The formula to calculate the Lactate Threshold is:
\[ LT = HR_{max} \times \left(1 - \frac{LT\%}{100}\right) \]
Where:
The lactate threshold refers to the intensity of exercise at which lactate, a byproduct of anaerobic metabolism, begins to accumulate in the bloodstream at a faster rate than it can be removed. This threshold is significant because it is an indicator of fatigue during strenuous exercise. When the body is working within its lactate threshold, it is able to efficiently remove the lactate produced by the muscles and use it as a source of energy.
Let's assume the following values:
Using the formula:
\[ LT = 190 \times \left(1 - \frac{85}{100}\right) = 190 \times 0.15 = 28.5 \text{ bpm} \]
The Lactate Threshold is 28.5 bpm.
Let's assume the following values:
Using the formula:
\[ LT = 180 \times \left(1 - \frac{80}{100}\right) = 180 \times 0.20 = 36 \text{ bpm} \]
The Lactate Threshold is 36 bpm.
