1. What is the NHS Maximum Heart Rate Formula?

The NHS Maximum Heart Rate Formula is a simple and widely used method to estimate an individual's maximum heart rate based on age. The formula is: MHR = 220 - Age.

2. How Does the Calculator Work?

The calculator uses the NHS formula:

Where:

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

Explanation: This formula provides a quick estimate of the maximum number of times your heart should beat per minute during physical activity.

3. Importance of MHR Calculation

Details: Knowing your maximum heart rate helps in designing appropriate exercise intensity levels, monitoring cardiovascular health, and ensuring safe physical activity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: What are typical MHR values?
A: Maximum heart rate typically decreases with age, ranging from about 200 bpm for young adults to 150 bpm for older individuals.

Q3: How should I use my MHR for exercise?
A: MHR is used to calculate target heart rate zones for different exercise intensities (e.g., 50-70% for moderate intensity, 70-85% for vigorous intensity).

Q4: Are there alternative formulas?
A: Yes, other formulas exist such as 208 - (0.7 × age) or 211 - (0.64 × age), which may be more accurate for certain populations.

Q5: Who should be cautious with this calculation?
A: Individuals with heart conditions, taking certain medications, or with specific health concerns should consult a healthcare professional before using heart rate calculations for exercise planning.
