Exercise is important to maintain our health.
Even a moderate walk as exercise starts a chain-reaction,
and as a start it causes the skeleton muscles to become more active.
As the muscles warms up, more heat is given off.
Body temperature remains almost the same, because the body’s automatic
air conditioning system starts to disperse the extra heat through the skin.
As more blood sugar is turned into energy, more carbon dioxide gas will
be expelled in the air we breath out, and blood will flow more rapidly
through the muscles. The breathing will become deeper, and the heart beat
and blood pressure will be changed.

In more strenuous exercises, these processes will be stepped up.
More heat will be generated, the heart beat will be faster, blood-pressure higher,
breather deeper and faster, and the circulation more rapid.
The limiting factor in strenuous exercises is the oxygen supply,
and when this limit is reached, oxygen fatigue is experienced and
the exercise has to stop.

Need for Exercise
Exercise has been recognized even in sickness.
Physicians are not permitting patients with organic ailments to stay in bed
as long as before. According to “The American Practitioner”,
’The evils of bed rest include the development of negative nitrogen balance and
calcium loss through the kidneys, with the possibility of developing kidney stones.’

The article also says:’nervous tension can be released at times by exercise,
either in the form of specific muscular exercise or through some form of athletics.’
Physio and occupational therapy are now standard procedures in medicine,

Those who’s occupation involves standing a long time, like dentists, teachers,
shop assistants, etc., are likely to develop phlebitis, i.e. the formation
of a blood clot – usually in the calf of the leg.
These people are advised to walk more and in addition. to take vitamin E
and lecethin capsules to improve the circulation, dissolve the clot and
prevent the formation of further clots.
Sufferers from rheumatism and arthritis, also those who are overweight,
are prone to take too little exercise. When people are troubled with
rheumatic twinges it is usually a sign that more exercise is needed and
that their diet contains too many acid-forming foods.

exercise, are troubled by ailments of degeneration which never affect
hard working sheep and cattle dogs.

Forms of exercise
Forms of exercise is a matter of personal preference.

and goals, each one should include aerobic exercise, and resistance and flexibility
training. Those components will help you improve your fitness level and help you
overcome obstacles that challenge your agility, balance, coordination, endurance
and strength in everyday life.
