1. What is Max Predicted Heart Rate?

The Max Predicted Heart Rate is the highest heart rate an individual can achieve during maximal physical exertion. This calculator estimates it based on age and weight using a regression equation.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Age \) — Age in years
• \( Weight \) — Weight in kilograms

Explanation: The equation accounts for the decrease in maximum heart rate with increasing age and weight.

3. Importance of Max HR Calculation

Details: Knowing your maximum heart rate helps in designing appropriate exercise intensity levels for cardiovascular training and monitoring exercise safety.

4. Using the Calculator

Tips: Enter your age in years and weight in kilograms. All values must be valid (age between 1-120, weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this formula compared to others?
A: This formula incorporates both age and weight, making it more personalized than the traditional 220-age formula.

Q2: What are typical max HR values?
A: For most adults, max HR ranges between 150-200 bpm, decreasing with age.

Q3: When should I measure my max HR?
A: Max HR is best measured during a graded exercise test under medical supervision.

Q4: Are there limitations to this equation?
A: Individual variations exist due to fitness level, genetics, and medications. Always consult a physician before intense exercise.

Q5: How should I use my max HR?
A: It's used to calculate target heart rate zones for different training intensities (e.g., 50-85% of max HR).
