1. What is Maximum Predicted Heart Rate?

The maximum predicted heart rate is the highest heart rate an individual can achieve during maximal physical exertion. The most common formula used is: 220 - age.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Age — The person's age in years

Explanation: This equation provides a rough estimate of maximum heart rate which declines with age.

3. Importance of Maximum Heart Rate

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

4. Using the Calculator

Tips: Simply enter your age in years. The value must be between 1 and 120 years.

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 maximum heart rates can vary significantly.

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

Q3: What factors affect maximum heart rate?
A: Genetics is the primary factor. Medications, fitness level, and altitude can also influence it.

Q4: Should I exercise at my maximum heart rate?
A: No, maximum heart rate is a reference point. Training zones are typically percentages of max HR (e.g., 60-80% for aerobic exercise).

Q5: Can maximum heart rate be increased?
A: No, it's genetically determined and decreases with age. However, you can improve how efficiently your heart works at submaximal levels.
