However, due to the brutalgrowth of sports training institutions, weak teachers, disorganized powers and responsibilities of relevant regulatorydepartments, and the single content of institutional training, the sports training market is in the initial stage ofdevelopment. Therefore, combined with the specific requirements of the “double reduction” policy, the sustainabledevelopment path is proposed, including improving the access system of the sports training industry, strengtheningthe construction of teachers, actively improving the relevant policies, improving the institutional training system, andachieving good governance of the industry.
