1. What is Target Heart Rate Zone?

The Target Heart Rate (THR) zone is the range of heartbeats per minute that aims to maximize cardiovascular benefits during exercise. For a 14-year-old, this is typically calculated as 60-80% of their maximum heart rate.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• 220 — Estimated maximum heart rate for humans
• age — Person's age in years
• 0.6 to 0.8 — Moderate exercise intensity range (60-80% of max HR)

Explanation: The equation estimates maximum heart rate based on age, then calculates the optimal range for cardiovascular exercise.

3. Importance of THR Calculation

Details: Exercising within your target heart rate zone ensures you're working hard enough to improve cardiovascular fitness without overexertion.

4. Using the Calculator

Tips: Enter your age in years. The calculator will show your optimal heart rate range for moderate exercise.

5. Frequently Asked Questions (FAQ)

Q1: Why is 220 used in the formula?
A: 220 is the commonly accepted estimate for maximum human heart rate, though individual variations exist.

Q2: Is this formula accurate for all ages?
A: It works reasonably well for most people, but athletes or those on certain medications may need adjusted calculations.

Q3: What's a normal THR for a 14-year-old?
A: Typically 123-164 bpm (based on 220-14 = 206 max HR × 0.6-0.8).

Q4: When should I measure my heart rate?
A: During exercise, take your pulse for 15 seconds and multiply by 4 to get bpm.

Q5: Are there limitations to this formula?
A: It doesn't account for fitness level, medications, or individual variations in max HR.
