FMRI activity during associative encoding is correlated with cardiorespiratory fitness and source memory performance in older adults

• Aerobic fitness is positively associated with source memory in older adults (OA).
• Fitness is correlated with fMRI activity during face-name learning among OA.
• Fitness is associated with reductions in age differences in some brain regions.
• In other brain regions, fitness linked to larger age differences in fMRI activation.
• Medial frontal cortex indirectly influenced the link between fitness and memory.
