Force Efficiency in Application

  When performing a defensive motion/technique, the student should maintain that the motion(s) remain within the most optimal positioning for their application. The majority of students only concern themselves with the final portion of a utilized motion. Every application has fundamental requirements for it to be successful. “Fundamental” implies that those subjects are required for every attempted application.

  Understanding human Kinesiology (the study of anatomical motion) will aid the student in their ability to manipulate an aggressor during a confrontation. That ability is (further) exemplified through the student's recognition of “Force Efficiency”. In the simplest terms, force efficiency describes the most efficient use of body motion while performing a chosen action, that produces the greatest effect. Though doing so by other means may do so (slightly) more quickly, those methods often produce more opportunity for “counter-measures” to be utilized against them, and/or result in less effective applications. The human body is designed to operate in specific ways. Though other means of achieving those motions exist, that doesn't mean the body is designed to motion (efficiently) in those manners.

  If a student is only focusing on the individual limbs motion, they are ignoring those fundamentals. When students are initially shown a motion (be it for the arms, legs or a movement/position), that instruction is initially focused upon the individual portions of that movement. Once that portion is understood by the student, the instruction is widened to include the remainder of the body.

  For the beginning student, their instruction is initially directed to the “stances”. Stances are positions that are intended to provide a stable “base” for (which ever) arm/leg motion it is that they will be attempting to perform. Each of the shown positions are intended to provide that stability under given circumstances.

  The majority of force efficiency principles deal with maintaining the alignment of the shoulders and the hips (with one another). This alignment is intended to provide the greatest balance (and thereby ability to perform) the techniques that utilize the arm's and/or legs. Maintaining that alignment will cause the student to always consider the Upper/Lower body codependency (ka han shin/jo han shin).

  When that alignment is altered (from being “square” between the two), the person will be “off-balance” (and any technique performed will not be done in the most efficient manner). Numerous instructors/systems teach their students to motion the shoulders/hips “into” the performed action. Doing so, may add (slightly) to the applied body-weight transfer (of “mass”), but the cost of the increased instability (in doing so) does not justify that supposed increase.

  Many students are of the belief, that doing so will “make” their motion be more powerful. The gain (in transferred momentum) is only minimal (disregarding the obvious fact, that they are decreasing their own stability when doing so). The resultant lose of stability (whether the delivered application is successful or not) does not justify any (presumed) “gain” of transferred momentum. It equates to being an “over-commitment” (for a delivered application), making the student (then become) off-balance and/or highly susceptible to counter-measures (being applied by the opponent). If/when a technique/application is dependent upon strength/power (to begin with), that motion has limited (if any) value.

  Though numerous defensive systems (attempt to) teach those positions/motions via the practice of “sparring”, Oyata taught that doing so (additionally) “taught” the student to wait until the aggressor began their assault (and only then, utilize those positions), before beginning their defensive responses. He (Oyata) demonstrated that by doing so, the student will have (unnecessarily) delayed that defensive response. He additionally demonstrated that many of the (popularly) taught methods of performing those actions are flawed (in the manner they are commonly taught). The majority of those differences are often subtle, but are each done for specific reasons.

  Those types of applications are for the young, strong, inexperienced student. Will they work? Yes,...sometimes. There are too many reasons why they (more likely) won't though. The majority are intended to make the user “feel” (as if) they are being more “powerful” in the execution of those motions. They provide the illusion that the student is progressing in what they are studying.

  Oyata did not endorse those methodology's (within his instruction). He taught that the student should understand what does, and doesn't elicit (actual) results. Though he didn't actually refer to what is being taught as “Force Efficiency” (as this is the name that “we” utilize for it), he taught natural body motion.

  Force Efficiency consists of natural body motion in conjunction with the application of (entire) body-motion/use. That includes standing, walking, limb motion and any “body” related motion involved in the application of defensive actions.

Recognition of Shoulder/Hip Alignment (IE. “Force Efficiency”)

 When one is standing naturally, the arm's will hang loosely by the sides and the shoulder's are relaxed. This is (commonly) recognized as being a “Natural” stance. When you note the position taken by the feet, they are (usually) splayed slightly outward, and generally positioned at shoulder-width. It is this (basic) position that a person assumes when standing. They may (or may not) have something in their hands, but the position/stance is common. This was the stance that Oyata taught students to practice (and perform) the (taught) defensive motions from.

  The weight of the body should be evenly distributed between both feet. If/when the weight is toward one side, it should be (blatantly) obvious (to the student). This constituted one of Oyata's first lessons (to his students). When an opponent's body-weight is concentrated to one side, that person is only able to perform particular actions (without any additional body-weight being shifted, in order to be included in those actions). To do otherwise required additional (body) motion(s) to be included as well. If that motion was an “arm” motion, the shoulder's (may) require adjustment/change, if the motion was for their legs, it would have to be done with the leg not bearing the user's body-weight. The position of the head would (virtually) never raise, but it may rotate (or more likely drop), but (if/when performing an action) would likely face towards the intended action.

