Greetings to everyone. The thought of trying EMS training has crossed my mind many times. I once did advertising for a club, so clients said more positive things. The Chinese are not lagging behind and also offer similar things. Lately, this product has been featured quite often in advertising and discounts. Many people are scared to buy this. but we decided and bought it. Looking ahead, I’ll say right away that I didn’t expect it...
Description from the site
SHANDONG (SHANDONG) Muscle Training Gear - This is a myostimulator to strengthen your muscles. Without even lifting a finger, achieve the body of your dreams. There are two versions (belly pad and shoulder pad), depending on which muscle group you want to get the desired effect. The soft PU pad fits comfortably and gently around the contours of your skin, while electrodes using silk printing and conductive gel sheets effectively distribute impulses.

Operating principle
Now we move on to the complex processes occurring in the body. It is no secret to many that they need irritation to activate muscles. IN everyday life irritation is triggered through the central nervous system, spinal cord, nerve fibers and transmitted to the corresponding muscles. These endogenous stimuli in the physical sense are electrical in nature. The EMS trainer uses the body's inherent effect and enhances external influence our native irritant, thereby causing the muscles to contract stronger and better. In general terms, EMS is the targeted amplification of one's own electrical stimuli from the outside.
Packaging and delivery
We received the goods in 14 days. Delivery throughout Ukraine is now carried out by new mail. I received one item in 8 days. At least some positive aspects began to emerge with delivery. The product is in a thick cardboard box with many inscriptions. It was not damaged and remained intact. You are unlikely to take it as a gift to someone, although if it is for this purpose (maybe to close people). Everything inside is also intact. The packaging is just great. Thick foam rubber with cutouts for components.![](https://i0.wp.com/img.mysku-st.ru/uploads/images/05/13/48/2016/09/10/d1bbf8.jpg)

Equipment
The kit includes multi-page instructions for English, power supply, dual usb-microUSB cable for simultaneous charging of two control washers with brains. There is also a resealable transparent bag for storage and transportation and laminated paper (I don’t know what it’s for). There is also a cutout in the foam rubber for the third control washer, but only two are included in the kit.![](https://i0.wp.com/img.mysku-st.ru/uploads/images/05/13/48/2016/09/10/bbe1ce.jpg)

Characteristics
There is not much information in the store, it only states that there are 6 operating modes and 9 speeds. Looking ahead, I’ll say that speed 2-3 is already “cutting”, then you can only go further large muscles.Here small photo with the parameters from the instructions.
The instructions itself still contain many warnings that it should not be used by patients, pregnant women or those with personal intolerance.
Charging time 20 minutes. The red indicator lights up during charging and turns off when finished.
Photos of instructions
Measurements and dimensions
Management and use
On the main washer (I will call it that) there are three control buttons. The M button is responsible for selecting the stimulation mode, and the + and – buttons are responsible for the intensity (power). As they say in the instructions, you need to go full circle, i.e. six modes to work out the muscle. Choose the intensity based on your feelings. For me, the second regime was immediately shocking. Later, of course, the situation became better, when I began to understand that it was happening at all. There is also a micro USB port for charging on the puck. The puck has a soft touch coating that is pleasant. Everything is done quite well.![](https://i0.wp.com/img.mysku-st.ru/uploads/images/05/13/48/2016/09/10/1abfb3.jpg)

The set includes two butterflies and one ab pad. Butterflies can be placed on almost any muscle, with the exception, of course, of the neck and face (and other intimate parts of the body). The butterflies and the platform are glued to the plates. To use, peel off the protective plate. A hydrogel is applied to the contacts, which will adhere to the skin and improve conductivity. This gel is enough for 30 times of use. Then you can further extend the period by rinsing with water (as indicated in the instructions). Then you need to replace the hydrogel plates. I haven’t found where to buy them yet, but the store has butterflies and a press pad, which are sold without washers. They cost about $14. There are also other options for butterflies. We will look for this gel too. When searching for “conductive gel,” there are many options, but you need one that can be attached, i.e. was sticky.
The device automatically turns off after 20 minutes of use.
