The U.S. Public Health Service ongoing study of the lifelong effect of health within the population of the United States had recorded the chances of heart disease developing among the different categories of people.

Epidemiological research is the study of circumstances that is causing the health and illness of populations. The research are able to determine groups of people in the high risk zone even before they showed any signs or symptoms.

The study have identified a group with the highest risk as being a male, with the age of over 35, a cigarette smoker, having a history of high blood pressure, maintaining a high levels of some types of blood fats and having a family history of cardiovascular complications.

To add to that list, some researchers have included the uncontrollable, hard-driving and extremely anxious personality as another risk factor. The bigger the amount of severity, the higher the person's total risk.

There are two fundamental categories for these warning signs. First are those that are not in the control of the individual such as sex, age and heredity. The second one are the ones that is controllable, avoidable or even can be eliminated.

It is among those within the second classification are what cardiologists term as "the triple threats".

"The triple threats" category consist of cigarette smoking, high blood pressure and high cholesterol level in the blood.

Whenever a smoker puffs a pack of cigarettes per day, their risk of getting a heart attack is about twice that of a non-smoker. What is worse if you smoke, living with hypertension and consume food with enormous amount of fats without any exercise at all, the risk that you put yourself in is five times more than the normal people.

Now if this risk criteria are causing heart's health to be in danger then what will improves its well-being and better the odds of being functioning long and well?

It is definitely obvious that giving up smoking and eating nutritious diet that is low in fats will help you. Nonetheless, the next best action that you can provide for your heart's sake is to supply it with what it needs naturally and if you had guessed consistent exercise sessions or a complete cardio interval training then you are right.

What we know about the heart is that it consists of a group of muscles and it is no different to the muscles of the arms and legs.

These limb muscles are strengthened and improved with regular exercise and it will no doubt boost the health of the heart muscles too.

Many prominent statistical studies since the World War II have assessed the dependency between physical exercise and cardiovascular disorders.

There is a famous survey which compared over 30,000 drivers and conductors of a few bus companies. The drivers who are mostly in a sedentary sitting position had a very much higher rate of heart disorders than the conductors. The conductors had the chance to roam around the buses and climbed stairs to get to the top level of a double decker buses.

Another fine experiments involving dogs with coronary arteries that are surgically narrowed to mimic a human arteriosclerosis can clarify the why and how behind those statistics.

Compared with inactive dogs, those that are allowed to exercise had a healthier blood flow.

A new development between the connections of the imperfect and almost normal blood vessels seems to be stimulated by the workout. This mean dogs that are exercised had a healthier blood supply provided to the muscle tissue of the heart.

Looking at the human heart, it reacted exactly in the same fashion to transport blood to the part that was ruined by the heart attack.

The heart uses a new tiny blood vessels for a process called collateral circulation so that it can go about healing the damaged heart muscle.

These latest branches on the arterial tress are able to appear a long before a heart attack. If the new structure can take over efficiently the function of the narrowed vessels then heart attack can be avoided.

Gathering all of this facts, what action can we take to avoid such predicaments?

In constructing these subsidiary pathways, some studies have found that moderate workout a few times a week is more efficient for the task than an intensely vigorous workout done two times that frequency.

More supporting researches concluded that there are proven connection between exercise and a healthy heart based from the data that shows the group that do not exercise had almost 50% higher risk of heart attack than the other control group of people. The cause of a third of that danger, according to the study, is due to sedentary lifestyle alone.

Thus by getting involved in cardio interval workout, you can be sure to achieve positive development not only on aspects that concerns your cardiovascular system but also on the overall condition of you health too.

In a nutshell, merely committing into this type of exercise can lessen the threats of heart attacks, allows the heart to perform efficiently, increase metabolism, improves the lung capacity and decrease stress.

Have no doubt that cardio interval training is the sensible way of actualizing a healthy heart, mind and body.
