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. The most common formula to estimate MHR is 220 minus your age.

2. How Does the Calculator Work?

The calculator uses the simple MHR equation:

Where:

• \( age \) — Age in years (between 1 and 120)

Explanation: This equation provides a rough estimate of your maximum heart rate based on age alone. While simple, it's widely used for exercise prescription.

3. Importance of MHR Calculation

Details: Knowing your estimated maximum heart rate helps in designing safe and effective exercise programs. It's used to calculate target heart rate zones for different training intensities.

4. Using the Calculator

Tips: Simply enter your age in years (must be between 1-120). The calculator will estimate your maximum heart rate in beats per minute.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the 220-age formula?
A: It's a general estimate with standard deviation of about 10-12 bpm. Individual MHR can vary significantly due to genetics and fitness level.

Q2: Are there alternative MHR formulas?
A: Yes, some suggest 208 - (0.7 × age) or 211 - (0.64 × age) may be more accurate, especially for older adults.

Q3: Should I exercise at my maximum heart rate?
A: No, maximum heart rate is a theoretical limit. Training zones are typically 50-85% of MHR depending on fitness goals.

Q4: Does fitness level affect maximum heart rate?
A: Surprisingly, no. MHR is largely age-dependent. Fitness affects resting heart rate and recovery rate, not maximum.

Q5: Can medications affect maximum heart rate?
A: Yes, beta-blockers and other heart medications may lower your achievable maximum heart rate.
