The almost unlimited supply of high energy density foods associated with sedentary lifestyles have led to the creation of an "obesogenic environment", the expansion becomes more evident, so in Ecuador, vital statistics show that four of the ten causes of death are diseases related to nutrition, affecting a significant number of both youth and adolescents (MSP, NORMAS DE NUTRICIÓN para la prevención primaria y control del sobrepeso y la obesidad en niñas,niños y adolescentes, 2011).
Sedentary lifestyle - "defined as the absence of exercise intensity - moderate to high 30 min / day at least 3 times a week" (Díaz, Saavedra, & Meza, 2007, pg. 6) in children and adolescents is worrisome, due to increased levels of development and the possibility of CNCD (Chronic Noncommunicable Diseases) in adult life.
By contrast, the recommendations of international agencies such as WHO (World Health Organization), is aimed at promoting healthy lifestyles both nutritional and physical, they represent by far factors for future prevention and control cardiovascular diseases, until recently, were thought unique to adulthood.
Despite the legal backing to the establishment of the Republic, and several programs to promote physical activity in the community, has not yet been carefully evaluated, and fewer still have reported their experience in the international scientific literature for positive impacts in terms of reduced levels of physical inactivity and obesity in school adolescents, so the incentives promoted by educational units programs would enhance much resolution of this problem (CDC EEUU, 2006, pg. 3).
