The need for speed Part 2
Posted January 29th, 2008 om www.myfittribe.com
Last we focused on the upper body and its effects on running
technique and speed. Now it is time for the lower body to be
dissected. Let us start with the hip, (the forces of power
production are about seven times that of the ankle when sprinting)!
In the hip area there are lots of muscles that in different ways
affect running and speed production. Most important are the glutes
and the hip flexors. The glutes are one of the largest and most
power producing muscles in the body and combined with the hamstrings
extend the hip and helps you move forward. Unfortunately, it is
often deactivated and cannot fully deliver at its peak. This is
mostly due to stiff and shortened hip flexors, a problem that is
very common from too much sitting down or sports where you act
leaning forward, eg. in hockey, golf etc. Stiff and shortened hip
flexors will also lead to decreased stride length and disturbs the
rotation of the spine, it will force you to rotate more to be able
to keep your stride length and sprint at full speed. This unnatural
rotation costs the system an unnecessary energy loss and keeps you
from optimal performance in more ways than one. It is very important
to have good flexibility in the lower core, the hips and legs. In
order to be able to keep your foot longer on the ground during the
stride you need to be able to fully extend in your hip, knee and
ankle joints.
The hamstrings work in close connection with the glutes in the hip
extension phase in running and therefore also become affected by any
problems with the hip flexors. So you can see the importance of
giving proper attention to it. Else you have no chance of performing
at top level. But if you put proper attention to the stretching and
lengthening the hip flexors, you should see to it that you strive to
train the glute hamstring complex to work as one. This to ensure
that you don’t get any strength imbalances between them. I often see
this problem in athletes though. Often they have pretty strong
glutes but lack sufficient hamstring strength and development. This
leads to higher injury risk and faulty running technique. So it is
very important to make sure your hip flexors are thoroughly
stretched for optimal potential for speed and power in the hip area.
Balance between quadriceps and hamstring strength is also a big
concern when you aim for speed. Most people will find that they feel
more in their quads than in their hams when sprinting. This is very
common and a indicator that you need to strengthen your hamstrings.
If properly trained you should feel more in your hams than in your
quads! If not then you know what to do.
Another common problem is insufficient flexibility in the quads. The
flexibility of the quadriceps determines the ability to bring the
ankle of the recovering leg past the knee of the driving leg at a
height where the resting leg ankle is actually above the driving leg
knee. This ability is not solely due to flexibility but also on core
strength and calf strength.
The ankle is the last link to the feet and the ground so it is
important that there is also good flexibility and strength around
this joint. When sprinting at max speed you fully extend the ankle
joint and therefore it is of importance that there are no
limitations, in either muscles or structure. A lot of people would
be helped if they received some soft tissue treatment around this
joint and maybe even some chiropractic treatment of the joint. It is
a very abused and neglected joint, considering its great importance
in as well sprinting as everyday work.
Next time I will start to focus on how to train for speed. I will
cover flexibility, strength, drills and running. So stay tuned!
The need for Speed! Part 1
Posted December 30th, 2007 om myfittribe.com
Everybody who has ever been involved in some sort of sport knows the
need of speed! In almost every sport it is a necessity in order to
become successful. Even our ancestors were in need of speed, or they
got eaten- or beaten to death by the enemy. So it´s in our blood.
But even though it is such a necessity in sports I often see people
who don’t have it developed to their full potential. They may train
their strength (often focused around their legs), their agility, run
their sprints and so on. But in order to become the fastest you can
be you have to incorporate a lot of things and know a bit about how
the body works and the mechanics of sprinting. In this article
series I am about to share with you the things I consider to be of
importance and try to make this complex and widespread area a bit
more accessible to you. And just for the sake of confusing you (just
messing around) I will go from upper body to lower body in this
article series and finish up with a bit of training methodology for
speed.
First and foremost I would like you to understand that the body
works as a whole, and in sprint you need it to work in the forward
direction and in a relaxed manner. Anything that deviates from this
will to a certain level decrease your quest for optimum speed. I
often see this in the upper body, both unnecessary rotational
movements and tensing up. To clear things up a bit let us examine
the upper body´s effect on sprinting.
Start with the shoulders, they should be able to move or “roll”
fluently forward and backward with each stride, working into the
opposite direction of the hips and legs. So if you don´t relax your
shoulders but pull them up towards your neck, you will DIRECTLY
affect your hips and sprinting abilities. This means you need to
keep your shoulder girdle loose and relaxed to be able to generate
maximum speed, this goes in all sports. It also goes for the “see
saw” movement- technique I often see in many athletes while
sprinting. Another problem that starts in the shoulder girdle is the
see-saw movement across the body. This will transfer the force that
is generated into an exaggerated rotational movement of the upper
body, which will have several negative inputs on their running.
First of all the core will have to try to stabilize and lessen the
rotational force deriving from this movement, keeping it from
translating through the body. This energy loss will also affect the
core in its ability to stabilize and keep optimal alignment
throughout the spine and the hips, for optimal sprint posture and
mechanics. The core acts as a transition between the upper and lower
body while sprinting and should also be trained accordingly – see
earlier article.
So what then causes this faulty, energy wasting technique? As you
may have observed a lot of athletes are “naturally” forward and
inward rotated in their shoulders. This faulty alignment will of
course also affect their arm movements, hereby making the see-sawing
movement “natural” for them. Not good in any way! So if you
recognize yourself then the first step here is to plan a corrective
phase for your shoulders in order to (re)establish a natural pattern
that is more in line what the body was designed for. I would start
off with stretching the short muscles around the shoulder joint and
then strengthen the muscles that are elongated and weakened. I would
assume that some of the muscle on your short list would be chest,
lats, front deltoids and biceps, while the rotor cuff, the middle
and lower trapezius and the rhomboideus are weak and elongated. So
if you start with checking them you should be on your way. I will
address the training for speed part later on in this series, so stay
tuned.
On to the arms then! The arms are important in developing speed.
They actually precede the leg action when sprinting. So you need a
strong upper body to be fast, just look at today top sprinters – not
exactly what you would call sissies, are they!? This does not mean
however that you should curl ´til you die; the muscles you need to
train are the muscles around your shoulder joint. Which brings me to
this week’s lesson- Which muscles attach and work around the
shoulder joint?
Until next part train smart,
Stretching - The Basics Part 2
If you have read the previous part of this series you should have a basic understanding of the science behind stretching. In this installment I will focus on the more technical parts of it, and go into how to perform the different stretches in order to get the most out of them. The stretches I cover are primarily the static ones, since I see them being misused daily I would like to steer things up a bit. This part will be more directly accessible, I promise – more practical, less technical!
As you perform a stretch you should always strive for perfect posture- chest up, chin in, shoulders back and down, tighten abs and so on. You should also, in most of these stretches, try to look straight ahead and keep your body in a neutral position, no rotation if possible. Through these stretches we want the body to get back to its normal and “correct” posture and alignment, therefore no deviations allowed!
We will look at two different stretches for most body parts, one less beneficial that is commonly used and one that I recommend. If you are already using the latter one then great, but maybe there is still something you missed out on the performance, which I might be able to help you out with through this article!? I will focus mainly on the larger muscle groups, but if you find afterwards there are some muscles that didn´t receive the attention they deserved or if you have any questions about other stretches – please post a comment or email me.
Let´s start from the bottom up, shall we!?
Calves
When stretching your
calves there is basically one thing you
should strive for, which is to get as sharp
an angle possible between the foot and the
shin. I would also prefer you to place the
pressure on the ball of the foot and not
your toes; this to assure that you stretch
your calves and not your toe flexors! You
should also take into account that the calf
consists of two different muscles, the
gastrocnemius and the soleus, where the
first one passes the ankle as well as the
knee joint. This you must take into
consideration - when stretching the gastroc
you should always have a straight leg!
So when stretching the calves I suggest that
you begin with straight legs and then bend
the knee slightly in order to focus more on
the muscle located underneath, the soleus.
One of the most common stretches is the one shown in fig 1, where you stand with your hands against a wall looking like you are about to push the wall away. This stretch is fine but you will have a hard time relaxing your calf enough to give it a real thorough stretch. I prefer the one where you place your foot against the wall (fig 2) and gently strive with your hips towards the wall, thereby sharpening the angle between foot and shin. This makes it easier to relax the muscles and you can calibrate the force of the stretch more easily.
