Answer:
Kevin, with a resting heart rate of 70 bpm has a maximum heart rate of 209 bpm, has a target rate hearth zone between 167 and 188 beats per minute.
Explanation:
Target heart rate is a measure used to calculate the heart rate range to be maintained during intense exercise.
By knowing the resting heart rate (RHR) and maximum heart rate (MHR), a target heart rate (THR) calculation can be made from the heart rate reserve (HRR)
Data:
- RHR = 70 bpm
- MHR = 209 bpm
Calculation of the heart rate reserve:
- HRR = MHR - RHR
- HRR = 209 - 70
- HRR = 139 bpm
Calculation of the target hearth rate:
THR is obtained by multiplying the HRR by 0.7 and 0.85, to obtain the heart rate range in which the exercise can be performed.
- Lower THR limit = (HRR x 0.7) + RHR
- Lower THR limit = (139 x 0.7) + 70 = 167.3 ≈ 167 bpm
- Upper limit of THR = (HRR x 0.85) + RHR
- Upper limit of THR = (139 x 0.85) + 70 = 188.15 ≈ 188 bpm
For Kevin, the ideal heart rate for intense exercise is between 167 and 188 beats per minute.
Note: Although the calculations were reviewed and are accurate, the result does not match the options given in the question.
