📌➡️The principle of electrical stimulation consists of stimulating the nerve fibers by electrical impulses that are transmitted through the electrodes.
➡️In active training muscular work comes from the brain, which sends the command in the form of electrical signals to nerve fibers that contract.
➡️ The principle of electrical stimulation corresponds exactly to the process that takes place at the desired contraction. The stimulator sends an electrical current impulse to the nerve fibers, which causes their irritation. This irritation is submitted further to the muscle fibers that perform elementary mechanical response (muscle twitch) as an essential element of muscle contraction.
➡️ The reaction of the muscle is fully synchronized with the work of the muscles from the brain.
➡️In other words, the muscle cannot distinguish the command from the stimulator from those from the brain.
➡️ Various parameters (number of impulses per second, the duration of contractions, the duration of resting stages) allow different types of muscles to start working, depending on the muscle fibers.
➡️Fast fibers will be more prevalent among sprinters while marathon runners will have more slow fibers.
➡️ Knowledge of human physiology and a perfect mastering of stimulation parameters of the program allow very precisely the work of muscles to be directed to the desired objective (to strengthen muscles, increase blood flow,
mounting).
➡️To achieve the pain relief effects the
electrical impulses can also arouse sensitive nerve fibers. The stimulation of nerve fibers blocks the transfer of the pain through the nervous system, in contrast to the stimulation of some other types of sensible fibers which causes an increase in the production of endorphins alleviating pain.
