German Study Links 4,188 Adults' Movement to Healthier White Matter, Strongest in Least Active

Summary
4,188 adults in Germany who wore activity trackers and underwent brain scans showed a clear link between more daily movement and healthier white matter, especially among the least active people.
Moderate-to-vigorous activity—such as brisk walking, cycling or stairs—showed the strongest association, while light activity was weaker and more sitting tracked with poorer white-matter measures.
Older adults showed healthier long-distance brain connections when they moved more, suggesting the apparent benefit may grow with age in regions vulnerable to age-related decline.
Body weight and inflammation appeared to explain part of the relationship, but the cross-sectional study cannot prove movement caused better brain wiring or rule out that healthier brains support more activity.
Participants averaged about 8,800 steps a day yet still spent roughly three-quarters of tracked hours sitting or lying down, underscoring how reducing sedentary time may matter alongside exercise.
