Cardiovascular Health
Cardiovascular exercise refers to exercise that involves or improves oxygen consumption by the body, which in turn is Aerobic exercise. Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic or energy-generating process.

Many types of exercise are aerobic, and by definition are performed at moderate levels of intensity for extended periods of time. To obtain the best results, an aerobic exercise session involves a warming up period, followed by at least 20 minutes of moderate to intense exercise involving large muscle groups, and a cooling down period at the end.

Aerobic exercise comprises innumerable forms. In general, it is performed at a moderate level of intensity over a relatively long period of time. For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity, while golf or doubles tennis, with brief bursts of activity punctuated by more frequent breaks, may not be predominantly aerobic. Some sports are thus inherently "aerobic", while other aerobic exercises, such as fartlek training or aerobic dance classes, are designed specifically to improve aerobic capacity and fitness.

Among the recognized benefits of doing regular aerobic exercise are:

• Strengthening the muscles involved in respiration, to facilitate the flow of air in and out of the lungs

• Strengthening and enlarging the heart muscle, to improve its pumping efficiency and reduce the resting heart rate

• Toning muscles throughout the body

• Improving circulation efficiency and reducing blood pressure

• Increasing the total number of red blood cells in the body, facilitating transport of oxygen

• Improved mental health, including reducing stress and lowering the incidence of depression

As a result, aerobic exercise can reduce the risk of death due to cardiovascular problems. In addition, high-impact aerobic activities (such as jogging or jumping rope) can stimulate bone growth, as well as reducing the risk of osteoporosis for both men and women.
