Your risk of developing coronary heart disease, such as angina or a heart attack, is much reduced if you are regularly physically active. Inactive people have almost double the risk of having a heart attack compared with those who are regularly physically active. If you already have heart disease, regular Exercise is usually advised as an important way to help prevent your heart disease from getting worse.
Physically active people are less likely to have a stroke. One study found that women aged 45 and older who walk briskly (at least three miles per hour), or who walk for more than two hours a week, reduce their risk of stroke by a third compared with less active women.
Regular Exercise has been shown to raise levels of high-density lipoprotein (HDL) cholesterol. The link between cholesterol and CHD has been fairly well established through long term studies of individuals with high levels of blood cholesterol and the incidence of CHD. As high density lipoprotein cholesterol levels increase, they are independently associated with lower risk of CHD. It is also well established that a sedentary lifestyle contributes significantly to the development of CHD and to unfavorable elevation of blood fats and cholesterol levels; physical activity plays an important role in decreasing these health risks. Hypertension: Hypertension is a major health problem.
Elevated systolic and diastolic blood pressure levels are associated with a higher risk of developing coronary heart disease, congestive heart failure, stroke and kidney failure. There is a one-fold increase in developing these diseases when blood pressure is 140/90 millimeters of mercury (mmhg). In many cases, clients can reduce elevated blood pressure by decreasing weight and lowering alcohol and salt intake in their diet.
The evidence that higher intensity exercise is more or less effective in managing hypertension is at present inconsistent, owing to insufficient data. Although routine aerobic exercise usually will not affect the blood pressure of normal individuals, habitual aerobic exercise may be protective against the increase in blood pressure commonly seen with increasing age.
