1. What is %HRmax?

%HRmax (Percentage of Maximum Heart Rate) is a measure of exercise intensity relative to an individual's maximum heart rate. It's commonly used to determine appropriate exercise intensity zones for training.

2. How Does the Calculator Work?

The calculator uses the %HRmax equation:

Where:

• Current HR — Your current heart rate in beats per minute (bpm)
• Max HR — Your maximum heart rate in beats per minute (bpm)

Explanation: The equation calculates what percentage your current heart rate is of your maximum heart rate.

3. Importance of %HRmax Calculation

Details: %HRmax helps determine exercise intensity levels, which is crucial for designing effective training programs and ensuring safe exercise intensity for different fitness levels.

4. Using the Calculator

Tips: Enter your current heart rate and maximum heart rate in bpm. Both values must be positive numbers, and current HR should not exceed max HR.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my maximum heart rate?
A: The most common estimation is 220 minus your age, though individual variations exist. For more accuracy, consider a maximal exercise test.

Q2: What are the typical %HRmax zones?
A: Generally: 50-60% (very light), 60-70% (light), 70-80% (moderate), 80-90% (hard), 90-100% (maximum).

Q3: When should I measure my current HR?
A: During exercise for accurate intensity measurement, preferably after a few minutes of steady-state activity.

Q4: Are there limitations to %HRmax?
A: Yes, it doesn't account for resting HR or HR reserve. HR reserve (Karvonen method) may be more accurate for some individuals.

Q5: Is %HRmax suitable for everyone?
A: While generally useful, individuals on certain medications or with specific heart conditions should consult a doctor before using HR-based training.
