Study finds running can help improve memory

GOING for a run can help you remember and scientists say new information about a key protein may help explain the link between a memory boost and hitting the treadmill.

International researchers have discovered that the protein cathepsin B, which rises during exercise, has beneficial effects on the brains of mice by improving nerve growth and spatial memory.

The researchers also found that people who exercised consistently for four months had increased levels of cathepsin B in their blood and better memory recall.

Senior author Henriette van Praag, a neuroscientist at the National Institute on Aging in the US, said the overall message was that a consistently healthy life-style paid off.

"People often ask us, how long do you have to exercise, how many hours? The study supports that the more substantial changes occur with the maintenance of a long-term exercise regimen," she said.
