[Purpose] The purpose of this study was to examine the relationship between grip strength and foot-gripping strength with motor functions among young-old and oldold participants. [Method] In total, 312 elderly women (age: 73.0 ± 6.1 years) participated in this study. They were classified into two groups of the young-old (age: 65-74 years) and the old-old (>75 years). To evaluate physical function, grip strength, foot-gripping strength,and a 5-meter maximum-walking time (5 MWT) were measured, and a 30-second chairstand test (CS-30) and a timed up-and-go test (TUG) were conducted. We used the t-test to compare the two groups. Multiple regression analyses were performed to determine the relationship between strength (grip and foot-gripping) and motor functions. [Results] Among the young-old, all motor functions were a significant and independent factor of foot -gripping strength. However, all motor functions were a significant and independent factor of grip strength among the old-old. [Conclusions] We show that foot-gripping strength is a useful measurement of motor function among the young-old, whereas grip strength is a useful measurement among the old-old.
