At the time of the corona disease, the fear of the disease along with the confusion of daily activities, it can be important to pay attention to the defense styles in dealing with the corona anxiety. Participating in physical and sports activities is one of the defense styles that can play an effective role in reducing anxiety and cognitive impairment caused by Corona and strengthening the body's immunity. In this regard, the aim of this study was to investigate the effectiveness of cognitive-motor exercises of tai chi on executive functions and corona anxiety. For this purpose, a number of 40 people with an average age of 63.42 ± 1.40 were selected from Tehran, and after performing the pre-test of executive functions (components of working memory and selective attention) and the Corona anxiety scale, they were randomly divided into two experimental and control groups. Then the experimental group participated in the tai chi training program online for 8 weeks and the control group did their daily activities. Finally, the post-test was performed and the results were recorded. Data analysis was done with the statistical method of univariate covariance and multivariate two-way analysis of variance in SPSS software version 26. The results of the multivariate variance test showed that the effect of Tai Chi cognitive-motor exercises on working memory and selective attention is significant. Comparing the groups, the results showed that the participants of the experimental group performed better than the control group (P=0.001). In addition, the results of the covariance test showed that Tai Chi exercises led to the reduction of corona anxiety in the participants of the experimental group. According to the findings, it seems that the use of tai chi cognitive-motor intervention is a useful method to increase cognitive performance and reduce anxiety caused by corona in elderly women.
