Abstract
If its pain you seek, then you have come to the right
place. Human beings contain billions of neurons, each with a specific job. The
concept of pain is really defined by recruition-or rather spatial summation.
Sensory neurons are able to relay signals of discomfort to the central nervous
system. If the level of discomfort is minute, then only a few of these
electrically specialized cells are stimulated to threshold. The higher the
disruption, the more are stimulated. Such a signal to the normal bystander will
cause termination of the present activity. Bodybuilders interpret this
differently however. Rather then stop, we step it up to the next level, so that
our ability to recruit sensory neurons is as great as our ability to recruit
muscle fibers.
No More
Comfort
Relief is another term that must be clarified. Websters
defines it as the removal of something oppressive, painful, or distressing. Why
is this concept important you ask? Because I intend on eliminating it
completely. The following methods are devoid of any comfort. In fact, I have
none to give. But I will say this, you will grow, which is why you entered
hyperplasia magazine in the first place.
Tension
Under The Microscope
When
devising a plan of attack, one must take each aspect of the opposition into
mind. This is our aim, and we begin by analyzing the concept of tension.
While performing
the bench press, the force which your contracting muscles exert against a
barbell is defined as tension, where as the force which is exerted against the
muscle, by the barbell is called the load.
Quote
Biomechanics
And Sport An Introductory Viewpoint
From the above quote we can conclude that
tension and load are opposing forces. I would also add that contraction can be
defined as the actual tension that is produced as myosin thick filaments bind to
actin binding sites. If you have not yet read my articles on this subject I
will briefly explain. A muscle is made up of long cylindrical units called
muscle fibers. These are made up of units capable of contracting. In its
simplest form, these units are called thick and thin filaments. Thick filaments
can bind to thin filaments and form tension. Think of it this way. If you pick
up a dumbbell, your hand binds to its shaft, if this did not occur then the
dumbbell would fall to the ground. The principle is similar, when a load, such
as a barbell is in your hand, you need to be able to support that load. So,
myosin thick filaments bind to actin thin filaments, producing an opposing
force. For further discussion on this topic I would recommend reading the
anatomy of a muscle, and my article on the
all or none principle.
What needs to be realized
is this: The more myosin heads that bind with actin, the more tension is built
up. Just like in a tug of war, the more people at the end of a rope, the
greater the force on that end.
My main concern in this
article however is to define a variety of contractions. Again, this is defined
as the occurrence of tension building properties within a muscle.
The best way to understand varying contractions is to compare and contrast
muscles in a laboratory environment. In such a situation, there are two ways to
test muscular contraction. When a muscle is detached from the body, we call
this an in vitro protocol. Such a set up is extremely useful, as it provides
extremely stable conditions, devoid of joints, and unnecessary angles. When a
muscle remains in the body, such as is performed on human experimentation, the
protocol is performed in vivo( in life ).
By comparing and
contrasting the two, you will grasp in much greater depth exactly what is
occurring while lifting a weight, and in addition how to manipulate these
physiological parameters to reap maximum stimulatory effects( i.e. heightened
growth ).
Isotonic Vs. Dynamic Contraction
Isotonic Contraction - In
Vitro, a muscle group can be clamped at both ends, and thus controlled. For
example, if you took the biceps brachii and were able to clamp it at the
top, so that it hung in the air. Then following this, you attached a load to
its bottom, you would create a clean, up and down atmosphere in which the muscle
could contract.
In these optimal
conditions, you could electrically stimulate the muscle to contract. As it
shortened to move the load, tension would be constant, if all outside variables
are eliminated. Such an occurrence looks like this.
A. The muscle builds enough tension to support and overcome the load.
B. It is able to shorten, as thick filaments slide thin filaments over them
C. No outside force obstructs this, therefore no new amount of tension needs to
be produced.
