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 personís 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 ìthe triple threat.î 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 heartís 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 heartís 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 ìpackageî 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 ó 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 ìrepeated segmentsî 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.

Our body reacts to strenuous activity like distance running in two ways: acute reaction and training effect. Acute reaction is when your heart rate speeds up, your stroke volume increases, your ventilation rate and depth of breathing increase, your blood pressure rises, and your muscles feel some fatigue. However, when an activity becomes regular routine to you, you will eventually feel the second reaction which is the training effect.
It is when your body gets used to chronic exercise; your muscles feel stronger and less discomfort to physical activity. Through training, your blood flow increases that it allows you to produce more energy and less lactic acid to accumulate during exercise. Your resting heart rate becomes slower caused by a stronger heart that can pump more blood per beat. You will also most likely develop a lighter, springier step, lower resting blood pressure, lower body weight, and less fat under the skin.
Your body now can tolerate stress and ready for competitive efforts. "The system you stress during exercise is the one that stands to benefit from the stress," wrote Jack Daniels in his book Daniels' Running Formula. However, the principle of specificity restricts you to achieve gains through performing another activity. By doing another activity, you take yourself away from your primary interest and might produce results that limit performance in your main activity. Long distance running has negative effect on performing explosive leg activities like sprinting and jumping. Thus, you must give considerable thought to every aspect of your training and you must keep in mind that everything you do affects you and your body's reaction.
Adding a new level of stress on top of your current training further increases your fitness level. In distance running, if you have performed a training routine regularly and reached a stable level of proficiency, you can possibly take more training modifications (for frequency, duration, intensity, or recovery) which will lead you to a new level of fitness. For example: you can increase the training frequency from three to four days per week, you can increase the amount of training from three to four miles per session, or you can increase the distance of each interval from one mile to one half and a half each. Another possible modification is to change the recovery time allowed between the mile runs within a workout.
Sticking with a training program for longer than six weeks produces more benefits. If you want to increase training, the best time is after six weeks of adapting to a specific training stress. The primary risk of increasing training too often and too soon is an escalated risk of injury and overstress. There are limits to training for distance running.
Overstressed system can affect variety of activities other than just the activity that caused the damage. For example, a stress fracture in leg caused by too much running or improper running can restrict a runner from doing other activities that stress the injured extremity. Thus, it is important to watch out for abuses that you can possibly do as you try to reach your goals. You must learn to accept that even you are physically active; your body has still limits that dictate your success.
In distance running, few people realize their limits and improvements are always possible. However, keep in mind to take things at the perfect timing.
