A Meta-Analysis of the Effects of Dance Programs on Physical Performance: Appropriate Health Promotion for Healthy Older Adults

다국어 초록 (Multilingual Abstract)

Background: Dancing is a type of physical activity that has been associated with physical benefits in older adults. Regular dancing can help maintain physical function and improve the quality of life in this population. This review evaluated randomized control trials (RCTs) of the effectiveness of dance programs on the physical function of healthy older adults. Methods: We systematically searched four databases (PubMed, Google Scholar, Embase, and ThaiLis) through December 2021 for primary studies evaluating dance programs in healthy older adults aged 60 years and over. The meta-analysis used a random-effects model to compute the effect sizes using a forest plot and Cochran’s Q and I2 statistics as heterogeneity measures. Results: Eight types of dance programs showed significantly improved physical function. Muscle strength was assessed using the five times sit-to-stand test (I2=89%; p=0.003), chair-sit-to-stand-30S test (I2=75%; p=0.006), and 30-s arm curl test (I2=22%; p=0.260). Static balance was evaluated using the Berg-balance scales test (I2=0%; p=0.620) and the one-leg-stand test (I2=32%; p=0.220). Dynamic balance was tested based on the time up-and-go and eight-foot up-and-go tests (I2=51%; p=0.110). Flexibility was assessed based on the back-scratch (I2=56%; p=0.130) and sit-and-reach test (I2=0%; p=0.930). Conclusion: Dance exercise programs improved muscle strength, balance, and flexibility. Such programs are effective and safe for healthy older adults for use as daily exercise to promote health. Therefore, researchers, healthcare providers, and policymakers should establish properly organized dance interventions to improve physical function in healthy older adults.
