The purpose of this study is to examine which physical factors have the deep relationship with the dynamic balance function for elderly people. The subjects of this study were 50 healthy elderly people (24 males, 26 females, and the average age was 71.2± 5.5 years old). Measurements were Functional Reach Test (FRT) which is the index of dynamic balance function, one foot standing with eyes open, closed which are the indexes of static balance function, grip strength and the 30-sec chair stand test (CS-30 test) which are the indexes of muscular strength, chair sit-and-reach test which is the index of suppleness, stick reaction which is the index of agility, 10 m maximum walking speed and timed up and go test (TUGT) which are the indexes of walking ability. As a result, the significant correlativity between FRT and CS-30 test, one foot standing with eyes open and closed, TUGT, 10m maximum walking speed were showed. Especially, it showed high correlativity between FRT and 10 m maximum walking speed, TUGT, CS-30 test, which suggests muscular strength of lower limbs and walking ability were important as factors to affect dynamic balance function.
