Influence of Personal Patterns of Behavior on the Effects of Tai Chi
March 28, 2011
Do the individual patterns of personality
and behavior have any influence on the change in mood status after a brief
period of Tai Chi exercise? That is the question several Japanese researchers
Osaka University Graduate School of Medicine wanted to address in their study.
The study used the Type A and Type B
personality theory, which describes two common, contrasting personality
types—the high-strung Type A and the easy-going Type B—as patterns of behavior
that could either raise or lower, respectively, one's chances of developing
coronary heart disease.
Though it has been widely controversial in
the scientific and medical communities since its publication, the theory has
nonetheless persisted, both in the form of pop psychology and in the general
lexicon, as a way to describe one's personality. Such descriptions are still
often equated with coronary heart disease or other health issues, though not
always as a direct result of the theory.
In the Japanese study, 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.
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
These findings suggest that a brief period of Tai Chi exercise
is mentally beneficial, particularly to individuals with type A characteristics.
This study is published in the January 2011 issue of
Environmental Health and Preventive Medicine.
