Older brains benefit from all types of exercise

At the risk of being repetitious, I have had three family members suffer from Alzheimer’s Disease and/or dementia. At the age of 77 I am really concerned about living a long life, but WITH my brain fully functional. That is only one of the reasons I ride my bike every day here in Chicago. I promote exercise in all its forms here and subscribe to the mantra: eat less; move more; live longer.



Many studies have told us exercise is good for the brain. But does it depend on the type of exercise? New research suggests not – at least for seniors. A study of older people found the brain benefits from many types of physical activities – and you don’t have to go to the gym to do them, according to Medical News Today.

The team, from the Institut universitaire de gériatrie de Montréal, an institution affiliated with the University of Montreal in Canada, reports the findings in the journal AGE.

With his colleagues, lead author and exercise physiologist Dr. Nicolas Berryman examined the effect of different forms of exercise on executive function in older adults.

Executive function is the part of cognition that allow us to respond effectively as our environment changes. For example, we use it to plan, organize, pay attention, remember details and manage time and space.

There was a time when scientists believed only aerobic exercise or “cardio” – for instance running, jogging, swimming and walking – could improve executive function. But Dr. Berryman says more recently scientists have discovered that strength-training also has benefits. And now:

Our new findings suggest that structured activities that aim to improve gross motor skills can also improve executive functions, which decline as we age.”

Forty-seven healthy adults aged 62 to 84 years completed the study in three groups. Each group completed a training program, focusing on different exercise methods. The exercise sessions took place three times a week for 8 weeks.

One group completed a program that focused on high-intensity aerobic exercise, another focused on strength-training, and the third group performed tasks that exercised gross motor activity such as coordination, balance, throwing and catching a ball, locomotive tasks and flexibility.

All participants underwent assessments of physical fitness and cognitive performance before and after their 8-week programs. Physical fitness was assessed using measures of body composition, VO2 max and maximum strength. Cognitive performance was measured with a standard test of executive function known as Random Number Generation.

You do not have to go the gym to do exercise that benefits the brain

The results showed that while physical fitness only improved in the aerobics and strength-training groups, all three groups showed similar improvements in cognitive performance.

Many of the exercises the participants in the third group performed can easily be done at home. The researchers say this is encouraging news for sedentary older people who may be put off exercising just because they are reluctant to go to a gym. They could make a difference by just doing any activity they liked at home.

“I would like seniors to remember that they have the power to improve their physical and cognitive health at any age and that they have many avenues to reach this goal,” Dr. Berryman urges.

Funds from the Canadian Institutes of Health Research helped finance the study.

Medical News Today learned of another study that also reinforces the keep moving message. Researchers from the University of Illinois suggested even if you exercise at the end of the day for half an hour, sitting too much can be bad for the brain.

    • Absolutely. I have an Apple watch that reminds me every hour to stand up. I think there are also other gadget that do this if you aren’t an Apple person (like me!).

    • Thanks for sharing that. Too often, the loved ones of the afflicted are completely overlooked. I Had a terrible time for the entire six years my aunt lived with Alzheimer’s.
