The subjects of this study include 25 old Yuan-Ji Dance participants, with an average age of 68.5+2.8, and 18 sedentary controls, aged 69.7+3.7 years. All the Yuan-Ji participants have learned the ten sets of Yuan-Ji acts and are divided into three span groups: 3-5 years (n=6), 5-8 years (n=9) and over 8 years (n=10). Physical performance is assessed using (1) static balance: one-leg stance with eye open for 30 seconds on Catsys 2000 force platform on flat ground, (2) dynamic balance: both-feet stance with eye open for 30 seconds on Catsys 2000 force platform placed on Reebok Dynamic platform and (3) lower-extremity strength: 30-second chair stand test. The data for comparison between the Yuan-Ji group and the sedentary controls are analyzed with t-test, with a=.05, while the data for comparison among three Yuan-Ji dance spans are analyzed with one-way ANOVA, with p<.05. The results of this study show that the Yuan-Ji group performs significantly better than the sedentary group both in balance control ability and in lower-extremity strength. Specifically, in the non-dominant-leg stance test, the Yuan-Ji group has all the balance functions significantly better than the sedentary group, which is proposed to have a close connection with the time frame of lower-limb movements in Yuan-Ji Dance. Besides, in static as well as dynamic balance, the significance is mainly found in the function of sway area, which is suggested to be in connection with the spatial features of the Yuan-Ji movements. Among the three Yuan-Ji dance span groups, the group of the longest span has lower-extremity strength significantly better than the other two groups, but in balance control ability, the three groups show no significant difference. It is concluded that participating in Yuan-Ji Dance regularly and continuously (over 3 years) helps the old people to maintain their performance of balance and lower-extremity strength. Key words: Yuan-Ji Dance, balance, lower-extremity strength
