The application of the instructed
techniques are commonly utilized upon (various) anatomical locations
that will provide the desired responses. Those locations are commonly
recognized as being "atemi" (or even kyusho)
point's/locations. These locations (commonly) amount to being
(vulnerable) physical locations that are readily accessible for being
struck and/or manipulated. These locations can be tendons,muscles
or (vulnerable)
nerves.The use
of these locations requires the understanding of "what"
qualifies that location as being vulnerable (for
use in a defensive situation).
This
can (often) only amount to being "available" (for that
use). This requires that the student understand where,
when, how
those locations are (both) located and
vunerable to/for
(defensive) use.
These locations are
identified (to our students) during their general instruction of the
shown motions and applications. The student must (obviously) be aware
of the presense and location of those nerves and the location of the
relevent muscles and tendons. We (initially) address the "major/main"
muscles and nerves of the area(s) of technique application/use.
These begin with
the student's knowledge of:
Major Arm muscles:
Of the Upper-Arm:
Biceps
Triceps
Of the Forearm:
(finger/wrist):Extensor's
Flexor's
Arm Nerves: Ulnar Nerve
Medial Nerve
Radial Nerve
All of the nerves within the arm emanate from the brachial plexus (located in the upper lateral area
of the neck/chest area for the relevant arm). Where those nerves
enter the arm (within the “arm pit”) they continue down the arm
into the Elbow then will separate and continue into the hand. The
Radial nerve “circles” the upper-arm and travels down to the
Elbow, then follows the "thumb" side of the arm. The Ulnar
and Medial nerve remain in the medial side of the upper-arm until
they reach the elbow. The Medial and Ulnar nerve inter the
Elbow-joint (deep) and exit the elbow (entering the forearm) into the
anterior side of the forearm. These nerves (loosely) follow the Ulnar bone to the wrist. These nerves are superficially located at the
wrist (prior to entering the hand) along the anterior side.
The Upper Leg Muscles:
Frontal: Quadracept Muscles
Posterior: Hamstring Muscles
The (Upper) Leg Nerves:
Medial: Femoral Triangle (cluster of
nerves within the medial thigh region)
Radial: Psciatic nerve: Follows the
side of the leg medially (Branches and becomes the common
Paroneal, goes above and around the knee,
The Lower Leg Muscles: Mainly consist
of the posterior calf muscles
The Lower Leg Nerves:The Tibial
nerve continues towards the foot, under the calf muscles.
Strikes to the legs (generally) produce
one (or more) “general” responses, the “collaps” of the knee
or the rotation of that leg (and therefor the “Hip's/Torso). Either
of these actions can be augmented with the “follow-through” of
the actions. The lateral rotation of the knee can additionally cause
excessive (if not damaging) pressure upon the ankle of the
effected leg.
One should note, that the commonly
struck areas of the “diametrically” located arm, has similarly
located “points/locations”, as are present upon the respective
leg (the left leg, in relation to the Right arm etc.).
The greatest misconception of striking
a muscle, is that it has be either “flexed” (or "relaxed")
when struck. The Tori will only have limited amount
of control in that ability (regarding the state of that
muscle), so it becomes important to understand how the muscle/tendon
should be struck in either of those situations. When it is
relaxed (comparitively) it will produce a greater reaction
when the strike is made upon the muscle body. When the muscle
is flexed, it is easier to achieve a reaction by striking the
tendon's (of that muscle). (Most of the misconceptions in this
regard, are based on not understanding the actions of the
muscles/tendons when the limb's are beihg utilized).
When the muscle is relaxed, it is more
productive to strike the muscle body.
When the muscle is being utilized, the muscles
tendon's are easier to
achieve a desirable reaction (and vice-versa).
The area directly surrounding a
“joint”, contains mainly tendon's. The muscle “bodies”
are mainly located upon the locallized limb (mid-way) between
those joints. Whether a muscle is flexed or relaxed is dependent upon
the action being performed with the relevant limb.
The leg's muscles, are always
being utilized (when the subject is standing), so one's choice
of targeting is dependent upon upon the subjects positioning and/or
action (at the time of an impact). Direct Strikes made upon a muscle
“body”, need to be done with a higher level of (penetration)
"power" to achieve an effective result (as the muscle will
commonly be flexed). A strike to the tendons (of that same
struck muscle) need to be done across/perpenticular to those tendons.
The majority of the instructed strikes,
attempt to take advantage of the “2 car” principle (with an
attempted strike). This either includes the opponent's motion, or the
addition of the Tori's second hand. This is also refferred to as
being the “cutting board” principle (of application).
The degree of response/reaction (by the
Uke) is gauged by the degree of movement allowed (or reduced) by the
Tori during the techniques application. Strikes are applied with
either direct or perpendicular motion upon the struck tendons/muscles
(depending on which is being struck).
The correct inclusion of one's body
weight, is effected by one's use/motion of their entire body, This is
accomplished via the Tori's (body) rotation and raising/lowering of
their body (during the performed motion). This rotation is commonly
achieved through one's motioning of the knee's, hip's and shoulder's
during those actions. Stances are often (mistakenly) considered to be
secondary to an attempted action. Stances are another piece of
the primary application. The positioning achieved by the lower
body determines what can (effectively) be achieved with the upper
body/arm's.
Forward and Rearward (body) motion will
additionally effect the subject's (probable) limb positioning. Using
the "Walking" example/model, limb position/use (as well as
vunerabilitys) can be established prior to the subjects
use of those limbs (regardless of whether the subject is moving or
stationary when the motion is being performed).
Those individual's who (attempt to) use
the "TCM" theory's, use that information to convey a
similar understanding of these principles (of motion). We feel
that study is unneccessarily confusing (if not missleading)
and includes unproven (if not incorrect) concepts and ideas
that only confuse the student.
Oyata spurned those ideas and would
become (very) hostile if they were brought up. He wanted
nothing to do with (any) individual's that promoted that study. He
believed it to be a distracting waste of time.
When limb motion was described, it was
related in an obvious (if not simplistic) and relatable
manner. Oyata may have not known the ("name" of the exact)
muscle being struck (or utilized), but he could describe all of
the possible actions of that muscle (and how it did/didn't work).
That knowledge didn't come from a book (nor from "scholarly"
study), his knowledge was gained through his (direct) research of
technique use and the reactions from that use.
What we've found (through the
instruction of our student's) is that the greater the student's
understanding of basic "body-motion", the more
easily they will be able to apply the instructed applications. The
more obvious (if not simplistic) that understanding is, the
more applicable it becomes for the student. For those
student's that wish to explore that understanding to a higher degree,
the material is readily available through the vast amount of
medical texts available in any public library (everywhere).
Each of the previously described actions can be described (with
greater detail) within those texts (often providing the research
parameters that established those conclusions).
The most important factor (for the
student to understand), is that an individual muscle, tendon or nerve
will not (if ever) only
cause/create reactions that are located at the affected
location (Ka Han Shin-Ja Han Shin).
The Use of these locations (for
defensive applications) will be directly proportional to the
student's understanding of the location (and general use) of the
commonly used muscles in conjunction with the limb's R.O.M. (during
that limb's use).
