Summary
This study introduces an 8-week Posture Education Program (PEP) for adolescents, integrating posture, exercise, and behavior to improve physical health and well-being in schools.
Area of Science:
- Public Health
- Pediatric Health
- Exercise Science
Background:
- Adolescents face increasing sedentary behaviors and poor ergonomics, negatively impacting posture, aerobic capacity, and psychological well-being.
- A standardized protocol is needed to evaluate interventions addressing these issues in school settings.
Purpose of the Study:
- To describe a protocol for an 8-week Posture Education Program (PEP) for high school students (aged 14-17).
- To evaluate the program's impact on posture, aerobic capacity, lung function, and psychological well-being using a randomized controlled trial design.
Main Methods:
- The intervention, developed using the ADDIE framework, includes postural awareness, core strengthening, ergonomic correction, and behavioral activities within physical education.
- A randomized controlled trial design compares the PEP group with a control group receiving standard physical education.
- Outcomes are assessed using the International Classification of Functioning, Disability and Health (ICF) framework, measuring primary outcomes (postural alignment, aerobic capacity, lung function) and secondary outcomes (physical activity, psychological well-being, ergonomic knowledge/behavior).
Main Results:
- The protocol outlines a structured, reproducible framework for school-based posture education.
- It integrates multidimensional assessments of physical, cardiorespiratory, behavioral, and psychological outcomes.
- The study is designed to provide robust data on the effectiveness of posture education interventions in adolescents.
Conclusions:
- This protocol offers a reproducible model for implementing and evaluating school-based posture education programs for adolescents.
- The intervention aims to mitigate risks associated with sedentary behaviors and poor ergonomics.
- Multidimensional assessment ensures a comprehensive understanding of the program's effects on adolescent health and well-being.
