1. What is Target Heart Rate?

Target Heart Rate (THR) is the desired heart rate range you aim to achieve during exercise for optimal cardiovascular benefits. It's calculated based on your maximum and resting heart rates, and the intensity of exercise you want to achieve.

2. How Does the Calculator Work?

The calculator uses the Karvonen formula:

Where:

• \( MHR \) — Maximum Heart Rate (bpm)
• \( RHR \) — Resting Heart Rate (bpm)
• \( Intensity \) — Exercise intensity as percentage (50-85% typically)

Explanation: This formula accounts for individual differences in resting heart rate, providing a more personalized target than simple percentage-based methods.

3. Importance of Target Heart Rate

Details: Training within your target heart rate zone ensures you're exercising at the right intensity to improve cardiovascular fitness without overexertion. Different zones provide different benefits (fat burning, aerobic improvement, etc.).

4. Using the Calculator

Tips:

• Measure resting heart rate in the morning before getting out of bed
• Maximum heart rate can be estimated as 220 - age (though individual variation exists)
• Typical exercise intensities: 50-60% (light), 60-70% (fat burning), 70-80% (aerobic), 80-90% (anaerobic)

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the maximum heart rate formula (220 - age)?
A: It's a general estimate with ±10-12 bpm standard deviation. Individual maximum heart rates can vary significantly.

Q2: What's the best way to measure resting heart rate?
A: Measure your pulse for 60 seconds first thing in the morning, before getting out of bed, for several days and take the average.

Q3: Are there different target zones for different goals?
A: Yes, 50-60% for light exercise/recovery, 60-70% for fat burning, 70-80% for aerobic fitness, 80-90% for anaerobic training.

Q4: Should everyone use the same intensity percentages?
A: Beginners should start at lower intensities (50-65%) and gradually increase. Consult a doctor before starting intense exercise programs.

Q5: How does fitness level affect target heart rate?
A: As fitness improves, your resting heart rate typically decreases, which may slightly change your target zones at given intensities.
