With the development of science and technology, artificial intelligence has risen in the field of education. The combination with youth physical education brings new opportunities and challenges. This study deeply explores the effective paths and impacts of integrating artificial intelligence into youth physical education. Artificial intelligence can realize comprehensive monitoring and data analysis of students' sports, provide all-weather sports guidance and tutoring, and timely feedback and comparison of sports achievements. In terms of theoretical basis, it elaborates the overview of artificial intelligence technology and the demand analysis of youth physical education. In application practice, it introduces the application of artificial intelligence in classroom teaching and extracurricular exercise, including intelligent auxiliary teaching systems, sports skill assessment and feedback, the role of extracurricular exercise platforms, and the formulation of personalized exercise prescriptions. Through case studies, it analyzes intelligent running training systems and personalized basketball exercise prescriptions. The research conclusion shows that artificial intelligence has a positive impact on youth physical education, including innovative teaching methods and optimized extracurricular exercise. Future research can be carried out from expanding application scenarios, strengthening interdisciplinary research, and solving problems.