D. Iso = Same Tonus = Tension
Dynamic Contraction In Vivo, it is almost an impossibility to perform an
isotonic contraction. In order to understand this, you must consider a concept
known as
torque. Our body can be broken into distinct segments. The Upper arm, more
correctly referred to as the arm, articulates, or forms a joint with the lower
arm or forearm. When you flex( decrease the angle between two body parts ) at the elbow joint, you flex your forearm,
bringing it closer to your humerus( arm bone ). An axis is defined as a
straight line about which a body or a geometric figure rotates. Therefore, a
body part rotates around its joint axis. The force which is used to cause this
rotation is known as torque. As you know, the force required to move the bone,
changes through the specific range. I will further explain this relationship in
future articles. However, the point is this: In a barbell curl, as the weight
is curled, varying amounts of tension must be applied to maintain your ability
to move the load. Therefore tension does not remain constant, but is rather
dynamic, or in a continual state of flux.
Here is a brief summary:
A. Dynamic Tension, is also Referred to as Isotorque
B. In Life, you must rotate a body segment around an axis, thus calling for
varying levels of tension, unlike a controlled in vitro experiment.
C. Change in muscle length also effects this variable.
Positive Work Vs. Negative Work
In both of the above examples, a muscle can perform both positive and negative
work. Work, is of course defined as force X distance. The first domain we will
deal with is concentric contraction. During such an occurrence, force produced
by muscular tension overcomes a particular load, this is known as positive work.
Isotonically, the tension never varies once the load is overcome, however
Dynamically as we have seen this does change, though the load remains constant.
Therefore, concentric contractions, are your petal to the medal. Just as you
step on the gas to make yourself go faster, you use positive work to accelerate
your body, or a load.
A very important concept
to introduce is one known as negative work. Here, the external load, actually
assists the muscle in lengthening. The muscle still produces force, and the
load is still moved, but it is negative work. Keep the concept of assisted
lengthening in mind, because we will use it for a sure fire shocking technique
latter in this article! Such contractions are used by athletes to
decelerate,
much like breaking while in your vehicle. When we refer to these
throughout the article, we will do so dynamically.
Isokinetic Contractions
The term kinetic refers to motion. Isokinetic refers to an exercise which
maintains a constant, or same velocity throughout. This again, would be more
accurately used in vitro, and under more controlled conditions. In vivo,
velocity does change due to changes during rotation. However, the rate at which
joint displacement takes place can be regulated, even in Vivo. Thus, the term
isokinematic( remember kinemantics refers to space and time ) is more
appropriate. It is not what is used by most trainers however, therefore to stay
within this frame we will use the term isokinetic. And in doing so, we are
referring to a contraction, in which the rate of a concentric or eccentric
movement is constant. If you were to therefore lift a weight 5 inches, in 5
seconds, you would move an inch per second. Consistency is the key.
Isometric Vs. Static Contractions
Isometric As the name implies( metric ), this implies a
build up of tension, devoid of work.
Force X Distance( 0 ) = Work Done = 0 ( Load is not overcome )
Therefore, though tension is developed, no shortening in the muscle group
occurs.
Static The properties of your muscles, the connective tissue which binds them,
the tendons anchoring them, and the ligaments joining bones together are
elastic. Meaning, when you train, and you attempt to contract against a load
without moving, you are unsuccessful. That is-a small amount of shortening
actually does take place, but it is not appreciable, and also not rather
noticeable. Therefore, static is a more proper term used in Vivo. In Vitro a
muscle can be clamped and completely anchored so as to eliminate any
shortening.
Manipulation of The Above Concepts
Now for the pain aspect of this article. Our intension
is to apply the above concepts in order to maximize growth. Before moving
on, it is vital that you understand them.
Eccentric-Static-Concentric Coupling
It is a well
known fact, that higher levels of force can be produced during certain portions
of a repetition then others. This is based highly on the total amount of cross
bridges formed between myosin heads and actin binding sites.
Lowest To Highest Force Production
1. Concentric contractions produce the least amount of force. This is
due to the fact that only half of the available cross bridges cycle. Ccs
are also the most
energy costly of the three phases discussed.
2.
