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.
The 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 bet 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 often.
The general rule is that exercise helps reduce the risk of
harm to the heart. Some researches further attested 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, the benefits of merely engaging into this kind
of activity can bring you more results that you have ever expected. These are:
1. The threats of heart attack are lessened, if not
eliminated
2. Enhanced heart task
3. Increase metabolism, increase the chance of burning
calories, therefore, assist you in losing weight
4. Improves lung capacity
5. Helps lessen or eliminate the cases of stress
Indeed, CARDIO INTERVAL TRAINING is the modern way of creating
a healthy, happy heart and body.