Hamstrings
When stretching your hamstrings you shall always see to it that your foot is straight and not rotated in either direction, this to ensure that you will stretch each portion of the hamstring equally. Keeping your leg straight is not as important, it works with a slightly bent knee as well. But the most crucial thing to ensure when stretching hams is that the movement takes place around the hip joint and NOT your lower back, I cannot stress this enough!!! Your hamstrings originate from your ischial tuberosities and not your lumbal spine, like some seem to believe. So when you perform your stretch always keep your lower back straight- try to think of yourself as a Swiss knife, opening and closing around the hip joint.
One of the most common stretches for the hammies is the one where you place your foot on a bench and bend over (fig 1). I would not recommend this. First of all people have a tendency to bend their lower backs more than their hips here, as mentioned above, and secondly they often end up rotating their foot outwards, opening up the hip. This will place more stretch on one part of the hamstring than the others. So I would suggest instead you sit on a bench, fig2, with one leg on the bench and the other one off, resting on the floor in a “hurdle” position, this will stabilize you hip joint and give you a much better and safer position to start out from. From this position let you body travel forward with your chest held high. And at any cost try to avoid bending your lower back!
Gluteus
The glutes are made up of several muscles, but for this article I will focus on the buttock as a whole. The most common stretch ought to be the one where you sit on the floor hugging your knee while trying to get it to your chest, fig 1. The stretch itself is not a bad one. But if you are tight and stiff in these muscles, you might not get the force you need with this one. So I use a derivation of it where you place your leg on the floor in front of you, fig2, and let your body weight do the job for you. I carefully lean towards the leg.
Quadriceps
You have almost certainly
stretched you quads by standing erect and
trying to pull your heel towards your rear
end, fig1!? This must, pardon me, be one of
the most useless stretches you can do for
your quads. Why? Well, first of all, you
will separate your knee joint when doing
this letting all the force push your knee
cap into the joint. Secondly, if you do not
have the abs of Jamo you will probably
increase your lordosis, which will remove
the stretch effect from the quad itself and
instead put your lower back under that much
more stress. And this is only some of the
side effects I could mention about this
variation. But let´s leave it at that.
What I do recommend is the version shown in
fig 2. Here you reduce the stress on your
lower back, ensuring you get the desired
stretch in your quads by stabilizing your
hip and focusing the pressure above the
knee, to relieve the knee joint. For the
best effect when performing this variation,
try to lower your hip towards the bench
while you pull your heel towards you
buttock.
Lats
When stretching the lats the one thing that most people miss out on is the fact that the lats attaches to the hipbone, which means that in order to get a full stretch you need to bend over a bit for a slight flexion in the hip. This is a part you lose when you do the basic standing side-bending stretch, fig 1. So I prefer to use the one in fig 2 where you bend over your flexed hip as a large C and use your free hand to push away and to create a greater stretch in the lats.
Chest
An important consideration when trying to get the most out of a chest stretch is to focus it around the shoulder joint- leave that poor elbow out of it! Far too many just throw their hand up on the wall, fig1, with an overstretched elbow, or the opposite- bend the elbow but leave it hanging in the air, so to speak, while pushing their hand towards the wall, turning their upper body into the same direction. What this does is it removes the focus and stretch effect from the chest, in the first example putting more stress on the elbow, in the second one not stretching at all!
A better way is to put the entire lower arm up against the wall, fig2, preferably over shoulder height, supporting the elbow. Stand with your upper body facing straight ahead, chest up, straight back, then take a step forward with the same side leg, hereby preventing the upper body from rotating towards the wall.
The pectoral is a broad fan shaped muscle with its different parts attaching both to the clavicle, the sternum and the ribs (usually referred to as the upper, middle and lower part when benching). So think about this, if you train the chest in different angles, why not show it the same amount of respect when stretching afterwards?! You need to do this in different angles by the same reason you have to vary the training angle using an incline, straight and decline bench - to cover all the fibers. The most important part to stretch is the descending one, which have the greatest tendency to shorten and pull the shoulders forward. The higher up you place your arm the lower fibers you affect.
Front Shoulders/Biceps
A tight bicep and front shoulder combined with tight chest muscles is one of the reasons for internally rotated shoulders, which in time may give you tons of problems more serious than just a visually incriminating lousy posture. So please do not neglect these muscle groups, and make sure you perform the stretch correctly, in my opinion best done according to fig.2. Important notice: Make sure you grab the bar or support your hand with the palm facing up as you internally rotate your arm! The one in fig.1 is commonly seen in the gym, but it does not give you a sufficient stretch of the biceps, due to lack of rotation of the arm. It is also more beneficial to stretch one arm at a time as you pretty much always have a imbalance of flexibility between the sides, which will not be addressed when stretched together.
Triceps
When stretching your triceps always see to it that your elbow points towards the ceiling, or the sky if outside ;-) and make sure you at the same time get your hand as close to your shoulder as possible. I often see the first part being done right (fig 1) but often the second part is not done correct, they just flex the biceps a bit to get a stretch in the triceps. But to give it a thorough stretch you need to use more force than that. Use a rope or something like it to pull your lower arm down towards your shoulder and back. At the same time use a wall to lean into, so you can get a real stretch in your triceps as seen in fig.2.
Neck
The most common neck stretch is the one where you grasp your head by the ear and tilt it to the opposite side. This version puts unnecessary strain on your cervical spine due to exaggerated lateral flexion. To avoid this simply sit down on a bench and grasp the seat with the hand on the side being stretched and slightly lean away. This to lower your shoulder girdle to initiate the stretch, so you don´t have to bend your neck as much to the side for a good stretch. It will also put less strain on your spine and save it for the future.
So now you only have to put this in use and keep stretching as a regular part of your work out. Please reread the first part to know what and when to use the different kinds of stretches.
Machines and Sport Specific Training
Posted November 7th, 2007 om myfittribe.com
In a perfect world you would now be able to
read an article about speed training or get
the second installment of the stretching
basics, but once again the world proved to
be far from perfect as my regular computer
crashed and I lost most of these two
articles. I am a trainer, not a computer
freak, so please forgive me for not making
backups more than once a week… So sadly
enough I am out of a pc for now, but just so
you would not have to suffer the loss of
something new to read on sport specific
training until my new one arrives, I bribed
one of my friends to lend me his computer
for an hour or two. Here´s what I was able
to put down for you in that time, I hope you
will enjoy it and that it will be of use to
you.
As a trainer and coach spending countless
hours in different gyms, you often see stuff
that makes you go - hum I wonder… Which is
just what happened this last week, while
sneaking in one own quick training session
between clients.
I was about halfway done when a guy in his
late teens came in to start his session. I
knew he was from a school with a special
sports program for talented individuals, I
reckoned he was into either soccer or
hockey. You can almost always sort them out
by their training clothes… He started out
with bench press on the Smith machine,
without any previous warm-up, progressed to
the machine leg press and, after that, the
lat pull down machine. By now I was pretty
curious whether he himself had designed the
program, or if it had been given to him by
the school coach. And ok, I was even
thinking a couple of things I cannot print
here…
Anyways, I walked up to him and checked if
it was ok to ask him a question on who had
helped him with his program and what his
goal was? The response in order was: “The
Coach” and “to get stronger for sports”… To
clear things out I needed to know whether he
had been specified to do the program as such
or if he himself had been modifying it,
changing the prescribed exercises. But no,
he had actually been following the given
program in its entity; he even showed me the
print-out! On this I had to ask whether the
coach had not told him that he would be
better off substituting these exercises with
real bench press, squats and chins or at
least “real” lat pulldowns. The answer made
me speechless (which is a rare happening)!
He said his coach had told him that there
was no real difference between these
exercises and the ones he did, besides from
being able to use more weights on the
machines and still maintain focus on the
muscle he trained! I felt the urge to give
the kid a lecture and set him straight on
some details, but being too short in time I
had to restrain myself and just made a small
mental note to call his coach and ask for
his credentials…
Instead I will now have to give you dear
readers the short version of the lecture on
the use of machines in sport specific
training. Which is – It sucks, big time!
When using a machine, you take away all core
integration, all stabilizers and
coordination between different synergists (muscles
working as a unit), in short terms. This
will make you more prone to injuries,
overall weaker and less productive on the
field. In my book that is not the way to
train for optimum performance!
