Achieve your
target heart rate
By Anup Deb Nath
TO achieve the maximum benefit from
any exercise programme, it is essential that it be done
correctly, for the minimum time span required and
sustained over a period of time for it to be effective.
If our exercise programme is going to be more off than on
or the time spent exercising is not enough, or the
exercise is not done seriously for the minimum number of
days, it will not give the desired benefit. Exercise will
be effective if it is done about three to five times a
week and each session lasts for 30-40 minutes.
Many people who start
exercising are confused about how much is enough and at
times are even worried that they are overdoing it. Some
often asked queries on the time and pace of exercises.
I have been doing
aerobics for three months. Despite this, I have not lost
any weight. Everyone says I look better now but the
needle on the weighing scale just wont budge. I
want to lose at least 4 kg. Could you advise me on how to
achieve this?
Its good to know
that you have joined an exercise programme though do
remember that three months is not all that, long a time.
Dont worry and give it some more time. One anxious
moment is when, after a couple of months of high
intensity aerobics, you climb on to the weighing scale
only to find the needle showing you have gained. People
certainly dont expect any movement towards this end
of the scale. The reason why many people gain or then
stay steady on the weighing scale, despite dedicated
workouts, is easily explained. When you start any
exercise programme you lose fat and gain muscle.Fat
weighs less than muscle as muscle composition is more
dense. If there has been any muscle gain it will register
on the scale.
The correct way to gauge
how much you have lost would be to monitor your weight as
well as your size in inches. This way even if you are
gaining muscle and showing an increase in weight but your
inches are decreasing you are on the right track and need
not worry. Also remember that it is more important how
you look and feel rather than what your weight is.
I go for a 5-km jog
everyday. My friend tells me that I should work out at my
bodys target heart rate for the exercise to really
benefit me. Is this correct? Please could you also tell
me what is target heart rate and how do I calculate it?
Is there any other method of calculating my workout
intensity apart from this?
Yes, your
friend is correct. You should workout according to your
bodys target heart rate in order to achieve the
maximum benefit from your exercise. The heart rate is the
number of times your heart beats per minute. The resting
heart rate is the number of times your heart beats while
you are completely at rest. The average person has a
resting heart rate of 60-85 beats per minute. Many
athletes and sports people have a lower resting heart
rate, which means that with every beat of their heart a
larger volume of blood is pumped easily through their
bodies. To measure your resting heart rate the best way
is to take it the minute you wake up in bed. This should
ideally be taken before you so much as sit up.
Target heart rate is the
ideal range of heartbeat, per minute, to make your
workout effective. In order to calculate your target
heart rate you need to know your maximum heart rate.
To calculate your maximum
heart rate, subtract your age from 220, the answer you
get is your maximum heart rate. For instance if you are
30 years old, then 220-30=190 which is your maximum heart
rate. The target heart rate varies from 60 per cent to 80
per cent of your maximum heart rate; this variation will
depend on your fitness level. Taking the above example
for a maximum heart rate of 190, a person who is
physically very active and fit would calculate his target
heart rate at the higher end of 80 per cent while a
person of the same maximum heart rate but a lower fitness
level would calculate it at the lower end of 60 per cent.
According to the Karvonen
formula, you can calculate your target heart rate by
taking your pulse first thing in the morning for three
consecutive days, (we are taking the readings at 69, 70
and 71 which averages at 70).
Now calculate your target
heart rate by subtracting your age from 220, (220-30=190)
and then subtracting the average of your resting heart
rate (190-70=120). The lower range is calculated at 50
per cent of this plus your resting heart rate
(120x.5+70=130). The higher range is calculated at 85 per
cent plus your resting heart rate (120x.85+70=172).
In other words, according
to this theory, a person who is 30 years old should work
out between the range of 130-172 BPM. Another way to
gauge the intensity of your workout is using the Borg
scale of perceived exertion.
On a scale of 1-10 try to
calculate how much you are exerting during your workout
with 10 reflecting the maximum effort and 1 the least
amount. The intensity of your workout should make you
work at your target heart rate and you should also
sustain it at this for at least 25-35 minutes, at a time,
for it to benefit you.
