In order to prevent the onset of sports injuries in college students and reduce the incidence of sports injuries, the prevention methods of sports injuries among college students were studied through functional movement screening. 160 college students were selected for functional action screening and scoring test. They were tested by scoring. This paper analyzed the overall test results of College Students"functional movement screening, the results of College Students" flexibility screening, the results of stability screening and the results of basic motor function screening, analyzed the correlation of different functional movement screening scores of College students, studied the distribution characteristics of functional movement screening scores of College students, and analyzed of the prevention effect of exercise injury. The results showed that the scores of rotation/rotation stability items were the lowest and the scores of shoulder flexibility were the highest; the range of shoulder motion and hip flexibility of female college students were better than that of male college students, and the trunk stability of male students was better than that of female students; the correlation between total score and flexibility of functional movement screening was the highest, and the correlation between total score and stability was the lowest, but the overall correlation was higher; the distribution of functional movement screening scores was the main. Focus on the middle part; Functional movement screening can reduce the incidence of injury among college students. From the results, we can see that the flexibility and stability of the hip and ankle joints of college students are relatively poor, which requires targeted training.; for flexibility, stability and basic movement problems, it is necessary to carry out corresponding corrective exercises; it is very important to improve the flexibility and stability of college students"bodies; it is necessary to pay attention to the relationship between the flexibility and stability of college students" bodies, to prevent the occurrence of injuries, and to reduce the probability of injuries. Through functional movement screening and injury prevention training, it can effectively prevent college students from injury, enhance the physical fitness of college students and improve their physical function.
