1. What is Heart Rate Reserve Zone?

The Heart Rate Reserve (HRR) method is a way to calculate target heart rate zones that takes into account both your maximum and resting heart rates, providing a more personalized approach to exercise intensity.

2. How Does the Calculator Work?

The calculator uses the HRR formula:

Where:

• \( HRR \) — Heart Rate Reserve (Max HR - Resting HR)
• \( Intensity \) — Desired training intensity (0-1 scale)
• \( Resting\ HR \) — Your resting heart rate

Explanation: The equation calculates your target heart rate for a specific training zone by applying the intensity percentage to your heart rate reserve and adding back your resting heart rate.

3. Importance of HRR Calculation

Details: HRR provides a more accurate method for determining exercise intensity than simple percentage of maximum heart rate, as it accounts for individual differences in resting heart rate.

4. Using the Calculator

Tips: Enter your heart rate reserve (max HR - resting HR), desired intensity (0-1 scale), and resting heart rate. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my heart rate reserve?
A: HRR is calculated by subtracting your resting heart rate from your maximum heart rate (220 - age is a common estimate for max HR).

Q2: What are typical intensity levels?
A: Moderate intensity is typically 40-59% (0.4-0.59), vigorous is 60-89% (0.6-0.89) of HRR.

Q3: When should I measure my resting heart rate?
A: Measure first thing in the morning before getting out of bed for most accurate resting HR.

Q4: Are there limitations to this method?
A: Accuracy depends on correct max HR and resting HR values. Those on certain medications may have altered HR responses.

Q5: How does this compare to % of max HR method?
A: HRR method typically results in slightly higher target zones than % max HR method, especially for fit individuals with low resting HR.
