| ABSTRACT | |
In this article we are going to look at the various components of fitness (aerobic/anaerobic) that are involved in combat sports as well as a brief overview of muscle fiber types and energy systems to help combatants put together effective training programs specific to their needs. |
|
| When we look
at increasing our level of fitness, we tend to think about heart/ lung
function (the cardiorespiratory system). The lungs being able to take
in oxygen, the heart being able to transport oxygen around the body to
the working muscles then gathering carbon dioxide for the return journey
back to the lungs where it is expelled. When improving heart/lung function
we look at increasing the strength of the heart muscle so that it can
expel more blood with each contraction (stroke volume) and in turn circulate
more blood and oxygen around the body to the working muscles. Although
heart/lung function is a very important component of fitness, activities
that require strength and power (working at higher intensities) require
more than heart lung function for muscle fibers to be able to continually
apply force at maximal or near maximal intensity. The main characteristics of these fibers are they are red in color due to their high concentration of blood capillaries, this results in greater blood supply and in turn greater oxygen supply to the working muscles. Type I fibers are able to contract for long durations at low to medium intensities. Type II Fibers (Fast Twitch Fibers) The main characteristics of these fibers are, they are white in color as they have lower concentrations of blood capillaries than type I fibers and they are able to contract at higher intensities over shorter durations. Our type II fibers can be broken
down into two sub categories. Applying Force When our muscles apply force
for any activity, our nervous system firsts recruits our type I fibers.
If the intensity of the force required to complete the activity is low,
then our type I fibers will be sufficient. Muscle Fiber Types & Genetics Our genetics will largely determine
which sports we will excel at. You’ll find that athletes that have
higher percentages of “slow twitch” muscle fibers are more
likely to excel in long distance endurance events such as triathlons and
marathons, where as athletes that have higher percentages of “fast
twitch” muscle fibers are more likely to excel in strength and power
dominated sports such as discus, high Jump, 100 meter sprint, weightlifting
etc. ATP is always present in your
muscle cells – and indeed in all the living cells in your body;
without it your cells would quickly stop working and die. Because it supplies
energy to all cells, ATP is often called the universal energy donor, but
a better label would be the body’s “primary energy currency”. AEROBIC ENERGY SYSTEM Our type I fibers are largely
fueled by our “aerobic energy system”. LACTATE ENERGY SYSTEM Our type IIa fibers are largely fueled by our “lactate energy system” and burns carbohydrates as fuel (glucose + ADP = lactic acid + ATP). Our intensity is medium to high which means our body can’t supply enough oxygen to maintain the second phase of our aerobic energy system (lactic acid will no longer be metabolized as quickly as it is being produced), resulting in an accumulation of lactic acid, eventually blood lactate levels will rise to levels where our intensity can no longer be maintained. ATP – PC ENERGY SYSTEM Our type IIb fibers are largely
fuelled by the “ATP-PC energy system” and like our “lactate
energy system” it burns carbohydrates as fuel without the presence
of oxygen, however no lactic acid is produced when solely utilizing the
“ATP-PC energy system” (PC + ADP = ATP + creatine). If the intensity of our training stays constant and at a level to solely utilize our “aerobic energy system”, at a level where we are burning predominately carbohydrates we would generally have enough fuel for 60-90 minutes of training. If the intensity of our training stays constant and at a level to solely utilize our “lactate energy system”, we would have enough fuel to last 45-60 seconds of training. If the intensity of our training
stays constant and at a level to solely utilize our “ATP-PC energy
system”, then we would have enough fuel to last 6-8 seconds of maximal
effort. Recovery of Energy Systems Our carbohydrate stores used to fuel our “aerobic energy system” will take approximately 24-36 hours to fully recover if they have been depleted, this may occur in a 60-90 minute training session that consist of medium to high intensity work loads. The likelihood of competing in combat over duration of 60-90 minutes is very small these days however it still occasionally happens (Royce Gracie v Kazushi Sakuraba May 2000 “Pride Fighting Championships”, fight went for 6x15 minute rounds). Our “lactate energy systems”
recovery is more dependent on our bodies ability to remove lactic acid
as apposed to replenishing fuel stores for muscle contractions. When it comes to training there
are three methods we can use to bring about the biological changes needed
to apply force optimally. 1) Continuous training is training that is low to medium in intensity and usually done over a medium to long duration (30-180 minutes). This type of training would utilize your aerobic energy system e.g. Long distance running, long distance swimming, long distance cycling etc. FARTLEK 2) Fartlek training is similar
to continuous training with varying intensities. The duration of a Fartlek
session and the intensities reached during bursts of maximal or near maximal
efforts will depend on the requirements of your particular combat, your
current training phase and what you are aiming to achieve in your training
session. Maximal efforts will utilize your “ATP-PC energy system”,
near maximal efforts will utilize your “lactate energy system”.
