Karvonen Formula:
| From: | To: |
The Karvonen Formula is a method used to calculate target heart rate during exercise. It takes into account both resting heart rate and maximum heart rate to provide a more personalized heart rate training zone.
The calculator uses the Karvonen Formula:
Where:
Explanation: The formula calculates personalized target heart rate by accounting for individual resting heart rate and adjusting for desired exercise intensity level.
Details: Calculating target heart rate is essential for effective exercise programming, ensuring you train at the appropriate intensity for your fitness goals, whether for fat burning, cardiovascular improvement, or athletic performance.
Tips: Enter resting heart rate and maximum heart rate in bpm, and intensity as a decimal between 0 and 1. All values must be valid (RHR > 0, MHR > RHR, intensity between 0-1).
Q1: How do I measure my resting heart rate?
A: Measure your pulse first thing in the morning before getting out of bed. Count beats for 60 seconds for most accurate results.
Q2: How do I determine my maximum heart rate?
A: The most accurate method is through maximal exercise testing. Alternatively, you can use the formula: 220 - age (though this is an estimate).
Q3: What intensity levels are recommended for different goals?
A: 50-60% for light exercise/warm-up, 60-70% for fat burning, 70-80% for aerobic fitness, 80-90% for anaerobic training, 90-100% for maximum effort.
Q4: Why use Karvonen instead of simple percentage of max HR?
A: Karvonen formula accounts for individual fitness level through resting heart rate, providing more personalized and accurate training zones.
Q5: How often should I recalculate my target heart rate?
A: Recalculate every 4-6 weeks as your fitness improves and your resting heart rate potentially decreases.
