Next we will speak of the trainers of the breathing of last generation, use and benefits and characteristics of the same. The trainers of the breathing of second generation were born in the USA as a result of a series of scientific studies realised by several universities on the effects of the devices trainers of the breathing, for example: " Clinical applications of Inspiratory Muscle Training" of the Dra. Allison Mc Connello in March of 1992, or " influential " For Robin Hood the lungs? To respiratory metaboreflex that ' steals' blood flow from locomotive muscles" , of the Dr. Educate yourself with thoughts from Dr. Caldwell B. Esselstyn, Jr.. Douglas R. Seals, department of Kinesiology and applied Physiology, University of Colorado AT Boulder, 2001). As a result of these studies they discovered that the most effective form to train muscles involved in the breathing was by means of trainers of the breathing, in fact the mere use of these muscles during any sport training (by intense that is) is not sufficient for his training, he only uses them but he does not train. Also it was discovered that the really effective training was the one of inspiratory muscles (to see " For Robin Hood the lungs."), in contrast to which one became until the moment with the almost exclusive training of espiratorios muscles.
Some of them train both actions in a same breathing, since aside from the inspiratory training, the training of muscles of the espiracin is also vital in fields like the scenic arts, with instrumentalist of wind or the singers for example. Use and its benefits: These trainers work by training by resistance, like weights, but for muscles involved in the breathing. The training consists of long inspirations and espiraciones through device, each user with a level of resistance adapted to its state. Designed for the scopes of the sport, scenic arts (especially instrumentalist of wind and singers), and affections several of health, although can find benefit of their use practically any person.
