What Is EMS Technology?

EMS stands for “Electrical Muscle Stimulation.” It involves the use of electrical impulses to cause muscle contractions, leading to muscle growth and strength. The technology has been used in the rehab, fitness and sports industries to enhance performance and promote rehabilitation.

With this form of muscle stimulation, current impulses are passed through electrodes attached to the skin or to special functional clothing to the muscles to be trained, which leads to an involuntary contraction of the muscles located under the electrodes. Especially in strength training, EMS causes an increase in the voluntary contraction, which can be done isometrically, in a certain angular position or dynamically over a certain range of motion. In practice, the EMS user tenses the muscles isometrically or performs dynamic movements. This leads to an intensification of the physiological muscle stimulus through the applied electrical stimulus. In addition, if used correctly and efficiently, there is the possibility of combined training, in which a mechanical stimulus (e.g. through dumbbell training or other additional materials) and EMS are used simultaneously. With regard to this possible combination, the consideration of the exact usage requirement should be clarified again. There are theoretical and practical differences in the implementation of a classic 1:1 personal training compared to e.g. B. conducting personal training within a micro-studio or a gym that specializes in this form of training. The adjustment is made to the needs of the customer and must be aligned with his needs and goals accordingly.

The roots of EMS lie in the therapeutic area. In patients who are immobile due to injuries or operations, the muscles can be isometrically contracted using EMS, thus preventing muscle atrophy. EMS is also commonly used to treat osteoporosis prophylaxis and back pain. 

Biophysics Behind EMS

  • Human Body fluids are electrolytes = conductors
  • Most organs are ordered by electrical impulses
  • Skeletal muscles also receive the impulse from CNS
  • The Electric Pulses can be prepared artificially and delivered into the body by special equipment such as VBTec

VBTec PDT is a total body workout with body current. In this context, it might be helpful to know that our muscles contract through electric impulses (bioelectronics) in normal state. VBTec PDT makes use of this effect with electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, which is the elicitation of muscle contraction using electric impulses. The impulses generated by VBTec PDT are delivered through 20 pre-placed electrodes in the
VBTec Power Suit that make contact with the skin near the muscles stimulated.

VBTec PDT utilizes both low and middle Frequencies (0hz-7000hz) which stimulates Type I & Type II muscle fibers activating 90% of these muscle fibers in the body. Low frequency (EMS) is traditional EMS and offers surface stimulation. This requires the body to feel the current and send a message to the brain and wait for the brain to send a message back to inform the muscles to contract based on the perceived stimuli. Middle frequency (EMA) provides a stimulus directly to the muscle fibers by penetrating deeper than a low frequency stimulation thereby immediately contracting the muscle fibers. The neuropathic message is sent to the brain that the muscle is already in a state of contraction. This type of involuntary contraction and the change in the neural pathway reverses the voluntary exchange between the brain and the muscle which thereby assists with neuroplasticity.

An Ancient Science

The application of electrical stimuli to the body has existed in various forms for several hundred years. Sources of electricity for certain animals are said to have been found for the first time as early as 200 BC. in Asia Minor (Vatter, Authenrieth & Müller, 2016). The Roman physician Scribonius Largus (AD 14-54) used animals as a source of electricity to treat pain. In his collection of recipes “Compositiones Medicae” he reports on the treatment of head neuralgia/gout and pain using electrical impulses from electric eels, electric rays or electric catfish. These animals deliver bursts of voltage ranging from 300-800 volts and were placed either on the patient’s head or under their feet or in a pool during treatment. The exact mode of action and physiological background were largely unknown at the time.

EMS : The Past Til Now

On the above-mentioned basis (animals with electricity), the mayor of Magdeburg, Otto von Guericke (1602-1689), developed the first friction electrification machine. A rotating sulfur ball was used as a friction body, which, after being charged by friction with a cloth, either attracted or repelled paper or feathers. 

The doctor Christian Gottlieb Katzenstein first used these electrifying machines for medical therapy. In 1745 he wrote the book “Treatises on the Use of Electricity in Pharmacy”. A therapeutic application of the friction electrification machines was named after Benjamin Franklin (1706-1795) known as Franklinization. Here, a pain relief occurred through targeted short electric shocks to certain parts of the body.

In 1745, at the same time as Dean Kleist, Professor Pieter van Muschenbroek discovered a way of briefly storing the electricity generated by the electrification machines using the Leyden bottle (also known as Kleist’s bottle). Inside, two electrically conductive plates face each other, which in principle is similar to today’s capacitors. Due to their high withstand voltage, they are mainly used as high-voltage capacitors. 

Italian physician named Luigi Galvani in the late 1700s  discovered that electrical currents could cause muscle contractions in frog legs.

Over the years, the application of electrical stimulation to muscles for medical purposes continued to evolve. Researchers began to explore the use of electrical stimulation for therapeutic and rehabilitative purposes. This included the use of EMS to help patients with muscular atrophy and other neuromuscular disorders.

And EMS has been used as a specific form of training in competitive sports since the late 1960s as well. In this setting, however, the focus is primarily on strength and muscle mass gains. In the 1960s, EMS technology was also used in the USA and the former USSR in space travel to maintain muscle mass in weightlessness and in the military to improve soldier performance. In the 1970s USSR won the most medals during the Olympic games thanks to the EMS technology. The Olympic anti-doping committee was about to ban EMS technology as a stimulating drug. But as a natural way to increase your strength and endurance ,with 20-25% can’t be banned as our brain does this naturally.

In recent years, however, EMS technology has found its way into the fitness/wellness sector. From the original local EMS application, a new technology was developed – whole-body EMS training (WB-EMS), in which electrode vests and electrode belts or -cuffs several muscle groups of the body can be stimulated simultaneously in the sense of a full body workout. Due to the proven effectiveness and time efficiency (high training effect with low time investment at the same time), WB-EMS training is enjoying increasing popularity in the fitness and wellness industry.

The interest in EMS training is rapidly growing. The technology has become more advanced, with new wireless and portable devices making it easier for people to train. Additionally, studies have shown that EMS can be effective in promoting muscle strength, endurance, and recovery, leading to increased popularity in the fitness industry.

Today, EMS training is a popular form of exercise and rehabilitation, used by professional athletes, fitness enthusiasts, and people seeking to improve their overall health and wellness.

Backed by Science

None of the benefits of EMS/EMA technology mean anything if they don’t truly work. That’s why we’ve compiled a collection of studies that have proven that the benefits of EMS/EMA technology are natural and effective. These studies have provided valuable insight into the effects of EMS/EMA on the body for various uses. All of the innovation we’ve been able to achieve has been possible because of the scientific discoveries made in the world of EMS/EMA technology. 

The discoveries that tell us what, why, and how not only answer existing questions, but push us to then ask what’s next. If we can already do so much, what will the next study tell us, and how can we use it to advance further?
