1. What is Maximum Heart Rate?

Maximum Heart Rate (Max HR) is the highest heart rate an individual can achieve during maximal physical exertion. The most common formula to estimate it is 220 minus age.

2. How Does the Calculator Work?

The calculator uses the simple Max HR equation:

Where:

• Age — Person's age in years

Explanation: This formula provides a rough estimate of maximum heart rate which declines with age.

3. Importance of Max HR Calculation

Details: Knowing your maximum heart rate helps in setting 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.

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: How is max HR used in exercise?
A: Exercise intensity is often prescribed as percentage of max HR (e.g., 60-70% for moderate intensity).

Q4: Can medications affect max HR?
A: Yes, beta blockers and other medications can lower max HR. Consult your doctor for personalized advice.

Q5: Should athletes use this formula?
A: Highly trained athletes may need more precise measurement through maximal exercise testing.
