Benefits Of Cardio Interval Training
Who's most at risk for Heart Disease?
Who's most at risk for Heart Disease?
In a long-term study of the health of the people of in the United States, the U.S. Public Health Service studied the probability of developing heart disease among various groups in the general population. Long before the any symptoms appeared, epidemiological research could single out high-risk groups by examining the risk factors.
The highest risk factors are males over 35 years of age who smoke cigarettes, have high blood pressure and high levels of certain blood fats. A family history of cardiovascular disorders is also an important risk factor.
Another key factor that other scientists have added to this list is a compulsive, hard-driving, highly anxious personality. The greater the severity of this personality type, the greater that persons overall risk will be.
These threats to the heart can be divided into two main categories:
Factors beyond individual control:
-Age
-Sex
-Heredity
Factors that can be controlled or even eliminated:
-High blood pressure
-Cigarette smoking
-High cholesterol levels in the blood
The items in this second grouping are what cardiologists call the triple threat. 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 a normal person's.
The Healthy Heart
If these risk factors jeopardize the hearts health, what enhances its well-being and improves its odds of working long and well? Without a doubt, kicking the cigarette habit and eating a low-fat diet will help.
The next best thing you can do for your heart is to provide it the two things that it needs:
-Regular exercise
-Complete cardiovascular 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 the endurance of your arm and leg muscles, it enhances the health of the heart muscles as well.
After World War II, several large-scale statistical scientific studies have evaluated the connection between physical activity and cardiovascular disease. One well-known survey compared 31,000 drivers and conductors of bus companies. The more inactive drivers had a significantly higher rate of heart disease than the conductors, who walked around the buses and climbed stairs to the upper level.
Why this was the case with this survey was best explained by classic experiments with dogs. Their coronary arteries were surgically narrowed to resemble those of humans with arteriosclerosis, or hardening of the arteries. Dogs who got more exercise had much better blood flow than those who were forced to remain inactive.
The exercise appeared 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 of the heart that was damaged by the heart attack. It's all about the heart getting enough oxygen rich blood delivered from the lungs to the heart muscles.
To permit the damaged heart muscle to heal, the heart relies on new small blood vessels for what is called collateral circulation. These new blood vessels can develop long before a heart attack and even prevent a heart attack if the new network takes on enough of the function to make up for the narrowed vessels.
With all these facts, it is now resolves to a single question: What may be done in order to keep from having these problems?
Some research showed that moderate exercise several times a week is more effective in building up these auxiliary pathways than extremely vigorous exercise done less often. The general rule is that exercise helps reduce the risk of harm to the heart. Some researches confirmed 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 a sedentary lifestyle alone.
When using cardio interval training as your exercise regimen, you can absolutely expect positive results not only on areas that concerns your cardiovascular system but on your overall health as well. This particular activity, interval training, that is definitely good for the heart consists of a cycle of repeated segments. In this exercise routine, this dynamic activity is followed by intervals of recuperation. It can both be comprehensive activity and moderate motion. As a result, the benefits of simply engaging into this kind of activity can give you more results than you might have ever expected.
These results are as follows:
1. Heart attack threats are lessened, if not eliminated altogether.
2. Enhanced heart function.
3. Increased metabolism and increased calorie burning. Therefore it will assist you in losing weight.
4. Improved lung capacity.
5. LessenedDecreased or eliminated stress. Very important!
The elimination of stress leads to a healthier mind and body. Remember to monitor your heart as you follow this exercise routine. You can use a Heart Monitor Rate Watch to help you meet your targets while keeping your heart rate in a healthy range. It can be said that cardio interval training is the modern way of creating a healthy, happy heart and body.
