Exercise 4

Briefly explain the technique employed to determine the lactate threshold and the ventilatory threshold.

Step 1 of 3

In distance running events like marathon, the maximal steady-state running is useful in predicting success. Lactate threshold is one of the tests used to predict success in endurance events. It represents an exercise intensity wherein the levels of blood lactate begin to increase at a constant rate. Lactate threshold would be related to endurance performance since accumulation of lactate in muscles and blood causes fatigue.
