By measuring the brain waves of state-trait anxiety sufferers before and after doing Taijiquan exercise,and by employing psychological test questionnaire STAI(State-Trait Anxiety Inventory),the authors explained and expatiated on the changes of psychology of anxiety of state-trait anxiety sufferers before and after doing Taijiquan exercise,and revealed that the testees in both groups showed a significantly lowered level of state-trait anxiety (P0.01) when finishing Taijiquan exercise and recovering,and that the patterns of changes in both groups are different(P0.01),which indicates that the brain wave rhythms are significantly different after the testees had done Taijiquan exercise.The authors compared the correlativity between brain wave and state-trait anxiety,and revealed the following findings: The α_1,α_2 and β_1 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 β_1 wave showed a very obvious negative correlation;yet the β_2 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 α_1,α_2 and β_1 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.