Static contractions can sustain greater poundages. In order to understand this,
you must realize the nature of such contractions. You see, tension actually
builds as you engage in such a movement. More and more myosin heads bind to
actin binding sites, until so many are bound that shortening is eliminated! As
you recall this is what creates the force produced by the muscle, and
consequently it is much higher then is its accelerating counterpart.
3. Eccentric Contractions can handle the highest
loads, and are the most energy efficient. The key to understanding this again
lies in cross bridge cycling. You see, though many of the cross bridges do not
actually cycle during eccentric training, they are pulled backwards. This means
that myosin heads cannot move forwards. In order to shorten, the myosin head,
like an oar you use to paddle a boat must come out of the water and cycle
forward first before a power stroke backward is used to propel your boat
forwards. During lengthening this does not occur, meaning that the
myosin does not come forward but rather remains bound to the actin. As the
eccentric phase continues, more and more myosin-actin cross bridges are
formed without subsequent forward movement, and therefore more tension is able
to be produced( force ).
Re-imagine yourself in that boat. What is
easier, to pull your oar out of the water to stroke, or to just leave it in the
water? Obviously the latter, and it is the same concept. Tension is able to
build to much greater levels and use no where near the energy required to
produce it.
Let The Pain Begin!
With this knowledge it is easier to see why eccentric exercise is more energy
efficient. Not only are fewer muscle fibers recruited, but less atp is used due
to the non cycling fibers( A good illustration is found when sprinting up a hill
as opposed to going down it ).
If one can
handle heavier loads within specific ranges of a lift, then it would be of great
benefit to use such knowledge to optimally overload the target muscle group.
I call the following method, optimal force or ETC coupling. Here is how you
execute it.
Version A
A. Choose your normal target weight for a particular exercise. Lets use
the Bench Press as an example
B. You will concentrically accelerate the weight upwards. ( 1-2 second
lift )
C. When you reach the top range of motion, your training partner will
increase the resistance by pushing down on the weight. You will resist for 1-3
seconds
D. This will be followed by an eccentric contraction, In which your
partner will further increase the resistance on the bar
E. You will begin again, with only the original weight as your
resistance. With partner's assisted resistance once again applied statically and
eccentrically.
Version B
The following is based on energy expenditure and force
production. It is meant to isolate separate aspects of the lift, so as to reap
optimal benefits from each.
A. You will utilize concentric super overload here. This means that you
only perform concentric contractions to absolute concentric failure. Your
partner will take the negative portion of the rep, and you will not focus on the static(
peak )
contraction.
B. This is followed
by 30-60 seconds of pure static contraction.
C. Upon completion have your partner spot you concentrically, while you
take the eccentric load( they lift the weight for you, while you lower it ). Continue until negative failure is reached!
The above
methods maximize workload, cross bridge formation, pain and of course muscular
growth.
Hyperplasia Prying Method Underground Shock Training At Its Best!
This ain't hypertrophy specific, its hyperplasia
specific! Throw your genetic preconceptions out of the window! First, I need
to state that this is a very hardcore training method. I must warn you, warming
up is an extreme necessity! You should be thoroughly stretched, and have broken
an excellent sweat.
I need you to once again examine a normal eccentric repetition. During such a phase
you voluntarily lower the weight under control. As discussed you are
performing negative work, and it is important to realize this: the load is
assisting the muscle to actually lengthen, i.e. filaments are being pulled
apart.
The prying method increases the assist aspect. It is a fact, that lengthening
exercises cause the highest homeostatic disruption in a muscle group. We take
it to a new level here. Instructions are as follows:
A. Choose an exercise. Here we use pull-ups an an example
B. When you reach the top of the movement you will not lower yourself
downwards. Instead you will be forced downwards! This means that your partner
will pull you down, as you fight to resist him. Normally, you would voluntarily
move with him, even if you did provide great resistance, it would still be to
some extent voluntary on your part. This is not the case within this method!
You must not allow him to pull you down. That is why this is called the prying
method. You are forcing the eccentric contraction here, not voluntarily
lowering the weight!
Again, this is an extreme
training method. And you will need to be warm, carbed up, and allow plenty of
recovery time, as much micro trauma will occur.
