“Internal”
martial arts today are more popular than ever, if it is not “internal” it is
not worth practicing, at least that is what large number of people who follow
and practice these arts say. But what internal martial arts really are? What “internal”
really means? Is it really so much better than “external”? There is a myriad of
definitions and seems not that every teacher but every single practitioner has
its own explanation of the matter. To make things even worse, people include mysticism,
religion, obscure theories about nature and human body and in some cases even
magic. Sadly, many practitioners of “internal” arts believe in them but not
actually understand or even seriously practice their arts.
So,
let’s bust few myths and explain what internal arts really are
1. Internal
arts have nothing to do with Qigong ! Qi does not exist, period. How do we know
it doesn’t exist? Simply, science is not able to prove its existence! Someone
may say that science is not advanced enough and it is not able to detect Qi.
While that may be true the main problem is that scientific research requires a solid definition of what Qi is.
From the people who insist on its existence and profess it, science need an in
depth dissertation on its workings from these people. From these we can then
search for testable statements and draw a scientific prediction . The hypothesis must also have alternative explanations that have to
be tested for as well. So, basically, science is unable to test and research
something that has no clear definition, that no one knows what it is, but know
it exist !?!?!?! On the other hand, science did a researched Qi in domain that
actually can be measured and validated. Although Qi cannot be detected the
effects of Qi can be measured. All test conducted in an effort to measure the
effects of Qi failed miserably just as it was the case with magic, “prana”, “bioenergy”
ect. It is impossible to see any effect of Qi, not immediate one for which
whenever scientifically examined, it turns out to be a parlor trick, nor long
term supposed health benefits. Simply, Qi comes from a carefully controlled and
disciplined mind and body under typical psychological and bio-physical
conditions. It is a form of self deception or when we talk about students who
got knocked out with “no touch” attack, their compliance comes from due to
unconscious social pressure, simply they are brainwashed. Qi is a remnant of
the ancient people believes who did not understand how physics, biology, and
medicine really work, so they invented a poetic, shamanistic, religious story
to give the some sense to their world view.
2. Muscle
power is not needed to create force in internal martial art, muscle are not
used in training of application. Some people go even further and claim that too
much muscle are actually bad for practicing nei gong but on the other hand
developing a “pot belly” is beneficial. Again, this is a nonsense. First of all
it is physically impossible to move without muscles, that is their purpose.
Complete relaxation means no movement at all, in order to make any kind of
movement muscles must be involved. “The more relax you are the more power you
can generate” this is often repeated sentence by internal arts teachers but is
it actually true? Different activities engage muscles (and complete body) in a
different way. Repeated activity will condition muscles in certain way which will
develop according to type of conditioning.
For example power lifters have different muscle development from bodybuilders
who again have different muscle development form gymnasts who have different
muscle development from boxers and so on. Same goes for internal martial arts, muscles
are conditioned to for specific kind of movements for specific outcome. In
internal arts muscles are trained to make fast and short contractions to release
energy. More muscles you have, more power you have, of course if muscles are
conditioned for that kind of activity. Human body does not escape laws of
physics and biology and chemistry no matter what someone may believe, there is
no esoteric practice nor religion that will change this fact. No muscles no movement.
What people call “relaxation” is actually specific way of muscle conditioning which
make contraction in order to generate energy.
3. Next
claim is actually a second part of the previous one it says that connecting
tissue is actually the most important in internal arts, tendons and ligaments
are actually where the power is generated and they are pathway for force flow
throughout the body. People believe that somehow connecting tissue can be used
as a form of spring and release the energy just like the real spring and that
is why the muscles are not important and not used. Again, total nonsense. Ligaments
serve as connectors, linking the ends of bones together at a joint. The joints
allow for the performance of simple and complex motions throughout the body,
and ligaments come in a variety of sizes and shapes to support, strengthen and
stabilize the joints. A tendon is a fibrous connective tissue which attaches
muscle to bone. Tendons may also attach muscles to structures such as the
eyeball tendons
aid in the movement of bones by transmitting force from the muscle to the bone.
Tendons aid in a wide range of motion and act to resist pressures; hence, it is
important that they vary in shape and size. Tendons also help absorb
some of the impact muscles take as they spring into action. Ligaments and
tendons are made of dense layered collagen fibers, called fibrous connective
tissue. They also have some elastic fibers that allow them to move, but not so
much that it moves beyond its capacity. As we can see , connective tissue has
very specific purpose and while it is essential in body parts movement as much
as bones and muscles their purpose is not to generate power nor to transmit it
power from part of the body to another . While connecting tissue has some
elasticity, that property is far beyond what internal practitioners believe and
it is physiologically impossible for connecting tissue to generate power, that
is a job of a muscle. While conditioning of connecting tissue helps the “force
flow” it is not as important as it is believed simply because tissue tolerance
for stretching is pretty limited.
So
what is actually going on and what actually internal power is? To understand
that we have to understand a basic processes in human body, especially muscles.
There
are three types of muscules:
1. Cardiac
muscle (myocardium), found only in the heart, is a striated muscle similar in
structure to skeletal muscle but not subject to voluntary control.
2. Smooth
muscle, neither striated in structure nor under voluntary control, is found
within the walls of organs and structures such as the esophagus, stomach,
intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector
pili in the skin (in which it controls erection of body hair).
