School-based Intervention to Promote Physical Activity in Adolescents in Spain: the Promoting Physical Activity in Secondary School For Health Project

Previously an initial measure (qualitative and qualitative) will be made to know the little active adolescents. At the end of the physical activity program a retention measure will be carried out to know the scope and persistence of the variables analyzed. The intervention will be developed with a frequency of three weekly sessions, of 60 minutes, in the period of the intervention, with the exception of weeks in which there is a public holiday, where there will take measures to recover the class. A schedule for the sessions will be set according to the interests of the participants and will be the same for all.
