Brain Resting-state Functional Connectivity Mediates the Age-associated Decline in Physical Activity Engagement.

ABSTRACT:

Background

Physical activity (PA) engagement declines with age in late adulthood. Therefore, understanding factors underlying PA engagement is needed for PA promotion in older adults. Executive function is a potential key neurocognitive resource that supports PA engagement. The current study aims to provide neurobiological evidence for this hypothesis by examining the role of the executive function networks in PA engagement.

Methods

Resting-state functional magnetic resonance imaging data and self-reported PA engagement were obtained from the Cambridge Centre for Ageing and Neuroscience (Cam-CAN; age range 18-81). The frontoparietal network and salience network were chosen as networks of interest.

Results

We found that PA engagement began to decline at the age of 49 v