Additional Guidelines For Methods Use
Because this is an extreme
method, a tempo should be set. In other words, the training partner applying
pressure must control his prying technique. It should be a slow and painful
process lasting 4-10 seconds. If you can overpower your partner, do not rip
their arms off! You are prying, but it must be done with caution.
Ground Zero Method
Abcs own super moderator
Venom introduced this number to me. He calls it ground zero because of the
extreme stabilization disruption produced by it. I liken it to moving from a
machine to a free weight station in immediate transition. We will again use the
bench press as an example
A. You will choose an extremely light weight here. If you normally can
bench 250 10 times you will choose 135 here instead.
B.
Your partner will resist you on each concentric contraction only( meaning they
only add extra resistance on the up phase of the lift, which is the most taxing,
aspect energy wise in the exercise ).
C.
As you weaken, he or she will lower the tension
D.
When you can no longer take your partners resistance, they will release the
weight, and you will pump as many extra reps as you can. Here's what you will
find. The resistance provided by your partner provides a constant tension type of
feeling, as if you were performing bench presses on the smith machine. As soon
as they release the load, you will be in free weight mode again. Your
stabilizer muscles will kick into gear, and as they do so you will experience
what venom calls GROUND ZERO! It is at this
time when disarray causes your arms to shake
life leaves blowing in the wind! A concept which is almost unavoidable. As your nervous system
catches on, the shake ends, but the stimulus for growth continues well into the
next several 24 hour periods!
Relentless Tension Method
As discussed above, torque
is the varying tension produced to rotate a limb around a joint axis. The
amount of tension varies throughout the lift. There are two points that we will
examine within a lift:
1. The first is the bottom portion of the rep. During this phase, the
weight has been decelerated. Take the barbell curl, when the weight is lowered,
the biceps no longer have to support the load, and they are relieved momentarily
from their duty.
2. On the up phase, much of the tension is shifted on a number of
exercises. For example, on the barbell curl, we tend to shift the weight to the
anterior deltoids and lower back.
The relentless tension method takes care of these two aspects by eliminating
them. Thus, you will stop approximately 5-10 degrees before the weight is
completely lowered, and also fully lifted. Such a method is optimal for blood
pumps. Try performing 40 repetitions on the leg press or extension machine with no release in
tension. It will be a workout you wont soon forget, guaranteed.
The second way to
manipulate such a method is to eliminate just one aspect of the movement. Take
the dumbbell fly for example. The whole point of the exercise is to emphasize
the stretch, and to not only stretch the fascia, but also add sarcomeres in
series. The same can be applied to sissy squats and preacher curls.
Emphasizing the stretch has been shown in countless studies to boost hypertrophy
to unfathomable heights!
Isokinematic Contractions Utilized
Isokinematic contractions
factor in the rate at which a repetition is performed. In the strictest sense,
the entire rep, from eccentric to concentric should remain constant from start
to finish. The following is also referred to as the isotempo method. It is
important to realize that training adaptations are based on homeostatic
disruption. As Old School has discussed, change is a vital tool in achieving
this desired effect. When I say change, I am not simply referring to repetition
range, and exercise selection, but also to tempo. Indeed, the rate at which you
lift a weight will most definitely effect the outcome. Isotempo training is
simply a tool of the trade. A shocking method if you will, and one which will
give you that much needed edge.
Basic Isotempo Guidelines
1. For nervous system Adaptation and Fast Twitch IIB fiber stimulation,
you will choose a weight that does not exceed 20 seconds. This is mainly a tool
for strength gains.
2. For Hypertrophy of both fast IIB and IIA fibers the set should last
from 30-70 seconds
3. Above This will build mitochondrial density in IIB and IIA and target
slow twitch Fibers.
4. Choose weight that will cause you to fail in the desired time range.
If this is a barbell curl, and it lasts 32 seconds, you will then divide the
time into equal segments. Meaning the eccentric portion will mirror the
concentric portion. Your partner will count for you. Thus, if you decide to
choose a two second tempo, then you will lower the weight in two seconds, and
raise it in two seconds. This is a continual motion and the eccentric should
blend smoothly as it transitions to a concentric repetition. The above tempo
would give you 8 repetitions in 32 seconds.
