METHODS: The mood status in 22 healthy females was evaluated before and after a period of Tai Chi exercise using the Profile of Mood States (POMS) score. Patterns of personal behavior were also assessed by written questionnaire. RESULTS: In the type A behavior pattern group, the score for total mood disturbance decreased significantly after a brief period (20 min) of Tai Chi exercise. No change was observed in the type B behavior pattern group. CONCLUSIONS: These findings suggest that a brief period of Tai Chi exercise is mentally beneficial, particularly to individuals with type A characteristics. PMID: 21432218