Impressions
I immediately tested it on my biceps. I turned on the first mode and the first power position. There was a slight tingling sensation. As soon as I turned on the second power mode, I was simply shocked. I wanted to scream. The arm rose on its own, the biceps tensed and began to twitch in time with the operation of the mode. A minute later the sensations are completely different. You begin to understand how everything works. While working, you can try to straighten or bend your arm, this will not give an even greater effect. If you use it on your legs, you can do a squat in the work mode. The effect is very noticeable. I sometimes go to the gym, I know the sensation of muscle work. Here the effect is, of course, a little different, but the muscles tense in some modes much more than when working with dumbbells or a barbell. Having studied many forums, everyone says that such training works the muscles in more detail and is an additional training from the basis of strength training in the gym. To be honest, after 20 minutes I was still a little tired. The muscles also felt well that they were in action. My abs still hurt. The thing is that you are still trying to resist the work of this stimulant itself, which causes additional load and improves performance.An example of how several modes work. Tested it on the first day. The sensations are ambiguous, but later you get used to it and understand everything.
Conclusion
Overall, I would like to say that the effect exceeded expectations. Honestly, I wouldn't have thought it would be so cool. It’s simply impossible to describe in words, but the muscles begin to work and tense up regardless of you. This device works. If you spend a lot of time in a chair, then your muscles definitely do not receive such loads. You can stretch them in this way, that’s for sure, but if you also do exercises in time with your work, the effect will definitely be better. This is not a panacea for obesity, not a magic thing for abs while lying on the couch, but there is definitely an effect. After 5 minutes you get used to it, you begin to understand how the muscle works. Even Lena didn’t want to, but then she calmly did this kind of training for 20 minutes. There were more smiles and laughter during the test than there had been in a very long time. This was the most fun and interesting unboxing I can remember on at the moment time.
No matter how wonderful everything is, there is one significant drawback - this is a conductive gel, which is a consumable item. If used as intended, out of the box it can last for 1-2 months if you practice daily, but in fact, within two days we got to the point where it began to hold up poorly. I washed it a little with water, dried it and it’s holding up again, but the plates need to be changed soon. I don’t know where to get them yet. We bought it solely for review and did not hope that we would like to use this device. On the first day we just glued one butterfly to different muscles. It was interesting. Thank you all for your attention. Friends, I tried to explain and tell you how I understand it and how it is. Until new reviews.
I'm planning to buy +39 Add to favorites I liked the review +47 +104Very vulgar about myostimulators.
1. The key word is not electrical stimulator, but myostimulator (muscle stimulator)
2. The topic was first thought about and developed by military doctors back in the USSR. Soon after the war.
They worked for the wounded who lay in bed for a long time. Later - for submariners, astronauts - everyone who moves little and loses muscle tone. Even later for athletes to international sports olympiads where achievements are important.
3. With perestroika, all developments went to the west and southeast, where they received a rebirth as consumer goods. By that time, cheap semiconductors had appeared that could generate short pulses without problems. There was a problem with the generation of short pulses - then it could only be radio tubes. Then there were queues for TVs.
There was no need to talk about myostimulants as consumer goods.
4. The idea of electrically stimulating muscles with short pulses turned out to be fruitful.
An impulse or a train of short impulses - 100-500 μs (microseconds), followed rarely - 1-400 times per second leads to a short-term displacement of ions near the nerve endings - myonerons, and this leads to contraction of muscle fibers.
5. The trick is that the average current value in pulse mode is insignificant. This allows you to increase the pulse amplitude to 100 mA, i.e. create an electric field of noticeable volume in the body and force muscles remote from the surface of the body to contract. It should be recalled that a horse is killed by an AVERAGE current of 30 mA (milliamps), and here in a pulse it is up to 180 mA, but the average value is much less.
5a. It is useful to remind everyone who taught and has long forgotten what an electric field is. This is not a field where cows graze. This is the space in which charged particles begin to move.
According to this criterion, all substances found in nature are divided into conductors - they contain charged particles and dielectrics - substances in which there are practically no charges.
In email The field practically does not move anything inside the dielectrics.
