Heart
Rate Monitoring
Several different methods [I have taken 4 from magazines
and checked on websites], none of which seem to fit me!! Finding the maximum
heart rate seems to be the hardest. I have found by trial and error that I
needed to add approximately 10 to 20 Beats to whatever the maximum worked out to be!
1.
The way you are supposed to do it is to
visit a sports lab [yeh! Right we all have access to one of those!] or
After warming up running for as fast as you can for 3 minutes check your heart rate.
After a few minutes of gentle running repeat your fast three minutes to find
your maximum heart rate [MHR] for example it might be 190.
Then find your resting heart rate, [ideally after you wake up] over a few days,
which may be 65.
Subtract your resting rate[RHR] from
your maximum [MHR] to find your working heart rate [WHR]. MHR-RHR = WHR e.g. 190-65 = 125.
Take whatever percentage of your working
heart rate you are aiming for e.g. 60%
that would be 125[WHR] x 0.6[60%] = 75
add this to your resting heart rate. 75
+ 65[RHR] =140 so a 60% effort would be 140 beats per minute[BPM].
The three
broad training zones are based on percentages of your working
heart rate [WHR] [ NOT Max Heart
Rate (MHR)] Broad Training Zones are 60% to 75% = easy, 75% to 85% moderate, 85%
to 95% hard.

There is an old formula of 220 – age = maximum heart rate [MHR] in
my case this would give me a maximum of 220-65=
155 which is about 20+ beats less than I think it is!!!
3.
Step 1 Calculate
maximum heart rate [MHR]
Women 209
- [0.9 x age] = MHR
Men 214
– [0.8 x age] = MHR
So for me age 65, that’s 214 – 0.8 x 65 = 162MHR
That’s still low but! Closer if I add 10
beats that’s 172 which I think is a lot nearer [I think mine is 176ish]
Step 2
Next take your resting heart rate [RHR]
Lie in bed before getting up or drinking
coffee etc. relax for 10 mins then count your pulse for one minute. Do this
over several days to find the average. Mine was 57.
Step 3 Using the following calculation to work out
your training zones
MHR [Max]
– RHR [Rest] = WHR[Working]
e.g. for me 162 -57 = 105 Working Heart
Rate
Calculate 70% and 85% of your working
heart rate
e.g. 70%
for me 70% of 105 = 73.5 bpm [beats per
minute]
80% of 105 = 84 bpm
THEN
[for 70%] add back your resting heart rate [RHR]
73.5 [70%of WHR] + 57[RHR] = 130.5
So 70%
= 130.5 bpm
80% is
84[80% of WHR] + 57[RHR] = 141 bpm

There is one final method of finding
maximum heart rate {MHR] and is called the ‘Maffatone method’
Coach Phil Maffatone used an easy method
of calculating your zones instead of worrying about maximum heart rate he uses
a simple formula!
180
- age = 70% if
you have been training for a year without injury add 5 beats
If you have been ill or out of training
take off 5 beats
So for me that would be 180 – 65 = 115 [i.e. My 70% is 142] which I
think is very low.

My rates through trial and error and
using the method 1 and 3 as a starting
point and seem to be close are
60%
=130
70% = 142
80% = 153
85% = 159
90% = 164
Most of my time in spinning is spent
around 75%/80% with the warm up being around 70% on the really hard bits I get
to around 87%maximum [160 bpm approximately]
6.
For a 52 year old woman
209
– 0.9 x 52 = MHR
209
– 0.9 x 52 = 162.2 Maximum Heart rate
If
resting heart rate was 63
then the working heart rate [WHR]
MHR
– RHR = WHR
163
– 63 = 100 working heart rate
60%
can be calculated as
60% x working heart rate + resting
heart rate = 60%
60%
0.6 x 100 + 63 = 123 bpm
70%
0.7x100
+ 63 = 133bpm
80%
0.8
x 100 + 63 =143bpm
90%
0.9
x 100 + 63 = 153bpm
This
seems low so you maybe need to add 10 bpm to the figures and see how it goes. I just
use as a guide to tell me when I am working and when I am not, it gives me a
target and I only go for the higher numbers when we are near the end of a
session!!
Good
luck!!!!

Excellent analysis, Yobo.
