Background and Aim: Promoting physical activities is crucial for maintaining overall health, reducing the risk of chronic diseases, and improving mental well-being. Regular exercise enhances strength, flexibility, and endurance, leading to a more active and fulfilling life. This study examines the impact of China's "Double Reduction" policy on extra physical activities (EPA) in secondary schools. As the "double reduction" work continues, schools have more time to organize extra sports activities, and students' demand for diversified extra sports activities has also become stronger. The objectives of this study were 1) to survey the current situation of extra physical activities and 2) to develop guidelines to promote extra physical activities under the "Double Reduction Policy" in secondary school. 3) to evaluate the effectiveness of guidelines to promote extra physical activities under the "Double Reduction Policy" in secondary school. Materials and Methods: The research was a mixed-method research and development study. The methodology was phase 1) A survey of a simple random sampling of 60 teachers and purposive sampling of 5 experts in Lishui City secondary schools examined the impact of the "Double Reduction" policy on extra-curricular physical activities. Phase 2) Develop guidelines with a focus group comprised of 11 experts with purposive sampling, developing a draft guideline to promote extra physical activities under the "Double Reduction Policy" in secondary schools. Phase 3) to confirm guidelines by connoisseurship with purposive sampling of 7 experts. The statistics were mean, standard deviation, and frequency to analyze data. Results: The results found that 1) Survey of Current Situation: The survey results, obtained through the PNI questionnaire and expert interviews, indicated a generally positive attitude towards promoting extra physical activities under the "Double Reduction Policy." However, the study identified areas for improvement, particularly in teacher involvement and external collaboration.2) Development of Guidelines: The guidelines were developed using the POLC framework (Planning, Organizing, Leading, Controlling) to provide a comprehensive approach. The planning phase included conducting student surveys, developing yearly activity calendars, and setting participation goals (3 action plans, 3 indicators). The organizing phase focused on allocating time slots, arranging facilities, recruiting instructors, and establishing communication channels (4 action plans, 4 indicators). The leading phase aimed to create a supportive environment, promote activities, recognize achievements, and organize events (4 action plans, 4 indicators). The controlling phase involved monitoring participation, gathering feedback, tracking impact, ensuring safety, and evaluating effectiveness (5 action plans, 5 indicators).3) Evaluation of Guidelines: The connoisseurship assessment found that all experts accepted the guidelines as practical, reliable, and suitable for implementation. Each component of the guidelines received a strong average rating between 4.57 and 4.86, indicating high levels of acceptance and perceived effectiveness. Conclusion: The guidelines developed using the POLC framework provide a comprehensive approach to promoting extra physical activities in secondary schools under the "Double Reduction" policy. The high acceptance ratings from experts (4.57-4.86) indicate the practical value and potential effectiveness of these guidelines. By addressing planning, organizing, leading, and controlling aspects, schools can implement structured, engaging, and sustainable physical activity programs that contribute to students' holistic development.