A person with his bones, meat, fat and liquids is a conductor. It is saturated with charged particles - ions of sodium, potassium, iron, etc. Under the influence of impulses that create short time email field in the human body, the ions begin to move, but immediately return to their place because The impulses are bipolar and short. This displacement of charged particles is enough to cause muscle fiber contraction.
The MYONEURON reacts - a nerve cell attached to a muscle fiber. It’s as if she receives an impulse from the brain. In fact, its impulse is a reaction to a short-term displacement of charged particles near the myoneuron itself. It’s just the way it is - charges interact with charges. Likely charged things repel, oppositely charged ones attract. This is how the impulse penetrates the myoneuron and causes the muscle fiber to which it is attached to contract.
6. Not everything is in a decrepit body muscle fibers are being reduced. Not every myoneuron associated with a muscle fiber conducts an impulse from the central nervous system. There are many reasons for this.
And then there is a powerful third-party source of a pulsed electric field - all myoneurones that find themselves in the electric field will literally jerk their muscle fibers. The entire muscle will begin to contract, the blood flow will also change, and fat and protein deposits will be pressed away from the moving muscles.
The general feeling is ease in controlling the body as after a workout and no fatigue - lactic acid poisoning.
7. Muscle contractions occur with virtually no release of lactic acid, which poisons the muscles. During normal training, lactic acid must be removed from the muscles. It is muscle poisoning that limits the duration of certain body movements. And here you can shake the muscle faster. In 20 minutes it’s like running 20 km.
It is clear that this can be used to train athletes, which is done while keeping the “training program” in great secrecy before important competitions.
8. Muscle mass noticeably responds to myostimulation with growth. The quality of life increases - in old age you can live in a young body. Unfortunately, the effect of such training lasts 1-2 days. To strengthen it, you either need to move more or regularly connect yourself to a myostimulator. For obese people with excess weight over 10 kg - change the diet and do not wait to lose weight faster than 4 weeks. The fat comes back quickly.
9. There are contraindications, but they are few.
There are no side effects from long-term (years) myostimulation.
Everything, of course, should be taken in moderation, and not to the point of burns at the points of contact with the electrodes.
General recommendations - three days a week for 20 minutes at a level of comfortable muscle tremor - is quite enough.
10. It is important for old people that the muscles of the spine and skeleton can be developed. Get rid of joint pain because... myostimulation naturally eliminates pain from vertebral hernia and pinched nerve fibers almost everywhere where applicators that supply pulsed currents are placed. Also with pain in the hip joints, knee, foot, elbows and neck.
11. The electric field reaches deep, even to the muscles of the stomach, which allows you to change its tone in better side. Plus improved blood flow. The body corrects itself, bringing the necessary components to sick, sick places.
12. A few words about prices.
Actually, the price prompted me to do a search for information.
For 25 years I have suffered from my wife’s character. Her ailments, stomach, head - we share all this together.
This helped her. She dared to pay 95,000 rubles for a Korean device, which, in my opinion as an electronics engineer, is not worth that kind of money. Simple pulse generators, and if there is a processor, i.e. a computer that controls generators according to a program that can be changed - all the same - no more expensive than a mobile phone, and here are these numbers.
It turned out that there really are inexpensive myostimulators from 450 rubles - toys. Make cubes on your stomach. Medium - 1500-3000 rubles - up to 50 programs for different occasions. And there are expensive ones up to 120,000 rubles. professional multi-program and multi-channel. With their help you can heal the entire village. However, the village can be treated with cheaper models for 3-9 thousand rubles.
Expensive models are often focused on cosmetology. Small electrodes. Lots of channels.
It’s worth remembering that there are about 200 muscles on the face. People do not have such a simple interface to communicate with each other through facial expressions. It is important to tighten these muscles, they also become weaker, and the skin becomes thinner.
Remove fat from the face, strengthen muscles, smooth out wrinkles. Ultrasound is used with skin nourishing creams to prolong the effects. It is clear that these models will exploit women's needs for beauty and will be much more expensive.
Keywords for searching - where, what and from whom to buy on the Internet - are on the website www.allmio.ru
The EM41 model (Germans) turned out to be quite good. Powered by 3 AAA batteries. 50 programs.
