If you read through the research, it comes up over and over again. It’s good for our hearts. It helps moods. It keeps our bones strong. It keeps our weight stable. It even makes our brains bigger.
Here is more evidence to suggest it also makes our memory better.
In this study, they took women between 70-80 years old, all of whom were complaining of memory problems, or as the researchers referred to it, Mild Cognitive Impairment (MCI).
These women were divided into three groups. One did aerobic exercise, one did strength training and a third was a control group. The treatment groups engaged in activity twice a week for 60 minutes.
Compared to controls the treatment groups both had improved verbal and spatial memory, with the best gains being in the group who did the aerobic activity.
The findings make sense. Move the body, move the blood, get more oxygen to the brain, as well as more fuel and nutrients for the old thinker to work.
But this might be the most important takeaway: “aerobic activity” wasn’t intensive marathon training. It was a 60-minute walk outside at 60% of max heart rate TWICE a WEEK. That’s basically a brisk-ish walk.
The average Canadian spends dozens of hours a week in front of conventional TV and the web combined, consuming media of one type or another. Converting just TWO of those to walking seems like an achievable goal.