In between bursts of maximal or near maximal effort you will go back to
utilizing your “aerobic energy system”, which will give your
“ATP-PC energy system” time to replenish (or partly replenish
depending on the duration of your low intensity activity), this will also
give your body a chance to remove some of the accumulated lactic acid.
3) Interval training is made
up of rounds of varying intensities and durations with regular rest periods
in between. The intensity reached, the duration of the rounds and the
rest periods in between rounds will generally depend on the requirements
of your particular type of combat (e.g. how many rounds in a contest,
duration of rounds & rest period between rounds), your current training
phase and what you are aiming to achieve in your training session. The
rest period between rounds will give your “ATP-PC energy system”
time to replenish or partly replenish. The rest period will also give
your body time to remove some of the lactic acid accumulated over the
previous round or rounds. The duration of your particular
form of combat, the intensities reached during combat and the rest periods
between rounds (if applicable) are all contributing factors when looking
at. ATP- PC ENERGY
SYSTEM This training is designed to
generate absolute maximal power. The duration of this exercise is 5-20
seconds. The rest period must be such that a maximal speed effort can
be repeated. Whilst lactic acid will be produced, this training is designed
to minimize its build-up and allow time for its removal. The training
adaptation is likely to be. 1) 25-50% increase in ATP-PC
stores.(This can occur over a 7 month period of specific training 3 times
a week) When applying this form of training to striking Martial Arts you would initially warm up with a specific low intensity warm up of around 5-10 minutes (a warm up that would replicate the type of work about to be undertaken), you would then work on a particular kick, punch or knee strike or maybe a set combination of several strikes on a punching bag, each strike would be addressed with absolute maximal effort/power with no rests between each strike over a 5-20 second interval. You would address a series of intervals (6-10) of around 5-20 seconds each, with rest periods of around 3-5 minutes between each interval. GRAPPLING When applying this form of
training to grappling Martial Arts would initially warm up with a specific
low intensity warm up of around 5-10 minutes (a warm up that would replicate
the type of work about to be undertaken), you would then position yourself
under your opponents “mount” or “side mount”,
then using absolute maximal effort/power to bridge, buck, push and throw
your opponent off you over a 5-20 second interval. You would address a
series of intervals (6-10) of around 5-20 seconds each, with rest periods
of around 3-5 minutes between each interval. This type of training would
be more effective if your opponent was considerably heavier than yourself. LACTIC TOLLERANCE TRAINING This training challenges the
athlete to continue to work at a high to medium intensity during a period
in which lactic acid build-up forces muscle and blood pH down. The likely
training adaptation is a development of “tolerance” to the
low pH by In this type of training, lactic
acid is accumulated during the first part of the effort and "tolerated”
for the latter. An example would be an “all-out” 150-m swim, STRIKING When applying this form of “interval training” to striking, you need to look at the duration of the round/rounds fought in a contest. If your round/rounds were 1
minute in duration, then your training tool would be a near maximal effort
(95%) on the bag for one minute. If your round/rounds were 2
minute in duration, then your training tool would be a near maximal effort
(95%) on the bag for the first 60 seconds, then one would attempt to work
at the highest possible work rate on the bag for the later 60 seconds.
If your round/rounds were 3
minute in duration, then your training tool would be a near maximal effort
(95%) on the bag for the first 60 seconds, then one would attempt to work
at the highest possible work rate on the bag for the later 120 seconds.
When applying this method to
“grappling”, one would ideally work in defense (under your
opponents mount or side mount) with a heavier opponent, as this will help
to increase the intensity. The duration of your training interval would
be ideally 2 minutes where you would work at a near maximal effort (95%)
to bridge, buck, push and throw your opponent off you for 60 seconds,
you would then attempt to work at the highest possible work rate bridging,
bucking, pushing and throwing your opponent off you for the later 60 seconds.
