Characteristics of physical function and body composition among community-dwelling older females with and without locomotive syndrome

[Purpose] This study aimed to clarify the presence or absence of locomotive syndrome as determined by two-step and stand-up tests, which measure physical ability as well as the characteristics of physical function and body composition among community-dwelling older females. [Participants and Methods] The study included 36 community-dwelling older females (aged 75.3 ± 6.0 years), who were classified into two groups: those with and without locomotive syndrome following the locomotive syndrome criteria. Their physical function and body composition were evaluated and compared. [Results] No significant differences in body composition were observed between participants with and without locomotive syndrome, as defined by the locomotive syndrome criteria. However, significant differences were noted in grip strength on the left side and open-eyed one-legged standing, 5-m comfortable walking speed and the timed up-and-go test on both the right and left sides. [Conclusion] The results indicate that physical function is a valuable criterion for evaluating the older populations. However, components of body composition that reflect physical condition and function require validation.
