This study investigates the dilemmas in the development of youth sports. The results show that despite the high attention paid by the Party and government to the work of youth sports, there are still realities such as a decline in the physical health level of adolescents, inadequate implementation of school sports work, and a reduction in the scale of talent training for competitive sports. On this basis, strategic measures for the sustainable development of youth sports are proposed: strengthening the construction of youth sports regulations and systems, deeply carrying out school sports work, further strengthening the construction of youth sports clubs, and improving the training system for competitive sports talents.
