HPE 7B-U3 L11 Unit 3 Test Question 2

If you are 13 years old, which math problem would give you your maximum heart rate?-
If you are 13 years old, what is your maximum heart rate?-
After finding your maximum heart rate, remember your target rate zone is 70-85% of your maximum heart rate.
What would be the lower range of your target heart zone?-
What would be the upper limit?-

1 answer

To find your maximum heart rate, you can use the formula:

Maximum Heart Rate (MHR) = 220 - your age.

For someone who is 13 years old:

Maximum Heart Rate = 220 - 13 = 207 beats per minute (bpm).

Now, to find the target heart rate zone (which is 70-85% of your maximum heart rate), you can calculate the lower and upper limits:

  1. Lower range (70% of MHR): \[ 0.70 \times 207 = 144.9 \text{ bpm} \approx 145 \text{ bpm} \]

  2. Upper range (85% of MHR): \[ 0.85 \times 207 = 175.95 \text{ bpm} \approx 176 \text{ bpm} \]

Therefore:

  • Maximum Heart Rate: 207 bpm
  • Lower Limit of Target Heart Rate Zone: 145 bpm
  • Upper Limit of Target Heart Rate Zone: 176 bpm
