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 used in the UK is: MHR = 220 - Age.

2. How Does the Calculator Work?

The calculator uses the standard MHR formula:

Where:

• \( Age \) — Age in years

Explanation: This formula provides a simple estimate of your maximum heart rate based on your age, which is widely used for exercise intensity planning.

3. Importance of MHR Calculation

Details: Knowing your maximum heart rate helps in designing effective exercise programs, determining appropriate training zones, and ensuring safe workout intensities.

4. Using the Calculator

Tips: 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: While widely used, it's an estimation. Individual maximum heart rates can vary by ±10-15 beats per minute from the calculated value.

Q2: Are there alternative formulas for MHR?
A: Yes, other formulas exist such as 208 - (0.7 × age) or 211 - (0.64 × age), but 220 - age remains the most commonly used standard.

Q3: How should I use my MHR for exercise?
A: MHR is used to calculate training zones (e.g., 50-60% for fat burning, 70-80% for cardiovascular training, 80-90% for anaerobic training).

Q4: Does fitness level affect maximum heart rate?
A: Fitness level doesn't significantly change maximum heart rate, though well-trained athletes may have slightly lower maximum rates.

Q5: When should I consult a doctor about heart rate?
A: If you experience chest pain, dizziness, or irregular heartbeat during exercise, or if you have pre-existing heart conditions.
