Abstract

The purpose of this study is to investigate the effects of a ballet exercise program on depression scale(CES-D), elderly fitness(SFT), and natural killer(NK) cell activity in elderly women. Twenty elderly women subjects aged 65 to 75 years were randomly assigned 10 each to the exercise group(EG) and a control group(CG). The ballet exercise program was 50 minutes and performed 3 times a week for 12-weeks. As a result, CES-D showed an interaction effect between time and group, and it was significantly decreased in the EG, and significantly increased in the CG, and there was a significant difference in the post-test between groups. SFT showed an interactrion effect between time and group in all variables, and all of them were significantly increased in the EG, and there was a significant difference in the change values between groups. NK-cell activity showed an interaction effect between time and group, and it was significantly increased in the EG, and there was a significant difference in the change values between groups. TTherefore, the ballet exercise program of this study had a positive effect on improving depression symptoms, physical strength, and NK-cell activity in elderly women, and is expected to be used as an effective exercise intervention for their physical and mental health.
