What is behind the "vomit" currents generated in the LIPOSANA3?
Of course, we are often asked what significance the so-called vomiting currents have in LIPOSANA3. This type of stimulation is often referred to as Russian stimulation. In recent years, electrical stimulation of the muscles has become an important tool in the rehabilitation of muscles after injuries or operations. One of the methods of electrical stimulation is the so-called "Russian electrical stimulation ", also known as "Kotz currents". Russian electrical stimulation uses a specific type of electrical stimulation, the square wave, and modulates it with specific frequencies to stimulate the muscles. These represent part of the frequency spectrum generated in the LIPOSANA3 and LIPOSANA3+.
The "Russian electrostimulation" with Kotz currents was developed in the 1980s by the German physiotherapist Dr. Y. Kotz. It is believed that he developed the method to improve the rehabilitation of athletes and maximize the effects of sports training. Dr. Kotz experimented with various forms of electrical stimulation and found that the use of square waves at certain frequencies was particularly effective in increasing muscle strength and mass as well as relieving pain. Since then, the method has been used by physiotherapists, sports trainers and athletes worldwide. The most important finding is that modulating medium-frequency currents to low-frequency currents is helpful for the above-mentioned areas of treatment. We have written a separate article on the subject of modulation:
What is the significance of modulation for LIPOSANA3 and LIPOSANA3+?
Square wave - Kotz current
The square wave is a form of electrical stimulation generated by a specific type of signal that alternates between two voltage values at regular intervals. The square wave has a fast rise and fall time and therefore produces fast and intense contractions in the muscles. This fast contraction is ideal for stimulating the fast muscle fibers needed for activities such as running and jumping.
Kotz currents use the square wave to generate a high number of contractions per second. This high frequency leads to intensive stimulation of the muscles and can lead to an improvement in muscle strength and mass.
Which frequencies are used for this?
Russian electrostimulation uses specific frequencies to stimulate the muscles. The frequencies are generated by modulating the square wave by modulating the frequency of the square wave by a higher frequency. The Kotz currents are normally modulated at a frequency of 1 kHz and can be combined with various lower frequencies.
Here are the most important frequencies used for Kotz currents:
1 kHz modulated at 33/66/133/200 Hz
The Kotz currents at 1 kHz modulated at 33/66/133/200 Hz are ideal for stimulating the muscles to build strength and mass. The lower frequencies (33-66 Hz) produce deep muscle contractions and are therefore ideal for stimulating slow muscle fibers. The higher frequencies (133-200 Hz) produce faster contractions and are therefore ideal for stimulating fast muscle fibers.
2500/4000/5000 Hz modulated at 4/6/8/12/50/75/100 Hz
The vomiting currents at 2500/4000/5000 Hz modulated at 4/6/8/12/50/75/100 Hz are often used for pain relief and muscle relaxation. The higher frequencies (50-100 Hz) generate fast and intense muscle contractions that can relax the muscles and reduce pain.
To summarize, Kotz currents are a special type of electrical stimulation that uses the square wave to create muscle contractions and uses specific frequencies to stimulate the muscles. They are often used by athletes and fitness enthusiasts to improve muscle strength and mass, and by therapists to rehabilitate muscles after injury or surgery.
However, it is important to note that the use of vomiting currents and other types of electrical stimulation methods may have contraindications in some cases and should therefore only be performed under the supervision of a qualified therapist or doctor. It is also important to use the correct technique and settings for the patient's specific needs in order to achieve maximum results and avoid injury.
There are many studies that support the effectiveness of vomiting currents in improving muscle strength and mass as well as pain relief and muscle relaxation. However, the results are not always consistent and more research is needed to determine the long-term effects and optimal use of vomiting currents.
