Knee Release Progress Report – Memorial Day 2001
Spending the weekend with a bad knee
strain, I've been thinking on my research into the knee release
this past week. Apparently I've stumbled on something which has been
relatively undocumented. Such that those who address this haven't
been going out of their way to let the rest of us in on it.
Not that I find this surprising, for I
believe most of the important areas of martial study are
undocumented for public consumption. Frankly this is what I live for, to
try and gain a new layer of understanding gaining a little more
depth into my art.
I've been discussing this on my own
discussion group, Bunkai Unlimited, and also with the
Koshi-People Discussion Group. I think it might be helpful to summarize the
content of this research to date.
First off I wish to state I'm keeping
this focused on the one aspect of the knee release. Frankly in
all of these studies, there are many other valuable items to
consider and I expect we'll continue to discuss them as this study
progresses, but I suggest them as spin off discussions at this time. I also
believe we may work up a better set of terminology than knee release
as we progress, be it Japanese or something more descriptive in
English, too.
Initilization
of the Process
March 2001, Sherman Harrill at a
clinic in Rhode Island, made some general comments regarding use of the
knees to generate power. He also presented an interesting
application for a section of kata Wansu.
In April when I was working on that
Bunkai, I discovered by applying a knee release, I was rotating myself
naturally into the technique without body shifting. I then shared
my findings with the Bunkai group.
Contributions
Rich Boyden discussed how an aikijutsu
instructor demonstrated knee relaxing punching for a relaxed
effortless punch. He discussed how the knee release ("yurumu")
action was also used to reverse a shiho nage, as well as how Oyata
Sensei used this motion to crank up a joint lock. Rich also suggested
similar technique may be viewed in Bob Orlando's "Indonesian
Fighting Fundamentials" (Panther Video).
Hank Prohm, also suggested the knee
release was being used as a `Force Multiplier'.
Another friend who practices Daito Ryu
and a related system of kenjutsu, suggests that they spend 90%
of their time working on this. That Wado Ryu's founder Ostsuka
Hironori in his book `Wado-Ryu Karate' show shift as part
of Pinan #1 when he says "Sink Your Weight". He also suggested
in Daito Ryu they also use a unique body alignment with the sinking knees
to generate more shocking power in their strikes.
Joe Swift then threw out a translation
of a book by Aragaki Kiyoshi "Okinawa Budo Karate No
Gokui" where he based the book on the "Kuden" (oral
transmission) that he received on Okinwan Karate as a young man. He discussed
"Hiza wo Kuku" (releasing the knees) to generate power while moving
instead of pushing off of the back foot.
Will Bill Johnson (from Koshi People)
made worthy suggestions about practicing slowly and safely, as the
counter and counter of counter potential can quickly drop your uke.
He also suggested the term ofr the spiraling descending power is
`uzimaki', and the application of the knee release to
locks was `jugoku otoshi (drop to hell) where the lock is applied in
conjunction with a weight displacement and the power is applied
right at point of broken balance.
George Donahue (Kyoshi People)
discussed the need for correct alignment to avoid self injury, and
increasing the force generated. He also suggests watching Oshiro
Toshihiro in his "Uchanidi" video tapes.
My current research suggests the
following, too.
1. I've been long aware long term
practice allows the body to naturally relax in a technique, causing
the center to drop and the power generated will increase. Frankly
I'm stunned it never occurred to me that you can assist
this development with the knee release, too. 2. Ernie Rothrock, teaching my
students a very small piece of the Eagle Claw Principles last year
stressed dropping the knees when applying the eagle claw locks.
Unfortunately that went no further in my/our thinking at that time. 3. The use of knee release in our kata
will be a further source of study as time progresses. 4. The only documentation I seem to
have found comes from Gozo Shioda's "Total Aikido",
where he describes something like the knee bending when generating
a move forward. Not necessarily the same as we've been
discussing, but worthy of further study. 5. The fact I haven't found such
documentation regarding Judo and Baguazhang, arts I suspect as well
as Aikido which must use this principal too, does not mean it is not
present. This is an area for further study. 6. I know this is present in my Tai
Chi studies, too. I've been unable to locate similar references in
my tai chi library, but I'm still searching here too. In fact,
from open to close, the knee release is present 100% of the time,
and it is how tai chi movement generates. Pushing Hands drills stress
this in correct power generation and neutralization
practice.
