Introduction: Injuries will always be with an athlete throughout their career. When analyzing the factors that cause athletic injuries, their coaches usually consider environmental and physical training factors, ignoring psychological factors. Objective: Investigate the mental health status of college athletes after serious injuries during competition, discussing the impact of sports injuries on athletes' mental health. Methods: Twelve college athletes were selected as research volunteers. They were divided into two groups by randomization. The control group was followed by traditional psychotherapy while the experimental group received the post-traumatic mental intervention. A comparison was carried out and mainly the general situation of sports injuries and the effect of intervention treatment were analyzed. The impact of psychological intervention methods on athletes' mental health after injuries were also studied using mathematical statistics to analyze the data. Results: There were significant differences in STAI scores in the experimental group before and after the intervention. BFS scores in the experimental group were significantly higher than those in the control group before and after an intervention. There was no significant difference in the indicators in the control group. Conclusion: Post-traumatic psychological intervention positively affects the mental health recovery of college athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