The size of a pack of cigarettes. Good for hiking - weight 108g - 3 modes (pain relief, muscle training, massage)
In the "pain relief" mode there are subroutines with short pulses that are used for electrosleep. Sleep without sleeping pills is guaranteed. Calm your tired legs and fall asleep - you won’t remember when - the device turns off automatically.
A significant drawback is that Velcro electrodes become old quickly. You need to have spare ones.
Or make it yourself from foil. Glue the foil to thin rubber, and do not remove the Velcro itself to the foil. Lubricate the foil with gel before applying the electrodes to the body.
You will get covered in the gel, but the electrodes will last a long time. There is room for creativity here,
for example, you can create an individual “electric chair” with contact electrodes
For different parts bodies. A suitable gel is sold in a network of medical equipment stores, for example, for ultrasound.
Take a more viscous one.
Expand discussion thread
The human body is capable of self-healing, but sometimes (after injuries, surgeries) this can take quite a long time. For successful and more quick recovery Various are used in medicine. Therefore, we will further analyze what electrical stimulation of the back muscles is, how it is useful and how it is carried out.
The technique is widely used for the rehabilitation of patients after various types of pain, disorders of the functioning of the nervous system, and muscle hypertonicity.
Why is the procedure useful?
The benefits of current stimulation sessions are obvious. So, Using this technology allows you to achieve the following results:
The procedure shows high results in therapy
- Prevention of muscle tissue atrophy.
- Restoration of nutrition processes and elimination of metabolic products.
- Reducing pain of any localization.
- Increased adaptation and muscle fatigue limit.
- Promoting the process of tissue regeneration.
Regular stimulation also ensures recovery " feedback"with the cerebral cortex.
Thanks to this, the nervous regulation of muscle tissue contractions is gradually restored. This is a great achievement in the treatment of severe pathologies (paralysis, paresis).
Devices for the procedure
All devices for electrical muscle stimulation have a main unit in which a current of the required frequency and strength is generated, as well as electrodes attached to the body.
Reference. Each device has different operating modes necessary for a specific muscle group.
Devices are divided into several types according to their purpose:
- professional- used in medicine and cosmetology;
- low-power- intended for use at home.
Devices are also distinguished based on the nature of the outgoing currents:
- "Amplipulse-4.5", "Stimul-1"- for recovery and stimulation of muscles using sinusoidal currents of high frequencies, modulated by low frequencies.
- "Neuropulse", "UEI-1"- used for reduced electrical excitability of muscles. Currents flow in rectified mode.
Various devices have been developed for stimulating muscles with current.
There are many other devices in medicine, each of which has its own application features: “NET”, “Tonus-1”, “Myovolna”, etc.
Electrical stimulation at home
The technique is quite simple to perform, so you can perform electrical muscle stimulation at home.
The session flow includes several stages and looks like this:
Can be used at home
- electrodes are moistened with water and placed on the affected muscle tissue and secured with bandages;
- wires are connected;
- a suitable program is launched on the device;
- The current strength increases in stages, 3-4 minutes after the start of the electric shock, until the moment when the current is no longer felt. muscle contractions;
- after the end of the session, the device is turned off and the electrodes are removed;
- The skin in the area where the electrodes are applied is treated with a tonic to moisturize.
It is imperative to study the instructions for the electrical muscle stimulator, which will ensure the correctness of the procedure and the effectiveness of the treatment. If the technique of performing sessions is not followed, side effects may develop.
How often can the procedures be done?
How often can you do electrical muscle stimulation?? Treatment with a similar physiotherapeutic method is carried out 2-3 times a week, however, it is possible to conduct a session every other day (depending on the indications).
Reference. The therapeutic course includes 10-20 sessions.
The duration of the procedure should be approximately 20-40 minutes. A repeat course can be taken no earlier than 1 month after the previous one.
Side effects
There are practically no side effects
There are practically no side effects of electrical muscle stimulation.
The only thing that can be noted is a feeling of muscle discomfort during the session and after it.
Also, an inflammatory reaction may occur at the points of contact between the skin and the electrodes.
In order to avoid such undesirable reactions from the body, the patient must monitor his well-being during sessions. If discomfort occurs, even minor, the patient should inform the doctor.
