Abstract: The “Rehabilitation-Performance Training Integration” training philosophy is a natural outcome of the continuous development in competitive sports and sports science. This philosophy breaks down disciplinary barriers and is centered around functionality, fostering effective communication and collaboration between performance training trainers and sports rehabilitation professionals. The ultimate objective is to expedite athletes' injury recovery, enhance their performance training levels, and facilitate their safe return to the field of competition. From a performance training standpoint, the “Rehabilitation-Performance Training Integration” training philosophy expands the scope of work for performance training trainers. It incorporates functional training as a vital component of performance training training, utilizing functional training techniques to alleviate chronic pain, improve functional impairments, and enhance the quality of functional movement patterns for athletes. This approach thus overcomes the challenge faced by sports teams when addressing common functional issues. The application potential of the “RehabilitationPerformance Training Integration” training philosophy in competitive sports is extensive, garnering significant attention from scholars both domestically and internationally. Further in-depth research and practical implementation of this philosophy is foreseeable. Against the backdrop of vigorous promotion of “proactive health” in the country, the introduction of the “RehabilitationPerformance Training Integration” training philosophy holds tremendous potential in alleviating medical burden and improving public health. Furthermore, it will serve as a critical pathway for the implementation of the national “sports-medicine fusion”strategy. However, the development of suitable training programs for diverse groups necessitates in-depth interdisciplinary research involving experts from various relevant fields, including performance training.
