Exercise
differ by the duration and intensity of muscular
contractions involved, as well as by how energy is
generated within the muscle. Initially during
aerobic exercise, glycogen is broken down to produce
glucose, which is then broken down with the help of
oxygen to generate energy. In the absence of these
carbohydrates, fat metabolism is initiated instead.
The latter is a slow process, |

Anaerobic exercise, in contrast, refers to the
initial phase of exercise, or to any short burst
of intense exertion, in which the glycogen or
sugar is consumed without oxygen, and is a far
less efficient process. developed world,
there is a substantial market for products which
promise to make weight loss easier, quicker,
cheaper, more reliable, or less painful. |

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
