General Fitness And Weight Loss |
Almost everybody wants to be fit
and in good shape. Here are a series of tips and
articles giving advice and motivation to achieve a
good level of general fitness and to loose weight.
4.) Benefits Of Cardio Interval Training
__________________________________________________________________
Benefits of Cardio Interval Training
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
non-smoker. 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.