Picking exercises to increase your
performance, you should use mainly those
that put both your body and nervous system
on toes, so to speak. Please don´t make the
common mistake to confuse sport specific
training with bodybuilding! Using a
traditional bodybuilding program will often
result in a big portion of non-functional
mass, which can actually make you perform
worse on the field! This is not to say that
using bodybuilding protocols and combining
them with “sport specific application able
exercises” is useless- if done right you can
get functional mass out of that, too. But
back to the selection of exercises! As I
wrote earlier they should keep both your
body and nervous system on its toes, and to
make it easier for you to choose the right
kind of exercises next time, I will give you
a foundation to stand on.
When choosing exercises to use as a base,
you should look at two aspects. First- is
this a natural movement for the body or a
derivation of it? If yes to the first it
will probably be an exercise that is ok to
use. We have some original or “primal
pattern” movements as one coach would say.
They are to squat, to lunge, to press, to
pull, to rotate and to bend. Always identify
the most commonly used patterns in your
sports and evaluate how well you perform
them, and look for restrictions that might
hinder your progress in them so you then can
correct these restrictions and further your
progress! I would then suggest that you
include some variation of each pattern in
your workout, in my experience there is
always sometime you will need to perform one
of these patterns in your sport and daily
life. You should also pay some attention to
get an even ratio of horizontal and vertical
work when working with press and pull
movements! People often have a tendency to
do more horizontal pressing, bench
variations, and vertical pulling, chins
variations, in relation to their opposites.
This will lead to unnecessary strength
imbalances around the shoulder joints and
actually make you weaker in both of these
movements. So keep an even ratio. Now you
have a bit of insight in which kind of
exercises to choose on to the second
selection criteria.
You should always strive for as much motor
unit activation as possible. This is after
all how the body responds to demands on the
field - the more efficiently you can use
your muscles the better you will do
obviously!
So how do I know the level of neuromuscular
activation? You can use what the old German
strength physiologists call the Scale of
Motor Unit Recruitment. There are seven
levels of muscular activation and you should
strive for at least level five or higher.
Compound vs. Isolation Exercises
(Neuromuscular Activity — NMA)
Level 1
Isolation exercise on variable resistance
machine, like leg extension on cam type
machine like Cybex and Nautilus machines
Level 2
Complex exercise on variable resistance
machine, like leg press on Nautilus machine
and their likes
Level 3
Isolation exercise with constant resistance
machine, like Preacher curls with pulley and
Pushdowns on a cable machine
Level 4
Complex exercise with constant resistance
machine, like leg press on standard machines
Level 5
Isolation exercise with free weights, like
incline curls and side laterals
Level 6
Complex exercise with free weights, like
cleans, squats and other basic exercises.
Level 7
Complex exercise with free weights and an
added uncertain factor, like dips on rings,
rope climbing and such
Just to clear it out, for those who do not
know, an isolation exercise is done over one
joint and a complex over multiple joints.
Now you should have some basic knowledge on
how to pick your exercises and know why you
will never get the same results by using
machines as with free weights or your own
body! So put your knowledge to use and start
training for performance now.
Had the Coach who constructed the kid´s
program earlier known these basics, then his
apprentice would probably have improved his
chances for reaching his goal to perform
better - and be functionally stronger!
Stretching - The Basics! Part 1
Posted October 25th, 2007 om myfittribe.com
There is and will always be different
opinions about the importance of stretching,
and the benefits of it! But anyone who has
spent some time in the fitness and sports
industry knows its value. In this two part
article series I will cover the stretching
basics. In this first one will focus on the
“technical” pieces while the second will be
more about the “practical“ parts.
Most people tend to see ordinary stretching
and flexibility training as one and the
same, and far too many do not pay enough
attention to this part of their training
either, which is a BIG mistake! Almost
everyone starting out, it may be the
beginner just getting into strength training
or the seasoned veteran starting over again
after some time away, should pay ample
amount of time with it in order to be able
to perform their strength training exercises
in proper form. Many simply do not have the
flexibility and/or correct relationships of
muscle length to do the lifting exercises as
they should be done. I get to see this time
after time. It is NOT the range of motion in
one SINGLE muscle that is of interest here,
it is the RELATIONSHIP BETWEEN muscles
around a joint that is important. Each and
every muscle in a joint NEED to be at
“normal” length, so you can perform the
movement around the joint as it was designed
and not to put stress on the wrong
structures! So the first thing to do and
concentrate on is length balancing between
the muscles around the joints! It does not
matter if you increase the range of movement
in your pectorals, chest muscle, if other
muscles around the shoulder joint are off
the chart, so to speak. Yes you may get a
greater range of movement in your chest
press exercise, but that may also stress
your shoulder joint in a bad way and result
in injury to it or its surrounding muscles!
So I thought I should sort things out a bit,
give you an introduction and my two cents on
how to integrate stretching in your daily
training. I will focus on the most common
types of stretching and try to explain the
“best” use of them. But first let us have a
look at some of the benefits you might enjoy
by adding a serious and effective
flexibility part to your training. I guess
fellow tribe member Julien has done his fair
share… And let us at the same time look at
what exactly happens when you stretch a
muscle.
Some benefits in no particular order:
1. Increased range of motion
2. Decreased recovery time
3. Lower risk of injury
4. Improved performance
5. Better posture
6. Less neck and lower back pain and
problems
7. Better joint health
8. Less energy cost to the body
What happens?
The stretching of a muscle fiber begins with
the sarcomere, the basic unit of contraction
in the muscle fiber. When a sarcomere
contracts the area of overlap between the
thick and thin myofilaments increases. As it
stretches, this area of overlap decreases,
allowing the muscle fiber to elongate. Once
the muscle fiber is at its maximum resting
length, this is when all the sarcomeres are
fully stretched, additional stretching puts
force on the surrounding connective tissue.
As the tension increases, the collagen
fibers in the connective tissue align
themselves along the same line of force as
the tension. So when you stretch, the muscle
fiber is pulled out to its full length
sarcomere by sarcomere, and then the
connective tissue takes up the remaining
slack. When this occurs, any disorganized
fibers are realigned in the direction of the
tension. This realignment is what helps to
rehabilitate scarred tissue back to health.
When a muscle is being stretched, some of
its fibers lengthen, but other fibers may
remain at rest. The current length of the
entire muscle depends upon the number of
stretched fibers. The more fibers that are
stretched, the greater the length of the
stretched muscle will be.
The nerve endings that send all the
information about the musculoskeletal system
to the brain are called proprioceptors.
Proprioceptors inform the brain about the
body position and its movements. They detect
any changes in physical position, movement
or displacement and any alteration in
tension, or force, within the body. They are
found in all nerve endings in joints,
muscles and tendons, the proprioceptors
related to stretching are located in the
tendons and in the muscle fibers. So when
you stretch your muscles, the body must
adapt to this new position of location.
There are two kinds of muscle fibers- the
intrafusal and the extrafusal muscle fibers.
Extrafusal fibers contain myofibrils and are
the ones we usually refer to when talking
about muscle fibers. The intrafusal fibers,
also called muscle spindles, lie parallel to
the extrafusal fibers. These are the primary
proprioceptors in the muscle. Another
proprioceptor involved during stretching is
located in the tendon near the end of the
muscle fiber and is called the Golgi tendon
organ. There is also a third type of
proprioceptor, called the Pacinian corpuscle,
it is located close to the Golgi tendon
organ and is responsible for detecting
changes in movement and pressure within the
body. As stated earlier each of these three
will be subjected to some kind of
“disturbance” during stretching - as the
extrafusal fibers of a muscle lengthen so do
the intrafusal fibers.
The muscle spindle contains two different
types of fibers, or stretch receptors, which
are sensitive to changes in muscle length
and the rate of the change. During a muscle
contraction a tension change occurs in the
tendon where the Golgi tendon organ is
located. The Golgi tendon organ is sensitive
to such changes and the rate of them, so
these factors will affect your stretches in
different ways. Read on…
The Stretch Reflex
When a muscle is stretched the muscle
spindle records the change in length, and
the rate of such, and sends signals to the
spinal cord, which conveys this information.
This triggers the stretch reflex, attempting
to resist the change in muscle length by
making the stretched muscle contract. The
more sudden the change in muscle length, the
stronger the reactive muscle contractions
will be- plyometric, or "jump" training is
based on this fact. This basic function of
the muscle spindle is to help maintain the
muscle tone and protect the body from injury.
