why do we use dynamic tension on certain movements in kata ?

Hi Kiba,

Dynamic tension is a way of conditioning the body to withstand strikes, by contracting our muscles and combining this with deep energetic breathing we can also gain internal health benefits, a bit like an internal massage, by doing this new blood is pushed into the internal organs also we're training the body to go from relaxed to tensed which is vital in transferring power, regards,

James.

Hello James:

<<Dynamic tension is a way of conditioning the body to withstand strikes

Is the ultimate end of your idea, (this idea) to withstand any/all strikes ? Is there such a thing as silly ~melodrama~ in that regard?

<<by contracting our muscles and combining this with deep energetic breathing we can also gain internal health benefits

Specifically such as?

Which is the "critical" aspect IYP... the contraction or the release of that contraction? What value of the latter

J

Ronin...do you have an answer to the original question?

The value of the release of contraction is to allow the weapon (fist, elbow, foot, etc)...to be delivered unimpeded from the contraction of the body that caused the acceleration of said weapon in the first place. Dynamic tension trains the body to move from a states of tension and relaxation within a split second. It also trains the body to use its entire muscular system in unisonous as opposed to in isolation which many conditioning and weight training drills.

With regards to the internal health benefits James already stated about the internal massage. Anyone familiar with the benefits of an external massage should be able to figure out the benefits of an internal massage caused by the contraction and relaxation of internal system.

good question.
It's for learning how to store 'potential energy' within your body. when you stretch or tourque a rubber-band...you are storing potential energy within the band. during an event, the idea is your potential energy is constantly being wound and released...the release charges your next potential.
Doing this slow-motion in kata (or any technique) eventually leads to being able to do it full-speed and without thinking.

think of one of those things...ummm...ah hell here's a pic, it's easier lol:

Hi Ronin,

Cant see any value in your post because you haven't actually contributed anything, just nit picked!

Actually my ultimate goal is to not be struck at all, if i'm not there in the first place i won't get hit! regards,

For what its worth I used to train sanchin - hard. After a couple of years I could withstand alot more punishment withoubt a doubt.

It certainly works IMO however I elect not to train the Sanchin hard these days as it essentially conflicts with my core Shorin Ryu principles if im being fussy.

however I do train it 'soft' with great results and whilst im not getting the iron shirt benefits externally I believe it is a very healthy excersise for internal strength and ki development and flow, among other things.

Hello Harlan:

<<Ronin...do you have an answer to the original question?

The answer is "no"... I cannot say why he does anything, as don't know the ~gentleman~! Now if he'd asked why ~I~ (or you) used this dynamic tenshin, well that would be a different question

If that had been asked, perhaps the vein-popping which some demonstrate (calling it dynamic tension) might perhaps be circus, silly melodrama? Or perhaps it is not the tightening which is the better benefit, but rather the letting go, the UN-contracting which is of fundamental value to the practice? Consider its pathetically easy to be tight, too easy, but how many can be supple without some extraordinary efforts I wonder?!?!?

Dynamic tenshin meaning contraction and uncontracting will generate the adrenal response and trigger the lovely horemones which I propose obviously need to be explored specifically in order to not be overwhelmed by them in intense serious/sudden situations. Not magic, not rocket science I would think, but I am puzzled by those who go over the top doing so and wonder the value of their eye bulging, vein-popping corinary on a stick expression... Is there ~fundamental value~ in what seems excessive demonstration?

Can ~dynamic~ be too much? Your turn...

Well thats clear that one up.....*hears the sound of a drive by*
