Question

prompt 4: calculate your target heart rate zone (thrz):

maximum heart rate (mhr) \times .60 = low end of thrz
and
maximum heart rate (mhr) \times .90 = high end of thrz

write your answers here:

low end of thrz = ________ bpm
high end of thrz = ________ bpm
thrz = ______ (low end) to ______ (high end) bpm

Explanation:

Calculate the low end of the Target Heart Rate Zone

$$ \text{Low end of THRZ} = \text{MHR} \times 0.60 $$

Calculate the high end of the Target Heart Rate Zone

$$ \text{High end of THRZ} = \text{MHR} \times 0.90 $$

Express the Target Heart Rate Zone range

$$ \text{THRZ} = (\text{MHR} \times 0.60) \text{ to } (\text{MHR} \times 0.90) \text{ bpm} $$

Answer:

Prompt 4: Calculate your Target Heart Rate Zone (THRZ):

Maximum Heart Rate (MHR) x .60 = Low end of THRZ
AND
Maximum Heart Rate (MHR) x .90 = High end of THRZ

Write your answers here:

Low end of THRZ = <blank>\(\text{MHR} \times 0.60\)</blank> bpm

High end of THRZ = <blank>\(\text{MHR} \times 0.90\)</blank> bpm

THRZ = <blank>\(\text{MHR} \times 0.60\)</blank> to <blank>\(\text{MHR} \times 0.90\)</blank> bpm
