Why exercise helps memory

29 Jun

A paper in the journal Cell Metabolism offers another explanation for the postive effect of exercise on memory:

“Here, we show that a muscle secretory factor, cathepsin B (CTSB) protein, is important for the cognitive and neurogenic benefits of running.”

Here is a journalistic summary:

“Working out is good for the brain. Now, a team of scientists from the U.S. and Germany has a clearer idea why. A protein called cathepsin B, produced and secreted by muscle during exercise, is required for exercise-induced memory improvement and brain cell production in mice, the scientists reported in Cell Metabolism today (June 23). They also showed that levels of cathepsin B are positively correlated with fitness and memory in humans”
