1. What is the Maximum Heart Rate Formula?

The Maximum Heart Rate (MHR) formula estimates the highest heart rate an individual can achieve during maximum physical exertion. The most common formula is: MHR = 220 - Age.

2. How Does the Calculator Work?

The calculator uses the Maximum Heart Rate equation:

Where:

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

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

3. Importance of MHR Calculation

Details: Knowing your maximum heart rate helps determine appropriate exercise intensity zones for cardiovascular training, ensuring safe and effective workouts.

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 a population average and individual variations exist. It may underestimate MHR in younger people and overestimate in older adults.

Q2: Are there alternative MHR formulas?
A: Yes, other formulas include: 208 - (0.7 × age) and 211 - (0.64 × age), which may be more accurate for certain populations.

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 fitness).

Q4: Should everyone use the same formula?
A: Individual factors like fitness level, genetics, and medications can affect MHR. For precise training, consider professional assessment.

Q5: Can MHR change over time?
A: Yes, maximum heart rate typically decreases with age by approximately 1 beat per minute per year.
