Question

1) TARGET HEART RATE

A 17 year old has a resting heart rate of 62 bpm. What is his/her maximum heart rate, heart rate reserve,
and target heart rate (you need to provide two numbers and round to the nearest whole number)? Be sure
to include bpm (beats per minute) after your numeric answer. You must show all of your work on how you
reached each final answer. If you do not round your target heart rate to the nearest whole number or add
the label to your answer it will be marked wrong.
1) Maximum heart rate =
2) Heart rate reserve =
3) Target heart rate =

Answer 1

A 17 year old with a resting heart rate of 62 bpm has a maximum hearth rate of 203 bpm, a hearth rate reserve of 141 bpm and target hearth rate between 161 and 182 bpm

Step-by-step explanation:

Target heart rate is a measure used to calculate the range of heart rate that should be maintained during intense exercise.

Knowing a person's age and resting heart rate (RHR), a target heart rate calculation can be made from the maximum heart rate (MHR) and the hearth rate reserve (HRR)

Data:

- Age: 17 years old

- RHR: 68 bpm

The maximum heart rate is calculated by subtracting age from a constant value of 220, so:

• MHR = 220 - age
• MHR = 220 - 17
• MHR = 203 bpm

HRR is calculated by subtracting the resting heart rate (RHR) from the MHR value:

• HRR = MHR - RHR
• HRR = 203 - 62
• HRR = 141 bpm

THR is obtained by multiplying the HRR by 0.7 and 0.85, to obtain the range of heart rate in which the exercise can be performed.

1. THR lower limit = (HRR x 0.7) + RHR Lower THR = (141 x 0.7) + 62 = 160.7 ≈ 161 bpm
2. THR top limit = (HRR x 0.85) + RHR THR top = (141 x 0.85) + 62 = 181,85 ≈ 182 bpm

For the 17-year-old, the ideal target heart rate for an intense exercise is between the values of 161 and 182 bpm.
