Association between physical activity and handgrip strength among older adults in the Korean longitudinal study of ageing.

ABSTRACT: Population ageing is progressing rapidly worldwide, with Korea experiencing one of the fastest rates. Handgrip strength is used as a marker for physical capability and has potential as a biomarker of vitality. Among various influencing factors such as socioeconomic status, health behaviors, and genetics, physical activity stands out as a key modifiable lifestyle factor that may help preserve muscle strength in older adults. However, most prior studies have employed cross-sectional designs, which provide only a limited snapshot of this relationship.

To examine the longitudinal effect of ph
