Question

If you are 13 years old, which math problem would give you your maximum heart rate? Response area

If you are 13 years old, what is your maximum heart rate?Response area

After finding your maximum heart rate, remember your target heart rate zone is 70-85% of you maximum heart rate.

What would be the lower range or your target heart zone? Response area

What would be the upper limit? Response area

Answer 1

To calculate maximum heart rate, you can use the formula:

**Maximum Heart Rate = 220 - Age**

For a 13-year-old:

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

### Target Heart Rate Zone
To find the target heart rate zone, which is typically 70-85% of your maximum heart rate:

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

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

### Summary:
- **Maximum Heart Rate for a 13-year-old:** 207 bpm
- **Lower range of Target Heart Rate Zone:** 145 bpm
- **Upper limit of Target Heart Rate Zone:** 176 bpm
