1. What is Maximum Heart Rate (MHR)?

Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximum physical exertion. The standard formula MHR = 220 - Age provides a basic estimation of maximum heart rate based on age.

2. How Does the Calculator Work?

The calculator uses the MHR equation:

Where:

• \( MHR \) — Maximum Heart Rate (beats per minute)
• \( Age \) — Age in years

Explanation: This simple formula provides a general estimate of maximum heart rate that decreases with age.

3. Importance of MHR Calculation

Details: Knowing your maximum heart rate helps in designing effective exercise programs, determining appropriate training intensity zones, and monitoring cardiovascular health during physical activity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220 - Age formula?
A: This formula provides a general estimate but may not be accurate for all individuals. There can be significant variation (±10-12 bpm) from the predicted value.

Q2: Are there alternative MHR formulas?
A: Yes, other formulas exist such as 208 - (0.7 × age) or 211 - (0.64 × age), which may provide slightly different estimates.

Q3: How is MHR used in exercise training?
A: MHR is used to calculate target heart rate zones for different training intensities (e.g., 50-70% for fat burning, 70-85% for cardiovascular training).

Q4: Can medications affect maximum heart rate?
A: Yes, certain medications like beta-blockers can lower maximum heart rate, making this formula less accurate for individuals on such medications.

Q5: Should I get my MHR professionally tested?
A: For athletes or individuals with specific training goals, a stress test under medical supervision provides the most accurate measurement of maximum heart rate.