Summation of Knee Release Options for
Study
My group then took these suggestions
and ran with it. A simple synopsis would be we are further
investigating:
1. How the knee release is used to
generate more offensive power. 2. How the use of the knee release
generates torso rotation to generate offensive power. 3. How the use of the knee release
generates torso rotation to generate defensive placement. 4. How the use of the knee release
becomes a force multiplier to crank up a lock or takedown. 5. How the use of the knee release can
counter strikes, locks and takedowns. 6. How the use of the knee release can
counter counters.
One thing I have noticed, finding my
way through this body of material, its easy to become a kid
loose in a candy store. Especially in the defensive counter
and counter-counter knee release we're most likely dropping too far
(perhaps 2 or 3 inches), having fun with this knowledge.
I surmise as we advance this study, we
will find a lesser drop will suffice, and allow us to move into our
follow-up faster.
We are beginning at looking at an
Aikido Linking Drill we use to practice various Aikido locks, also as
an Aikido countering exercise. We are working at softly
applying and countering these techniques, learning how to feel the
correct drop for countering application.
I expect as we progress we will study
kata Bunkai along with the potential of using the knee release as
a potential counter of same.
I find it interesting how little has
been written describing countering locks. Dr. Yang did some of
this in his Chin Na Instructors Manual, and there is an
Aikido book describing Tomari Aikido (purple cover) which goes into
explicit countering of the techniques taught (perhaps consistent
with Tomari's aikido free sparring). But as shown, the release
of the knee does not appear to be the principle they are using.
It seems to me we're working with a
fundamental underlying principle of the arts.
A target (offensive or defensive)
presents a sphere of opportunity to move against. Any technique is most
effective perhaps on one plane that touches/intersects that sphere.
Defensively if you release the knees you drop yourself out of the
attackers plane of opportunity, making their efforts less effective.
Offensively to make the available plane work for you, you need
to 1) be quicker on the attack to effectuate your movement before
they can respond or 2) you need to be able to adjust yourself (through
your own counter knee release) to maintain that plane of opportunity as
their sphere changes location.
Now isn't that a mouthful.
But, it might explain why some
Okinawan's I've seen perform kata do so incredibly quickly. The
issue is the same with striking, and speed is of fundamental
importance.
Sure I'm borrowing on the concept of
the Dynamic Sphere of Westbrook and Ratti, but I believe
this is a different manner than which they use it.
The further I look the larger this
topic becomes. I look forward in you joining the research and helping
define this more fully in the future.
"Hiza wo Nuku" (Releasing
the Knees) Joe Swift translation
Aragaki Sensei says that modern karate
movement, especially the mainland Japanese styles, use the knees
and legs incorrectly when moving. He states that most use the back
leg to "kick" or push off the ground in an effort to move forward.
This is akin to the human action of running or jumping.
Old Okinawa karate, however, does not do
this, he says. Instead, they "release the knee" (i.e. relax
the knee) of the front leg. When one does this, one will naturally fall
forward. In order to compensate this falling momentum, the back leg
naturally steps forward, and viola, you have the forward stepping
motion. The idea is to use the natural gravitational effects to
"pull" you forward. This is akin to our natural everyday walking style. He
goes on to say that one can also use this idea to move backwards, on
angles, and even side to side (as in Naifuanchi). One of the
advantages of this movement principle is quicker movement with less
telegraphing.
Arakaki Seishō (新垣世璋, 1840–1918) was a prominent Okinawan
martial arts master who influenced the development of
several major karate styles.[1][2][3] He was known by many other names, including Aragaki Tsuji Pechin Seisho.[4]
Arakaki was famous for teaching the kata (patterns) Unshu, Seisan, Shihohai, Sōchin, Niseishi, and Sanchin (which were later incorporated into different
styles of karate), and weapons kata Arakaki-no-kun, Arakaki-no-sai, and
Sesoku-no-kun.[3]
Some consider Chitō-ryū the closest existing style to Arakaki's
martial arts,[3] while others have noted
that Arakaki's descendants are mostly involved with Gōjū-ryū.[1]
