Exercise in middle age prevents stroke in old age
People who exercise regularly from the age of 40 are less likely to suffer brain damage and shrinkage of the vascular network at the age of 70 and older.
Washington – A recent American study reported that regular exercise in middle age reduces the chances of stroke in old age.
The study was conducted by researchers at the University of North Carolina, and its results were published Sunday in the Journal of the American Heart Association.
The research team conducted its study on a group of mice, to reveal the relationship between regular exercise and stroke prevention.
The researchers found that mice that began exercising regularly at 12 months of age (the equivalent of 40 years in humans) were less likely to suffer brain damage and shrinkage of the vascular network when they reached the age of 25 months (the equivalent of 70 years in humans).
“The results of the study suggest that regular exercise can reduce the chances of stroke,” said Dr. James E. Faber, lead researcher at the University of North Carolina.
A stroke is due to a severe disruption in the blood supply to the brain, due to a sudden rupture or blockage of a blood vessel in the brain.
There are distinctive symptoms of a stroke, on top of which is the emergence of sudden language disturbances such as slurred speech or switching of its syllables, as well as difficulty in understanding others, sudden paralysis or a feeling of paresthesia, dizziness accompanied by instability while walking, visual disturbances, and severe headaches.
According to the US Centers for Disease Control and Prevention (CDC), stroke is one of the leading causes of disability and death in America, affecting more than 795,000 and killing 130,000 Americans annually.
The World Health Organization advises children and young people to exercise for at least an hour a day, in addition to allocating the bulk of daily physical activity to outdoor games.
The organization added that practicing physical activity helps young people to grow bones, muscles, joints, heart and lungs in a healthy way, in addition to maintaining an ideal body weight.
