Zone Heart Rate Formula:
| From: | To: |
Zone heart rate calculation helps runners determine their optimal training intensity based on their lactate threshold heart rate (LTHR). Different intensity percentages correspond to different training zones for various workout purposes.
The calculator uses the zone heart rate formula:
Where:
Explanation: The formula calculates the target heart rate for a specific training zone by multiplying your lactate threshold heart rate by the desired intensity percentage.
Details: Training in specific heart rate zones helps optimize workouts for different goals such as endurance building, speed development, or recovery. Understanding your zones allows for more effective and targeted training.
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: How do I determine my lactate threshold heart rate?
A: LTHR can be determined through field tests (like a 30-minute time trial) or laboratory testing. It's the average heart rate during the last 20 minutes of a maximal 30-minute effort.
Q2: What are typical intensity percentages for different zones?
A: Common training zones include: Recovery (0.65-0.75), Aerobic (0.75-0.85), Threshold (0.85-0.95), and VO2 Max (0.95-1.05).
Q3: Should I use maximum heart rate or LTHR for zone calculation?
A: LTHR-based zones are generally more accurate for runners as they're based on your actual metabolic threshold rather than an age-predicted maximum.
Q4: How often should I retest my LTHR?
A: Retest every 4-6 weeks as your fitness improves, or whenever you notice significant changes in your training performance.
Q5: Are there limitations to heart rate zone training?
A: Heart rate can be affected by factors like fatigue, hydration, temperature, and caffeine. Use perceived exertion alongside heart rate for best results.