3. Skeletal
muscle, which is out area of interest in this article striated in structure and
under voluntary control, is anchored by tendons (or by aponeuroses at a few
places) to bone and is used to effect skeletal movement such as locomotion and
to maintain posture. (Though postural control is generally maintained as an
unconscious reflex the muscles responsible also react to conscious control like
non-postural muscles.) An average adult male is made up of 42% of skeletal
muscle and an average adult female is made up of 36% (as a percentage of body
mass). It also has striations unlike smooth muscle. These muscle are formed of
long multinucleate, cylindrical cells called muscle fibers. Skeletal muscle
fibers are grossly divided into two type; slow twitch (type I) and fast twitch
(type II). Type II fibers are further divided into type IIa and type IIb
fibers. Type IIa fibers are intermediate fast twitch fibers and can utilize
both aerobic and anaerobic metabolism for ATP production. Type IIb fibers are
the classic fast twitch fibers. Slow twitch muscle fibers primarily utilize
fatty acid oxidation and contain a high concentration of mitochondria and store
appreciable amounts of oxygen as oxymyoglobin. These two facts are the reason
that slow twitch fibers are red in color. Fast twitch fibers primarily utilize
glucose oxidation to pyruvate for ATP production, contain less mitochondria and
myoglobin than slow twitch fibers, and thus, are white muscle fibers. Because
slow twitch fibers prefer to oxidize fatty acids they are also referred to as
oxidative fibers, whereas fast twitch fibers that utilize glucose are referred
to as glycolytic fibers. Slow twitch fibers are capable of continuous extended
contractions and therefore, do not fatigue quickly. Fast twitch fibers are used
for short rapid bursts of energy and as such fatigue more quickly than slow
twitch fibers.
Now let’s see how muscle actually works.
Generating power is called muscle contraction and it is not just a muscle
shortening as it generates force. There are many different ways that a muscle
can generate force.
1. Concentric
Contractions—Muscle Actively Shortening. When a muscle is activated and
required to lift a load which is less than the maximum tetanic tension it can
generate, the muscle begins to shorten. Contractions that permit the muscle to
shorten are referred to as concentric contractions. An example of a concentric
contraction in the raising of a weight during a bicep curl.
2. Eccentric
Contractions—Muscle Actively Lengthening. During normal activity, muscles are
often active while they are lengthening. Classic examples of this are walking,
when the quadriceps (knee extensors) are active just after heel strike while
the knee flexes, or setting an object down gently
3. Isometric
Contraction—Muscle Actively Held at a Fixed Length. A third type of muscle
contraction, isometric contraction, is one in which the muscle is activated,
but instead of being allowed to lengthen or shorten, it is held at a constant
length. An example of an isometric contraction would be carrying an object in
front of you. The weight of the object would be pulling downward, but your
hands and arms would be opposing the motion with equal force going upwards.
Since your arms are neither raising or lowering, your biceps will be
isometrically contracting.
4. Passive
Stretch—Muscle Passively Lengthening. There is a fourth type of muscle
"contraction" known as passive stretch. As the name implies, the
muscle is being lengthened while in a passive state (i.e. not being stimulated
to contract). An example of this would be the pull one feels in their
hamstrings while touching their toes.
To
fully understand the mechanics of the movement we also have to understand the purpose
of the skeletal system which is the framework of the body, consisting of bones
and other connective tissues, which protects and supports the body tissues and
internal organs. The skeleton can be divided into two
components, the axial skeleton and the appendicular skeleton. The axial
skeleton is formed around the central axis of the body and thus includes the
skull, spine, and ribcage. It protects the brain, spinal cord, heart, lungs,
esophagus and major sense organs like the eyes, ears, nose and tongue. The
appendicular skeleton is related to the limbs and consists of the bones of the
arms and legs, as well as the shoulder and hip girdles. Bones serve a variety
of functions, primary among them being movement. Two bones or cartilages are
held together at a joint through tough connective tissues called ligaments.
Muscles are securely attached to bones through flexible but inelastic
connective tissue called tendons. Muscles, joints, tendons and ligaments are
part of the intricate machinery that allows the movement of different bones.
Human
movement is achieved by a complex and highly coordinated mechanical interaction
between bones, muscles, ligaments and joints within the musculoskeletal system
under the control of the nervous system. Muscles generate tensile forces and
apply moments at joints with short lever arms in order to provide static and
dynamic stability of the body under gravitational and other loads while regularly
performing precise limb control.
This
is basic frame of every human movement.
How to define “internal” and “external” movement? Basic biomechanical
processes for both, ”external “ and “internal” movements are the same so how to
separate them? The difference is in level of biomechanical efficiency for same
type of work. ‘External” can be defined as a usage of local group of muscles to
generate , receive and transform force , it is a movement without competence or in a segmented way, that
will leave certain areas of the body uninvolved in the movement.
On
the other hand “internal” can be defined
as an abilities to move every part of the body in harmony. Using a specific skeletal
alignment with a proper sequence of muscle contraction , “internal” power have
significantly higher level of movement efficiency whit significantly lower
energy consumption. There are many
different ways in which the body is used in this regard but all these methods
share certain common traits explained above.
As
we can see, difference between “internal” and “external” is not in the nature
of the movement and certainly it has nothing to do with esoteric or mythical
powers and energies, but it is a difference in quality of utilized movement or
more precise in the level of energy consumption vs. desired output,
