Proprioception is the sense that informs the body of the
position of the muscles, is the ability to sense the relative position of
adjacent body parts. Proprioception regulates the direction and range of motion
enables automatic reactions and responses involved in the development of body
image and its relationship with space, supporting the planned motor action.
Other functions in acting with more autonomy are control balance, coordination
of both sides of the body, maintaining the alert level of the nervous system
and influence on emotional development and behavior.
This definition comes from the Wikipedia article
proprioception in Spanish. Introducing defined as karate affect the impact or
damage to the mechanisms that inform the body position in space.
By extension all karate techniques performed, if they are
applied with sufficient energy, timing and location, a perceptible decline in
the opponent of his own conception of space. It is simpler words, it knocks
him. There are parts of the body that are most likely to do this, for example
the head, the position of the vestibular canals and innervation. But
specifically in this article, we will see how knee affects their relationship
with body balance.
The human knee has a variety of tendons, synovial chambers,
and bones that make it particularly sensitive to sports injuries, including
martial, and that makes a real target when attacking an opponent and leave
unused.
To do this, karate is available, coded karate kata, a series
of techniques that are listed below:
Sanseru in kata
(Goju-ryu and Shito-ryu), are performed in four directions kick call
fumikomi-geri, specifically aimed at the knee.
Also in Sanseru
kata (Goju-ryu and Shito-ryu), particularly in the first kata techniques, with
a twist blow to the knee area in order to rotate the leg and unbalance the
opponent is done.
In Bo kata become
atemis or shock which are aimed at low or gedan, aimed at the knee or ankle
failing opponent, which will cause his downfall injured or lack of mobility.
Why attack the opponent's knee?
The knee, like all the human body and especially the joints,
has several elements that make it particularly sensitive to injury or attack:
It has
mechanoreceptors that act as transducers that inform the brain of the position
of the muscles, tension and relaxation, in short conception of how the body is
located in space.
Tendons are
located on the same a number of important points, such as Stomach 34, Stomach
36, Liver 8 and acupuncture Gallbladder 34. All these points refer to the
mobility of the knee to be located in or near tendons .
It is highly
innervated when passing packages nerves leading position signals other body
part rich in mechanoreceptors, as the ankle, another objective Martial attacks
made in Bo.
How to make a correct fumikomi-geri?
From my personal experience, after passing through the
Shito-ryu style Goju-ryu, I can say that the process that created more correct
would be:
Start from an
anatomically stable position as moto-dachi or sanchin-dachi. I do not advise
the zenkutsu-dachi because it is too low.
With arms on
guard, we can raise the leg until the knee is the closest to waist level.
Attacking the foot it must be turned into the body to properly taut.
Lower leg,
attacking foot (always tensioned reatrído inwardly protruding external heel
area) to the knee, in the joint, on its inner or outer side. Failing that they
can attack immediately lower calf areas. This process should be accompanied by
a slight discharge from your body down in the moment of impact, perhaps most
difficult to achieve. Caution: Do not tilt the trunk backward in carrying the
tecnique because kinetic energy division that entails.
Roll back leg to
its elevated position with the knee at the same level as the waist.
Lower the leg or
reverse the playback to a safe position.
The effects are achieved by a vigorous application of a
force of 20Kp with the leg, which added weight defender, cause the opponent's
knee bend thereby damaging tendons and mechanoreceptors in addition to the
joint force. This achieves that the opponent sees his conscience impaired
balance or proprioception, falling down or being diminished balance.
An even stronger and violent application might break the
tendons and cause the output of synovial fluid out of the capsules which
enclose it for normal operation of the knee.
From this lecture I advise the responsible practice of
martial arts without damaging the opponent and teammate and always respecting.
Respect and love of neighbor should be, and are, more important than the proper
execution of the techniques.
