the close relationship between the motoneuron (tonic or phasic) and the functional
characteristics of the fibers it innervates and they have shown as a specific motor
activity (particularly sports) can bring about a functional adaptation of fibers and a
change in their metabolic characteristics.

Stimulation intensity
The current intensity necessary to obtain muscular contraction is personal and
depends on the position of the electrodes, the underlying adipose tissue, sweating,
the presence of hair on the area to be treated, etc. For these reasons, the same
current intensity can generate different feelings from person to person, from day to
day, and from the right side to the left side of the body. During the same working
session, it will be necessary to regulate the intensity in order to obtain the same level
of contraction because of the accommodation phenomena. The current intensities
recommended in the different phases are proposed as indicative values, and each
person should modify these levels according to his/her personal needs.
- Moderate intensity. The muscle does not tire, not even during prolonged
treatments. The contraction induced is tolerable and pleasant. This is the first level
on the graphic representation of intensity.
- Intermediate intensity. The muscle is visibly contracted but the stimulation does not
cause the joints to move. This is the second level on the graphic representation of
intensity.
- Elevated intensity. The muscle is contracted substantially. The muscular contraction
will cause the extension or bending of the limb if this is not blocked. This is the third
level on the graphic representation of intensity.
- Maximum intensity. The muscle is contracted maximally. This is an intense
treatment that should be performed only after having executed different
applications at lower intensity.
