[Retracted] Experimental Analysis of the Effect of Rehabilitation Intervention on Tennis Players by Joint Injury Treatment

Table 2

Comparison of rehabilitation process.

	Traditional stretching rehabilitation implementation process	Functional extension rehabilitation implementation process
Rehabilitation goals	1. Strengthens the muscular extension of the shoulder complex	Improve the shoulder complex muscle stretching of tennis players, and combine the rehabilitation benefit of functional stretching with tennis specialty
	2. Strengthen the athletes’ consciousness of stretching and rehabilitation to reduce the loss
Rehabilitation task	Cooperate with the tennis project and choose the corresponding stretching rehabilitation action	Combined with the specific movement pattern of tennis, the corresponding functional stretching rehabilitation is designed to improve specific skills
Rehabilitation principle	Increases neuromuscular excitability and the cross-sectional area of muscle fibers. Work the big muscles first and then work the small muscles	Push and pull exercises in the horizontal direction and those in the non-horizontal direction in appropriate proportions. For each set of pushing exercises, there should be at least one set of pulling exercises [25]