The list of contraindications to electrical muscle stimulators is extensive. When prescribing therapy, it must be taken into account by the doctor.
Important! The procedure may accelerate the progression of some diseases, leading to undesirable consequences.
It is prohibited to carry out the procedure in the presence of the following circumstances and diseases:
Has a large list of contraindications
- oncology;
- infectious diseases;
- arterial hypertension;
- epilepsy;
- hyperthyroidism;
- blood pathologies;
- heart failure above degree 2;
- active form of rheumatism
- presence of pacemakers;
- formations of a benign nature;
- atrial fibrillation;
- phlebitis, thrombophlebitis;
- violations of the integrity of the skin (abrasions, wounds, cuts);
- condition after suturing muscles, tendons, nerves (for 1 month).
This method of treatment should not be used in pregnant women., since the procedures can cause an increase in uterine tone, which can result in miscarriage or premature birth (depending on the stage of pregnancy).
Conclusion
Therapy of pathologies of the nervous and muscular system cannot be imagined without physiotherapeutic techniques. Among the variety of procedures, electrical stimulation is the most active and shows high results in treatment.
Description of the method
Electrical muscle stimulation is an internationally recognized clinical method of physiotherapy in specialties such as orthopedic and neurological rehabilitation. When applied to a central or peripheral partially damaged nerve, electrical stimulation can induce a muscle response in patients with limited or lost muscle activity. This method is a complement to physical therapy and should be combined with active training, strength and coordination exercises. The method is simple and suitable for treatment both in a hospital and on an outpatient basis at home.
Operating principle
NMES stimulates the motor nerves to generate muscle contractions, as opposed to low frequency TENS which creates small muscle twitches. NMES also stimulates A-beta nerve fibers (as does TENS), which has an analgesic effect.
Examples of indications
- restoration of quadriceps function after surgery
- maintaining or increasing the range of active movements
- capillarization
- reduction of muscle atrophy/hypotrophy
- maintaining muscle strength during the period of immobilization
- prevention of loss of muscle strength after surgery, for example on vastus medialis
- reduction of spasticity, such as reciprocal inhibition of the flexor muscles of the arms in patients with hemiplegia
- training after partial peripheral nerve injury with reinnervation symptoms such as plexus injury
- peroneal muscle stimulation
- incontinence treatment
- anesthesia
- warm-up
- increased muscle strength
- recovery
Treatment by NMES method
Installation of electrodes
To achieve good results Correct placement of the electrodes is extremely important. The muscle contracts due to stimulation of the motor nerve. The motor point is the area on the skin that is closest to the point where the motor nerve enters the muscle. This is the most advantageous place to induce contraction using electrical impulses. The NMES programs of Cefar stimulators generate a symmetrical biphasic wave, that is, the polarity is constantly changing. This means that both electrodes are equally active.
There are different methods for positioning the electrodes. The most optimal way is to install a pair of electrodes above the elevated area of a given muscle. By installing one electrode over the motor point of the muscle, you will get the strongest possible muscle contraction without discomfort. When installing electrodes over motor points different muscles You can effectively work large muscle groups.
What size electrodes should I choose?
A larger muscle group requires a larger electrode area. For a small muscle group, small electrodes are better suited, as they are more specific, which provides a higher current density (mA/cm2). Large muscle groups may also require dual-channel stimulation, which uses four electrodes simultaneously.
What pulse frequency and duration should I choose?
NMES typically operates at frequencies of 20-120 Hz. To increase blood circulation, choose frequencies up to 10 Hz. The goal is to induce vibrations, not contractions. Adjust the pulse duration relative to the amount of energy in each pulse. When stimulating a small muscle group, a short pulse (say 200 µs) is usually sufficient, while a long pulse (eg 400 µs) is used for a large muscle group.
NMES 20-70 Hz
1.Lift
2.Stimulation period
3.Recession
4.Pause
The illustration above demonstrates electrical stimulation of a muscle. Begins with a lifting phase (1), during which the contraction gradually increases, reaching a maximum contraction in the stimulation phase (2). In the decline phase (3), stimulation gradually weakens and enters a rest phase, in which stimulation stops or is at a moderate level (active rest). Active leisure prevents muscle injury and prepares the muscle for the next contraction. Stimulation with regular pauses is called intermittent.
