THE EFFECTS OF AEROBIC EXERCISE ON THE CARDIOVASCULAR SYSTEM

Aerobic exercise is any activity that uses large muscle groups that can be maintained continuously for longer periods of time (more than 30 minutes) and are rhythmic in nature. It relies on aerobic metabolism to extract energy in the form of adenosine triphosphate (ATP) from carbohydrates, amino acids, and fats.

Some examples of aerobic exercise are:

Jogging

Cycling

Rowing

Hiking

Swimming

Walking, etc.

 

It is different from anaerobic exercise in that it needs to utilize oxygen to create energy.

The effect of aerobic exercise on the cardiovascular system is:

Regular aerobic exercise improves your cardiovascular performance by increasing your capacity to use more oxygen.

Aerobic exercise increases the heart pumping chambers (ventricles) and therefore it increases the amount of blood sent to the body's muscles. This means the heart doesn't have to beat as often to deliver the same amount of blood. Which in turn has the following benefits/positive changes.

Increase in exercise tolerance - this also means less fatigue from day-to-day activities and more energy in general to accomplish different tasks. Less chance of Cardio Vascular disease - Studies have shown that increasing the CV system performance has reduced the likelihood of cardiovascular disease by as much as 50%.

Reduction in blood pressure - Because the heart can pump more blood, the force on your arteries decreases, lowering your blood pressure.

Healthier skin - with a more efficient CV system, circulation improves, which in turn delivers more blood to your organs and skin.

Less stress on the lungs - because more blood is being pumped, there is less stress on the lungs because you do not need to breathe as often.
