A brief word on extensibilityflexibility

A thorough explanation of proper stretching procedures would require a whole book in itself and it is outside the scope of this one. However, the following figure illustrates the various factors involved in having an optimal range of motion.

The following structures can influence the actual range of motion:

a) Muscle structures: A muscle with proper extensibility is generally associated with an optimal usable range of motion.

b) Ligaments and joint structures: The ligaments can limit the range of motion due to their role as joint stabilizers. On the other hand, ligaments that are too loose can also be problematic, causing joint instability.

c) The nervous system: Sometimes there will be a lack in usable range of motion despite adequate extensibility of the muscles and ligaments. In this case the nervous system can be the cause of the lack of range of motion, not allowing the muscles to work throughout their complete amplitude.

d) Other factors: Elasticity of the skin, adhesions between the muscle fibers, and adhesions between the muscle and its fascia.

This tells us that several stretching techniques should be used. If the problem is structural, static stretching will be adequate. But more advanced techniques such as PNF or ballistic stretching become necessary to solve range of motion problems due to neural factors. If adhesions are the cause of the problem an ART treatment is the best solution.

I already know two things about you. You are an intelligent person who has a weighty problem. I know that you are intelligent because you are seeking help to solve your problem and that is always the second step to solving a problem. The first one is acknowledging that there is, in fact, a problem that needs to be solved.
