Types of frequency and muscular electrostimulation effects:
We know approximately the results that we can obtained from a standard sport training , if we dedicate ourselves to run in popular races, we know that there is a general period in which we will carry out a greater work load, focus in a more pure aerobic resistance, in a specific period we will dedicate some more time to the force work if we want to improve our mark in the race, this as a simple summary, happens exactly the same when we want to make a physical preparation adapted to any sport or competition with the electrostimulation, this does not entail any difficulty when we understand that we have to work with a range of frequencies that allowed us to generate the precise stimulus to obtained a muscular work with the amount and the desired efficiency.
Like the continuous race, the series or the farlek (a training method), that involve a change in the frequency and in the common way of training through a electro stimulator we can also use different frequency ranges that at the same time will produce a different effect, as we can see our body adapt physiologically both to a electrostimulation training like a common training whether these are strength, endurance or velocity, or a combination of the factors previously mentioned, the similarity in between one type of training and other is maximum as the electroestimulator equipment we use meets the best quality conditions and gets close to a optimist physiological for each type of training.
The type of frequency selected is the key to indicate to our body wich type of fiber to activate essentially, to say it in another way, to put it in another way, the chosen frequently mode will be able to stimulate the type of muscle fiber that we want at that time, that suits us more for the training phase where we are, like we previously remarked in a rough way, a high frequency with adequate breath will allowed us to developed a strength a anaerobic resistance, low frequencies will allowed our muscles to relax and get better in our aerobic resistance. We are going to be more specific in relation to the frequency effects and expose an approximate summary:
1- In between 2 and 4 Hz we will obtained a relaxing effect of the muscle or a group of muscles we are working on, even if we have overloaded the area and to appear pain we will be able to observe how in many occasions it gives away importantly or disappears all together, we are not producing a anesthetic effect over the area, but we are improving the throphism favoring the circulation, dragging waste substances and also with a frequency of 4hz, we are at threshold where encephalins are generated that will raise our pain threshold and therefore this one stops bothering us.
2- In between 4 and 8 hz we obtain a remarkable elevation of the segregation of endorphins at the same time we increased the intensity until we noticed clearly the contraction and we have correctly placed the electrodes we will get a massage effect on the muscle group we are working on which in addition to raising the threshold of pain we wil have positive effects that happen to a local massage such us: intense relaxing effect on the area, improves local circulation, decrease of toxic metabolics, improve oxygenation.
3- In between 8 and 12 HZ we will achieve a big increase of the local circulation, with all that this supposes: Elevation of trophism, decrease of metabolites, oxygenation of tissues and a certain massage effect adjusting the parameters so that the sensation is pleasant.
4- Between 12 and 40 HZ we will put into action essentially slow fibers, to give an example would be a muscular work of smooth continuous race by means of which we will improve our aerobic capacity doing a work without hardly oxygen deficiency.
5- Between 40 and 60 Hz according to the amplitude we will recruit more intermediate fibers and even fast, with this training we will be achieving a higher level of load than with the previous one, greater muscular resistance and we would enter into force work, improving at the same time Our level of oxygenation.
6- Between 60 and 80 HZ according to the amplitude will be incorporated into muscle work fast and intermediate muscle fibers, we are already fully engaged in the work of strength and development of the muscles.
7- Between 80 and 120 Hz will work with high intensity fast fibers and with this work we will improve the strength, speed, the combination of both: muscle power and all without a feeling of physical or psychological exhaustion.