What sensations should stimulation cause?
The purpose of NMES is to induce muscle contractions. Increase the amplitude above the somatosensory barrier until you see a motor response. The patient often experiences an electrical contraction greater than a voluntary contraction. But contractions should not cause discomfort.
Testing the electrode installation position.
The motor point finding electrode and gel help determine the optimal location for electrode application. By sliding the movable electrode over the surface of the skin, you find the position with the maximum and most comfortable muscle contraction. Often the patient needs to get used to the stimulation, and the first sessions may not reach therapeutic intensity. During the course of treatment, the intensity of stimulation should gradually increase. At the first session, a short session may be conducted to determine the patient's response. Excessively strong muscle contractions caused by electrical stimulation can injure a muscle that is not prepared for the load. A gradual increase in load and regularity of exercises ensure a good treatment result.
To achieve good results, NMES can be combined with other types muscle training. Muscle stimulation can act both in the phase of concentric and eccentric movement, or only in one of them. It depends on how you combine stimulation with voluntary movements.
What should be the duration of treatment?
Depending on the condition of the muscles and the patient's rehabilitation phase, treatment can last from 5 to 60 minutes and be repeated from three times a week to twice a day. To intensify the treatment, you can gradually increase the duration of stimulation depending on the pause. You can also increase the amplitude, frequency and/or duration of the pulse.
Denervated muscles.
Stimulation of denervated muscles differs from stimulation of muscles with preserved innervation.
If the innervation of the muscle is preserved, you can stimulate through the motor nerve, but if the muscle is denervated, you must stimulate the muscle fibers directly to induce contraction. The goal of stimulating denervated muscles is to maintain their contractile units while awaiting possible reinnervation. To generate a contraction, the pulse duration is 100-300 ms. Rectangular pulses are used for completely denervated muscles, while triangular or trapezoidal pulses are used for partially denervated muscles. This helps to separate fibers with preserved innervation and denervated ones.
Switch.
To adjust the duration of the pause and stimulation periods, you can use the switch during electrical stimulation. The switch is especially practical when electrical muscle contractions are combined with voluntary contractions. The result is effective individual treatment.
Installation of electrodes.

EMS training (Electrical Muscle Stimulation) is the impact on muscles of a device or simulator that sends weak electrical signals through electrodes attached to the surface of the skin. In essence, the device for electrical muscle stimulation generates impulses similar to real muscle contractions during strength exercises.
Advertising of exercise machines and reviews of EMS training studios promises to create strong muscles and a fit athletic body in just 20 minutes of training three times a week, and home EMS abdominal belts “guarantee” sculpted abs without grueling crunches. You just need to put on this electric belt while watching TV, while no exercise is required.
Unfortunately, the evidence base for EMS training is highly controversial. Even if the myostimulation method can increase muscle tone, in most cases, training advertisements significantly overestimate the advantages (especially for weight loss and the fight against cellulite) - and never talk about the disadvantages, possible harm and contraindications. In turn, home EMS abdominal exercise machines are more likely just a toy.
Who invented EMS?
The history of muscle stimulants dates back to the 18th century, when researchers discovered that weak electric current can provoke contractions of a certain muscle in the human body. In the 1960s, Soviet scientists announced that they had developed innovative training mechanics for professional athletes that could increase their muscle strength by a significant 40% (1) .
Later it turned out that it was more about special restorative and rehabilitation therapy, and not at all about a technique for increasing strength and muscle mass at healthy athletes. Then, in the 1970s, Germany began to use electrical muscle stimulation in physical therapy and accelerated recovery of athletes. The first EMS training studios also appeared in Germany - Bodytec and Miha.
EMS trainer - customer reviews
As for reviews of the direct operation of such equipment and the sensations during EMS training, most people note noticeable effects. Pulse currents as if they are squeezing the body from all sides, forcing the muscles to contract. It is quite difficult to resist them, so even simple physical exercise become a test. During training, your heart rate increases and your breathing may become difficult.
