Question

Maximum Heart Rate: (220-age):____________
Target Heart Rate: (220 – age x .50 to .85)
age=14

Answer 1

To calculate the Maximum Heart Rate (MHR) and Target Heart Rate (THR) for a 14-year-old, we'll follow the formulas provided.

1. **Maximum Heart Rate (MHR)**:
\[
\text{MHR} = 220 - \text{age}
\]
\[
\text{MHR} = 220 - 14 = 206 \text{ beats per minute}
\]

2. **Target Heart Rate (THR)**:
\[
\text{THR} = (220 - \text{age}) \times 0.50 \text{ to } 0.85
\]
- Lower end (50%):
\[
\text{THR}_{\text{lower}} = 206 \times 0.50 = 103 \text{ beats per minute}
\]
- Upper end (85%):
\[
\text{THR}_{\text{upper}} = 206 \times 0.85 = 175.1 \text{ beats per minute} \approx 175 \text{ beats per minute}
\]

So, for a 14-year-old:
- Maximum Heart Rate: **206 bpm**
- Target Heart Rate Range: **103 bpm to 175 bpm**
