This study evaluates the effectiveness of a school-based calisthenics intervention in promoting physical activity and improving health-related outcomes in adolescents. Physical inactivity during adolescence is a growing public health concern associated with increased risks of obesity, poor physical fitness, and reduced psychological well-being. Schools provide an optimal environment to implement structured interventions that encourage lifelong healthy habits.
Calisthenics is a form of exercise that uses bodyweight movements to improve strength, flexibility, and coordination. It is cost-effective, accessible, and does not require specialized equipment, making it particularly suitable for school settings. The present study integrates a structured calisthenics program into regular physical education classes.
A total of 100 students aged 13 to 16 years will be randomly assigned to either an experimental group, which will participate in the calisthenics program, or a control group, which will follow the standard physical education curriculum. The intervention will last 12 weeks, with three sessions per week.
Primary and secondary outcomes will be assessed at baseline and after the intervention. These include physical fitness (muscle strength), body composition, dietary habits, and self-concept. Strength will be measured using a handgrip dynamometer, body composition through anthropometric assessment, dietary habits through a validated questionnaire, and self-concept using the Self-Concept Form-5 (AF5).
Findings from this study will provide evidence regarding the feasibility and effectiveness of implementing calisthenics in school settings as a strategy to improve both physical and psychological health in adolescents.
