This study examines the current state of youth physical fitness in China and proposes strategies for improvement. The methodology involves a comprehensive analysis of existing policies, infrastructure, and educational approaches to physical fitness. A multifaceted approach was used, including quantitative assessments of fitness levels in different regions and qualitative assessments of policy effectiveness. Data were collected through national surveys, physical fitness tests, and interviews with educators and policymakers. Results show that while there has been some progress in improving adolescents' physical health, significant disparities persist, particularly between urban and rural areas. Notable issues include high rates of nearsightedness, obesity, and early onset of chronic disease. The analysis also highlights gaps in the integration of physical education into broader education policies and the need for improved coordination among stakeholders. The study concludes with specific recommendations, including improved sports infrastructure in rural areas, more effective physical education programs, and increased public awareness of nutritional health.
