1. What is Zone Heart Rate?

Zone Heart Rate refers to specific intensity ranges expressed as percentages of your Maximum Heart Rate (MHR). Different zones target different fitness goals such as fat burning, aerobic endurance, or anaerobic performance.

2. How Does the Calculator Work?

The calculator uses the zone heart rate formula:

\[ Zone = MHR \times \% Intensity \]

Where:

\( MHR \) — Maximum Heart Rate (beats per minute)
\( \% Intensity \) — Training intensity expressed as decimal (0-1)

Explanation: The formula calculates the target heart rate for a specific training zone by multiplying your maximum heart rate by the desired intensity percentage.

3. Importance of Heart Rate Zones

Details: Training in specific heart rate zones helps optimize workouts for different fitness goals, prevents overtraining, and ensures you're working at the right intensity for your objectives.

4. Using the Calculator

Tips: Enter your maximum heart rate in bpm and the desired intensity as a decimal between 0 and 1 (e.g., 0.65 for 65% intensity). All values must be valid (MHR > 0, intensity between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my Maximum Heart Rate?
A: The most common method is 220 minus your age, but this is an estimate. For accuracy, consider a graded exercise test under professional supervision.

Q2: What are the typical heart rate zones?
A: Common zones include: Zone 1 (50-60% - warmup/recovery), Zone 2 (60-70% - fat burning), Zone 3 (70-80% - aerobic), Zone 4 (80-90% - threshold), Zone 5 (90-100% - maximum effort).

Q3: Why train in different heart rate zones?
A: Different zones develop different physiological adaptations - endurance, fat metabolism, lactate threshold, and VO2 max improvements.

Q4: Should heart rate zones change over time?
A: Yes, as your fitness improves, you may need to adjust your zones to continue making progress and avoid plateaus.

Q5: Are there limitations to heart rate zone training?
A: Heart rate can be affected by factors like stress, caffeine, dehydration, and medications. Perceived exertion should also be considered alongside heart rate data.
