Measuring physical self-concept of schoolchildren aged 10 to 16 on physical education lessons

This research aim was to determine what happens to physical self-concept during compulsory schooling. 1419 students from Primary (n = 619) and Secondary School (n = 800) participated: 640 boys and 779 girls; Mage = 12.81, SD = 1.93. There were statistically significant differences in age and educational stage, regarding physical condition (PhC) (p < .001), appearance (AP) (p < .001), perceived competence (PC) (p < .001), strength (St) (p < .001) and self-esteem (SE) (p < .001); In the gender factor in PhC (p = .005). Results showed a decrease in PhC, AP, PC, St and SE in the passage from Primary to Secondary School, as these variables are higher in boys than in girls. Based on results, it should be reflected on teaching practice and methodology used in these ages, because physical self-concept is an important factor for becoming and remaining physically active
