Effectiveness of the Osaka “Ten-Year Rejuvenation” Project

Introduction: The “Ten-year rejuvenation project” is an initiative of the Osaka Prefectural Government to reduce the physical and mental age of residents in the prefecture by ten years and enable them to live in good health and vitality in preparation for the Expo 2025 Osaka, Kansai, Japan. Our team tested a “Ten-year rejuvenation dance” for elderly people with the goal of enhancing participants’ muscle strength and physical fitness and improving their cognitive function through memorizing the dance choreography. Method: Groups of around 30 participants each were recruited at 12 locations in Osaka prefecture and the Ten-year rejuvenation dance was practiced once per week over two months. Physical and mental tests carried out before and after participation were compared. Videos were also distributed so participants could dance at home in their free time. The dance program combines elements from physical therapy to improve joint flexibility, balance, muscle strength, and agility. Results: Physical fitness and cognitive scores were both significantly increased and physical tests showed that physical age was reduced by five to ten years. These results confirmed the meaningfulness of continuing this activity. Conclusion: Continued dancing demonstrated positive effects on mind and body, so we plan to increase video distribution to elderly people who cannot leave the house, expand the implementation area, and continue verification in the future.