But this can also be an obstacle during
stretching if done wrong. Therefore it is
very important not to force your self or to
do any hasty movements while stretching. One
of the reasons for holding the stretch for a
prolonged period of time is that as you hold
the muscle in a stretched position the
muscle spindle becomes accustomed to the new
length and reduces its signaling. Gradually,
you can train your stretch receptors to
allow greater lengthening of the muscles.
So now back to the different kinds of
stretching:
1. Ordinary Static Stretching - The most
common type of stretching is where you hold
a muscle stretched in a fixed position for
about 30-60 seconds and thereafter slowly
ease out of it. This is a great variation to
use after workout or during the day to get
your muscles elongated, or to keep them in
their current state. I would suggest you do
each stretch 2-3 times for best results.
2. PNF (proprioceptive neuromuscular
facilitation) is often a combination of
passive stretching and isometrics
contractions. The use of contractions will
trick the body into letting you go into a
deeper stretch (see the different mechanisms
above) and this is a very useful method for
developing flexibility in a smaller time
frame. As a trainer and therapist this is
the way I stretch my clients most of the
time. There are a lot of different PNF
methods out there; here are some frequently
used.
1. Hold-Relax are the most common method.
You fire the tight muscle either against a
fixed object or your partners hand for about
10-20 seconds. Then you relax and lightly
stretch out the muscle to a new position and
hold it there, repeating the procedure
another 2-3 times.
2. Antagonist Contraction you passively
lengthen the tight muscle to it end-range.
Then you concentrically contract the muscle
opposite to the tight muscle, the antagonist
that is, to reach a new end range. This
technique incorporates reciprocal inhibition
- when one muscle contracts its antagonist
relaxes.
3. Hold-Relax with Antagonist Contraction is
in my opinion the best and fastest way to
increase the range of movement in a single
muscle by using a combination of the two
methods described above. When you relax your
tight muscle you will at the same time
contract its antagonist.
These static stretches with prolonged
holding positions are usually done in
warm-ups, which isn´t all wrong - please
read my warm - up article about this subject!
But here the length monitoring cells in the
muscle are stretched without the brain being
able to monitor the actual change in length.
So what happens in this case is that when
you move out of this new position the
information to the brain does not match the
information already stored there for the
“standard” movement, whereby the brain tries
to figure out how to modulate the new
movement to match the stored information.
This can affect you in such a way that when
you do an exercise your mind automatically
miscalculates the information sent to it, as
your regular and safe standard no longer
matches your brains standard, which elevates
the potential risk of getting injured from
that exercise. This is more pronounced when
doing fast ballistic movements. But of
course there are exceptions to this rule,
too, of not doing static stretching during
warm up, which I will come back to this
later on in the article.
I would suggest you use this kind of
stretching primarily in rehab, after
workouts or in separate sessions for
increased flexibility and joint health and
integrity.
Stretching directly after a work out may
enhance recovery due to increased
circulation etc., but I would not use it as
the primary way to increase length in a
muscle. After a work out the nervous system
is at work for some time and it will negate
the stretching effect. So if your goal is
muscle length and flexibility then you do
best separating it from any nervous system
teasing training!
Words of caution though, never force your
self into a stretch or perform it too
quickly. A stretch should never hurt, it can
be more or less painful but it should not
hurt!!
3. Dynamic Stretching was also mentioned in
my warm-up article, but here´s a quick recap.
This method of stretching is based on larger
movements done in increasing range of
motion. You should do it in slow continuous
movements. When you keep moving your brain
constantly monitors the change in length of
the muscle and makes the necessary
adjustments accordingly
This kind of stretch is the one that I would
suggest for warm-ups, but as I wrote earlier
there are exceptions to the rule. I touched
a bit on this in the warm-up article, but
left out some information that I will share
with you now.
But first let’s recap:
You use static stretches mainly to elongate
specific muscles and use them in preventive,
rehabilitating and restoration purposes.
Dynamic stretches are primarily used as part
of the warm-up to increase range of motion
in a brain-friendly way, so to speak.
On to the exception now!
There are three types of muscles and they do
not all respond to stretching the same way.
A muscle in the body is comprised of both
fast twitch and slow twitch muscle fibers.
Fast twitch are best suited for power and
speed, whereas slow twitch are used more in
prolonged work situations. Your postural
muscles are predominantly slow twitch, also
referred to as tonic muscles. Your fast
twitch dominant muscles are also referred to
as phasic muscles. The third type is
composed of fairly equal parts slow and fast
fibers, so these muscles don’t fall into
either the tonic or phasic group.
The interesting part is that the tonic
muscles react to faulty loading situations
in a very different way than do phasic
muscles. When overworked to elicit a
response your tonic muscles will elongate
and weaken, while the phasic muscles shorten
and tighten. But that is not all! The tonic
muscles will also become more and more
excited and try to do the work for the
related phasic muscles. This is very
important information, because a short tonic
muscle will rob nerve energy from other
important muscles and alter your
biomechanics! So you could, and sometimes
should, implement stretching of the tonic
muscles in your warm-up, but best done in
conjunction with dynamic to get the brain
and body to work as a whole.
Here is an overview of common tonic muscles
for you to see which muscles might be in
need of stretching before a work out:
Muscle with tendencies to be short/tonic
Upper Trapezius
Levator Scapulae
Short Cervical Extensors
Pectoralis Major
Pectoralis Minor
Erector Spinae
Psoas
Rectus Femoris
Piriformis
Short and long Adductors
Gastrocnemius
I hope you got a bit of insight on
stretching through this article, on what
happens, what to choose and when, since
stretching may be one of the more important
tools, if not The most important tool - to
help balance and align the body and its
biomechanics.
So let’s now make time for some serious and
well-planned stretching. In the next
installment of this article series I will
let you in on how to do the, in my opinion,
best stretches, for you to reap the benefits
you would like and could expect of
stretching - not just going through the
movements “for the good cause”, or worse,
stretch the wrong muscles!
To be continued…
Hypertrophy basics and chest training
template
Posted September 27th, 2007 on
myfittribe.com
My first few articles for myfittribe have
focused on overall performance. So some of
you might have got the impression that I
only train athletes, which is not the case.
To change that, I am going to give you folks
an article about chest training. It´s not
for the beginner but even as such you might
get some ideas to try out.
First though, I want to give you some
insight on why I choose to design the
program the way I do. There are two kinds of
hypertrophy, sarcoplasmatic and myofibrillic.
Sarcoplasmatic hypertrophy is an increase of
the non-contractile parts of the muscle
fiber, the sarcoplasm. It stands for about
25-30% of the muscle volume. But even if the
muscle volume itself increases the muscle
fiber density per unit will decrease, and
the strength enhancement will be negligible.
This kind of hypertrophy is a result of
conventional bodybuilding training in the
10-15 reps range. Myofibril hypertrophy on
the other hand is an increase in myofibrils,
the building blocks of the muscle
cell/fiber, which in turn are able to
contract and build up tension in the muscle.
This kind of hypertrophy increases the
density/volume of the myofibrils and
therefore increases the potential for
muscular strength. This is best done using
heavy weights and low reps in the 1-5 rep
range.
Low rep training with heavy weights also
gives your nervous system an ample workout,
something very underused in training. This
will lead to increased neural connection
with the muscle, better synchronization
between motor units, increased activation of
the contractile parts and less inhibition by
the muscle safety mechanism, the Golgi
tendon.
As an avid trainee you are most certainly
aware of the difference between Type II and
Type I muscle fibers, and know that Type II
fibers have the highest potential for
hypertrophy. When stimulating these fibers
you need to keep them under tension for
about 20-60 seconds, whereas the lower
spectrum trains the Type II b and the higher
the Type II a. So as you can see you need to
incorporate heavy weights and low reps as
well as higher reps with medium weight to
achieve a complete development.
Another thing that increases muscle
activation is the stretch shortening cycle
and this is also a very underused and
misused method in weight training. Let me
give you an example: When performing a flye
for the chest some people tend to keep their
arms straight, which will actually lead to
an increased activation of the biceps –
which in turn will take away load from the
chest! So it is VERY important to keep your
arms slightly bent and still during this
flye movement. Correctly used the stretch
shortening cycle will make your workout even
more productive.
