This paper explored the effects of practicing Qigong, a traditional Chinese fitness method which includes the imitation of the Five- animal exercise, on the psychological adjustment of college students with different personality types. Through the study of 220 college students aging from 19 to 22 a study of the responses made on the Eysenck Personality Questionnaire (EPQ) and Symptom check list-90 (SCL-90)] provided scientific data that supported the idea that Chinese traditional health preservation exercises can improve the mental health of college students. Specifically, after 12-week Qigong exercise, the total symptom index, interpersonal sensibility, obsessive-compulsive, paranoid-anxiety, depression, psychoticism and anger-hostility of the participants significantly differed from baseline. There were also significant differences in somatization and anxiety. In the female participants in the experimental group, there was a very significant difference in terms of anger-hostility, and there were also significant differences in terms of paranoid-anxiety and psychoticism, and in somatization, depression and the total symptom index. Further improvements are described.
