Heart resistance
and advantages
of exercising
BY JOAQUIN
ORAMAS
WITH aging, a
series of physiological and body changes occur. The
elderly usually experience a significant decrease of
strength and muscular mass as a consequence of long
periods of inactivity.
According to experts, old age begins
at age 60-65. At this age, cells wear away,
provoking bodily changes, which demand a strong will
and daily activities that were unimportant in
earlier stages of life.
Exercising is one of those
activities, not only to live a healthy life in all
aspects, but mainly to help the body function
properly so that we can avoid coronary disease and
blood pressure problems.
Keeping fit is very important
because a sedentary life weakens the muscles and
slows down circulation. Doctors advise that physical
activity is not restricted to the gym since we may
well meet our daily exercise needs by walking for at
least 40 minutes per day.
Cycle rides, swimming and gardening
are other options to help safeguard health.
The thickening of veins and arteries
indicates that there is a deterioration leading to
blood circulation problems. This provokes
hypertension.
We should not forget that
hypertension is a risk factor in all cardiovascular
disorders, including brain and heart injuries.
Not only the elderly need a training
program appropriate to their body and age, but
physical activity is important throughout our entire
lives and its benefits are innumerable, heart
resistance being perhaps its largest advantage.
When we exercise at a certain
intensity for over two minutes, our muscles demand a
large amount of oxygen. These activities oblige
those who exercise regularly to increase their heart
resistance, consisting of the continuous capacity of
the blood to carry oxygen to the cells.
An increase of heart resistance also
assumes a certain capability of the tissues, and
each one of its cells to process oxygen and
eliminate the residue produced by this process.
At a certain age, and mainly when
one has lived a sedentary life and had a diet too
rich in fats, that capability of the tissues may be
compromised, putting the heart at risk.
The heart is able to develop a
certain resistance when we subject it to efforts. If
the heart can efficiently function for a prolonged
time under circumstances more demanding than normal,
this organ will not have major problems pumping
blood in our daily life, supposedly much more
relaxed. The heart will not be affected either when
facing situations demanding a prompt response.
Constant exercising for long periods
of time produces innumerable benefits for people of
all ages.
In recent decades, the elderly
population has grown, and scientists have
increasingly concentrated on the conditions
necessary for a healthy old age: a proper diet,
exercising, a favorable environment, cultural level
and motivation.
In sum, a lifestyle seeking to
prolong life to 120 years or longer.
