Digital sports are profoundly reshaping the research paradigms and application paths of sports biomechanics. This article systematically explores how digital technologies such as wearable sensing, motion capture, artificial intelligence and virtual reality can empower sports biomechanics, breaking through the limitations of traditional laboratories in terms of time and space, cost and ecological validity. The article focuses on elaborating its innovative applications in areas such as refined analysis of sports technology, precise monitoring of internal and external loads, active early warning and rehabilitation assessment of sports injuries, generation of personalized training plans, and real-time biofeedback. It also points out that VR/AR technology has opened up a new dimension for immersive training. Meanwhile, the paper also examines the current challenges, including issues such as data accuracy, the lack of multi-source fusion standards, privacy ethics risks, and uneven technology popularization. Research shows that the deep integration of digital sports and sports biomechanics not only significantly enhances competitive performance and scientific training levels, but also provides strong support for public health promotion and sports injury prevention and control. In the future, it is necessary to strengthen technical standardization, cross-disciplinary collaboration and ethical norms construction to achieve sustainable and high-quality development.