You often hear people complaining about not
being able to make a body part grow, no
matter how hard they try. When you take a
closer look at them you often see that one
or more muscles in the near region working
as agonists are “over” developed, while the
targeted muscle itself is lagging. Now the
reason for this is likely that the
antagonistic muscle has a lower excitation
threshold, which is often the case. This
means that it will act prior to the other
muscles in the movement. To minimize the
chance for this happening you could try
stretching the more reactive muscle before
training in order to inhibit it slightly.
After stretching a muscle it will weaken a
bit for a short period which in turn will
lead to a better activation of the targeted
muscle.
You can also stretch the antagonist muscles,
the ones doing the opposite motion, to
decrease the risk of reciprocal inhibition.
Ok enough of the mumbo jumbo and let’s get
down to business and use what we just
learned. One way is to begin with a phase of
more strength oriented training and to
follow it up with a more conventional
bodybuilding phase. Or you could mix them up
like in the following template. The carry
over from the strength oriented set will
lead to the possibility to use a heavier
weight than you normally would be able to do,
thanks to the activation of the nervous
system, as stated above.
Before weight workout do the following:
Stretch: Front shoulder, biceps, external
rotators, rear shoulder, lats and triceps.
You can also stretch these muscles in
between sets.
Chest program based on once a week chest
training (For people with good recovery it
can also be done once every five days):
Each pair of exercises is done as a
superset, only with the prescribed rest in
between.
A.1. Incline dumbbell press, with a “twist”
(when lowering the dumbbell let your
forearms slightly fall out to change
leverage and put more stress on your
pectorals, and avoid extending your arms
entirely at the top, to keep tension up.) 3
sets x 2 reps with 90 seconds rest. (When
going for hypertrophy you are supposed to
have some oxygen debt.)
A.2. Incline flyes, done with cables for
maximum tension and range of motion – try to
use as much muscle as possible instead of
cheating with momentum when moving the
weight. 3 sets x 45-50 seconds with 90
seconds rest.
B.1. Flat dumbbell press, see above for
performance instructions. 2-3 x 2 with 90
sec rest
B.2. Flat flyes with cables. 2-3 x 45-50s
with 90s rest.
Done right this will produce an incredible
pump, and some serious soreness the next few
days.
You should be aware of the fact that it only
takes so long for the body to adapt to any
kind of program so you should change it
regularly, even if it feels good. For the
average trainee I would suggest never to
stay with a program for more than 8 times
before changing it. If you are more
experienced you might even change after 4
times! You ladies out there can use the 8
rule even being more routined, according to
my experience a female can stay longer on a
program without stagnating as much.
Try this out and feel free to change things
around, using the information above.
Train Your
Assets!!
Posted August 16th, 2007 on myfittribe.com
I just finished looking through some
pictures from a Fitness contest, and as the
man I am I was of course looking at the
derrière of the ladies. - Oh come on ladies
you stare at ours to! The one thing that hit
me again, as it always does, was that even
where the contestants had well developed
glutes and hams and had a low percentage of
body fat, they very often still lacked that
great glute/ham tie-in. The gluteals fold
where too prominent in many cases. (The
gluteal fold is the fold between the gluteus
maximus and your hamstring to clear things
out for those who need to be enlightened.)
Of course you can look great anyways, but if
you are already setting aside a substantial
amount of time on training, then why not use
some of it in order to “correct” this minor
imperfection?
I find that this is a problem more commonly
occurring with athletes lacking a genuine
athletic background, while the ones with the
least problems are former gymnast and track
and field athletes. For me this is not a
surprise as both of these groups have a
history of having done a lot of sprint type
training. The kind of training that will put
your hams and glutes to work in synergism
during hip movement, the way they are
intended to in the first place.
So you guessed it!? When a fitness
contestant comes to me for help with this or
to get ready for a show, sprint training is
the order of the day!
Not only does it improve your glute/ham
tie-in it also does the following:
Improves neuro – muscular connection
Balances out Quad/Ham imbalance
Increases EPOC, which will lead to greater
fat loss
Strengthens your core
A word of caution first! If you are
inexperienced or have been off-season from
this type of training for a long time,
please ease into it. Start with doing only
one part of the program to begin with and
then slowly add to it. And to all of you –
please warm up properly! I am going to share
with you a little secret here to get even
more out of this, which in turn will even
add to your progress in the gym when
training hams and glutes.
- Stretch your hip flexors thoroughly before
the session! This to ensure your ability to
use your glutes and hams to the max, as
shortened hip flexors is another reason for
poor glute/ham tie-ins – but that is for
another article…
So let’s go to work. You will start of with
the 40 yard dash in a slight up-hill; this
is to engage even more glute/ham involvement.
You should start with 5 sets and gradually
build up to 10 sets and keep your rest
periods at 75-90seconds - we don’t want
complete recovery but at the same time you
need to be able to run at near maximum speed
at every set!
A short note about form here, try to stay as
erect as possible when sprinting and use
your legs to drive you forward. If you need
a more thorough explanation on how to
sprint, please just contact me.
After about a 180 seconds worth of rest it
is time for the famous Borzov jump. For
those few of you who don’t now about this
movement read on, you happily few who do, go
to the progression for it right away.
The Borzov jump
The Borzov jump is a great exercise for
developing explosive power. Technically it
should be called a hop rather than a jump
being a single leg exercise, but we have
always called it a jump and will continue to
do so.
Legend has it that the exercise was used by
the great Valery Borzov, the Russian
sprinter who won Olympic gold for his
country in the 100m. The strength of the
exercise lies in the fact that it involves
so many movements that assist with speed and
agility development.
And for those of you who are after muscle
development it includes ankle extensions for
the calves, knee extensions for your quads,
as giving your glutes and hams a heavy
challenge by all those hip extensions.
However, it is a relatively advanced
exercise, and is suitable only for those
with at least one year of plyometric
training, so I strongly suggest that you use
the progression I lay out for you.
Progression
Level 1
Just perform a rapid single leg squat, with
the same action as the Borzov jump but
without leaving the ground (2-4 sets of 6-12
reps for each leg, with a 75-90 sec rest.)
Level 2
As above, but only perform a half effort
jump into the air, just slightly drawing the
knee up to the chest (set and reps as above)
Level 3
Do the full Borzov jump as seen above, but
with a rest in between each rep (set and
reps as above)
Level 4
Continuous jumps as seen above (4 sets of
4-8 each leg and you will really know about
it!)
And for the finale, hurdle jumps. Space out
5 hurdles with enough space in between them
to be able to jump freely up and down over
them, without hitting your knees in the
hurdle or dragging the hurdle with you when
trying to get over it! Set the height of the
hurdle at a height that challenges you. If
you are unsure just set it a little lower
and work your way up from there. Perform 2
rounds of 2-4 sets with 75-90 seconds rest.
For you out there who train for speed and/or
to improve your jumping ability, this is not
the program for you! This is a
bastardization of track training to improve
amongst other things the glute/ham tie-in.
But for you who are willing to give this a
try, it might even give you a chance to show
off your assets, while sprinting away from
the competitors..!
Everything (and we mean EVERYTHING) you want
to know about warming up!
Posted September 5th, 2007 on myfittribe.com
I was actually about to write an article
series for you on how to construct the
“Viking warrior” athlete the way we do it
here in Sweden. But after having dropped my
jaw a couple of times too many last week
while observing people warming up in the
gym, I felt forced to write an article on
how to do it in a proper way. So here it is
my fellow tribe friends.
We all know that we should do some kind of a
warm-up before we start to exercise. Even so
a lot of people get to it without actually
having a clue on what, why and how to do so
in order to get the most out of the workout.
Usually they start out with some kind of a
light aerobic exercise, on the treadmill or
the bike, to follow it up with some light
static stretching at the most, before they
head into the gym. Or maybe they are doing
my favourite- I just love the one where 50
fast reps are being banged out on the
exercise of choice, like an epileptic
penguin wobbling around! As a preparation
before attacking the real weights
But if you ask me it’s like hunting for
rabbit with a cannon, you know you have to
use something but aren’t sure about what.
A correctly performed warm-up can lead an
exceptional workout instead of a mediocre
one. So it deserves your full focus and at
least some good effort- it may even prolong
you career as an athlete if you do it right!
The information I am going to share with you
is actually the same kind I use on my top
level athletes. If I say Sydney, Athens and
Beijing you know which level I’m referring
to.
