1. What is Heart Rate Training Zone?

Heart rate training zones are specific intensity ranges used to guide exercise training. They help athletes train at the right intensity for their goals, whether it's endurance, fat burning, or performance improvement.

2. How Does the Calculator Work?

The calculator uses the heart rate zone formula:

Where:

• \( HRR \) — Heart rate reserve (Maximum HR - Resting HR)
• \( Intensity \) — Percentage of effort (0-1 scale)
• \( RHR \) — Resting heart rate (measured in bpm)

Explanation: The formula calculates the target heart rate for a specific training intensity based on your individual heart rate characteristics.

3. Importance of Training Zones

Details: Training in specific heart rate zones helps optimize workouts for different fitness goals, prevents overtraining, and allows for proper recovery.

4. Using the Calculator

Tips: Enter your heart rate reserve (max HR minus 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 measure my maximum heart rate?
A: The most accurate way is through a supervised stress test. Age-based formulas (220-age) are estimates only.

Q2: What are typical training zones?
A: Common zones are: Zone 1 (50-60% HRR) for recovery, Zone 2 (60-70%) for endurance, Zone 3 (70-80%) for aerobic, Zone 4 (80-90%) for threshold, Zone 5 (90-100%) for maximum effort.

Q3: When should I measure resting heart rate?
A: Measure first thing in the morning before getting out of bed, after several days of normal sleep.

Q4: Are there limitations to this calculation?
A: Individual variation exists. Those on certain medications or with heart conditions should consult a doctor before using HR zones.

Q5: How often should I recalculate my zones?
A: Reassess every 4-6 weeks as your fitness improves, as your resting HR may decrease and max HR may change.
