Abstract

Abstract:

BACKGROUND: There are few reports about the effects of Tai Chi Chuan on perimenopausal syndrome and bone mineral density.

OBJECTIVE: To investigate the effects of regular Tai Chi Chuan exercise on symptoms, plasma dopamine, plasma beta-endorphin and bone mineral density in perimenopausal women.

METHODS: The study was in accordance with the ethical requirements of Southwest University of Science and Technology, and all participants signed the informed consents. Totally 74 perimenopausal women aged 45-55 years were randomly divided into two groups: Tai Chi group (n=36) and control group (n=38). Taichi group took Tai Chi Chuan for 48 weeks (thrice a week, 60 minutes/times). The control group went on previous habits only. The scores of Kupperman scale, dopamine, beta-endorphin, and bone mineral density of lumbar spine and proximal femur were measured before and after 48 weeks.

RESULTS AND CONCLUSION: (1) After 48 weeks, the total scores of hot flashes, sweating, dysesthesia, insomnia, restlessness, vertigo, depression, fatigue, muscular and articular pain and Kupperman scale cores in the Tai Chi group were decreased significantly (P < 0.01), and were significantly lower than those in the control group (P < 0.01). The concentrations of dopamine and beta-endorphin were increased significantly (P < 0.01). There were no significant changes in bone mineral density of L₂_-4, femoral neck, trochanter and Ward’s triangle (P > 0.05). (2) Dopamine concentration was negatively correlated with insomnia, depression and Kupperman total score (P < 0.05), while beta-endorphin concentration was negatively correlated with insomnia, anxiety and Kupperman total score (P < 0.05). (3) In summary, 48-week Tai Chi Chuan exercise can significantly improve the symptoms of perimenopausal women, suggesting that the changes of plasma dopamine and beta-endorphin levels are one of the factors to alleviate the symptoms of perimenopause. However, there is no significant effect on bone mineral density of lumbar spine and proximal femur.

Key words: Tai Chi Chuan, perimenopause, plasma dopamine, plasma beta-endorphin, bone mineral density
