United States: Groundbreaking research accentuates the profound effect of intense physical exertion in mitigating the threat of dementia for individuals grappling with elevated blood pressure. This investigation, featured in *Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association*, stated that partaking in strenuous physical activity more than once weekly can markedly diminish the incidence of mild cognitive impairment and dementia, even among those with hypertension.

Merits of Vigorous Physical Activity

Fitness is widely known for its wonders for the body, such effects like lowering of high blood pressure, improving the heart’s health and maybe, preventing dementia. Though the earlier study related to this fact was conducted some time back, the recent study led by Dr. Richard Kazibwe of Wake Forest University School of Medicine has unveiled a more accurate idea about the amount of exercised needed to deliver those benefits, as per the reports.

Instances of rigorous activities that yield these advantages encompass uphill hiking, running, brisk cycling, lap swimming, aerobic dancing, rope jumping, and strenuous yard labor. These activities, endorsed by the American Heart Association, necessitate considerable physical exertion and can significantly elevate heart rates.

Clinical Study and Its Revelations

The clinical trial encompassed over 9,300 participants aged 50 and above with hypertension, recruited from approximately 100 hospitals and clinics nationwide. The preliminary phase of the study unveiled in 2019, illustrated that stringent blood pressure control could substantially curtail the risk of developing mild cognitive impairment, a harbinger of early dementia.

Reportedly, in this latest analysis, researchers scrutinized the impact of vigorous exercise on cerebral health among these participants. The findings were promising: nearly 60% of participants reported engaging in strenuous physical activity at least once weekly, including those aged 75 and older.

“It is heartening to note that a significant number of older adults are partaking in physical exercise,” remarked Dr. Kazibwe. “This also indicates that older adults who acknowledge the significance of exercise might be more predisposed to engage in high-intensity workouts.”

Age and the Protective Efficacy of Exercise

Although the benefits of intense exercise were observed across all age brackets, the study discerned that the protective effect on brain health was more pronounced in participants younger than 75. This underscores the importance of integrating regular, high-intensity physical activity into one’s regimen earlier in life to maximize cognitive health advantages, as reported.

For individuals over 75, the benefits remained noteworthy, suggesting that it’s never too late to commence exercising. Consistent engagement in vigorous exercise can aid in sustaining cognitive function and reducing dementia risk, thereby contributing to an overall improved quality of life.
