These common exercises may protect against cognitive decline

In a recent study published in Mayo Clinic Proceedings, researchers found that cardiorespiratory exercise — walking briskly, running, biking and just about any other exercise that gets your heart pumping — is good for brain health.

They found a link between cardiorespiratory fitness and brain health, particularly in gray matter and total brain volume — regions of the brain involved with cognitive decline and aging.

The study is from the German Center for Neurodegenerative Diseases. One author is Katharina Wittfeld, Ph.D.

Brain tissue is made up of gray matter, or cell bodies, and filaments, called white matter, that extend from the cells.

The volume of gray matter appears to correlate with various skills and cognitive abilities.

In the study, the team examined 2,013 adults from two independent cohorts in northeastern Germany. Participants were examined in phases from 1997 through 2012.

Cardiorespiratory fitness was measured using peak oxygen uptake and other standards while participants used an exercise bike. MRI brain data also were analyzed.

The researchers found that increases in peak oxygen uptake were strongly linked to increased gray matter volume.

The higher gray matter volume linked to cardiorespiratory exercise is in brain regions clinically relevant for cognitive changes in aging, including some involved in Alzheimer’s disease.

This provides indirect evidence that aerobic exercise can have a positive impact on cognitive function in addition to physical conditioning.

The results suggest cardiorespiratory exercise may contribute to improved brain health and decelerate a decline in gray matter.

Good cardiorespiratory fitness also involves not smoking, following healthy eating habits, losing weight or maintaining a healthy weight level, managing blood pressure and avoiding hypertension, controlling cholesterol levels, and reducing blood sugar, which over time can damage the heart and other organs.

If you care about exercise, please read studies about exercises in the morning and evening offer different health benefits and findings of just 1 hour of this exercise every week may prevent heart attack, stroke.
