Electro stimulation: advantages and ways of application
Perhaps not everyone knows what is theelectro stimulation, is a technique that, using the impulses that act or on the muscles or nerve endings (pulses TENS), causes a muscle contraction is very similar to that voluntary, can be used in three different ways:
1° muscle stimulation, ideal for developing strength;
2° stimulating nerve endings for pain treatments and beauty;
3° iontophoresis, ideal to direct the drugs.
The most suitable instrument for electrostimulation is a constant current generator that:
- rectangular pulses have compensated and symmetrical, the so called pulses TENS (transcutanic electric nerve stimulation) and pulses of iontophoresis,
- be able to adapt to the resistance of different tissues (for example skin and FAT), which lie between the electrodes and the muscle to be stimulated,
- have programs where the impulses are calibrated according to two variables: frequency (pulse per second in Herz), which must be between 1 and 120 Hz, and the chronaxy! * *, that is, the pulse width, measured in microseconds (from 30 to 450).
But what are the advantages the use of electrostimulation? You have to tell them apart for several areas:
Sport: workout of muscle fibers usually rarely used under normal working sessions, lower recovery time, isolation of the muscle group treated, safeguarding of the musculotendinous system, mental and physical energy saving, using more muscle fibers than the voluntary contraction, absence of overhead for the joints, blood circulation better, activation of endorphins;
Rehabilitation: treatment of posttraumatic and postsurgical muscle reduction, motor recovery, recovery of muscle strength rebalancing of proprioceptive control, care of contractures;
Aestheticscapillary microcirculation improvement, mobilization of fats, drainage of liquids, increased metabolism and cellular activities, reduction of fat deposits and cellulite, toning and firming of tissues;
Club: pain reduction, increase endorphins, maintaining muscle tone.
A full program of stimulation must follow this path: warm-up, workout, cool-down.
What are the programs present in an electro-stimulation?
- Development of strength: stimulation of fast fibers mixed anaerobic and aerobic metabolism
- Development of explosive force: for enhance maximal force and strength fast
- Development of resistance: for enhance resistance to intense effort
- Toning: to improve muscle tone through the stimulation of slow fibres (involves long lead times of contraction at low frequencies)
- Active recovery: to speed up recovery after a race or a workout
- Capillarisation: to increase blood flow
- Lipolysis: to stimulate the mobilization of fats and the drainage of fluids
- Pain relief: to reduce pain by stimulating nerve endings with MIDs
- Endorphinic: for the release of endorphins through stimulation at frequencies
- Disuse atrophy: to retrieve the volume of muscle stimulating the slow fibres
- Muscle relaxant: for an action of tonolisi.
The stimulation is used for isometric muscular work; the intensity should always be below the pain threshold, especially for analgesic purposes TENS, where underlying muscle tissue stimulation should be avoided.
Electrostimulation has no contraindications, it is prohibited to wearers of pacemakers, pregnant women and epileptics, and is still recommended to consult your doctor before using any equipment to any stimulation.
