ABSTRACT

Aerobic literally means "with oxygen", and refers to the use of oxygen in muscles' energy-generating process. Aerobic exercise includes any type of exercise, typically those performed at moderate levels of intensity for extended periods of time that maintains an increased heart rate. In such exercise, oxygen is used to "burn" fats and glucose in order to produce adenosine tri-phosphate, the basic energy carrier for all cells. Initially during aerobic exercise, glycogen is broken down to produce glucose, but in its absence, fat starts to decompose instead. This latter is a slow process and is accompanied by a decline in performance level. Aerobics is an effective physical exercise which is often done to music. It can be defined as "any activity that uses large muscle groups, can be maintained continuously and is rhythmic in nature." Aerobic exercise is any repetitive activity that you do long enough and hard enough to challenge your heart and lungs. In order to work your heart and lungs hard enough, you must get your largest muscle groups involved. They include your legs, gluts, back and chest. It is a type of exercise that overloads the heart and lungs and causes them to work harder than at rest. The important idea behind aerobic exercise today, is to get up and get moving!! There are more activities than ever to choose from, whether it is a new activity or an old one. Find something you enjoy doing that keeps your heart rate elevated for a continuous time period and get moving to a healthier life.
