Abstract: The high-quality advancement in digital-empowered mass fitness through digitization and information technology in the context of accelerating the building of a sports power is of utmost significance in addressing the shortcomings in nationwide fitness and achieving a distinctly China's approach to sports modernization. Digital empowerment for high-quality development of mass fitness conforms to the demands of high-quality progress in this era, upholds the values of high-quality fitness supply and overall governance, focuses on fostering coordinated and equitable fitness services in urban and rural areas, explores the path of digital fitness development and sports modernization, and ultimately aims to the efficient fusion between intelligence and governance of mass fitness, balanced growth in both quality and quantity, and precise alignment of supply and demand. Nevertheless, several challenges arise in the high-quality progress of digital empowerment of mass fitness, including the departmentalism formed by traditional sports administration, imbalances in the digital ecosystem leading to systemic disruptions, a digital divide arising from limited digital literacy, and risks resulting from insufficient digital oversight. Based on digital empowerment, from the establishment of a people-centered digital fitness service supply concept, create a digital fitness service community with multiple co-governance as the core, create a digital fitness service inclusive body with public participation as the focus, and form a digital fitness service regulatory body with open and sharing as the core, the realization of the way to promote the high-quality development of national fitness is proposed.
