Abstract

Age-related mobility and cognitive declines are closely linked, but their relationship is complex and needs to be further investigated. The study aimed to test if cognition (processing speed, inhibition and switching performances) mediate the age-related difference in mobility. Mediation analyses were used to test whether processing speed, inhibition and switching performances on the Stroop test mediate the relationship between age and performances at the Timed Up and Go (TUG). Only switching performances mediated the age-related difference in TUG (65.1% of the total effect) supporting the notion that executive control plays a critical role in older adults' mobility.
