Introduction: We should pay attention to physical and psychological training still in the growth phase of athletes to ensure a better overall performance quality. Psychological training can be an effective tool to improve the technical level and skills of swimming. Objective: This paper discusses the relationship between mental health education and training intensity in college swimmers. Methods: The mental health of professional swimmers in college sports is explored with study subjects undergoing a 10-week training trial. The comparison of clinical effects between various psychological training modalities and swimmers’ self-management is analyzed. In a second step, this paper performs statistics and analysis on the questionnaire and experimental data. Results: The exercise ability of the control group was significantly improved after relaxation training, tension training, and thought control training (P<0.05). The results showed that the learning effect of the experimental group was significantly better than that of the control group (P<0.05). Conclusion: Psychological training and self-regulation in training have a good effect on improving the mental quality of competitive sports players. This approach improves athletes’ performance more effectively than other approaches. The psychological self-regulation training method is one that swimming coaches should pay attention to and advocate vigorously.