But let us first repeat some basics before
going into details. What is the actual
function of a warm-up, what use will you
have from it? Generally speaking it is to
prepare your body for the coming workout or
task at hand, and to help it perform
optimally, hereby:
Raising your body temperature
Raising the heart beat
Improving your nervous systems impulses (coordination
and reaction time improves amongst other
things)
Increasing your muscle flexibility
Lubricating your joints
Facilitating your muscles
Improving your proproception
Preventing injury
In addition the warm up is also a perfect
time to gauge your daily form and perhaps
make some last minute changes in your
workout program accordingly.
Ok back to the “perfect” warm-up. What does
it look like? Let’s break it down into three
stages:
Increasing body temperature
Dynamic stretching
Transition
1. Increasing body temperature
If possible I would recommend you to start
your warm-up with skipping rope. It is easy
to bring along and it is cheap, so there
should be no problem to get one or use one.
Also, by skipping rope you train your
reactive strength, which puts you a
foundation for the coming plyometric
training.
And by judging your timing and coordination
while skipping, you can also overview the
condition of your nervous system at that
time. If you fumble around and have bad
timing while jumping and turning the rope
(and I don’t mean by the reason of you being
an inexperienced rope-skipper), then you may
need to make some wise last-minute changes
in your workout or warm-up program. Since
bad coordination may be an indication of
your body not being fully rested and/or you
being on your way to overtraining.
I would suggest for this part to take about
5 minutes, or until you break a sweat.
2. Dynamic stretching
The Dynamic stretching part of the warm-up
is the most important one of all, partially
because it puts the foundation for your
flexibility as well as improving your
coordination, balance and re-activation of
shut-off muscles. I will return to this in a
while.
Many choose to do static stretching here
instead of dynamic. I would not say it is
entirely wrong if it is done so for any of
the following reasons:
to stretch the antagonistic muscles to the
one you are about to train, which can
actually improve your workout even more.
to stretch specific muscles due to rehab.
I also often recommend static stretching for
the beginner who may have some difficulties
coordinating simultaneous movements.
But primarily I use static stretching after
a training session, and if possible,
separated from the actual workout. Now I
know this is hardcore but if you want to get
the absolute most out of your static
stretching you should perform it in about 4
hours following a strenuous workout, by
which time your nervous system is back into
“normal”.
By performing dynamic stretching I’m going
to increase my flexibility, lubricate my
joints and strengthen my muscles in their
full range of motion. This is highly useful
in all sports, both as injury prevention and
as a performance enhancement.
This part also activates muscles that
usually may be shut-off due to years of
inactivity. A common muscle to often shut
off or become inactivated is the Gluteus
Maximus or your butt, even amongst elite
level athletes - believe it or not. Try the
following: Stand up with your feet together
and then try to squeeze each one of your
buttocks one at a time. Did you succeed?
Congratulations! If you did not, then don’t
worry, you are amongst friends! Most people
who try this tend to squeeze both buttocks
at the same time. By learning to activate
these powerful muscles more effectively you
are going to improve your performance. Now
how come?
The reason why we have a hard time using our
gluteals effectively is because of our hip-
flexors often being shortened by, amongst
other things, way to much sitting down
during the days – at work, at home with
Oprah or Dr Phil and even at the gym – but I
am saving that for an other article. This
leads to inhibition of the gluteals by the
neural connection between the two muscles,
in a fancy way called reciprocal inhibition.
This simply means that while one muscle
fires the other one is reloading, in this
case the gluteals are constantly reloading.
When performing the dynamic stretching
correctly you will teach your body to
function correctly again.
When doing this part of the warm-up I want
you to successively increase the range of
motion in the exercises - but never force
yourself, this will only lead to
counterproductive results. It is also of
importance that you engage the antagonistic
muscle and not only use the momentum to do
the work for you. I also suggest you use a
broom shaft to gauge your posture. To get
the most out of this part you should always
strive after “perfect posture”, because if
not your joints and muscles will not work in
perfect synchronicity!
3.Transition
Now you are ready for the last phase, the
transition. This phase prepares you directly
for the work to follow. Let’s say you are
about to Squat, just simply perform this
exercise with progressively higher load, (a
note here - don’t use high reps, 6-8 are
plenty. Too many reps may lead to locally
increased lactic acid production, which in
turn prevent you from using your type II
muscle fibres in their fullest! Not good if
your goal is strength and mass!), while
doing this take the opportunity to perfect
your form.
To summarize
Skipping rope or use the bike or treadmill
if necessary
Do dynamic stretching of the muscles you are
about to train
Progressively use higher loads on the
exercise you are about to do
As mentioned earlier this will prepare your
body and enhance its ability to perform at a
higher level. So do as my coming
participants in Beijing, put some serious
focus and effort into the warm-up!

Konditionsträning för kampsport – Hur man ”bäst” förbereder sig konditionsmässigt för en match!
Tillhör du dem som fortfarande tror att det bästa sättet att förbättra din kondition för kampsport är att ge dig ut och långlöpa? Det är inte ovanligt att jag träffar på tränande som kör löpning 3-4 ggr i veckan i tidsperioder på 30-60 minuter per gång för att förbättra sin kondition inför en match. Tanken är väl i och för sig rätt men resultatet blir inte optimalt! Och lägger man ner fyra timmar i veckan så vill man väl gärna ha lön för mödan?
Innan vi går vidare vill jag bara att du tänker efter: Hur ser en match ut? Består den av en enda lång rond där du hela tiden jobbar på samma intensitetsnivå eller är den uppdelad i perioder av lugnare och intensivare arbete? Jag tror att svaret är ganska självklart! En match är indelad i perioder med olika intensitet och har ofta vila mellan ronderna!
Nu till lite kort och grundläggande fysiologi. Alla personer har en fördelning mellan långsamma och snabba muskelfibrer. Fördelningen beror bland annat på gener och träningsmetoder.
De långsamma, även kallade Typ I, är de fibrer som tränas vid distanslöpning och liknande uthållighetsaktiviteter. När du använder dig av träningsmetoder där du ligger och arbetar på samma intensitetsnivå under tidsperioder på över 30 minuter, kommer du att använda, utveckla och rekrytera denna muskelfibertyp med dess hjälpande enzymsystem.
För den oinvigde kan det vara helt naturligt att ge sig ut och löpa eller ställa sig på trappmaskinen i en timme för att nå det uppsatta målet – förbättra konditionen. Problemet är bara att denna typ av träning även påverkar förmågan att explosivt använda benen. Denna typ av träning av de långsamma motoriska enheterna medför en nedsatt förmåga att generera explosiv kraftutveckling och anaerob uthållighet! Du blir uthållig och seg men tappar förmågan till snabba explosiva rörelser.
Vid kontinuerlig konditionsträning kommer du också att öka antalet mitochondrier i dina muskelceller. Mitochondrierna är enkelt förklarat cellens kraftverk som hjälper dig vid långtidsarbete. Problemet är bara att när dessa utvecklas sker det till viss del på bekostnad av de snabba muskelfibrerna och deras anaeroba enzymer.
Som kampsportare krävs att du gång på gång kan utveckla maximalkraft och explosivitet, inte förmågan att kontinuerligt vifta bort dina motståndare eller försöka springa ifrån dem! För att kunna göra det krävs att du utvecklar dina snabba muskelfibrer och förmågan att gång på gång kunna aktivera dem. Man skulle kunna jämföra med en sprinter och en maratonlöpare. En maratonlöpare kommer aldrig att prestera bra på 100meter och en sprinter kommer heller inte att prestera bra på ett maraton!
Men hur tränar vi då bäst för att kunna utveckla så mycket kraft som möjligt och höja vår förmåga att stå emot mjölksyra?
För att utveckla dessa komponenter ska du, som du säkert redan gissat, begränsa din aeroba träning och fokusera på träningsmetoder som gynnar dina snabba muskelfibrer och ditt anaeroba system.
Självklart har du en viss nytta av aerob träning, men det skall inte utgöra huvuddelen av din träning, jag skulle rekommendera dig att använda dig av det under en grundträningsfas, för att sedan ändra din träning till mer explosiv när du närmar dig tävlingen.
Hur ändrar du då på träningen för att få ut så mycket som möjligt av den?
Tänk igenom hur din match ser ut! Hur många ronder har den, hur lång tid pågår varje rond och vari ligger din styrka respektive svaghet – är jag stark men saknar uthållighet eller är jag ”svag” men har god uthållighet?
