Heart Rate Zone Formula:
| From: | To: |
Heart Rate Zone calculation helps runners determine their optimal training intensity based on their Lactate Threshold Heart Rate (LTHR). Different percentages of LTHR correspond to different training zones for various workout types.
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 specific percentage values that correspond to different training intensities.
Details: Training in the appropriate heart rate zones helps runners optimize their workouts, improve performance, prevent overtraining, and achieve specific training goals more effectively.
Tips: Enter your Lactate Threshold Heart Rate in bpm and the desired percentage (0-1). Common training zones use percentages like 0.85-0.89 for tempo runs, 0.90-0.94 for threshold runs, etc.
Q1: How do I determine my Lactate Threshold Heart Rate?
A: LTHR can be determined through field tests (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 heart rate zones for runners?
A: Common zones include: Recovery (65-75% LTHR), Aerobic (75-85% LTHR), Tempo (85-89% LTHR), Threshold (89-94% LTHR), and VO2 Max (94-100%+ LTHR).
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 maximum heart rate.
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: Can weather conditions affect my heart rate zones?
A: Yes, heat, humidity, and altitude can affect heart rate. Adjust your effort accordingly and consider retesting in similar conditions for consistency.
