Muscle functions

Deeper consideration on my back muscles led me to some conclusion that the stiffness of muscles are caused by the situation of keeping the same position for long time with concentration.

The muscles tension are in the tendency of lack of cell sap supply.
Basically the business for muscles are to shrink to perform working, so the situation keeping contracted figure so long time as to loosing the normal cell sap circulation.
In order to recover this inconvenient situation the muscles must be contracted intentionally however pain may be caused in the way.

The recovery of fundamental liquid circulation is once started, we will soon feel some itching sensation on the portion, this is caused by the change of biochemical compositions in body cell sap, Adenosin Phosphate and Lactic Acid.

Also the joint dysfunctions are mainly caused by the continuous shrinking power of muscle spasm, on neck ,back and low back.

Remember that mechanical rough vibrations easily causes the ruptures of peripheral vascular so the muscles should be treated gently parallel to the muscle functional direction and above all the contractions is the best way to recover the original power that is superior to any of the external stimulation.