Ha de faktorerna i åtanke när du bygger upp ditt träningsprogram inför en föreliggande match! I mitt tycke är intervallträning den typ av träning som konditionsmässigt är bäst relaterat till själva matchsituationen. När man tränar intervaller så varvar man perioder av högintensivt arbete med lugnare återhämtningsperioder
Problemet här är att en del går helt överstyr när de designar sitt träningsprogram. Du har ingen nytta av att överdriva på något sätt; skulle en 100 meters löpare lägga sina intervaller på 1000 meter? Skulle inte tro det! Lägg den tiden på annat i stället, som teknikträning och övrig träning – kom ihåg att en dålig teknik kommer att kräva mer energi och göra dig tröttare, så satsa gärna på den!
Tänk på att när du utför dina intervaller skall det vara kvalitet före kvantitet, du kommer alltid att få tillbaka det du ger.
För att få lite hum om hur det kan se ut ska jag ge två exempel på upplägg.

men behöver bättre korttidsuthållighet.

Som du ser, så för att utveckla styrka och snabbhet använder du dig av intervaller som är aningens kortare än rondtiden och tvärtom för att utveckla uthållighet!
Som komplement till intervallträningen kan du som tävlar och har din disciplin indelad i ronder också se till att din styrketräning förbättrar förutsättningarna för din lokala uthållighet. Den lokala uthålligheten är den uthållighet som du har exempelvis i armar och skulderparti till skillnad från den centrala som är hjärta och lungor. Genom att använda lätta vikter och explosivt utföra upp till 20-25 repetitioner med kort vila mellan seten förbättrar du din förmåga att repetitivt kunna utföra sparkar och slag under en match. Självklart har du lagt din bas av styrka (se tidigare artikel om hypertrofi), innan du använder dig av denna typ av träning!
Tillhör du dem som tidigare ägnat allt för stor tid åt distanslöpning kanske du kommer att sakna den positiva känslan du fick av alla de endorfiner som är associerade med distanslöpning. Men du kommer snart att glömma dessa när du känner hur din kraft och styrka ökar och när du står där som vinnare!
Repetitioner, hur många ska jag göra och varför?
De flesta tränande utför 8-12 repetitioner per set oavsett övning (förutom magen som man gärna tränar med fler repetitioner – det verkar som myten om punktförbränning fortfarande lever kvar). Detta gör man oftast utan någon som helst fundering om varför. Det verkar nästan som om antalet reps vore en rekommendation från något statligt verk (kommer ni ihåg 6-8 skivor bröd per dag?). Men för att effektivt träna sina muskler måste man förstå följande; muskler räknar inte repetitioner utan känner bara av en belastning under en viss tid.
Muskelanspänning som bibehålls under en specifik tidsperiod skapar de kemiska reaktioner i muskeln som ger dig de förändringar du är ute efter och precis som i kemilabbet så får man olika reaktioner beroende på vilka ”ingredienser” eller stimuli som man tillför. Ju högre belastning desto kortare tid klarar man av att genomföra ett set. Den tyngsta vikt du kan lyfta (1 repetition max) ger den högsta muskelspänning du kan generera, koncentriskt dvs. att det på grund av fysiska och kemiska orsaker är omöjligt att generera den spänningen under en längre tid. Om muskelns anspänning däremot är låg, som vid aerobiskt arbete, kan man i vissa fall utföra en övning i flera timmar.
För de flesta tränande som är ute efter att få lite mer muskler, lite mer styrka och lite mindre fett bör musklerna vara under belastning i 40-60 sekunder till eller till dess att man nästan uppnår utmattning. Om man räknar med att varje repetition tar ca 4 sekunder så skulle det krävas ett set på 10-12 repetitioner för att komma upp i 40-60 sekunder. Det är denna teori som det vanligen rekommenderade antalet repetitioner (8-12 stycken) grundar sig i. Om man däremot ändrar på tempot på repetitionerna så att man antingen utför dem snabbare eller långsammare så får man ett annat resultat. Man kan variera antalet repetitionerna och tempot på olika sätt så länge som man håller oss inom den ovan nämnde tidsperioden. Det är alltså bättre att koncentrera sig på repetitionerna än att bara köra igenom setet så fort som möjligt. Resan genom setet är viktigare än slutmålet!
Vid högrepetitionsträning (12 repetitioner eller fler per set) är det dock viktigt att repetitionerna inte utförs för långsamt. Det är nämligen så att musklerna innehåller både långsamma, Typ I fibrer och snabba Typ II fibrer. Hos en normal person är det ca 50 % av varje typ i musklerna med viss variation från person till person och mellan olika muskler. De intressantaste fibrerna för de som vill öka i muskelmassa är de synliga Typ II fibrerna som har störst tillväxtpotential. Det är viktigt att tänka på att om man tränar under för lång belastningsperiod så kan man inte använda tillräcklig tung belastning för att stimulera dessa fibrer och då uteblir muskeltillväxten.
Det kan också vara intressant att känna till att de Typ II fibrerna har en tendens att minska med åldern, vilket leder till minskad ämnesomsättning och därigenom en ökad fettmängd. Man bör alltså träna med 40-60 sekunders belastning för att bibehålla musklerna och öka ämnesomsättningen.
För att återknyta till fördelningen av muskelfiber mellan olika muskler kan det vara intressant att känna till följande:
Exempel på muskler som är Typ II dominanta (eller mestadels snabba muskelfibrer) är gastrocnemius, (yttre vadmusklen), hamstring, triceps och raka bukmusklerna (och ändå tränar de flesta dessa som de vore Typ I dominant med högrepetitionsträning) .
Muskler som är Typ I dominanta är exempelvis soleus, (djupa vadmuskulaturen, och transversus abdominis, (din djupliggande muskelkorsett).
Enkelt uttryckt kan man följa regeln att när man tränar för att stimulera Typ II fibrer så bör man ha en belastning med vilken man kan genomföra ett set på 20-60 sekunder och när man tränar Typ I fibrerna så bör man ligga på en belastningsperiod på 50-90 sekunder.
Alltså, tänk efter hur du vill träna dina muskler och lägg upp din träning utifrån det. Låt det inte bli en gissning! Uppskatta din belastningstid per set och beräkna din normala repetitionstid. Räkna sedan ut hur många repetitioner du bör göra. Detta kommer att göra att du optimerar varje set och din tid i gymmet. Lycka till!

Hur du kan använda mer muskler, bränna mer fett, använda din mage, ländrygg och lårmuskulatur på samma gång genom att göra en enkel förändring i din träning.
Varför sitter folk ned när de lyfter vikter? Låter nästan som en motsats, eller hur? Många svarar att det är så de har lärt sig att göra, att det är säkrare och mer effektivt. Effektiviteten skulle ligga i att du mer isolerat kan träna den muskel du vill komma åt, vilket till en viss del kan vara rätt!
Att sedan de flesta maskiner är byggda så att du är tvungen att sitta gör det naturligt att ta med sig denna vana (ovana?) till andra övningar.
Om vi går tillbaka till att det skulle vara effektivare för att isolera muskeln när du sitter ned, låt oss då fundera över om det är vårt primära mål och om det bör vara det. Är du bodybuilder eller ”bara” tränar för att se bra ut då kanske det är rätt. Men om du tränar för att bygga funktionell styrka och må bra då finns det bättre sätt.
Exempelvis så har man sett samband mellan svag multifideusmuskulatur, små muskler närmast ryggraden, och transversus abdominis, djup magmuskel, och ländryggsproblem. Visste du att genom att använda dig av stående övningar kan du träna dessa muskler effektivt, och att sittande varianter av dessa övningar nästan inte tränar de musklerna alls!?
En viktig sak att notera är också att transversus abdominis (TA) är den första muskeln att aktiveras vid de flesta rörelser av armar och ben, i varje fall hos friska människor utan ländryggsproblem.
Detta betyder att om du inte använder dig av din TA, kan du skapa ett felaktigt rekryterings- mönster när du spänner musklerna, dvs. dina muskler kommer inte att arbeta i rätt ordning och med den timing som krävs för koordinerade, säkra och effektiva rörelser.
Så om du tränar för att förbättra prestationen utanför träningslokalen bör kanske sittande övningar och maskiner användas sparsamt. Sittande övningar och maskiner fyller sitt syfte när det gäller att komma åt den huvudsakligt tränande muskeln men gör inget eller lite för de stabiliserande musklerna, både kring leder och i bål. Det är dessa små muskler som du alltid kommer använda ihop med de primära musklerna i det vardagliga livet, typfall när du bär hem matkassarna.
