Exercise may protect brain volume by keeping insulin, BMI levels low: Study

Date:

A new study has found that exercise can help protect brain cells. It has been suggested that the role of exercise in maintaining insulin and body mass index levels may help protect brain volume and thus help ward off dementia.

The study was published in the journal ‘Neurology’.

“These results may help us better understand how physical activity affects brain health, which may guide us in developing strategies to prevent or delay age-related declines in memory and thinking skills.” ,” said study author Geraldine Poisnel, PhD, Inserm. Research Center in Caen, France.

“Older adults who are physically active receive cardiovascular benefits, which may result in greater structural brain integrity,” she said.

In contrast, the researchers found that the association between exercise and glucose metabolism in the brain was not affected by insulin or body mass index (BMI) levels. Decreased glucose metabolism in the brain can be seen in people with dementia.

The study included 134 people with an average age of 69 who had no memory problems. People filled out surveys about their physical activity over the past year. He had a brain scan to measure volume and glucose metabolism. Information was collected on BMI and insulin levels as well as on cholesterol, blood pressure and other factors.

The brains of those with the most physical activity had a greater total amount of gray matter than those with the least physical activity, on average about 550,000 cubic millimeters (mm3) compared to about 540,000 mm3. When the researchers only looked at the areas of the brain affected by Alzheimer’s disease, they found the same results.

Those with the most activity had a higher average rate of glucose metabolism in the brain than those with the lowest activity.

Higher physical activity was not associated with how much amyloid plaque the people had in their brains. Amyloid plaque is a marker for Alzheimer’s disease.

Poisnell said more research is needed to understand the mechanisms behind these relationships.

“Maintaining a low BMI through physical activity can help prevent the disturbed insulin metabolism that is often seen in aging, thus promoting brain health,” Poisnell said.
