Purpose: The purpose of this study was to investigate the effect of long-term dance sports activity on ego-resilience, subjective happiness and balance in elderly women. The subjects were a total of 40 women who attended in a silver school in a medium-sized city. They all were over 64 years old and have not done exercise for past 6 months. Methods: Subjects were randomly assigned to experimental group (n=20) or control group (n=20). The dance sports activity of the experimental group was consist of ‘cha-cha’ and ‘jive’, and was done for 12 weeks, 3 times per week, 90 minutes per day. Analysis of covariance (ANCOVA) using the pre-test data as covariate was used to compare the difference between the two groups (α=.05). Results: There were significant differences in the ego-resilience [F(1,37)=726.108, p=.000, η2=.952], the subjective happiness [F(1,37)=299.353, p=.000, η2=.895], and the balance[F(1,37)=32.167, p=.000, η2=.738]. Conclusion: It was concluded that long-term dance sports activity have very positive effect on psychological health and balance for elderly women considering each effect sizes η2. Future studies are needed to examine the psychological effect of diverse dance sports programs which are proper for older adult’s physical features.
