The implementation of the “double reduction” policy is a product of China’s vigorous reform of theeducation mechanism in recent years. It provides systematic guidance for the increase in student learning load and thedecline in physical health, the explosive spread of off campus training institutions, the chaotic market developmenttrend, and the growing learning needs of students. This article adopts literature review and logical analysis methodsto analyze the development challenges faced by youth sports training institutions under the “double reduction” policy,and proposes corresponding measures. Research suggests that the development of youth sports training institutionsis limited by insufficient venues and teaching staff, poor teaching quality, unclear management personnel, andinadequate policy support for the governance of the institutions. Research suggestion: Institutions should strengtheninternal management, ensure the conditions of venues and teaching staff, improve teaching quality, and build anexternal governance system to provide policy support.
