摘要：Few studies have so far examined the relation between Self concept, the variables linked to identity development and physical activity. The action-research wants to investigate the effects of specific training, based on the physical activity practice, on Self concept, physical and social self-esteem, self-efficacy, interpersonal psychological adjustment and meta-cognitive processes. Pre-adolescents from 11 to 14 years of age were involved in physical activities and educational itineraries. Results show that physical fitness may provide more positive social feedback and recognition from peer groups, and this will subsequently lead to improvement in an individual's self-image.
