fibers — the ones used for explosive running.
To achieve a better butt, you need to
work on both the «fast
twitch» and the «slow
twitch» muscle
fibers.
Fast -
twitch muscle
fibers are best trained with higher intensity levels, and since unlike leg curls romanian deadlifts allow you to use heavy weights, this exercise
works great for overloading the hams.
When you exercise with heavy weight and low reps, you are
working on all of your muscle
fibers, both the quick and the slow
twitch fibers, so use really heavy weight that you can only lift a low number of times.
-- Calves are mostly made of slow
twitch fibers and need a lot of
work to make them tired.
The most important reason for this phenomenon is the fact that the brachialis muscle has more slow -
twitch fibers than the biceps, and therefore, has more of a stabilizing role compared to the biceps brachii which is meant for faster, more explosive
work.
«Those people with a genetic predisposition of a high percentage of these
fibers can increase muscle size very easily while the people with a higher percentage of slow
twitch muscle
fibers have to
work really hard to put on mass.»
Fast -
twitch muscle
fibers are used in explosive bursts of power, for example when
working with heavy loads or during sprinting, while slow -
twitch fibers enable long endurance feats such as high - rep sets with light loads or distance running.
Doing daily heavy
work to the point of failure will increase your biceps» capacity for recruiting more fast -
twitch fibers.
For example, if your main goal is to get bigger, doing some speed and maximal strength
work can help to increase the size of your fast -
twitch muscle
fibers and, therefore, help you to gain overall muscle size!
Working on peak power output will help to improve your fast -
twitch muscle
fiber recruitment which plays a huge role in all athletic endeavors that require speed and power.
Performing interval training sessions near lactate threshold can teach your body to decrease the amount of lactic acid being produced and increase lactate removal at any given intensity.At this intensity, the fast -
twitch fibers can be trained to produce less lactic acid and the slow
twitch fibers can be trained to burn more lactic acid, both of which raise the lactic acid threshold and allow you to
work harder at a higher intensity.
During a really heavy lift, even though the Fast A and Fast B
fibers are activated and doing the bulk of the
work, active Slow
Twitch fibers are producing force and helping lift the weight.
When your buddy stripped off half the weight on the bar, the brain de-recruited the largest and strongest active fast
twitch fibers, leaving the slow and intermediate active and available to continue
working.
If you're going for 3 - 5 RM the slow
twitch fibers wont be of much help, however if you lift in your 25 - 30RM, the slow
twitch fibers will do a lot more
work before the fast
twitch fibers have to kick in.
The fast
twitch fibers were too fatigued to continue
working but the slow and intermediate
fibers were not at the point of exhaustion.
It has been shown that people who have done high volumes of aerobic
work have fast -
twitch fibers that behave like slow -
twitch fibers.
The good news are that there is evidence that upon cessation of doing aerobic
work the fast -
twitch fibers return to their original form.
When you're
working with a weight that's relatively light, to recruit the fast -
twitch fibers, you should again try to be explosive.
More intensity than MAF and the anaerobic engine
works more and more, from now on the body will start to use also type 2 fast
twitch muscle
fibers, use sugar for good, and start accumulating lactic acid.
Therefore, training mostly the capacity to
work at submaximal exercise intensities can improve the oxidation of fats and the performance of the slow -
twitch aerobic muscle
fibers, both of which may be of most importance for endurance success.18
If we keep the argument for single rep training scientific, your heavy
work immediately increases the activation of those important «growth - prone fast -
twitch muscle
fibers».
In addition, slow training only really targets slow
twitch muscle
fibers, which are
fibers that are designed for endurance
work and have no great potential for strength or muscle growth.
We termed this «Capillary Conditioning» to maximize the ability of the capillaries to deliver blood in and out of muscle cells to prepare the athlete to be able to lift more weight, with more repetitions /
work by stimulating development of Type llA Fast
Twitch Muscle
Fiber (Fast Oxidative / Glycolytic or FOG) and less buildup of bulky muscle tissue which is poorly conditioned for aerobic capacity (Type llX Fast Twitch or FG muscle fi
Fiber (Fast Oxidative / Glycolytic or FOG) and less buildup of bulky muscle tissue which is poorly conditioned for aerobic capacity (Type llX Fast
Twitch or FG muscle
fiberfiber).
One solution I found to
work very well for me as far as recruiting both the fast and slow
twitch fibers was a combination of the following sets and reps.
In aerobic activities like sleeping, sitting, standing, walking, jogging and
working at a level that keeps the heart rate below 60 - 70 % of the maximum, only the Slow
Twitch muscle
fibers participate.
To go even further, our fast
twitch fibers can be classified as either Type IIX or Type IIB.11 Fast
twitch fibers show a greater capacity for hypertrophy than slow
twitch fibers, therefore it may be wise to incorporate faster repetition training to maximize this capacity.4 Maximal speed is regarded as a short lasting adaptation, therefore if we wish to keep our bar speed up, we must train with fast bar speed frequently.8 This will have a nice carry over effect to the amount of weight we are able to lift, the amount of
work we are able to perform in a condensed amount of time, and ultimately will increase the efficiency of our training.
The greater the force, the more
work there will be for you fast -
twitch fibers, because our bodies recruit muscle
fibers based on the demands placed upon it.
All of this means that when you challenge your body to do more
WORK — for instance, by going very slowly on the eccentric portion of the movement — you get more of your important type 2 (fast
twitch) muscle
fibers involved... which means you become more metabolically active to burn fat... AND build greater strength.
Now, what they're doing is not really going to
work, because the kind of thing they're doing is similar to what a lot of companies that are offering genetic testing to parents for their kids are doing; they're testing for things like the ACTN3 gene, which is a gene that codes for a protein found only in fast -
twitch muscle
fibers.
