The authors compared the correlativity between brain wave and state-trait anxiety,and revealed the following findings: The α1,α2 and β1 rhythms of brain waves of the testees in the high anxiety group showed a degree different negative correlation with state-trait anxiety under the two conditions,especially,the β1 wave showed a very obvious negative correlation;yet the β2 rhythm showed a medium degree positive correlation with state-trait anxiety when the exercise was finished,but a relatively low degree correlation was shown in the low anxiety group. Hence,the following conclusions are drawn: When finishing Taijiquan exercise and recovering,the testees in the high anxiety group were,with the increment of the α1,α2 and β1 rhythms,in a moderately vigilant state,mood calmed,physically and mentally relaxed,attention focused,and turned into the low anxiety state; the level of anxiety of the testees in the low anxiety group,who were originally in the state of a relatively low level of anxiety,was almost lowered to the lowest level via Taijiquan exercise,and was not prone to being affected by factors such as external condition and stress.
