Note the position of the belt, if after one
minute the belt is not completely
centred then repeat the operation. If
you see that the belt has moved too far
over to the right then turn the left screw
back slightly in an anticlockwise
direction. Fig.8.
Important:
Overtightening of the belt
can lead to a loss of speed on the
machine and even stretch the belt
itself. Bear In mind that one turn of the
right screw (R) in a clockwise direction
has the same effect on the position of
the belt as one turn of the left screw (L)
in
an
anticlockwise
direction.
Consequently, in the event of
excessive belt movement you can use
either of the two screws in order to
avoid overtightening the belt.
OPERATING INSTRUCTIONS.-
FITNESS.
Being fit means living life to the full.
Modern society suffers greatly from
stress. There are too many calories
and too much fat in our diet. All
doctors agree that regular exercise is
a good way to control our weight,
make us fitter and help us to relax.
ADVANTAGES OF EXERCISE.-
Regular exercise below a certain level
for 15/20 minutes becomes aerobic.
Aerobic exercise is basically exercise
that uses oxygen. Normally, this is a
continuous exercise without pauses.
In addition to sugars and fats, the
body also needs oxygen. Regular
exercise improves the body’s ability to
supply oxygen to all of the muscles
and at the same time improve lung
function, the heart’s pumping capacity
and better blood circulation. In short,
the energy produced during exercise
burns kilocalories (known as calories).
EXERCISE & WEIGHT
CONTROL.-
The food we eat is transformed into,
among other things, energy (calories)
for our body. If we take in more
calories than we burn then the result is
an increase in weight and vice versa,
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
rate,
where
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%.
