Research shows that aging is more than just the number of years lived; it encompasses how organs and cells cope with those years. Different body parts age at varied rates, which is also true for the brain. A study following over 900 participants for over 40 years revealed a correlation between walking speed at age 45 and brain aging markers. Slow walkers exhibited reduced brain volume, more white matter lesions, and cortical thinning, indicating a faster biological aging process and greater cognitive decline over time. Participation in a year-long walking trial increased hippocampal volume by 2 percent compared to a control group, highlighting the importance of regular walking for brain health.
Walking speed at age 45 has been linked to significant brain aging markers, with slower walkers experiencing greater cognitive decline and reduced brain volume over time.
A recent walking trial demonstrated that a year of increased walking yielded a 2 percent increase in hippocampal volume, emphasizing the impact of physical activity on brain health.
