We know that movement can change your skeletal muscle mass… but what about the idea that movement can change the mass of your brain??? I’m thinking sitting, being inside all day, and being on a computer/screen IS NOT A GOOD IDEA!!! Get off your computer, phone or whatever… and go for a walk!!!!!
UCLA researchers recruited 35 people ages 45 to 75 and asked about their physical activity levels and the average number of hours per day they spent sitting over the previous week. Each person had a high-resolution MRI scan, which provides a detailed look at the medial temporal lobe, or MTL, a brain region involved in the formation of new memories.
The researchers found that sedentary behavior is a significant predictor of thinning of the MTL and that physical activity, even at high levels, is insufficient to offset the harmful effects of sitting for extended periods… click if you want to read about this study done at UCLA.
