Question

for a 65 year old with a resting heart rate of 64, the calculated Threshold and Upper Limit heart rate, using 65% and 80% would b

Answer 1

Patient age = 65

resting heart rate = 64

maximal heart rate = 220-age = 155.
So the upper limit of heart rate is 155.
The range is maximal heart rate - resting heart rate = 155-64 = 91
If the person is working at 65% of the range i.e. 59, threshold rate is 59 + 64(resting heart rate) =123.
If the person is working at 80% of the range i.e. 73, threshold rate is 73 + 64(resting heart rate) = 137.
ANSWER : upper limit heart rate = 155.
Threshold at 65% = 123.
Threshold at 80% = 155
