Veinticinco años de análisis del comportamiento deportivo de la población española (1980-2005)

The study of the Spanish population sport behaviour from the beginning of the democratic transition until de middle of the first decade of the XXI century, relies on a strong theoretical and empirical basis, six national social surveys that cover the 2005-1990 period. All the six sport social surveys have the same sponsorship, the Sport Council (CSD), the same Institute of Social Research (CIS), and the same author, the one that has prepared the present article. The longitudinal analysis of the main results allows to frame, both theoretically and empirically, the advance of the posmodernization processes in the Spanish sport social system as well as in the sport behaviour of the Spanish population.
