Aerobic Threshold Heart Rate Calculator

Calculate aerobic threshold (AeT) heart rate — the intensity at which lactate begins to accumulate — from VO2 max or field test data for base training.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate aerobic threshold (AeT) heart rate — the intensity at which lactate begins to accumulate — from VO2 max or field test data for base training

Each component has a specific meaning:

  • VO2 max or field test data — The vo2 max or field test data recorded for the scenario being assessed.

Note: Interpret the aerobic threshold hr result against the thresholds and context described above.

How to Use

Enter the VO2 max or field test data for the scenario you are assessing. Calculate aerobic threshold (AeT) heart rate — the intensity at which lactate begins to accumulate — from VO2 max or field test data for base training. Use the aerobic threshold hr result to inform your calculation.
