much as 30% without injury, making them ideally suited to absorb the shock of movement.
If the intensity of the shock is more than the local muscle groups can handle, then the next level of shock absorption comes to play in that the shock gets transferred across the joints and unto the surrounding muscle groups. The shock of movement usually experienced in the smaller, peripheral muscle groups of the hands and feet can thereby be efficiently passed onto the increasingly larger muscle groups found at the core of the body.
The over 650 different muscles are thus organized within 6 such major shock absorbing systems found in the feet, knees, spine and elbows. (see foto with arches drawn on it) enabling movement to become springlike and a great source of joy in your life.
Faulty structural alignment stops the shock of movement from being transferred to the next joint. The full force of the shock becomes focused on limited areas of cartilage within the joint itself or on sites of attachment between bone and tendon around the joint. Increased joint pain and decreased movement are the results.
Postural Muscle Function
There is a part of the sub-brain that stores samples of postures and motion that tend to repeat themselves. Dialing frequently used phone numbers, starting the car, writing your name etc. are all stored as mini-computer programs in the sub-brain.
Although driving stick shift, and writing your name were laborious tasks when you first had to learn them, now you can breeze through them almost without thought. The reason is that there is a part of your sub-brain that records and stores movements that you use repeatedly throughout the day. As the need arises, your brain simply activates the mini-motion programs that it already has stored in its data banks. Your body does the same with the various postures you tend to assume throughout the day. The typical postures you assume while standing, sitting at the computer. All become recorded and stored in your sub-brain.
Since the postural muscles are controlled subconsciously, the stiff and sore office worker, computer programmer, surgeon etc., who tries to straighten himself after a long stretch of work will experience only temporary relief. The moment his attention returns to his work, he will relapse back into his normal postural patterns and start cramping up all over again. In practice it is practically impossible to correct programmed postural deviations by constant willful attention.