This involves a series of repeats
that are not as fast, nor over as great a distance, as single effort tolerance
work. The effort is still near maximal, but a carry-over of unmetabolised
lactic acid from one effort to the next reduces speed. The lactic acid
levels in the blood typically do not achieve quite as high a concentration
as in “single-effort-induced tolerance work”, but they do
not fall as low between the repeats. STRIKING When applying this training
method to “striking” you need to look at the duration of the
round/rounds fought in a contest. If your round/rounds were 2
minute in duration, then your training tool would be a near maximal effort
on the bag for 2 minutes. GRAPPLING You can apply this method to grappling in which case you would be looking at a similar scenario to the “single-effort-induced tolerance work” for grappling, with 6x2minute rounds of near maximal effort, with 30 seconds rest in between. However there is a form of “Fartlek” training (the lactate stacker), which will have a similar effect to “multiple-effort-induced tolerance work” and is more specific to grappling. THE LACTATE
STACKER STRIKING Because of the problems associated
with high levels of lactic acid, it is recommended that you perform no
more than 2 sessions a week (ideally with 3 rest days between sessions)
where high levels of lactic acid are achieved. AEROBIC ENERGY SYSTEM When looking at training our
“aerobic energy system” to supply fuel for our various forms
of combat, it is very important we apply our principle of training “specificity”. TRAINING METHODS FOR ENHANCING OUR AEROBIC ENERGY SYSTEM THE VELOCITY VO2 MAX SESSION Whether you are an endurance
rower, runner, cyclist, swimmer, skier, or race walker, you can compute
your “velocity VO2 max” by going as far as you can in six
minutes. The pace you establish over this 6-minute period is then your
velocity at VO2 max, one of the most powerful predictors of endurance
performance. Once you have estimated your “velocity VO2 max”,
the workout you should use for “velocity VO2 max” is straightforward:
just warm up and complete 5x3-minute work intervals at your calculated
“velocity VO2 max”, with 3-minute recoveries. The workout
is great for improving “velocity VO2 max”, Lactate threshold
(ANT), efficiency at close to VO2 max paces, strength, power, and psychological
courage and confidence during intense effort. When applying this training
method to striking, we need to slightly change the protocol to make it
more appropriate and specific to striking. Our striker is fitted with
a “heart rate monitor” while the trainer holds the “heart
rate monitor watch”, the striker then goes about striking a punching
bag, ideally in a set rhythm (the idea behind striking in a set rhythm
will help to maintain a more consistent HR). Our goal here will be to
determine the maximal HR that we can consistently maintain over our six-minute
period. This HR will then become the equivalent to our “velocity
VO2 max”. When performing this test it is important that the striker
is adequately rested beforehand (ideally 24-36 hours rest). Once you have
established your training HR, you would go about your 5x3 minute rounds
with 3-minute recoveries. You would complete your training intervals with
your HR monitor on, working at your training HR, your trainer would be
holding your HR monitor watch, giving you constant feed back on your HR.
GRAPPLING When applying this training
method to grappling, we have the problem of finding the appropriate training
stimulus. The above mentioned sports rowing, running, cycling, swimming
and skiing are all close chain sports (no out side influences) therefore
it is easy to consistently maintain a constant pace or rhythm resulting
in a constant HR. Although striking is an open chain sport (outside influences/opponent
that have an effect on your performance) we can take away the outside
influences/opponent and still get a specific training stimulus where we
can maintain a set pace, rhythm, and HR for training (bag work). It is
possible to use a HR monitor when grappling and establish an approximate
training HR, although, even with set drills you would have to question
the consistency of force applied (remembering that your opponent would
also have to apply a consistent amount of resistance) to determine the
maximal HR that you can consistently maintain over our six-minute period.
CYCLING YOUR TRAINING Now we have a better understanding
of muscle fibers, energy systems, the muscle fibers and energy systems
involved in striking and grappling and training methods used to bring
about the biological changes needed for muscles to apply force optimally,
we now need to know how often to train, when to use what training methods,
how much is too much training, how much is too little training, etc. As
well as working on your specific fitness you still need to incorporate
“strength”, “speed”, “power”, “skills”,
“flexibility” etc. To get the right mix and to make sure every
component is addressed properly you need to cycle your training. |
