Physical self-concept which is the most important constituent of personality in adolescents, is the mental image of each person in his or her body. One of the challenges of adolescents is their body changes due to maturity and their attitude towards their body. The aim of this study was to determine the relative contribution of puberty and physical activity in explaining the physical self-concept of adolescent females.
A number of 1630 students (1090 non-athletes and 540 athletes), aged from 10 to 16, were randomly selected from different regions of Tehran. Students received sufficient information about research, then they completed consent form, personal information (including birth information, educational background, age of menarche, mental and physical health and athletic background), and physical self-description questionnaires.
The results of regression analysis showed that among the puberty and physical activity variables, the physical activity significantly explains 12% of the changes in physical self-concept, and the puberty significantly predicts only one percent of physical self-concept. (p<0/001). In fact, according to the regression model, both physical activity and puberty variables are capable of explaining and predicting physical self-concept, but the contribution of physical activity in changing physical self-concept was more than puberty.
According to the results, it can be concluded that physical self-concept is related to physical activity and puberty and participation in physical activity improves physical self-concept. The results also support previous research in the field of effective role of physical activity in physical self-concept, increased the internal validity of the literature.
