1. What is Maximum Heart Rate?

Maximum Heart Rate (MHR) is the highest number of times your heart can beat in one minute during maximal physical exertion. The most common formula to estimate MHR is 220 minus your age.

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Max HR} = 220 - \text{Age} \]

Where:

Explanation: Maximum heart rate declines with age due to natural physiological changes in the heart's conduction system.

3. Importance of Maximum Heart Rate

Details: Knowing your maximum heart rate helps determine appropriate exercise intensity levels and target heart rate zones for training.

4. Using the Calculator

Tips: Simply enter your age in years. The value must be between 1 and 120 years for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Is the 220-age formula accurate for everyone?
A: While widely used, it's an estimate. Individual variations can be ±10-20 beats per minute.

Q2: Are there alternative formulas?
A: Yes, some suggest 208 - (0.7 × age) or 211 - (0.64 × age) may be more accurate for certain populations.

Q3: How is maximum heart rate used in exercise?
A: It helps calculate target heart rate zones (e.g., 50-85% of max HR) for different training intensities.

Q4: Does fitness level affect maximum heart rate?
A: No, fitness doesn't change max HR, though it may improve recovery time and lower resting heart rate.

Q5: Should I exercise at my maximum heart rate?
A: Generally no - sustained exercise at max HR is dangerous for most people. Training typically occurs at 60-90% of max HR.
