Don’t Blow Off Your Workout: Exercise Keeps Your “Mind Sharp” Over 50

No, exercise doesn’t really help you lose weight, but you should do it anyway.

Exercise

From The BBC:

Doing moderate exercise several times a week is the best way to keep the mind sharp if you’re over 50, research suggests.

Thinking and memory skills were most improved when people exercised the heart and muscles on a regular basis, a review of 39 studies found.

This remained true in those who already showed signs of cognitive decline.

Taking up exercise at any age was worthwhile for the mind and body, the Australian researchers said.…

Physical activity has long been known to reduce the risk of a number of diseases, including type-2 diabetes and some cancers, and it is thought to play a role in warding off the brain’s natural decline as we enter middle age.

The theory is that through exercise the brain receives a greater supply of blood, oxygen and nutrients that boost its health as well as a growth hormone that helps the formation of new neurons and connections.

In this analysis of previous studies, researchers from the University of Canberra looked at the effects of at least four weeks of structured physical exercise on the brain function of adults.

In a variety of brain tests, they found evidence of aerobic exercise improving cognitive abilities, such as thinking, reading, learning and reasoning, while muscle training – for example, using weights – had a significant effect on memory and the brain’s ability to plan and organise, the so-called executive functions.

Joe Northey, study author and researcher from the Research Institute for Sport and Exercise at Canberra, said the findings were convincing enough to enable both types of exercise to be prescribed to improve brain health in the over-50s.

“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,” he said.

He said people should be able to hold a conversation while doing moderate exercise.

NHS guidelines recommend that adults do at least 150 minutes of moderate aerobic activity every week and exercise the major muscles on two or more days a week.

So don’t skip your workout, Peeps, even though over 60 studies strongly suggest it does not help you lose weight (sorry!)

What’s your plan for sticking with your workout? Are you getting at least that 150 minutes of cardio and 2-3 strength workouts a week? Please let me know in the comments.
