Hamilton Personal Trainer Talks About Physical Inactivity!!
By murray | June 3, 2009
Like any other muscle in our body, the heart must be exercised regularly or it will gradually become weak and more prone to disease. The importance of physical activity in strengthening the 
heart cannot be over-emphasized. Covert Bailey, one of the leading authorities on health and fitness, summed up the beneficial effects of exercise best: “If exercise could be condensed into the form of a pill, it would be the single most prescribed medication in history”. Not only is cardiovascular exercise recommended to prevent heart disease, it is frequently used by doctors to treat patients who have already suffered heart attacks.
Aerobic or cardiovascular exercise enlarges the coronary arteries which supply the heart muscle tissue with oxygen and nutrients. Exercise increases collateral circulation so that more than one blood vessel will supply blood to the same area of the heart. In other works, exercise helps provide a backup system of blood vessels that can take over if the blood supply becomes blocked in one artery, thereby preventing a possible heart attack. Exercise also makes the heart more efficient at extracting oxygen from the blood. In addition, among its other multitude of benefits, aerobic exercise of moderate intensity may lower blood pressure in people with hypertension.
In summary, participating in a regular cardiovascular exercise program may: decrease resting heart rate, percentage of body fat, blood cholesterol levels,both systolic and diastolic blood pressure and stress levels. All the while increasing the size and strength of the heart, the muscles’ ability to burn fat, cardiovascular capacity, physical work capacity, efficiency of the heart and lungs, stroke volume and blood volume.
