Our human body is like a
machine. The body uses fuel and produces heat and energy. But there are many
differences, and one of those is the effect of activity. Constant use of a machine
wears it out sooner than the ones used only occasionally.
Several interesting studies
published in England show the relationship between physical fitness and comparative
freedom from coronary artery disease. A physically fit youth avoids much
illness. Also, body and mind are so interrelated that a physically robust youth
can use his mind more efficiently and therefore can benefit more from his or
her studies. The facts are that today’s youth do not possess the physical
strength, the flexibility and the endurance compared to the youth in the past
generations. They are frail because they didn’t follow the example of their elders
in considering exercise necessary. Too often they rely on mechanical devices rather
than their muscles. Most children and youth today do not even walk to and from
the school. Youth is the ideal time for developing the heart and lungs. A heart
never put to the stretch to supply the demands of active muscles will not
develop strength and endurance necessary for lifelong physical fitness.
Lungs which do not expand to
their limit will not develop their maximum capacity for transmitting oxygen to the
bloodstream. Muscles remitted to remain flabby will not do their part in
maintaining a good, correct, elastic posture.
What type of
Exercise?
The choice of physical activity
will depend upon several factors: the age and vigor of the individual, the weather,
the time a day available for exercise, the availability of funds for special
equipment, the opportunity for combining exercise with recreational interests,
and the preferences of the individual.
Of all possible forms of
exercise walking comes first. It is adequate and is convenient to all. It
requires no equipment, and is suited to individual tolerance. Walking brings
into play most of the body’s muscles. Gymnasium activities are excellent
especially when weather and climate make outdoor activity impractical.
Setting-up exercises, taken at home, also serve well to keep a person in good
condition.
These require no special
equipment and can be varied to suit the tolerance of the individual. Push-ups, sit-ups,
and other such forms of muscle development can be carried on systematically. By
making the exercises a little more strenuous each week, a person can build up
his physical fitness to a satisfactory level.
Warning
Middle-aged persons
particularly must be cautioned against letting their enthusiasm cause them to overdo.
As with all other good things, there are extremes to be avoided. The following danger signals serve as
indication that the program of exercise is strenuous: The heart continuous to
pound for more than ten minutes after exercise has ceased. (2) Breathing is still
uncomfortable following a ten minute period of rest. (3) The muscle feel shaky
for more than thirty minutes after the exercise. (4) it is hard to relax when
bedtimes comes. (5) The person feels unusually tired on the following day.
Benefits of
Exercise
Exercise builds muscles,
increasing their blood supply, their power, their efficiency, and their endurance.
(2) Exercise improves the circulation of blood throughout the body by
increasing the capacity of the heart to pump blood. Improved circulation of
blood throughout the body benefits the heart itself. Thus, exercise makes the
individual less susceptible to the heart attack. (3) Exercise improves the
efficiency of the lungs, thus providing a readily available supply of oxygen.
(4) Exercise improves the functions of many tissues throughout the body by
increasing the metabolic activity of all tissues. (5) Exercise helps in the
control of body weight, using up surplus calories. (6) Exercise promotes a
feeling of zest and well-being, and this provides greater vigor for the day’s
activities. A person physically fit is likely to become more optimistic, enthusiastic,
and successful. (7) Systematic exercise reduces end-of-the-day fatigue. (8) Exercise
when properly chosen becomes an enjoyable form of recreation and thus relieves
enervating monotony.
A well-nourished person
provided to exercise regularly and follows a consistent program of healthful
living possesses the following characteristic: He has abundant vitality. His
facial expression radiates well-being, his eyes appear clear and alert and his
hair is smooth and glossy. (2) his bones are well-formed. He has sturdy arms
and legs, a straight back, well-shape head and chest, and well formed-teeth.
(3) His muscles are well-developed and strong. He has a good posture when
sitting, standing, or walking. His movements are graceful and he seems to find
pleasure in physical activity. (4) he has sufficient fat beneath his skin to
pad the underlying bones and muscles, but is not overweight. (5) His body
functions efficiently. He enjoys food, and his organs of digestion and
elimination functions normally. He has good endurance. In describing a
well-nourished person, we have simply described a healthy person. This a
logical for the food a person eats provides the raw material out of which all
body processes are supported and maintained.
The ideal state of health
comes partly from sufficient protein in the diet to provide for the formation
and repair of body tissues. There must be an adequate supply of minerals to
reinforce the body tissue, as in the formation and maintenance of teeth and
bones. There must be sufficient carbohydrates for energy and the right amount
of fat. There must also be vitamins to keep the tissues in good condition and to
enable the brain, the nerves and other vital organs to function well.
