Cardiovascular fitness promotes the loss of body fat and has been
reported to actually decrease the appetite in many individuals. However,
even if it doesn’t reduce appetite, the calorie-burning effects of
regular aerobic exercise can allow for substantial caloric intake. Many
endurance athletes regularly consume between 3,000-5,000 calories per
day and remain extremely lean. Cardiovascular training, when combined
with a sensible diet, will definitely promote an increase in lean body
tissue and a decrease in body fat percentage.
The skeletal system can be strengthened by weight-bearing activities
such as fast walking and jogging. This can not only assist in reducing
the risk for developing osteoporosis, it can also help to slow down the
progress of the disease for those whose doctors recommend exercise.
Aerobic exercise is often part of treatment programs for diabetics whose
blood sugar is well controlled. This is due to the fact that aerobic
training increases the sensitivity of the cells to insulin so diabetics
who exercise regularly require less insulin to effectively regulate
blood sugar levels. In addition, studies have shown that persons with
adult-onset diabetes have been able to significantly reduce or eliminate
medications other than insulin by following a regular exercise program
combined with a healthy diet.
Cardiovascular exercise is often a major component of the therapy for
those who have suffered a heart attack and for those who are at high
risk for coronary artery disease. Three of the primary risk factors for
developing coronary artery disease are high blood pressure
(hypertension), smoking and high blood cholesterol. Cardiovascular
exercise can play a significant role in reducing risk associated with
these three factors.
First of all, many people with high blood pressure are also overweight.
Regular sessions of aerobic exercise will reduce body fat and lower
blood pressure. Secondly, many people who smoke find the incentive to
quit after embarking upon an aerobic exercise program. Thirdly, regular,
brisk, cardiovascular training leads to an increase in the level of high
density lipoprotein (HDL), also known as the “good” cholesterol.
Those with arthritis can benefit from aerobic exercise to help them
maintain an ideal body weight. Therapy programs for arthritis sufferers
should also include appropriate exercises to help maintain joint range
of motion. This can be incorporated into an overall exercise program
that includes cardiovascular exercise.
Cardiovascular exercise has also been shown to decrease clinical
symptoms of anxiety, tension and depression. Regular aerobic workouts
increase blood flow and assists the body in eliminating toxins which can
make a person feel better.
On a physiological level, cardiovascular fitness decreases resting heart
rate and increase heart volume. It increases maximum oxygen consumption,
capillary density and blood flow to active muscles. It also increases
total blood volume, allows for maximal ventilation and increases lung
diffusion capacity.
Cardiovascular training serves as the foundation for other fitness
programs. The conditioning and health of the heart and blood vessels are
the basis for safety and performance in nearly all athletic endeavors.
