Previous studies on the effect of exercise or physical activity on our health indicate that it helps safeguard our brain cells. A recent study explains how this happens, and, below, we’ll summarize what you need to know about it.

Details of the Study

A study was conducted on 134 participants, with an average age of 69 and no memory problems. It was carried out to learn more about the effects physical activity on brain health, as well as establish an approach for preventing or inhibiting thinking and memory issues as people get older. These participants filled out details about their exercise routines in the least year. The researchers also gathered details about blood pressure, cholesterol, insulin levels, Body Mass Index, and other necessary info. You can access the full study here.

Observations from the Study

The following observations were made once the study was completed:

• The group in the population who engaged more in exercising had about 550,000 cubic millimeters of brain gray matter, while those who exercised less had about 10,000 less
• Similar findings were seen when the study was limited to those brain areas affected by Alzheimer’s disease
• Participants who engaged in more physical activity had higher glucose metabolisms when compared with those who engaged less in physical activities or exercise. The study confirmed that a reduced rate of glucose metabolism is typical in people with dementia
• Engaging in more exercises and physical activities did not affect the amount of amyloid plaque (a known marker for Alzheimer’s disease) in people’s brains

Conclusions from the Study

Several conclusions have been drawn from the study:

• Older adults who exercise and perform more physical activities gain benefits that positively affect their heart and blood vessels and could provide better brain integrity
• Nothing about the study shows that physical activity protects brain volume. All the study does is show an association between the two
• Brain health could be promoted by maintaining a low Body Mass Index using physical activity. This could aid in preventing insulin disturbed metabolism often associated with aging

How Does Exercise Protect the Brain?

The observations and conclusions drawn from the study is that exercise or physical activity could help protect brain cells by lowering the amount of body fat and insulin levels. However, further research is needed to prove whether exercise protects the volume of the brain.
