1. What is Maximum Heart Rate?

Maximum Heart Rate (MHR) is the highest number of beats per minute your heart can reach during maximum physical exertion. The NHS-recommended formula provides a simple estimate based on age.

2. How Does the Calculator Work?

The calculator uses the NHS-recommended formula:

Where:

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

Explanation: This formula provides a general estimate of your maximum safe heart rate, which decreases with age.

3. Importance of MHR Calculation

Details: Knowing your maximum heart rate helps determine appropriate exercise intensity levels, create safe workout plans, and monitor cardiovascular health during physical activity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It provides a general estimate but individual maximum heart rates can vary by ±10-15 beats per minute.

Q2: What are target heart rate zones for exercise?
A: Moderate intensity: 50-70% of MHR; Vigorous intensity: 70-85% of MHR.

Q3: Should everyone use the same formula?
A: While widely used, some populations may benefit from adjusted formulas. Consult a healthcare provider for personalized advice.

Q4: Can medications affect maximum heart rate?
A: Yes, certain medications like beta-blockers can lower maximum heart rate. Always consult your doctor about exercise limitations.

Q5: How often should I check my maximum heart rate?
A: Recalculate annually as your maximum heart rate decreases slightly with age.
