Aerobic fitness and intraindividual reaction time variability in middle and old age

Abstract:

Objective: To examine whether aerobic fitness moderated age differences in within-person reaction time variability (WP RT variability) and given conceptual linkage involving the frontal cortex, whether effects were mediated by executive function. Method: Aerobic fitness (estimated VO 2max ) and WP RT variability were investigated in 225 healthy, community-dwelling adults aged 50–90 years ( M = 63.83) across 4 cognitive domains; psychomotor performance, executive function, visual search, and r...
