I continually receive inquiry's into our use of the term "Force Efficiency".
Force
efficiency refers to the efficient application of limb, body motion
and weight use during a technique application. Though individual limb
motion is often addressed, every motion involved with that
application needs to be utilized is shown as being an entire
body
motion. Because of how
many
of those factors are being utilized, students are inclined to focus
(only) on the individual limb's use (alone) during their practice of
those motions.
Regardless
of whether it is a strike, a push, a kick or a grab, the student
should utilize the entire body's weight and motion (within a
controlled perimeter) in the performance of the individual action.
This implies that the student provides the least amount of
vulnerability while doing so. Those motions should also be performed
as naturally
as possible. Those motions that create (or mandate) exaggerated
motion, are often being performed incorrectly
(and thereby creating vulnerabilities within those actions).
A
large percentage of Force Efficiency is (simply) performing those
motions in the most natural
manner possible. Though (seemingly) being a simple rule, beginning
students will (often) exaggerate a limb's (or the torso's)
motion/use. This is commonly done in order to utilize (extra?)
momentum/force with the motion (thereby “muscling” the
technique/application).
To
properly utilize those factors, the student must first understand the
(natural) range-of-motion (R.O.M.) for both the body, and for the
individual limbs. A large percentage of a students tendency to
exaggerate a motion, comes from not using their entire
body for/with the intended action.
When
delivering a “strike” (or a grab, or a push), one
rarely utilizes only the involved limb to do so. Body weight
is an integral piece of the efficient delivery/use of that
action. To do so in any “other” manner, is to imply the use of
one's muscular strength (alone). This can/will “work”, as long as
the opponent is smaller/weaker (and/or less knowledgeable) than one's
self. It is also less efficient.
Although
the arm's can (obviously) motion beyond
the width of the shoulders, this should not imply that any action
performed beyond that range can be done effectively. Those actions
that are done to the areas to either side (beyond the width of the
shoulders) will be noticeably weaker. This includes those motions
that are performed in those “outward” directions as well.
This
is most readily recognized with the manner that the “outside block”
is commonly taught (by numerous systems). When performed as a
sideways
swing
the
motion is no better (or effective) than a (standard) “parry”. The
arm is simply not intended (nor designed) to be utilized in that
manner.
The
arm (via the elbow/shoulder) is intended
to
(either) “flex” or “extend”. Though it can
(obviously)
rotate far enough to do so, doing so is neither the most efficient,
nor effective use of that limb (in regards to the forearm as an
impactive
technique
application).
To
convey that point, Oyata would state that an “inside” and
“outside” forearm strike (“block”) were performed using the
same arm motion (with
no differences in the arm's motion between the two). The difference,
was in the user's body motion.
By
making that motion a (forward) extension, one
needed to only rotate the torso/body accordingly (to become either
inside/outside). The (basic) motion remained the same regardless.
This (further) illustrated the entire body
application of the instructed (in this case,
the arm) motion.
Force
Efficiency does not only imply delivered
force/momentum,
it (additionally) refers to one's own stability
when
delivering that force/momentum. Though one can obviously rotate their
shoulder forward to achieve another “couple” of inches of
striking
range,
most
realize
that the potential for being placed off-balance
is
(usually) too great to risk doing so (although that doesn't stop
numerous people from doing so anyhow).
The
Instruction of Force Efficiency can (initially) be summarized via
shoulder/hip alignment. If/when these are not in alignment
(rotationally), the body is being placed “off-balance” (and is
more
susceptible to external
influence)
as well as being less effective at the delivery of one's own
force/momentum.
Oyata
repeatedly taught (and reminded) us to “study our own body” when
seeking answers to our (numerous) questions. In this case, Until you
understand how (and why) your own body maintains stability, it will
be more difficult (for you)
to
recognize how to destabilize
an
opponent's body.
Force

and weight use during a technique application. Though individual limb
motion is often addressed, every motion involved with that

to (only) focus on the individual limb's use (alone) during their
practice of those motions.
Regardless
of whether it is a strike, a push, a kick or a grab, the student
should utilize the entire
body's weight (within a controlled perimeter) in the performance of
the individual action. This implies the least vulnerability (to
“countering” techniques) being attempted while doing so. Those
motions should also be performed as naturally
as possible. Those motions that create (or mandate) exaggerated
motion, are often being performed incorrectly (and are thereby
creating vulnerabilities within those uses).
The
use of Force Efficiency is (simply) performing those motions in the
most natural manner. Though (seemingly) being a simple rule,

This can/will “work”, as long as the opponent is smaller/weaker
(and/or less knowledgeable) than one's self. More importantly, It is
less
efficient.
Although
the arm's can (obviously) motion beyond
the width of the shoulders, this should not imply that any action
performed beyond that range can be done effectively.
Those actions that are done to the areas (to either side) beyond the
width of the shoulders will be noticeably weaker.

directions as well.

A
large portion (though obviously, not all)
of Force Efficiency instruction, can be summarized via shoulder/hip
alignment. If/when these are not in alignment (rotationally), the
body is commonly “off-balance” (and thereby becomes

influence)
as well as being less effective at the maintaining of one's own
stability.
“Ka
han shin, Jo han shin” (Upper
body
influences Lower
body)
was a saying that Oyata (constantly) referenced when describing
technique application. This (saying) also implied that Lower
influences
Upper,
Left
(body
motion) influences Right,
and Forward
influences
Rearward
(etc.).
Oyata was attempting to expand our perceptions
and
understanding of how (and why) motions/techniques were effected by
the entire
user's
body. This is initially demonstrated to students through the
instruction of stances
(and
exampled
in
his instruction of Seisan kata).
Oyata
repeatedly taught (and reminded) us to “study our own
body”
when seeking answers to our (numerous) questions. In this case, Until
you understand how (and why) your own
body
maintains It's (own) stability, it will be more difficult (for you)
to
recognize how to destabilize
an
opponent's body.
The
understanding of Force Efficiency is not “how hard one can strike”,
it is the most efficient utilization of one's ability to apply the
full potential of their available force/momentum during a
technique's/motion's application. By doing so, the student will no
longer be dependent upon muscular
strength
(within
those technique applications).