Så om du tränar övervägande sittande och i maskiner så kan det bidra till att skapa obalanser i styrka mellan dessa muskler, vilket kan leda till skador.
En led är enkelt förklarat det ställe där två ben möts. Benen hålls på plats passivt, med hjälp av ligament, och aktivt, genom muskler. För att leden skall fungera optimalt så måste de primära och de stabiliserande musklerna arbeta samstämt. Om stabilisatorerna inte är proportionellt starka till de primära musklerna, eller om du har lärt dina muskler att arbeta utan dina stabilisatorer på grund av att du överanvänt maskiner och sittande övningar i din träning, kommer dina leder inte att kunna fungera normalt.
Leder som inte rör sig naturligt kommer att lägga belastning på strukturer som inte är gjorda för det, vilket leder till överbelastningar, och i längden inflammationer och ledförslitningar. Om dina primära muskler är för starka jämfört med den stabiliserande muskulaturen kommer detta att orsaka att mekaniken i leden förändras.
Alla känner inte heller till att du utsätter din ländrygg för mer belastning när du sitter ned än när du står. När du sitter ned med naturlig kurvatur och utan belastning så ökar disktrycket i ländryggen med ungefär 40 %. Om du dessutom lutar dig framåt kan denna stress öka med så mycket som 90%.
Belastningen blir mycket större när du lägger till viktbelastning, speciellt om du använder dig av ryckiga rörelser vid start och/eller slut. Att belastningen på ryggraden ökar beror på att när du sitter kan du inte absorbera belastning genom att böja på knän, höft eller vrister, vilket du gör när du står.
Förutom att bidra till leddysfunktioner så kan en överanvändning av sittande övningar skapa ett felaktigt rörelsemönster. Sittande övningar tränar de primära musklerna att arbeta utan de stabiliserande musklerna i kroppen. Detta kan bli som ett automatiskt rörelseprogram, ett program som du använder dig av utan att tänka på det.
Din hjärna arbetar inte med muskler utan med rörelser. Om du tränar din biceps i en enarms curlmaskin, till exempel, kommer din hjärna att programmera in denna rörelse och dess sekvenser. Så när du ska arbeta med din biceps i verkliga livet så kommer din hjärna att referera till denna rörelse. Vilket kan leda till skador när du skall lyfta en väska eller en påse på grund av att du inte tränat din arm att fungera ihop med din bål.
Stående övningar är helt enkelt mer funktionella, när var sista gången du lyfte något tungt när du satt ned? Oftast när du skall lyfta något tungt så reser du dig upp så du kan använda dina ben och din bål ihop med armarna, så varför inte träna så då?
Vill du träna din mage mer och eller dina lårs ”insida” eller ”utsida”? Enkelt - ställ dig upp när du tränar! Maskiner är utmärkta att ta till när du vill isolera en muskel men vill du träna för att fungera optimalt bör du ställa dig upp och träna!
Har du sett de på gymmet som är stora som hus men inte lyfter vikter som är mycket tyngre än de du använder?! Eller har du kanske sett det omvända - tränande som inte är mycket större än du men som använder vikter som
är TUNGA. Detta är egentligen inte så konstigt som det kan verka utan beror ofta på hur den aktive tränar. Att jag skriver ”ofta” här beror på att man aldrig helt kan bortse från den genetiska faktorn, alternativt ”avancerade kosttillskott”
Även om två tränande har tillsynes liknande fysik kan det finnas stora skillnader i den fysik de har byggt på grund av olika träningsmetoder. Med andra ord: all muskeltillväxt sker INTE på samma sätt.
Det finns två väldigt olika typer av muskeltillväxt/hypertrofi, vilka stimuleras
av helt olika slags träning. Detta ger svar på frågan varför vissa är så starka som
de ser ut och vissa är bara ”All show, no go”.
De två slagen av muskeltillväxt är:
1.sacoplasmatisk- och
2.myofribrillär hypertrofi.
Sarcoplasmatisk hypertrofi
Sarcoplasmatisk hypertrofi är en ökning av volymen i den icke kontraktila muskelcellvätskan, sarcoplasman. Denna vätska utgör ca 25-30 % av muskelns storlek. Även om muskelns tvärsnitt ökar så kommer muskelfibrernas täthet per enhet minska, och själva styrkeökningen blir försumbar. Denna slags hypertrofi är ett resultat av högrepetitionsträning av
bodybuildingtyp.
Ett av de vanligaste felen jag som tränare kan bevittna är överanvändning av denna typ av träning inom idrottsgrenar där kraft och explosivitet spelar en avgörande roll. Ofta tränar idrottarna efter ett program som föreskriver 10-15 reps. Visst har även det sin plats i träningsprogrammet, men skall inte utgöra
huvuddelen av träningen, om målet med denna är ökad kraft och explosivitet .
Visserligen kan även idrottare inom explosiva grenar uppleva vissa fördelar genom en
ökad massa; exempelvis kan en hockey spelare som lagt på sig något extra kilo muskler
klara av en smäll eller stå emot tacklingar bättre. Det kan också vara bra att ha lite
”i reserv” under en säsong för att motverka alltför stor förlust av muskelmassa,
eller att inleda träningen direkt efter säsongen med en högrepetitionsperiod för att
fortare återfå den muskelmassa som gått förlorad under säsongen. Vissa studier pekar också på att en större muskel kan ha bättre förutsättningar för styrkeutveckling vid påbörjning av träning för maximalstyrka.
Det viktiga här är dock att ha i åtanke att denna typ av muskeltillväxt har väldigt lite att göra med sådana explosiva moment som hopp, löpning, kast och slag. Detta är anledningen till att bodybuilders, vars träning huvudsakligen stimulerar tillväxten av typ IIA muskelfibrer och orsakar hypertrofi av de icke kontraktila komponenterna av muskel, inte är de snabbaste eller starkaste av elittränande. Detta trots att de generellt har mer muskler än andra aktiva! Jag anser att denna typ av hypertrofi gynnar mer utseende än funktionalitet.
Myofibrilär hypertrofi
Myofibrillär hypertrofi, å andra sidan, är tillväxt av muskelfibern genom en ökning av antalet myofibriller, dvs muskelfiberns byggstenar, vilka kan kontrahera och skapa spänning i muskeln. Med denna typ av hypertrofi ökas densiteten av myofibriller och därmed ökar även förutsättningen för utveckling av muskulär styrka. Detta uppnås bäst
genom träning med tunga vikter och få repetitioner.
Om man tänker på följande så får man en bättre bild av vad som krävs inom en hel del idrotter; det tar mindre än en sekund att slå ett slagskott, ett slag i boxning eller att hoppa på en retur i basket. Att utföra 1 RM tar ca tre sekunder& Som du ser är många idrotter explosiva i sin natur. Det är därför viktigt att dessa kvaliteter tränas på rätt sätt! Genom att använda sig av en repetitions mängd på 1-5 reps, träning för maximal styrka, så kommer du också att träna ditt nervsystem, vilket ofta är en bortglömd del av träningen. Den här typen av träning resulterar i en ökad neural transport till muskeln, ökad synkronisering av motoriska enheter, ökad aktivering av den kontraktila apparaten och minskad hämning av muskelns skyddsnät, Golgi senorgan. Den stimulerar tillväxten av de riktigt snabba muskelfibrerna typ IIB, vilket i praktiken innebär att rätt använd vid rätt tillfälle så kommer träning som leder till Myofibrillär hypertrofi utan tvekan att öka din förmåga att generera kraft och snabbhet. Det är vad jag kallar funktionell hypertrofi.
Sammanfattning
Även om man inte kan se på en person hur han tränat för sin massa, så kommer det att märkas så fort han eller hon ska använda sina muskler. Som atleter tycker jag att vi skall försöka undvika att falla in i 3 x 10 reps-tränings-slentrianen. Det är alltid syftet med träningen som skall diktera det sätt du väljer att träna på, inte vanan eller det som de andra tränar. Detta kanske betyder att du skall använda båda typer av träning i ditt upplägg, beroende på mål som sagt. Men kom ihåg att hur mycket det än bränner när du kör ditt högrepetitionsset på bensparken så kommer de inte att bygga den styrka, kraft och funktionalitet som ett set tunga benböj gör!
