Rugby is a highly competitive sport with unique functional demands on the upper limbs, resulting in a high incidence of impact injuries to the rotator cuff and elbow joint. After the repair of such injuries, conventional rehabilitation training often fails to meet the specialized athletic requirements for athletes returning to competition, which can easily lead to secondary injuries or a decline in athletic performance. Based on the specialized mechanisms of upper limb impact injuries in rugby and the core needs after repair, this paper constructs a three-stage specialized adaptive training program: “clinical rehabilitation - specialized transition - competitive adaptation,” along with proposing individualized adjustment strategies and risk prevention measures. The aim is to provide a scientific basis for the Basketball and Rugby Sports Management Center to formulate rehabilitation plans for athletes after injury, enhance rehabilitation efficiency, and ensure the safe return of athletes to competition.
