Blood lactate test in the road race

This field test is based on the evolution of blood lactate concentrations according to the speed of travel. It is certainly more precise but also more complex as the blood collection is required, the presence of specialized personnel and the execution of an examination that requires equipment that are usually not common.

This test consists in making a certain number of repetitions, which are usually at least four, on a fixed distance and at a constant speed. In each subsequent trial, the speed of execution increases and at each test end a small amount of blood is taken from the earlobe or from the fingertip of a finger to measure lactate concentration.

The data obtained are shown on a graph that allows the construction and the visualization of a curve that describes the lactate trend as a function of the travel speed.

Normally the tests are carried out over a distance of 2000-3000 meters; the use of greater distances would lead to a decrease in the number of tests. It is also essential to change the speed between the various runs: for a correct run there must be an increase of about 0.15-0.30 km / h equal to 2.5-5 seconds per kilometer. For the right speed maintenance, an acoustic signal is used along the track, which dictates the exact rhythm to maintain.

The blood lactate test in addition to predicting the competition time, can be used to direct training and to assess the effects of a certain period of preparation. Knowing that the speed corresponding to a concentration of lactate equal to 4 mmol / liter is that of the anaerobic threshold, it can be noted that when the work is done correctly and the preparation was the right one, there is a decrease in the concentrations of lactate at the same speed.
