Well-Being and Vitality

That feeling of well-being, vitality and joy that takes place in many occasions, like when sport practices has a biochemical origin, part of which is produced by a called substance endorfina. The endorfinas are peptides (small proteins) derivatives of a precursor produced concerning the hipfisis, a small gland that this located in the base of the brain. When we make sport this gland is stimulated, taking place endorfinas in the organism, those that are going to act on the receivers that cause analgesia, besides producing a similar sedative effect to which it generates morphine, opioide exogenous coarsely known by these same properties. It is by that the endorfinas are considered our opioides endogenous, that is to say, produced by our organism. The studies demonstrate that the endorfinas are able to inhibit the nervous fibers that transmit the pain, besides acting at cerebral level producing subjective experiences, that are intense sensations, known well by the sportsmen as they are the diminution of the anxiety and the well-being sensation. Besides the analgesia and sedation indicated above.

Not only the sport is a stimulus that makes us secretar endorfinas, since in certain situations of stress also its production like in the sexual acupuncture, relations, the suggestion and also in certain ritual or ceremonial dances has been verified. It is difficult to establish what of these activities is the one that better stimulates the production of endorfinas. Nevertheless this demonstrated that the resistance exercises, yes produce a significant increase in the secretion of endorfinas. Numerous studies have demonstrated that after to have produced aerobic physical activity, it exists clearly and significant increase of the endorfinas after the exercise. In runners of long distances it has been managed to revert the analgesia produced by the exercise, administering inhibiting of morphine. What demonstrates that they use the same physiological receivers and in addition the roll of the endorfinas like analgesic is verified in these athletes.
