title: Influence of personal patterns of behavior on the effects of Tai Chi: a pilot study.
abstract: OBJECTIVE
  To investigate the influence of individual patterns of personality and behavior on the change in mood status after a brief period of Tai Chi exercise.
  
  
  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.
