if we burn more calories than we eat,
we lose weight. When resting the body
burns around 70 calories per hour to
keep our vital functions active.
The body's work rate is reflected by
the rate of the heart beat (pulsations)
which increases as the work rate
increases. The effort in your treadmill
depends on the speed. If you increase
the speed, the work rate and the heart
rate increase too. If the work rate
maintains constant, the heart rate
increases up to a point where no
matter how much work increases the
heart does not beat any faster. This is
known as the maximum heart rate and
it decrease with age.
A familiar formula for calculating this
maximum
heart
exhaustion sets in, is 22 minus age.
Exercising should be carried out at
between 65% to 85% of the maximum
heart rate for 15-20 mins and it is
recommentded that is should not
exceed 85%.

EXERCISE PROGRAM.-
Before starting any exercise program,
bearing in mind that exercise programs
vary depending on age and physical
condition, it is advisable to consult your
doctor given that you will achieve better
results based on his/her advice or
suggestions. Regardless of whether
your goal is to become fitter, control
your weight or for physiotherapy, always
remember that your exercise should be
gradual, planned, varied and not too
demanding. We recommend that you
should exercise 3 to 5 times per week.
Before beginning a session it is
important to do a warm-up for 2-3
minutes at low speed. This will help
protect your muscles and prepare your
cardiorespiratory system.
The next stage will last 15-20 minutes at
a pulse rate of between 65 to 75%, or
between 75 to 85% for those already
accustomed to exercise. At a later
stage, once we have become fitter, we
can divide this time between both levels
but always remembering that the pulse
rate must not exceed 85% (aerobic
area) and never reach the maximum