  Any of those possibilities could (initially) be detected through the observance of the person's shoulder's. To perform any of those motions, the shoulder's will display some level of motion. This implied that observance of an opponent's shoulder's was (initially) a student's priority (defensively).

  The use of the arm's (by an opponent, or by the student) implied that the performed motion would (likely) occur within the area between the user's shoulder width. For that reason, Oyata taught that one's initial defensive motion(s), include the repositioning of one's body to be “off-center” (to one side or the other). This could be done to either side (depending on how the student trained, but the direction was (actually) unimportant (defensively).

  As the student performed this repositioning, their arm's would be motioning in (practiced) directions to provide a defense against any motions performed by the aggressor. Through that repositioning, any of the aggressor's arm/leg motions (leg or hand/arm strikes) could be negated, and provide for the user's own Hand/Leg responses.

  It is (virtually) impossible to (exactly) know “what” an aggressor is going to do (as their aggressive action). It is possible to limit those options though. When the student begins (by standing “square” and evenly balanced) they are then able to motion to either (Left/Right) direction (as the situation develops/proceeds). The student should of (already) been aware of what actions were possible (via the aggressor's stance/positioning) and thereby have already chosen a direction for their own (initial) defensive motion.

  Oyata's defensive method was intended to address an aggressor's initial action (“attack”) and follow it with motions that would neutralize any continuance of those attempts. For that reason, the practice of “sparring” served no purpose (with what/how he taught that purpose to be achieved). 

Defensive Positioning

 

  Whether one chooses to (or “winds up”) being on the “inside” or “outside” of the aggressor's arms, is a widely debated subject. It should really be irrelevant (defensively). Either position can be utilized to respond to an opponent's aggressive action and/or allow for a defensive response. Both positions should be addressed during one's practice. The more important factor (in either instance) is that the student be aligned for their own force efficient use of their applications/techniques.

  Many systems stress that a student should (always?) be located to the outer-side of an aggressor's arms. Though having some (obvious) disadvantages, if/when being located on the “inside” (of the aggressor's arm's), it is not (really) that bad of a location. The most popular argument made against this positioning, is that the aggressor can strike the defender with either of their arms. What (generally) isn't pointed out, is that the defender has twice the number of vulnerable targets available to them (upon the aggressor).

  The majority of vulnerable locations are located upon “medial” (anatomical) locations on the human body. These locations that are (generally) facing towards the opponent's center-line (and are thus naturally “protected” from strikes when one is positioned to the “outside” of the width of the person's shoulder's). Being on the “inside” also places each of, (generally) the opponent's limbs outside of the defender's (shoulder-width). This (at least initially) provides the defender the opportunity to take advantage of that positioning (while protecting their own locations of vulnerability).

  When positioned to the “outside”, the defender commonly has to negate (through moving) the opponent's limbs to reach those “points” of vulnerability. Many of the (most) vulnerable locations are on the aggressor's arm's. These can more easily be accessed if/when the defender is located between the aggressor's shoulder-width (IE. When on the “inside”).

  People generally recognize that when you are positioned to the outside (of the opponent's shoulder width), they will be inclined to utilize some manor of “force” (in order to apply any manor of technique). That force, may be through injuring the opponent (via delivered impacts), or through moving the opponent's limbs (in order to apply that force). Oyata taught that one should utilize those locations that are (immediately) available (regardless of one's present location). Though not necessarily being individually “devastating”, cumulatively, they caused the aggressor to become (if not less aggressive) less effective in any continued attempts.

  Force Efficiency plays a major role in one's ability to accomplish this. Disrupting an opponent's Force Efficiency is an important factor/purpose for any applied technique. If/when someone is “off-balance”, their Force Efficiency is (greatly) reduced. This applies to (both) delivered, and received technique applications.

  The student should focus on applying this principle with all performed actions (Defensive as well as Offensive), through their occurring within the distance between the width of their own shoulder's. Those motions attempted beyond those limitations will result in (obviously) reduced success. This is easily shown by the student performing a “punch” (using only the motion of the arm) directly in front of themselves, then to the side. The differences in the level of effectiveness (between the two) is obvious.

  The same situation exists (though more obviously) when attempting to utilize the legs beyond the direction(s) of directly forward and/or rearward (though downward is a more accurate description of direction for a “rear” kick). So-called (forward) “round” kicks, entail the leg (and body) being rotated for their delivery of a “round” kick. “Rearward” round-kicks, are referred to as being “hook-kicks”. The “extension” kicks, are almost all (anatomically) “downward”(directed) kicks (more accurately being “thrusts”).

  Force Efficiency should be recognized (and utilized) in every limb action attempted/performed. Any motion that attempts to operate beyond those limitations will (itself) be limited in it's effectiveness and applicability.

  Our instruction of Force Efficiency is began with the limb's “Range of Motion” (R.O.M.). That knowledge is directly utilized with (both) “striking” and “manipulation” (“Tuite”) applications. It is shown with each of the instructed techniques (mentioned previously). Many of the included principles (of Force Efficiency) are naturally recognized (though not always understood, or utilized) in a students application of the provided instruction. Developing the student's awareness of those relevancy's, is the reason and purpose for having an instructor (regardless of the “system” being taught).
