1. What is Max Heart Rate?

Max Heart Rate (MHR) is the highest number of beats per minute (bpm) your heart can achieve during maximum physical exertion. It's an important metric for designing safe and effective exercise programs.

2. How Does the Calculator Work?

The calculator uses the Tanaka formula:

Where:

• \( age \) — Age in years

Explanation: This formula is based on research showing a more gradual decline in maximum heart rate with age compared to the traditional 220-age formula.

3. Importance of MHR Calculation

Details: Knowing your MHR helps determine appropriate exercise intensity zones for cardiovascular training, fat burning, and performance improvement.

4. Using the Calculator

Tips: Simply enter your age in years. The value must be between 1 and 120. The calculator will estimate your maximum heart rate.

5. Frequently Asked Questions (FAQ)

Q1: Why use this formula instead of 220-age?
A: Research by Tanaka (2001) showed this formula is more accurate across a wider age range, especially for older adults.

Q2: What are typical MHR values?
A: For young adults, MHR is typically 190-200 bpm, decreasing to 160-170 bpm by age 60-70.

Q3: How should I use my MHR for exercise?
A: Exercise intensity is often expressed as a percentage of MHR (e.g., 50-70% for moderate, 70-85% for vigorous).

Q4: Are there limitations to this formula?
A: Individual variations exist due to genetics, fitness level, and medications. The only way to know your true MHR is through maximal exercise testing.

Q5: Is it safe to exercise at my MHR?
A: Only highly trained athletes should approach their MHR, and only briefly. Most training should occur at lower percentages.
