How to use a TENS units & EMS machines to build muscle & muscle atrophy? Placement of electrode pads

In the second decade of the 21st century, muscularity and fitness gained tremendous importance; having a sculpted body is synonymous with beauty, success, discipline and above all confidence. However, today's working lifestyle does not leave much time to devote to this task, so many people find themselves at a serious crossroads.

Fortunately, electrotherapy can help to solve this problem. Thanks to EMS currents, you can sculpt and tone your muscles from basically anywhere, and all you need is a power outlet to plug in your muscle stimulation machine. If you want to know how to take advantage of this technology, read on to the end.

How to use EMS machine to achieve muscle hypertrophy?

As you have realized, it is perfectly possible to achieve muscle hypertrophy using an EMS electrostimulation machine. That's why below we are going to teach you the key aspects of this therapy that you should know.

Benefits

On its own, muscle electrostimulation is beneficial, but by using it to achieve muscle hypertrophy you can take full advantage of these benefits. Among the most important we can highlight:

  • Fatigue resistance: muscle electrostimulation reduces the oxygen consumption of the muscles, which translates into greater resistance to fatigue, allowing you to train at the highest level for longer.
  • Improves power: by reducing muscle fatigue, you achieve greater speed in the recruitment and activation of muscle fibers, which translates into greater muscle power as they will respond more quickly to the contraction stimulus.
  • You save time: by training with an EMS electro stimulator you can keep in shape from the office or while doing household chores, which saves you a lot of time going to the gym.
  • Resistance to injuries: by having muscles that are less fatigued and more powerful, you can be more relaxed as the incidence of muscle injuries will be considerably reduced.

What intensity to use?

For muscle hypertrophy, a frequency between 50 Hz and 100 Hz should be used. The exact number will depend on the size of the muscle to be trained, since the smaller the volume of the muscle, the less intensity it will resist. Therefore, when training small muscles such as biceps, triceps, deltoids or calves, a frequency of 50 Hz to 65 Hz should be used.

For larger muscle groups such as the back or legs, an intensity higher than 65 Hz can be used. However, it has been proven that EMS will be most effective when working locally, that is, when working each muscle individually rather than a broad muscle group.

More types of EMS electrostimulators and TENS units you should know

Can you gain muscle mass with electrotherapy?

Electrotherapy can help you gain muscle mass and tone your muscles. To do this you must first understand how the muscle building process works, as this is key to understanding how muscle electrostimulation can help you in this task.

Muscles are made up of fibers. When we train intensely and heavily in the gym, and we push a muscle to failure or close to it, which is nothing more than exhausting it as much as possible. These fibers weaken and become inflamed, breaking down at a microscopic level. This damage is known as hypertrophy, and forces the body to generate new muscle fibers over the old ones, which gradually generates an increase in muscle mass.

Of course, it is not enough just to generate hypertrophy to gain muscle, since nothing can be achieved on a biological level without first giving something in return. In this case, in order for the body to have enough energy to generate new muscle fibers, it will be necessary to have a good hormonal balance, and to consume enough proteins or amino acids, which are essentially the raw material used by the body to build muscle.

While electrotherapy cannot do the latter, and you will be forced to change or improve your eating habits to achieve results that will last over time, it can help you generate muscle hypertrophy. For this there is its EMS modality, which specializes in muscle stimulation, being able to generate enough stress in them to achieve the desired increase in their volume.

TENS vs EMS: Which is better for building muscle?

Currently, there are two electrotherapy modalities that have gained popularity over the others. The first of these is muscle electrostimulation or EMS. What this does is to use high frequency currents to stimulate a muscle and generate a contraction, thus imitating the contractions you get when doing a press at the gym or lifting a dumbbell.

Depending on the frequency used, enough tension and stress can be generated in the muscle to achieve hypertrophy without the need to lift 1 kilogram of weight. This occurs because the current maintains the muscle contraction for a few seconds, which is enough to, with each contraction, stress the muscle fibers and thus generate the necessary damage to stimulate muscle building.

On the other hand, TENS or transcutaneous electrostimulation works in a different way. It uses lower frequency currents, which do not influence the muscle tissue, but only the nerves. The main purpose of this technique is to relieve pain, since the currents act on the nerve receptors to increase their tolerance to pain.

Knowing this, it is clear that for muscle building and toning, the most effective therapy is EMS, since it is designed precisely for this task. TENS can be a valid option for recovery processes, but its functions do not affect in any way the construction of new muscle fibers.

Contraindications in the use of electrodes pads and electrotherapy

Contraindications for electrode placement

The placement of the electrodes is of utmost importance in electrotherapy, whether TENS or EMS, so here are some things to keep in mind before starting a session:

  • Symmetrical placement: the negative and positive poles of each electrode should be connected symmetrically. That is to say, if we use two pads, we should use one positive and one negative pole on each one, while if we use four, the equivalence should be two positive and two negative.
  • Do not cross the electrodes: you cannot use one electrode in the lower train and another in the upper train and more importantly, never cross the electrodes from the left side to the right side of the body and vice versa, since the current path can negatively affect the patient's health. For this reason it is always recommended to use the electrodes in a localized way.
  • Motor point: at least one of the electrodes, whether positive or negative, must be positioned over the motor point, which is the point where the greatest force is achieved in the muscle in question.
  • Control the intensity: the size of the muscle must be taken into account when choosing the intensity of the current, since the less volume and size the muscle has, the lower the tolerated intensity will be.
  • Be careful with the skin: EMS or TENS should not be used on recently depilated areas since the pores will be open and this could generate skin sensitivity. Do not use on irritated or reddened areas, open wounds or recent scars.

Contraindications for the use of electrostimulation

Being a therapy that applies currents to the body, it cannot be used for all conditions, therefore its use should be avoided in cases where the user suffers from the following conditions:

  • Epilepsy.
  • Cardiac pacemakers.
  • Circulation disorders and problems.
  • Abdominal or inguinal hernias.
  • Neurological disturbances.
  • Tendency to bleed.
  • Skin irritation, burns or wounds.
  • Diseases that affect muscle metabolism, such as diabetes.
  • Metabolic syndrome (diabetes, hypertension and obesity).
  • High uric acid levels.
  • Metabolic disorders and metabolic pathologies.
  • Inflammatory pathologies.
