Junxiu Liu, MD, of the University of South Carolina published an article in the September 15 , 2014 edition of the Journal of the American College of Cardiology showing that exercise and improving fitness levels prevented an age related expected rise in patient systolic blood pressure. His study followed 14,000 men for 35 years. Sedentary men started to see their systolic blood pressure rise at about age 46. Men who were fit delayed this rise in blood pressure until they were 54 years of age. The effect on the diastolic blood pressure was even more pronounced when looking at fitness levels. Men with low fitness ratings elevated their diastolic blood pressure to above 80 by age 42. Those men with a high fitness level did not see the rise in diastolic BP until they were beyond age 90. His research suggests that “highly fit men are likely to reach abnormal BP readings a decade later or more than sedentary men.
In an unrelated study published in the same issue, researchers in Texas found that regular aerobic exercise prevented the hearts left ventricle or main pumping chamber from developing stiffness. The stiff ness of the ventricle contributes too many common cardiovascular conditions effecting older patients. They found that low levels of casual lifelong exercise such as four (4) sessions of 30 minutes per week throughout adult hood was sufficient to keep the ventricle from stiffening.
Marco Perez, MD of Stanford University looked at exercise levels in women and the development of the heart arrhythmia atrial fibrillation. He found that sedentary women were much more likely to develop this pathologic arrhythmia than women who exercised regularly. Obesity and being overweight is a risk factor that increases your chances of atrial fibrillation. Regular exercise by obese women reduced this risk by about nine percent (9%).
The message is very clear that keeping moving and being active improves your blood pressure control and reduces your risk of developing many cardiovascular related problems. My advice is find some activity you enjoy doing and make sure you try it several times per week to gain the natural benefits the exercise provides.
