The electro stimulation is a technique that provokes a muscular contraction
completely similar to the volunteer one, using electrical TENS impulse. There are two
different ways of use:
- Muscular stimulation (ideal for the development of the force and for
aesthetic treatments)
- The stimulation to nervous ends (ideal for the treatments against the
pain).
Types of muscle
The muscle can be subdivided in three different types: streaked or voluntary
muscle; cardiac muscle and smooth or involuntary muscle.
The voluntary muscle includes the skeletal muscle that gives movement to the
skeleton and the cutaneous muscle that acts on facial expressions.
The cardiac muscle and the smooth muscle are not voluntarily controlled. The most
part of the muscles of the human body belongs to the category of streaked or
voluntary muscles, with approximately 200 muscles for every side of the body
(approximately 400 in total).
Skeletal muscles are the target of the EMS.
Mechanism of the muscular contraction
The skeletal muscle exercises its functions through the mechanism of the
contraction. When the muscular contraction happens, the movement of the
articulations is produced and consequently the movement of the skeleton, too.
The muscle contracted in the following way: when a person decides to make a
movement, an alteration of the electric potential in the motor center of the brain
and an electric impulse is transmitted to the muscle that has to move.
The electrical impulse is transmitted as a change of potential (voltage); an
electrical impulse crosses the motor nerve to the muscle that must be stimulated.
After the reception of the impulse, Ca ions are freed by the reservoirs causing the
approach of actin and myosin. The result is that the distance between the bands Z
diminishes causing therefore the muscular contraction.
The energy demanded for the contraction is supplied by the supply of sugars and
fats stored in the human body. In other words, the electrical stimulation is not a
directed energy resource but it works as an instrument that triggers the muscular
contraction. The same type of mechanism is activated when the muscular
contraction is produced by the EMS.
