What is EMS myoelectric stimulation to help you have a good figure
September 12, 2021

Most people may be shocked when they hear the word EMG, and it is easy to think of the mice under Frankenstein, or the crazy neurologist. But in fact, the use of EMG in the medical and health field is beyond imagination. Common ones include pacemakers, electrocardiographs, acupoint stimulation, beauty treatmentshttps://www.lefislaser.com/category/ems/, and more. Now, myoelectric stimulation technology has been extended to the field of daily sports, and it is expected to become a new way of exercise.

So what is EMS myoelectric stimulation? So what’s so special about it?

EMS, the full name of Electric Muscle Stimulation, that is, muscle electrical stimulation technology.

We all know that the general movement pattern of the human body is issued by the brain, which is transmitted to the terminal muscles in the form of nerve impulses, causing the muscles to act. The EMS technology is different. The device sends out a current pulse signal, which directly acts on the human muscles without going through the brain, so that the muscles “move by themselves”.

So, what is the practical use of this technique of making muscles move on their own, apart from looking amazing? This starts with the composition of human muscles. Human muscles are actually made up of several different “subtypes,” the two most important of which are called fast twitch and slow twitch. These two types of muscle fibers differ in many ways, including muscle contraction speed, contraction force, and endurance levels. Fast twitch muscles have fast contractions and great strength, but are prone to fatigue and tend to support anaerobic exercise; slow twitch muscles have slow contractions and low strength, but are less prone to fatigue and support aerobic exercise more. Although all muscle fibers have the potential to grow, the degree of enlargement varies, and large muscles are built primarily due to the growth of fast-twitch fibers. But traditionally, building fast twitch

It takes a lot of high-intensity training, long-term adherence, and a lot of protein supplementation to achieve results. Therefore, the scientific community has been constantly exploring and breaking through the traditional way of exercise, and electromyography is one of the most in-depth development.

As early as 1791, Italian doctor Luigi Galvani proposed the theoretical basis for the relationship between muscles and electrical signal stimulation, and between the 19th and 20th centuries, researchers found that long-term electrical stimulation would have an impact on long-term changes in muscles, and in the 20th century. It was used in the training of elite athletes in the 1960s and claimed up to a 40% gain in muscle strength. People call this program Electrical Muscle Stimulation, which is EMS electrical muscle stimulation technology.


Initially this technique was used for the rehabilitation of persons with limited motor function. Knee injuries such as chondromalacia. This type of injury is caused by impaired voluntary control due to reflex impairment and pain. Myoelectric stimulation can play a role in preventing muscle atrophy and functional degradation.

Later, this technique began to be applied to the sports training of athletes. Because studies have found that high-frequency, short-term EMG stimulation can significantly increase the strength of well-trained athletes. A friend of the well-known superstar Bruce Lee revealed in an interview that he used to use electric shock stimulation to keep his muscles strong. It’s just that the electric shock method he used was too much in terms of current and frequency, which caused certain damage to the body.

With the continuous development of EMS technology, Professor Toshio Moriya from Kyoto University, after nearly 30 years of research, proposed the most suitable EMS theory for active muscles. 20Hz was found to be the most suitable frequency of electrical pulses for triggering muscle movement. In the actual test, the consumption of muscle tension over time at this frequency is much smaller than that of other frequencies, that is, the muscles can maintain a relatively high energy consumption state for a longer period of time. Therefore, there are two more favorable conditions for the promotion of EMS technology to daily household life. First, the determination of the optimal frequency of 20Hz greatly simplifies the operation process and hardware requirements of the EMS. Secondly, 20Hz stimulates muscle growth while causing less pain, making it easier for users to accept this exercise method.

Of course, EMS technology can be more perfect when paired with the right daily exercise, and using these devices alone may not allow you to develop six-pack abs in a very short period of time. In the existing data studies, repeated stimulation of the muscle can make the muscle stronger within a certain range, but it is likely to return to its original state if it cannot be sustained. Be sure to remember that persistence is an essential key element of a perfect body, whether using EMS equipment or self-exercising.

Combine the low-frequency current that stimulates the superficial muscles with the intermediate-frequency current that stimulates the deep muscles, so that the muscles can be exercised as a whole. At the same time, the rollers are used to knead the muscles and perform myoelectric stimulation to improve muscle quality, effectively tighten muscle lines, and massage acupoints. . The double-roller design used imitates the massage techniques of “push”, “pinch”, “knead”, and “release” of beauticians in beauty salons to dredge lymph, lose weight and detoxify, allowing you to easily sit on the vest line.
