Physical activity is all the movement carried through for the body provoked for the contraction of the esqueltica musculatura, causing the increase of energy expense (ACMS, 2000; BOUCHARD, 2003). Already the physical exercise is a subclass of the physical activity, where a planning, a estruturao of the activities exists, in order to promote or to keep the levels of physical aptitude (ACMS, 2000). Currently the children have basses levels of daily physical activity.
