WITH TTVIB IT IS EASIER TO HOLD THE POSITION

How to improve the posture during the match


When you start playing table tennis the first thing that is taught is body positioning, that is, what position you need to be in at any stage of the game. Learning to position the body in a globally flexed stance is the prerequisite for hitting the ball properly. In fact, if for various reasons, the flexed position of the body is lost, the shot in most cases is wrong. It usually goes out of scope.

The posture
 
The positioning of the body is also defined Posture, which is the most suitable position of our body in space that opposes the force of gravity, in the most economical way possible from an energetic point of view.
 The concept of energy expenditure is therefore fundamental in a sport like table tennis which today takes place at high intensity, both in terms of rhythm and endurance. Not infrequently, in fact, to win a point you need four, five, six exchanges, made with rapid movements and with the Posture always adequate to be successful usually with the Counter Forehand Top.

In order to have an optimal posture in all of the phases of the game, it is essential to have an efficient muscle tone that guarantees the best contractility of the muscular system. In high-level competitive table tennis, as a result of the overstresses to which the motor system is subjected, tonic alterations of the muscular system often occur, ranging from simple contracture up to actual retraction, for which the player perceives both at rest and under stress muscle stiffness.

In these cases, the postural attitude is constantly negatively affected during movements and the movement will not be as fast and fluid as it should be. And, consequently, there is a lengthening of the reaction times.
Therefore, Tone and Posture are closely linked and interdependent.

The muscle tone
 
Muscle tone is that slight and continuous contraction of skeletal muscles that is always present regardless of movements. It is due to the presence of nerve reflexes that occur in the spinal cord by means of stimuli that come from muscle receptors, as well as vestibular and visual ones. These reflexes are controlled by higher nerve structures such as the cerebral cortex, cerebellum and cerebellum. What is the central problem of posture in table tennis? It is the difficulty of "maintaining" the flexed posture of all parts of the body during movements, or the correct positioning, and it is due to the constant relationship between the width of the support base and the height of the center of gravity.

An indispensable information channel to optimally "maintain" the Posture is represented by the proprioceptive sensory system. The proprioception is due to specific receptors, called proprioceptive or kinesthetic receptors, sensitive to variations in the postures of the body and body segments, which send their signals to some particular brain areas. The proprioceptive receptors are made up of the nerve endings that initiate the neurophysiological process of proprioception.

Through this system there is the tonic contraction of reflex origin of the antigravity muscles necessary for the realization of the postural structure. In particular, in order to have a correct posture, it is necessary to have a continuous processing of the muscle toning activity parameters so that the center of gravity always remains within the support base. Therefore, according to how the muscle tone is regulated, so there is the adequate tension for maintaining the positioning in order to produce, for example, a high speed movement. With each movement, therefore in our case, with each movement, the positioning adapts and therefore the balance between tone and posture is continuously modified.

The cerebellum
 
The thing in charge of this function is the Cerebellum which, through the information received from the proprioceptive Sensitivity, produces an automatic adaptation of the Posture. In particular, it intervenes to ensure the right balance between the activity of the agonist and antagonist muscles of the trunk and joints during rapid changes in movements. By doing so, it produces continuous postural adjustments in order to maintain the body's balance in space.

This is possible thanks to the incoming and outgoing nervous connections with the cerebral cortex from which it is informed, almost in real time, of the variations in position of the limbs, of the body and of the individual parts with respect to the trunk. In this way, the Cerebellum can modify the muscle tone or influence the cerebral cortex in an inhibitory mode, from which the input to the movement pattern starts.

TTVib
 
In light of the above, with regard to the close neurophysiological relationship between muscle tone and posture, it is clear how important it is to "train" the tone by strengthening the proprioceptive system. TTVib, vibration for table tennis, with dedicated frequency programs for table tennis, is a specialized instrument for nerve stimulation of proprioception. In fact, it activates the muscular nerve sensors such as the neuromuscular spindle, which sends significant information to the spinal cord and from there to the cerebral cortex.

The sensorimotor cortical area corresponding to the stimulated muscle is excited and produces a new tonic input to be sent to the periphery to program the motor pattern, for example, of the movement. At the same time, a process of tonic control of the action is also activated which is entrusted to the Cerebellum, which, through its nervous connections with the Cortex, can correct the excitatory executive modalities of a movement.
 
The cerebellum does not play an active role in the execution of individual motor acts but it controls the sequence for the realization of the complete movement. In essence, therefore, having an optimal tonic condition through the TTVib vibration means having the ability to maintain the positioning better and for as long as possible. Better because the Cerebellum adapts the positioning in an increasingly finer way as it receives more targeted information from the neuromuscular spindle and longer because there is a greater balance between agonist and antagonist muscles involved in rapid multidirectional movements.
