The Mediating Role of the Self-Concept Between the Relationship of the Body Satisfaction and the Intention to Be Physically Active in Primary School Students

The aim was analysed the extent to which anthropometric values, in line with body image and physical ability, predict physical self-concept and the latter in turn predicts the practice and intention to pursue physical activity. A total 302 participants, 150 males and 152 females were recruited from different primary Schools in Extremadura (Spain). The age of the participants ranges of 10 – 13 years old (M = 11.74; SD = .86). The indirect effects of the model showed significant relationship between physical condition (p = .001) and PA levels, according to the perception of self-concept (β = .231, 95% BcCI = [.055, .212]). However, anthropometric variables proved not to be related to any significant extent (p <.05). The second level covered the indirect effects between the intention to be physically active and self-concept, which showed a significant relationship between the perception of self-concept (p = .000) and the intention to be physically active. Lastly, the third level showed significant relationships between physical condition (p = .001) and the intention to pursue physical activity. The present investigation concluded that physical condition, anthropometric variables and body image predict the perception of physical self-concept in adolescents.
