The definition of aerobic is “requiring air”
Aerobic exercise occurs when large muscles are in continuous motion, moving rhythmically, and pulling oxygen into the body’s tissues. Cardiac conditioning is a particular form of aerobic exercise that is designed to stress the heart so it will grow stronger and have increased endurance, or to maintain good levels of strength and endurance.
Most American people lead a sedentary lifestyle, which means that more exercise is needed. Aerobic exercise is one of the most effective ways to lose weight. Contrary to what many people think, it is not the intensity of the exercise that leads to weight loss, but the amount of time that we are performing the exercise.
After about thirty minutes of aerobic exercise, the longer we continue to exercise, the more fat we will burn. Diets where we count calories often do not work, because by restricting caloric intake, we send a message to the body that it is starving. This causes the body to slow down our metabolism so that it actually burns calories even more slowly.
Exercising with tight, unstretched muscles can lead to injury. A good stretch to the major muscle groups can prevent this. It is important to have a warm-up period at the start of aerobic exercise and a cool-down period at the end. These periods allow the body to adjust to a sudden change in activity level, so that exercise-induced dilated blood vessels can return to resting rates. Without the preparation at the beginning and the end of exercising, suddenly stopping aerobic exercise can lead lightheadedness, fainting and even a heart attack.
