Exercise is well-known for its health benefits – but a recent study has found it’s even more beneficial than previously thought.
The study, led by psychologists at Pitt, analyzed data from dozens of previous studies and found that older people may be able to prevent memory loss by exercising regularly.
“Everyone always asks, ‘How much should I be exercising? What’s the bare minimum to see improvement?’” said lead author Sarah Aghjayan, a clinical and biological health psychology PhD student in the Kenneth P. Dietrich School of Arts and Sciences.
“From our study, it seems like exercising about three times a week for at least four months is how much you need to reap the benefits in episodic memory.”
Studies in mice have also found an association between cardiovascular exercise and improved memory, but the results of human studies on the same subject have been equivocal.

Interestingly, the team found there were greater improvements in memory among those who were aged 55 to 68 years compared to those who are 69 to 85 years old — so intervening earlier through exercising is better.
The team found the greatest effects of exercise in those who hadn’t yet experienced any cognitive decline, and in studies where participants exercised consistently several times a week.
“You just need a good pair of walking shoes, and you can get out there and move your body,” added Sarah.
There are many charities across the US that help older people maintain fitness and exercise for their health.
