As a result, many schools have made fundamental changes in physical education activities. These policies are mainly aimed at getting young people to be more active and autonomous in school sports. This requires physical education training teachers must adhere to the people-oriented, student-oriented, so as to highlight the subject status of students. Based on this, students should establish a good sports values and ethics and form a good habit of lifelong sports, so as to further promote the sustainable development of youth sports activities. Based on the ecological theory of sustainable development as the background, this study constructs a unified theory of Unified Theory of Acceptance and Use of Technology (UTAUT) model for the sustainable training and development of youth skating sports training institutions. This study selects the youth skating sports training institutions in Beijing, China as the investigation object, covering small, medium and large institutions of different sizes, and analyzes based on the statistical data in 2023 and the results of field research. The results show that the application of this model not only increases the willingness of youth skating training institutions to continue to participate by 3.66%, but also promotes the diversified development of youth skating training. In addition, this study also discusses the environmental protection measures implemented in the process of skating training to ensure that the training activities are sustainable while reducing the impact on the environment, so as to build a sustainable development of the new ecology of skating sports training.