Note that the cost of a professional EMS simulator can be hundreds of thousands of rubles - this pushes sellers to “black” Internet marketing techniques, which involve publishing fake reviews. In no other Fitseven material do we see such a high level of activity from “happy customers”, detailing how happy they are with their pumped-up muscles and slimmed-down body.
How EMS training works
Typically, one full workout in an EMS studio lasts about 20-30 minutes. The person puts on a special suit with electrodes, and the trainer regulates the power of electrical impulses for each part of the body, based on the sensations and endurance of the trainee. Then simple physical exercises are performed for various parts of the body - squats, bending and straightening the arms, swinging to the sides, and so on.
The final stage of the training is lymphatic drainage massage, during which you only need to lie down and enjoy the pleasant tingling sensations.
Trainings are held 2-3 times a week.
Real reviews about EMS
As a physiotherapist, I have repeatedly encountered complications from pulsed currents in women of all ages and young girls - life-threatening bleeding from the uterus (rupture of the corpus luteum) occurred. It has now been convincingly proven that, even in the absence of contraindications, ladies and girls should not undergo this kind of procedure.
After the 4th workout, fluid formed above the kneecap, and by the evening the knee was completely swollen. I went to the emergency room and the doctor said that due to the heavy load on the body, he generally forbade such training, everyone’s body is different and it is not known how it will react to such training.
Firstly, electrical stimulation on a constant basis is harmful to the heart; secondly, external stimulation is not a neural impulse, the muscle works without connection with the brain, where is the development of movement stereotypes?; thirdly, these studios hire just anyone to become trainers (look at the ads on headhunters); fourthly, this trend is for the lazy and those who supposedly don’t have time for full training and the desire to break with one’s own body.
EMS training- pros and cons
The first commercial EMS personal training devices appeared in the United States in the late 1990s. Manufacturers tried to give their products and the abdominal muscle stimulation method as much credibility as possible by organizing all sorts of scientific congresses and developing intricate certification methods for the equipment they themselves produced - but without real scientific support.
One attempt at such certification used the wording "weight loss and weight loss device" - but was categorically rejected by regulators as misleading. EMS was eventually certified as a treatment for muscle wasting and spasms in bedridden patients, but not as a technique for muscle growth or body contouring (2) .
EMS ab belt - does it work?
A separate area of EMS technology is home exercise equipment and belts for creating relief press. Intrusive advertising and numerous reviews of “happy customers” promise fat burning, instant definition of cubes, getting rid of cellulite and others positive effects. All you have to do is buy this belt and watch TV in it - and your belly will go away on its own.
Unfortunately, most households EMS belts for the press are only a low-quality toy from a nameless manufacturer. Even with careful use, they fail literally within the second week. We also note that such a belt must be “glued” to the skin using replaceable gel pads or even paper tape - which means that the stomach will have to be shaved.
EMS: contraindications and harm
We also note that the EMS training method has a serious list of contraindications - from pregnancy to the presence of a number of chronic diseases - including any circulatory disorders, diseases gastrointestinal tract, kidney failure, cancer and so on. Among other things, there are risks if you have a common cold.
IN separate group Contraindications for electrical stimulation include people with pacemakers and other correction devices heart rate as well as persons who have suffered bone fractures, sprains or any damage to the skin in the recent past. However, when selling a subscription in EMS studio trainings often “forget” to warn about this.
Final opinion
Even though EMS training may be effective for bedridden and paralyzed patients, they are not able to influence muscle growth, weight loss and noticeable fat burning, or get rid of stretch marks, cellulite or any other improvement in body contours. In addition, the EMS method has a significant list of contraindications and is not recommended even for a serious cold.
Manufacturers of EMS simulators have been repeatedly fined for false advertising and misleading promises that the myostimulation technique can replace strength training and create “an iron press completely without effort and without a drop of sweat” (3). Moreover, most of the rave reviews on the Internet are most likely fakes, written at the request of the manufacturers.
***
EMS training increases muscle tone exclusively in untrained people and in paralyzed patients, without affecting either fat burning or getting rid of cellulite. It is also important that manufacturers of such equipment have been repeatedly fined for misleading advertising that EMS simulators able to “create muscle without effort.”
