Exercise has been proven to enhance brain health in older adults by preserving brain tissue and improving blood flow


Research has shown that exercise can slow the aging process for older adults such as improving blood flow and preserving brain tissue. Scientific studies show that exercise can significantly improve brain health in older adults as the cognitive function declines as part of the natural aging process.

As adults age, they are more prone to cognitive memory loss diseases, such as Alzheimer's disease, and exercise can prevent deterioration of the region of the brain responsible for memory called the hippocampus.

Older adults are also subject to deterioration of brain tissue and exercise has been shown to preserve this brain tissue more in older adults who regularly exercise, as opposed to older adults who do not exercise at all.  Exercise has been proven to be beneficial for both cardiovascular health and cognitive health as well as preventing risks for several diseases and illnesses.

Older adult athletes showed a decrease in blood flow near regions of the brain that control memory

A study led by Dr. J. Carson Smith and researchers at the University of Maryland's School of Public Health found a significant decrease in blood flow in eight different regions of the brain. One of these brain locations was near an important region of the brain that controls memory which is called the hippocampus.

The researchers examined cerebral blood flow on healthy, physically fit, adult athletes (ages 50-80 years) using an MRI (magnetic resonance imagine) scan. Measurements were taken while athlete's were still following their regular exercise routines and then again after 10 days of no exercise activity.
Their exercise regimes consisted of at least four hours of high intensity exercising each week.

According to Dr. Smith, impairment of the hippocampus can lead to increased risks of Alzheimer's disease in older adults. This study provides information that stopping exercise can not only be harmful to cardiovascular health, but also cognitive health as blood flow is significantly decreased around important regions of the brain.

Exercise has been proven to reduce the loss of brain tissue in older adults

Another study measured differences in the brain tissue consisting of gray matter and white matter. The research shows that exercise can help to preserve this brain tissue in older adults when they are participating in regular exercise. The study concluded that older adults are encouraged to exercise because it helps to improve their cognitive function as it naturally declines. This information can be used to prove that participating in exercise can be very beneficial to adults and lead to a healthier life both mentally and physically.

Scientific evidence reinforces the importance of exercise for older adults

These studies propose new information about the impacts of exercise on cognitive function in older adults. With the frequent decrease of physical activity seen in older adults, this information can be used to reinforce the benefits that exercise can present for cognitive health. The decrease in blood flow around the hippocampus could be related to the development of Alzheimer's disease. Research suggests that having a good functioning memory is very important for older adults as they are already at risk for this disease and stopping exercise may only heighten this risk. Further research can be done to find what the long-term effects could be and if exercise could reverse these effects once resumed.

Although the main headline is quite explanatory, the subheads need to be a bit more specific. For example, the third subheading does not accurately explain how exactly scientific evidence reinforces the importance of exercise in older adults.

As far as the actual text, I believe you did a pretty good job chunking and organizing the text during the first half of the article. However, towards the end, the chunking style was inconsistent with the first half as there are bigger chunks of text. I also believe you did a good job with the placement of the photos and the video even though the first photo is not all that explanatory which can be hard for scanners to get all the information they need.
