A new study shows that age-related differences in brain health—specifically the strength of connections between different regions of the brain—vary with fitness level in older adults. The findings suggest that greater cardiorespiratory fitness—a measure of aerobic endurance—relates to stronger brain connections and likely improves long-term brain function in aging populations.
The study results are reported in the journal NeuroImage.
Michelle Voss led the study while a postdoctoral researcher at the University of Illinois with Beckman Institute director Arthur Kramer and kinesiology and community health professor Edward McAuley. Voss now is an assistant professor at the University of Iowa.
