Karvonen Formula Calculator
Tool Introduction:
Karvonen Formula Calculator accurately calculates target heart rate and heart rate reserve based on age and exercise intensity. Ideal for aerobic exercise, fat burning training, and heart rate monitoring.
Karvonen Formula:
Heart Rate Zones
| Intensity | Heart Rate (bpm) |
|---|---|
| 50% (Light Exercise) | 130 bpm |
| 60% (Fat Burning Zone) | 142 bpm |
| 70% (Aerobic Exercise) | 154 bpm |
| 80% (Anaerobic Threshold) | 166 bpm |
| 90% (High Intensity) | 178 bpm |
| 100% (Maximum Intensity) | 190 bpm |
What is the Karvonen Formula?
The Karvonen Formula is a scientific method for calculating target heart rate based on heart rate reserve, developed by Finnish physiologist Martti Karvonen. This formula considers individual differences in resting heart rate, making it more accurate than simple maximum heart rate percentage methods.
Advantages of the Karvonen Formula: More precise personalized calculations, considers resting heart rate differences, suitable for people of different fitness levels, and scientifically determines exercise intensity.
Usage Guide
- Resting Heart Rate: Heart rate measured before getting up in the morning or in a quiet state. Normal range for adults is 60-100 bpm.
- Maximum Heart Rate: Can be estimated by age (220-age) or obtained through professional testing.
- Exercise Intensity: Choose based on training goals - fat burning 60-70%, aerobic 70-80%, anaerobic 80-90%.
