At the beginning of the XIX century, health in the curriculum was based on hygienist purposes due to the industrialization process in which the society was immersed. One of the indicators is the inclusion of this content in the school curriculum through the subject of Physical Education. Health has increased his importance in the society. This makes necessary to know more about the living conditions of the people and their habits in order to understand, in this way, their health condition. The other aspect, more positive, is the integration of the concept in different dimensions, very often isolated. With regard to this definition, very few people would be considered as healthy. One of them, the less positive, embraces the concept as perfection when highlights a complete state of well-being marked by optimum physical, mental and social dimensions. According with Pastor-Vicedo, Gil-Madrona, Prieto-Ayuso and González-Villora (2015), although the recent definition is more complete than the previous one, the concept of health provides two well differentiated aspects. Whilst some decades ago such a term was defined as the absence of disease, nowadays it is understood as the complete physical, mental and social well-being ( WHO, 2006). The changes produced in the concept of health modifies the way it is understood.
