Heart Rate Training Zone Formula:
| From: | To: |
Heart Rate Training Zones are specific intensity ranges used to guide running training. They are calculated based on your Lactate Threshold Heart Rate (LTHR) and help optimize different aspects of your running performance.
The calculator uses the formula:
Where:
Explanation: The formula calculates your target heart rate zone by multiplying your lactate threshold heart rate by your desired training intensity percentage.
Details: Training in specific heart rate zones helps runners optimize their workouts, improve endurance, build speed, and prevent overtraining. Different zones target different physiological adaptations.
Tips: Enter your Lactate Threshold Heart Rate in bpm and the desired intensity as a decimal between 0 and 1. For example, 70% intensity would be entered as 0.70.
Q1: How do I determine my Lactate Threshold Heart Rate?
A: The most accurate method is through laboratory testing, but you can estimate it with a 30-minute time trial or field test with a heart rate monitor.
Q2: What are common training zones for running?
A: Typical zones include: Zone 1 (50-60% LTHR) for recovery, Zone 2 (60-70%) for aerobic base, Zone 3 (70-80%) for tempo, Zone 4 (80-90%) for threshold, and Zone 5 (90-100%) for VO2 max.
Q3: Should I use LTHR or maximum heart rate for training zones?
A: LTHR-based zones are generally more accurate for endurance training as they're based on your current fitness level rather than an age-predicted maximum.
Q4: How often should I retest my LTHR?
A: Every 4-6 weeks during training, as your fitness improves and your LTHR may change.
Q5: Can I use this calculator for other sports?
A: While the formula is the same, LTHR values are sport-specific. You should determine separate LTHR values for running, cycling, and other activities.
