1. What is Maximum Heart Rate?

Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can achieve during maximum physical exertion. It's a key parameter used in exercise prescription and cardiovascular assessment.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

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

Explanation: This formula provides a simple estimation of maximum heart rate based on age, with heart rate typically decreasing by approximately 1 beat per minute per year.

3. Importance of MHR Calculation

Details: Calculating maximum heart rate is essential for designing effective exercise programs, determining appropriate exercise intensity levels, and establishing target heart rate zones for cardiovascular training.

4. Using the Calculator

Tips: Enter your age in years. The value must be between 1 and 120 years for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220 - age formula?
A: While widely used, this formula provides a general estimation. Individual maximum heart rates can vary by ±10-15 beats per minute from the predicted value.

Q2: Are there alternative formulas for MHR?
A: Yes, other formulas include 208 - (0.7 × age) and 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 improvement).

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

Q5: Should athletes use this formula?
A: While useful for general population, highly trained athletes may have different heart rate responses, and field tests may provide more accurate MHR measurements.
