Physical inactivity has been identified as an important risk factor for dementia. High levels of
cardiorespiratory fitness (CRF) have been shown to reduce the risk of dementia. However …

The human brain undergoes marked structural changes with age including cortical thinning
and reduced connectivity because of the degradation of myelin. Although these changes …

Aging is associated with reductions in gray matter volume and cortical thickness. One factor
that may play a role in mitigating age-associated brain decline is cardiorespiratory fitness …

Previous work has confirmed the benefits of aerobic exercise for brain aging, however
mechanisms underlying these effects remain unclear. Two measures of exercise, time spent …

Cortical atrophy is a biomarker of Alzheimer's disease (AD) that correlates with clinical
symptoms. This study examined changes in cortical thickness from before to after an …

Purpose The aim was to examine the effect of a 5-year exercise intervention at different
intensities on brain structure in older adults from the general population partaking in the …

Studies have shown that aerobic exercise has the potential to improve cognition and reduce
brain atrophy in older adults. However, the literature is equivocal with regards to the …

Background: high cardiorespiratory fitness (CRF) is associated with larger brain volumes but
data on sex differences in the association of CRF with brain volumes are scarce. We …

Fractal dimensionality (FD) measures the complexity within the folds and ridges of cortical
and subcortical structures. We tested the degree that FD might provide a new perspective on …
