1. What is Max Heart Rate?

Max Heart Rate (Max HR) is the highest number of beats per minute your heart can reach during maximum physical exertion. It's an important parameter for exercise prescription and cardiovascular assessment.

2. How Does the Calculator Work?

The calculator uses the standard Max HR equation:

Where:

• \( \text{Age} \) — Age in years

Explanation: This formula estimates your maximum safe heart rate based on age, decreasing by approximately 1 beat per minute each year.

3. Importance of Max HR Calculation

Details: Knowing your max HR helps determine appropriate exercise intensity zones for training and ensures safe cardiovascular workouts.

4. Using the Calculator

Tips: Simply enter your age in years. The value must be valid (between 1-120 years).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It's a general estimate with standard deviation of ±10-12 bpm. Individual max HR can vary significantly.

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

Q3: Can I exceed my calculated max HR?
A: It's not recommended as it may increase cardiovascular risk, especially in untrained individuals.

Q4: Does fitness level affect max HR?
A: Fitness doesn't significantly change max HR, though it may improve recovery time and exercise capacity at high intensities.

Q5: When should I measure my actual max HR?
A: Only under medical supervision during graded exercise testing, as reaching true max HR can be dangerous.
