Do you want to keep your mind sharp as you age? Well it’s not difficult to stack the deck in your favor. Studies (1,2,3) prove that adopting a lifestyle that includes exercises such as walking, cycling or jogging on a regular basis helps boost brain power. The fact is, exercise actually stimulates new brain cell production (4), so keep your mind sharp with exercise!
A recent study in the British Journal of Sports Medicine (5) confirmed that moderate exercise such as going for a walk several times a week is the best way for people over 50 to maintain their cognitive ability and physical health. The study analyzed 39 studies that confirm that thinking and memory skills are improved with regular exercise of the heart and muscles. It’s important to note that these cognitive improvements are also seen in older individuals with existing symptoms of cognitive decline, so it’s clear that exercising is worthwhile at any age.
The research shows that aerobic exercise appears to improve and cognitive function and resistance training can enhance a person’s executive function and memory. So what’s the bottom line? Try to get aerobic or resistance exercise of at least moderate intensity on as many days of the week as possible (6).
Look at it this way: it’s easy. According to Nielsen, “people over the age of 50 watch the most TV, somewhere in the range of 50 hours a week” (7). If this sounds like you, how about trading time spent watching TV for time spent going for a walk? An astonishing 80% of adults don’t get the recommended 150 minutes of exercise per week (8).
So ask yourself: what are your priorities? How hard is it to get out and go for a walk or a bike ride for 30 minutes, 5 times per week? Is it worth it to you to prevent the possibility of cognitive decline? And think about it: there are so many possibilities.

Exercising is good for you no matter what your age, and it’s easy to start doing something.
We’ve known for many years that physical activity reduces the risk of a many diseases, including type-2 diabetes, osteoporosis, Alzheimer’s and some cancers. Now we know that physical activity also helps slow or even reverse the brain’s natural decline that occurs as we age.
Researchers believe that exercise increases the supply of blood, oxygen, nutrients and also a growth hormone that promotes the formation of new neurons and connections to the brain.
Aerobic exercise is positively related to improved cognitive abilities, such as thinking, reading, learning and reasoning, while resistance training such as working out with weights significantly effects the memory and executive functions, such as the ability to plan and organize.
“Even if you are doing moderate exercise only once or twice a week there are still improvements in cognitive function, but the improvements were better the more exercise was done,” said Joe Northey, the study author from the Research Institute for Sport and Exercise in Canberra, Australia. He went on to say that the study findings are convincing enough that clinicians should now prescribe both aerobic and resistance exercise to improve brain health in people over 50.

In the USA, the National Institute of Health (NIH) and the American College of Sports Medicine (ASCM) recommend that adults get at least 150 minutes of moderate physical activity every week (9, 10). The ASCM also recommends resistance exercises for major muscle groups at least 2 days per week for older adults (11).
In addition to adopting a lifestyle that includes regular physical activity, it’s important to look after our brains by staying mentally active, eating a balanced diet consisting primarily of fresh, whole foods, mostly fruits and vegetables, drinking only in moderation and not smoking.
