Benefits Of Cardio
Interval Training
The benefits of cardio interval training are
considerable. In a long-term study of the health of the people of in the United
States, the U.S. Public Health Service documented the chances of developing
heart disease among various groups in the population. Long before the any
symptoms appeared, epidemiological research could identify high-risk groups.
Among the highest risk factors are male sex, age over 35, cigarette smoking,
high blood pressure, high levels of certain blood fats, and a family history of
cardiovascular disorders.
Other researchers have added to this list another risk factor: the compulsive,
hard-driving, highly anxious personality. The greater the number of severity,
the greater the person’s overall risk.
These threats to the heart can be divided into two main categories: those beyond
individual control, such as age, sex, and heredity, and those that can be
controlled, avoided, or even eliminated. Among those in the second category are
what cardiologists call “the triple threat.” These are the high blood pressure,
cigarette smoking, and high cholesterol levels in the blood.
If you smoke a pack of cigarettes a day, your risk of having a heart attack is
twice that of a nonsmoker. If you smoke, have hypertension, and eat a diet high
in fats without any exercise at all, your risk is five times greater than
normal.
Cardio Interval Training: You Way to a Healthy Heart
If these risk factors endanger the heart’s health, what enhances its well-being
and improves its odds of working long and well?
Obviously, quitting cigarettes and eating a low-fat diet will help. The next
best thing you can do for your heart’s sake is to give it what it needs: regular
exercise or a complete cardio interval training.
The heart is a muscle, or, more accurately, a group or “package” of muscles,
similar in many ways to the muscles of the arms and legs. And just as exercise
strengthens and improves limb muscles, it enhances the health of the heart
muscles as well.
Since World War II, several large-scale statistical studies have evaluated the
relationship between physical activity and cardiovascular disease. One
well-known survey compared 31,000 drivers and conductors of some bus companies.
The more sedentary drivers had a significantly higher rate of heart disease than
the conductors, who walked around the buses and climbed stairs to the upper
level.
The why and how behind these statistics were best explained by classic
experiments with dogs whose coronary arteries were surgically narrowed to
resemble those of humans with arteriosclerosis. Dogs who were exercised were had
much better blood flow than those kept inactive.
The exercise seemed to stimulate the development of new connections between the
impaired and the nearly normal blood vessels, so exercised dogs had a better
blood supply to all the muscle tissue of the heart. The human heart reacts in
the same way to provide blood to the portion that was damaged by the heart
attack.
To enable the damaged heart muscle to heal, the heart relies on new small blood
vessels for what is called collateral circulation. These new branches on the
arterial tress can develop long before a heart attack — and can prevent a heart
attack if the new network takes on enough of the function of the narrowed
vessels.
With all these facts, it is now boiled down to a single question: What should be
done in order to prevent such dilemmas?
Some studies showed that moderate exercise several times a week is more
effective in building up these auxiliary pathways than extremely vigorous
exercise done twice as often.
The general rule is that exercise helps reduce the risk of harm to the heart
(with cardio interval interval training even better). Some researchers further
attested that the link between exercise and healthy heart based from the
findings that the non-exercisers had a 49% greater risk of heart attack than the
other people included in the study. The study attributed a third of that risk to
sedentary lifestyle alone.
Hence, with employing the cardio interval training, you can absolutely expect
positive results not only on areas that concerns your cardiovascular system but
on the overall status of your health as well.
This particular activity that is definitely good for the heart is a cycle of
“repeated segments” that is of intense nature. In this process, there is an
interchange periods of recuperation. It can both be comprehensive activity and
moderate motion.
Consequently, merely engaging cardio interval training can produce more results
that you have ever expected. These include:
1. The threats of heart attack are lessened, if not eliminated
2. Enhanced heart efficiency
3. Increase metabolism, increasing the chance of burning calories, therefore,
assisting in losing weight
4. Improved lung capacity
5. Lessening or eliminating stress
Indeed, cardio interval training is the modern way of creating a healthy, happy
heart and body.
