2. Aerobics
 Aerobic fitness is related to health.
 In the United States, over 800,000 people die each year from coronary
artery disease (CAD) which is the number one killer in the United States.
 The risk factors for CAD include: Inactivity, high cholesterol levels,
smoking, overweight, high blood pressure, and diabetes.
 Numerous studies have shown that inactivity is the most important
factor responsible for CAD.
 It is twice as important as high cholesterol levels, and four times more
important than high blood pressure.
 Consequently, exercise reduces the risk of dying from a heart attack and
it is an effective method of rehabilitation in people who have suffered
from a heart attack.

3. Related effects of exercise
include the following:
 Lowering of high blood pressure.
 Increasing the high density lipoprotein (HDL) in the blood
which helps collect the cholesterol in the blood and dispose
of it in the liver.
 Lowering the plasma triglyceride levels (fatty substances).
 Assisting in weight control, mainly by reducing body fat.
 Improving the function of the heart, by promoting beneficial
changes in the structure and function of the coronary arteries
(which provide oxygen to the heart muscle.
 Alleviating muscle pain and improving walking capability in
people who suffer from peripheral arterial disease.

4. Aerobic Fitness. Its Meaning
and Significance
 "Aerobic fitness" refers to endurance, or the ability to sustain
work for prolonged periods.
 This is usually experienced in the abilities to walk, run, climb
uphill, swim, etc.
 Most forms of sports, work, recreational and military activities
include elements of aerobic fitness. Generally speaking, any
activity which lasts less than 12 minutes is not fully aerobic.
 The term "aerobic" implies that the oxygen necessary to
accomplish the work is taken up by the individual during the
activity.
 Strenuous exercise lasting less than 12 minutes includes
substantial portions of anaerobic metabolism whereby one
uses energy sources stored in the body to perform the work.

5. Aerobic Fitness. Its Meaning
and Significance
 Since the body's energy sources are limited, anaerobic
work cannot last long.
 Fast runs, lasting 10 to 15 seconds, are mostly
accomplished by anaerobic metabolism.
 With longer exercise time, more aerobic metabolism is
involved, and exercise lasting more than 12 minutes is
mostly accomplished by aerobic metabolism.
 Work is performed by the muscles which use oxygen for
the combustion of fat and carbohydrates creating the
energy necessary to move the body, or to move objects
outside the body.