5. For maximum homeostatic shock, choose
a tempo which challenges your preconceived habits. Take the squat as an
illustration.
You may be used to slower movements. By choosing a faster rate, you will build
greater explosive properties in the muscle, enhance coordination, and build your
lung capacity. Conversely, if you are used to a more explosive tempo,
slowing the pace( while staying within the desired time frame ) will build
stabilizer muscles in the back, abdominals, and adductors that are not used to being
called into play. In fact, a faster pace relies more heavily on momentum, so a
decelerated rate can yield tremendous hypertrophic benefits.
Isokinematic Strips
There are
many trainers who judge sets based purely on tempo. This means that when an
athlete can no longer handle a weight, at a specific time, that the set is
complete. Such strategies assist trainees in many ways. For one, during the
squat, form is of the essence. If the goal is completeness and to improve form,
then it is beneficial to perform the set under complete control. Secondly
it provides a more quantitive assesment for athletic progress( see
biomechanics an introduction
). Thirdly,
this can be used for extreme poundages. If one is to use extreme weight, then
it is important to control that weight. Lets apply the following
steps
1. The following example is meant to monitor the quality within a strip
set. We will use the heavy squat to illustrate our point. Lets say, that you can squat
400 pounds 3 times at approximately 3 seconds per eccentric and concentric
phase. This totals 18 seconds.
2. As soon as you no longer can maintain this controlled rate of
ascension and decention, then you will immediately strip the poundage by 10 percent,
meaning you will now be lifting 360 pounds. The tempo will again be three
seconds down and three seconds up. When control cannot be maintained for the
allotted time, you will again strip 40 pounds off of the weight and continue.
3. Enter as deep into the pain zone as is possible.
Such controlled lifting speeds will facilitate one of the greatest shocks of
your life! You see, most people perform strips sets, and the quality of their
repetitions falters horribly, this corrects such habits. Consequently this same
ideal can be applied with varying tempos. I.E. a longer negative then
positive tempo.
Adaptive IsoKinematic
Tension
When I say
adaptive, I am referring to a two partner system, based purely on control. Here is how
it is accomplished
1. Begin by choosing an exercise. We will use the barbell curl. Place a
light weight on the bar, or no weight at all. This can be used with a broom
stick if on a trip. A towel can also be instituted if triceps are being worked, or
if hammer curls are being mimicked.
2. Choose a sufficient tempo you would like to maintain. As you lift
the weight, your partner will maintain a steady amount of tension on the bar.
It should be notably heavy( depending on the desired effect ).
3.
When you can no longer maintain tempo, your partner adapts by lessening
their manual resistance on the bar. Thus, you continue in a smooth fashion,
until the bar itself becomes impossible to lift!
Torturous Varying Tension Method
I saved this
for last, because it is truly one of my all time favorite shocking methods.
Most will never have what it takes to gut this one out.
Steps
1. As with the adaptive tension method, this can be performed with a
broom stick, or a light weight. Take the barbell curl. If you normally can
curl 135 10 times, you will perform this with 65 to 95 pounds( or with pure
partner assisted tension ).
2. Similar to 21s the focal point will vary throughout the duration of
the set
3. The person lifting the weight will lift like normal through a full
range of motion.
4. The partner is who determines the pace of the set! It is their job
to do as follows: To stay true to form, we will use a 21 rep scheme. On the
bottom half of the rep both concentrically and eccentrically the training
partner will apply an extra amount of tension. However for the second half of
the repetition they will not apply any tension. This is to continue for seven
repetitions
5. Now, your partner will stop applying tension to the bottom half of the
rep, and begin applying it to the top half of the repetition for 7 total reps.
6. Rep out the weight to failure!
There are variations to this theme. For example, there may be an aspect of your
lift you want specifically strengthened. With this in mind, your training
partner will only apply excess pressure during that specific portion of the
repetition.
