removed. Blood also transports hormones from the glands to various parts of the body, as well as vitamins and nutrients form the digestive tracts. When the blood vessels become clogged due to plaque build up of cholesterol and fat, the heart muscle must work twice as hard to pump enough blood to our vital organs. Hence, this causes high blood pressure. As the pressure increases inside the arteries, veins, and capillaries, the heart becomes even more overworked.
Experts recommend that people maintain a blood pressure lower than 140/90 mmHg at rest (O"Rorke & Richardson, 2001). The higher number represents the maximum pressure exerted when the heart contracts (systolic). The lower number represents the pressure exerted when the heart begins to relax between beats (diastolic). Many studies have been conducted to determine how to reduce blood pressure in humans. Drug therapy is one of the most widely spread ways to treat high blood pressure along with a change in diet, but exercise is also a great way to lower blood pressure and fight plaque buildup. .
Review of Literature.
Researchers in the Heritage Family Study chose 507 healthy, sedentary participants with mildly high blood pressure to participate in their experiment. The study was conducted to determine the magnitude of change in resting and exercise heart rate, and blood pressure by race, sex and age after a twenty-week endurance-training program. .
exercise and hypertension 3.
Subjects exercised on cycle ergo meters three days a week for a total of sixty exercise sessions. The sessions started at 55% of maximum oxygen uptake (VO2max) for thirty minute sessions and built up to 75% VO2max for fifty minute sessions for the last six .
weeks. After the period of training there was a small decrease in resting heart rate across groups and small changes in resting systolic, diastolic, and calculated mean blood pressure, which varied by race, sex and age.
