It is known that functional training is supported by the proposal to improve neurological aspects that lead to the functional capacity of the human body, using exercises that stimulate the different components of the nervous system, thus generating its adaptation (SILVA, 2011; CAMPOS and CORAUCCI NETO, 2004).
According to Clark (2001 apud DIAS, 2011), functional movements refer to associated, multiplanar movements that include reduction, stabilization and force production; that is, functional exercises refer to movements that employ more than one body fraction simultaneously, which can be performed in different planes and involving different muscle actions (eccentric, concentric and isometric). In other words, functional training works movements, not muscles in isolation, thus involving all physical capacities - balance, strength, speed, coordination, flexibility and endurance - in an integrated manner through multi-joint and multi-planar movements and in involvement of the proprioceptive system, the latter, according to Ribeiro (2006 apud SILVA, 2011) related to the sensation of movement (synesthesia) and joint position, and among the main functions of this system are the maintenance of balance, the orientation of the body and the prevention of injuries.
Thus, it is clear that functional training involves specific movements for the development of the individual's daily life activities. Therefore, this training methodology enables all audiences to have good physical conditioning conditioning, thus making it possible to achieve excellence in performance
It is undeniable that functionality has always been present at all times in human evolution. Man has always needed to efficiently perform day-to-day tasks, thus ensuring survival in often adverse situations. However, with technological evolution, the ease and comfort for carrying out actions that were previously essentially physical made man less functional (CAMPOS and CORAUCCI NETO, 2004).
Functional training represents a new conditioning methodology, guided by the basic laws of training and scientifically supported through research and bibliographical references in all its main points and, above all, extensively evaluated in the training rooms, where it was possible to define its basic lines . However, the essence of functional training is based on the progress of neurological aspects that compromise the functional capacity of the human body through stimulating training that challenge the various components of the nervous system and, therefore, generate its adaptation (CAMPOS and CORAUCCI NETO, 2004 ; D'ELIA and D'ELIA, 2005).
Thus, it is understood that training, whether resisted or functional, will generate positive adaptations to the practitioner's body, provided that they are addressed in a way that meets the training principles, each within its characteristics, enabling the practitioner to have better quality of life.
