PHYSICAL RECOVERY IN SPORT PERFORMANCE WITH  

MANDIBULAR STRETCHING

(summary information)

1.FOREWORD

During a race or workout the athlete is subdued to a psycho-physical stress, which  encreases

-                     Heartbeat pulsation;

-                     Blood pressure;

-                     Muscle tone;

-                     Mental effort.

Only at the end of performance (race or workout) the heart and pressure parameters bring back to pre-stress values; this is possible thanks to recovery.

When the recovery is not optimal, the fatigue remains; the athlete feels an agility and reflex reduction, could have muscle contractures with possible muscle-tendon complications (Ex. Pubalgie) and/or osseous complications (Ex. Microfratture), performance capacity reduction as well.

In those conditions the subject exposes himself to a high risk of sport accident.

2 TO INCREASE THE PERFORMANCES

In order to enhance the performances, every sport has got its own training method, its own lenght of time, places. Surely all the sports have in common one thing: the need for relaxation to obtain the best refreshment.

To encrease the performance, therefore, a path to take with the confidence to have good results is surely to obtain a heartbeat pulsation, blood pressure, muscle tone and mental effort recovery as much as possible.

Studies and tests have dimonstrated that the mandibular stretching activity, never used up to now in sport, takes advantages as actual as unexpected.

If with our mind we recollect many sport images, we could immediately remember how the athlets, in the maximum of their performance, grit their teeth: they close them in a spasmodic way.

This is not only a personal attitude: gritting the teeth for one minute permits the body to reinforce the stress mechanisms and to encrease the medium arteria blood pressure of  5,5 mm hg. (http://www.ncbi.nlm.nih.gov/pubmed/277577).

This fact gives the athlet to express at his best the sport performance.

The open mouth pleasant yawn image is likewise clear and as much as the tightened mouth is associated to the stress, the open mouth which yawns is associated to relax concept.

This study has been presented into the sperimental thesis work of COPPI, ERIKA Study of trigeminal-cardiac reflex in the arteria blood pressure and hearthbeat pulsation control (http://etd.adm.unipi.it/t/etd-04072010-114646/)

This has been done with sperimental prototype of medical device called Spring device and has been published (http://www.ncbi.nlm.nih.gov/pubmed/23479456)

Watching this image is perceived that the mandibular stretching is an action mechanism that can already found in nature without either realizing.

3 THE INSTRUMENTS TO ENCREASE THE PERFORMANCES

For the mandibular stretching studies and tests has been used the ”Spring Device” (Image 1 and 2), a device that permits to do a mandibular extention in association with masticatory movements, in practice a mandibular stretching activity. Tests have demonstrated that the use of this device, otherwise the mandibulary stretching activity, permits a heartbeat pulsation and blood pressure decrease (in the human being) and that it ecreases the quantity of blood that flows into the brain (in the vertebrate). It is afterwards conceivable that this activiy can even favour the mental recovery work, which is fundamentally important in the sport performance.

4 CONCLUSIONS

Latest studies have proved that the use of dinamic mandibular stretching permits the body the quickly recovery of the physiological parameters that the athlet has got before performance.

The use of medical device “Spring Device” permits to do the mandibular stretching and so permits the athlets to recovery quickly.

The “Spring Device” acts through totally natural mechanisms, therefore it is not considered sport doping in any way.
