Hey, Attention on Deck!

Hey, NOTHING here is PERSONAL, get over it - Teach Me and I will Learn!

When you begin to feel like you are a tough guy, a warrior, a master of the martial arts or that you have lived a tough life, just take a moment and get some perspective with the following:

I've stopped knives that were coming to disembowel me

I've clawed for my gun while bullets ripped past me

I've dodged as someone tried to put an ax in my skull

I've fought screaming steel and left rubber on the road to avoid death

I've clawed broken glass out of my body after their opening attack failed

I've spit blood and body parts and broke strangle holds before gouging eyes

I've charged into fires, fought through blizzards and run from tornados

I've survived being hunted by gangs, killers and contract killers

The streets were my home, I hunted in the night and was hunted in turn

Please don't brag to me that you're a survivor because someone hit you. And don't tell me how 'tough' you are because of your training. As much as I've been through I know people who have survived much, much worse. - Marc MacYoung

The content surrounding the extracts of books, see bibliography on this blog site, are also mine and mine alone therefore errors and omissions are also mine and mine alone and therefore why I highly recommended one read, study, research and fact find the material for clarity. My effort here is self-clarity toward a fuller understanding of the subject matter. See the bibliography for information on the books. Please make note that this article/post is my personal analysis of the subject and the information used was chosen or picked by me. It is not an analysis piece because it lacks complete and comprehensive research, it was not adequately and completely investigated and it is not balanced, i.e., it is my personal view without the views of others including subject experts, etc. Look at this as “Infotainment rather then expert research.” This is an opinion/editorial article/post meant to persuade the reader to think, decide and accept or reject my premise. It is an attempt to cause change or reinforce attitudes, beliefs and values as they apply to martial arts and/or self-defense. It is merely a commentary on the subject in the particular article presented.

“You should prepare yourself to dedicate at least five or six years to your training and practice to understand the philosophy and physiokinetics of martial arts and karate so that you can understand the true spirit of everything and dedicate your mind, body and spirit to the discipline of the art.” - cejames (note: you are on your own, make sure you get expert hands-on guidance in all things martial and self-defense)

Sanchin or Dynamic Tension or Isometrics

Recently I have been re-introduced to the sanchin kata of Isshinryu. Sanchin is a dynamic tension moving isometric type kata. What I mean is dynamic tension or isometric exercises, i.e. a type of strength training where a combination of joint angles and muscle length are contracted in a static position where isometric exercises done through a range of motions are referred to as dynamic. 

What you are actually doing is a combination of both isometric and dynamic tensioning, i.e. you remain in a static position while working muscle agains muscles by resistance. Then you move into the dynamic tension part where you overcome the isometric, the joints and muscles work against an immovable force. 

Sanchin or dynamic tension movement tends to work better in building muscle and strength. You can safely do a 110 percent effort and continue so with effort remaining at 110 percent as strength is depleted thus allowing for longer periods with maximum volitional tensioning. 

Sanchin involves the static contraction of muscle with movement while maintaining the principles of martial systems, i.e. alignment of skeletal systems such as joints and spinal alignment along with structure, posture, centerline, heaviness, centeredness, etc. When you consider dynamic tension as executed through the Charles Atlas systems and dynamic tensioning in Sanchin you get a more well rounded and complete exercise with karate's sanchin provided you adhere to all the principles involved, i.e. "Breathing, Posture, Triangle Guard, Centerline, Primary Gate, Spinal Alignment, Axis, Minor Axis, Structure, Heaviness, Relaxation, Wave Energy, Convergence, Centeredness, Triangulation Point, The Dynamic Sphere, Body-Mind, Void, Centripetal Force, Centrifugal Force, Sequential Locking & Sequential Relaxation, Peripheral Vision, Tactile Sensitivity, and Rooting."

When performing sanchin you adhere to the principles as described above along with using just the bodies structure and skeletal/muscular/cardio/breathing systems in unison, as one whole system working together as a wholehearted unit. 

One caveat, since sanchin involves dynamic tensioning that results in a temporary spike to internal pressures such as blood pressure you must first get your personal physician to certify your health just in case you are one of those persons who currently suffer from higher blood pressures or even susceptibility to strokes, etc. There is no evidence or research that says dynamic tension, isometrics or sanchin (a combination of both dynamic tension and isometrics) will result in high blood pressure or be the cause of strokes, etc. It is better to be safe in the case of sanchin practice and training. The benefits are there with health caution as the prerequisite to sanchin practice. 

p.s. dynamic tension/isometrics are also found in practices such as yoga or oriental martial arts and bodybuilding.
