Since the second half of the 20th century, changes in the habits of the general population have been observed, namely with regard to food and active behaviors (M. Silva, Vettoretti, & Thomazello, 2010).The diet started to include foods with a higher sugar, fat and salt content. This change, associated with a sedentary lifestyle (with a reduction in physical activity among children and young people, with 80% of the adolescent population being insufficiently active) (Mackenzie, Son & Eitel, 2018).These factors have caused an increase in obesity in the entire population and children are no exception. About 60% of children are overweight or obese (Spenser & Wrigth, 2014; Ferreira, 2015; Mackenzie, Son & Eitel, 2018).Portugal stands out as one of the countries with the most cases of obesity in Europe, in which 31.6% of children are overweight and more than 13.9% are obese (Rito & Graça, 2015). by the American Academy of Pediatrics and the World Health Organization (Spenser & Wrigth, 2014; Ferreira, 2015) classify obesity as a 21st century epidemic, as it is a public health problem.Ferreira (2015) highlights several changes that have occurred over time that have resulted in more inactive children, with less outdoor activity, in favor of children who spend more time indoors, with a high percentage of sedentary lifestyle and increasingly eating habits. hypercaloric.Lopes and Neto (2014) refer that there has been a reduction of this type of mobility in the last decades in several countries, such as Portugal, England, Australia and New Zealand. They establish a relationship between this factor and urbanization that led to a change in socio-cultural behavior in the most industrialized countries
