Find the low and high target heart rate zones for a 46-year-old teacher from El Cerrito Middle School with a resting heart rate
alexgriva [62]

The low and high target heart rate zones for the 46-year-old teacher with a resting heart rate of 78bpm are;

Low target heart rate = 87 bpm

High target heart rate = 131 bpm

We are told that the resting heart rate of the 46 year old teacher is 78 bpm.

Now, the formula for calculation of the estimated maximum age-related heart rate is;

Maximum age related heart rate = 220 – person's age

For this 46 year old man;

Maximum age related heart rate = 220 - 46

Maximum age related heart rate = 174 bpm

Now. since his resting heart rate is average at 78 bpm, then the low and high target heart rate will be gotten from the formula;

Low target heart rate = 50% × Maximum age related heart rate

High target heart rate = 75% × Maximum age related heart rate

Thus;

Low target heart rate = 50% × 174

Low target heart rate = 87 bpm

High target heart rate = 75% × 174

High target heart rate ≈ 131 bpm
