Motor self-efficacy, self-concept and BMI in Physical Education adolescents for optimal physical and mental health

As society progresses, physical activity is becoming increasingly important for mental and physical health. Physical inactivity and sedentary lifestyles are epidemic among young people, and cases of obesity and other noncommunicable diseases are on the rise, affecting the physical and mental health of young people. For this reason, this study investigated the associations between self-concept, motor self- efficacy and Body Mass Index (BMI) as a function of sex and school location. The Kolmogorov-Smirnov test was applied to apply non- parametric tests, Spearman's Rho for correlations between self-concept and motor self-efficacy and BMI, in addition to a regression test and, finally, Cronbach's alpha coefficient. The results showed significant associations between PA-5 and AEM, particularly in the physical dimension. As for BMI, the correlation was inverse and significant only in boys and urban settings. These concepts can have an impact on the adoption of healthy practices at both the individual and community levels, contributing to health promotion and maintenance. The interaction of these elements is complex and diverse, and addressing them appropriately can have a significant impact on the overall health of the individual and society as a whole.
