Heart Rate Zone Formula:
| From: | To: |
Heart rate zone calculation based on lactate threshold helps athletes determine optimal training intensities for different workout types, using their lactate threshold heart rate as a reference point.
The calculator uses the heart rate zone formula:
Where:
Explanation: The formula calculates target heart rate zones by multiplying your lactate threshold heart rate by the desired intensity percentage.
Details: Proper heart rate zone training helps optimize workout effectiveness, improve endurance, prevent overtraining, and track fitness progress over time.
Tips: Enter your lactate threshold heart rate in bpm and the desired intensity percentage (0-1). All values must be valid (LTHR > 0, intensity between 0-1).
Q1: What is lactate threshold heart rate?
A: Lactate threshold heart rate is the heart rate at which lactate begins to accumulate in the bloodstream faster than it can be removed, indicating intense exercise intensity.
Q2: How do I determine my lactate threshold heart rate?
A: It can be determined through laboratory testing or field tests such as a 30-minute time trial with average heart rate from the last 20 minutes.
Q3: What are typical heart rate training zones?
A: Common zones include Recovery (60-70% LTHR), Endurance (70-80% LTHR), Tempo (80-90% LTHR), and Threshold (90-100% LTHR).
Q4: Why use lactate threshold instead of maximum heart rate?
A: Training zones based on lactate threshold are more personalized and accurate for endurance athletes than zones based on maximum heart rate.
Q5: How often should I retest my lactate threshold?
A: It's recommended to retest every 4-6 weeks as your fitness level changes, or whenever you notice significant changes in your training performance.
