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?-

Answer 1

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
