Just a day after my post – Vigorous exercise may restore mental health, Tufts Health & Nutrition Update comes along with the query – Are you keeping your brain in shape?
“Physical activity helps preserve mobility and motor skills as you age – and not just by keeping your muscles in shape. A new study suggests that activity also maintains mobility by protecting your brain. Even in people with signs of brain aging called white matter hyperintensities (WMH) associated with movement issues, being more active seemed to allow the brain to compensate.
“Tammy Scott, PhD, a scientist at Tufts’ HNRCA Neuroscience and Aging Laboratory, says of the findings, “Although the study cannot determine causality because of its cross-sectional design, their results are consistent with a number of other studies that have shown that increased physical activity protects mobility.”
BRAIN SPOTS AND MOBILITY:
“The study, published in the journal Neurology, subjected 167 people without dementia, ages 60 to 96, to a battery of tests. They had MRI scans of their brains, wore activity monitors for up to 11 full days, and underwent 11 motor-performance tests, such as grip strength, finger tapping and lower-body function.
