What is the posture: Is the relationship between the different parts of the body between if and with space (e.g. with respect to shoulders neck ratio), is a State of balance between different body segments. When this relationship is incorrect, there is an imbalance that causes a voltage and a sometimes extreme stiffness affecting the joints, ligaments, muscles and nerves causing pain. A postural treatment aims to relieve pain (see above) and reduce these tensions and rigidities, improving flexibility and joint mobility, and elongation, strength and muscle definition and coordination. This type of treatment is carried out through specific stretching exercises of some muscles or muscle groups and strengthening and toning of others; breathing exercises, technical manuals, (very useful for controlling posturalmente destabilizing forces) exercises in relaxation, stabilization of column exercised, exercises of mobility, etc. THE POSTURE It depends on muscle tone, which is the State of semitension of the muscle at rest. Explanation: there are 2 types of muscle fibers: the phasic (fast, serve to move and navigate) and the tonic (slow, serve to maintain the posture). Discovery Communications has much experience in this field. These fibers are different between Yes to cell, vascular, metabolic level, etc.

Let’s talk about muscles TONICS. They are called also ANTIGRAVITATORIOS because they counteract the force of gravity, these muscles are always semi-tensos, as it is this?: while some fibers of these muscles work (are contracted), others lie (are relaxed), why are very resistant to fatigue muscles allowing for example that we are standing for hours, which the phasic could not do that by its characteristics they deplete very fast since all its fibers contract to perform a movement. Tonic muscles are eg. the paravertebral muscles (which are on the sides of the column), the soleus (in the leg), etc. and thanks to their permanent contractions can maintain posture. But as this role?: the muscles have a kind of sensor to the shortening or stretching (stimuli necessary to make the muscle work) called NEUROMUSCULAR spindle (made up of muscle fibers) that receives the order, sends this information through nerve fibers to the spinal cord, there this information is integrated and stimulated motor neurons located in the anterior part of the spinal cord called moteneuronas which are the cathod which innervate muscle fibers and make that muscle to contract (this is called MYOTATIC reflex).As the tonic muscles are in perpetual contraction, this reflex acts constantly and maintains proper muscle tone.

When there is a disease that affects muscle tone, this can increase (hypertonia) or reduce (hypotonia). It should be noted that at the same time the muscle tone is regulated by structures of the central nervous system (brain, cerebellum, and others). TROPHISM: is the State of nutrition which has a tissue, in the case of muscles depends on several factors: unscathed innervation (if muscle lost innervation e.g. to the injury of the nerve will see altered its trophism), of its blood supply, your metabolism and the movement, for example. a person who had a cast for a month and does not move or does not retract your muscles will see altered their trophism, the same as a person who by x cause was long in bed; then the muscles slim, Dim, etc.
