The identification of the exact anaerobic threshold has always been one of the objectives of the preparations to set the best training; methods are different (Conconi test, Wassermann test, Test of Mader and many others) but not all have the same result. Analyzing the real meaning of the anaerobic threshold as that intensity agreement in which the lactic acid product is also disposed of and then there is a constant level of lactic acid, lactate Massimo Test in Steady State (MLSS) turns out to be one of the most accurate.
We know that our body constantly produces lactic acid:
intensity below the anaerobic threshold in the cell can use the available oxygen, the lactic acid produced material which becomes oxidized and combustion;
at higher intensities the anaerobic threshold ' oxygen is not enough to keep things in balance and lactic acid product is oxidized in the cell and accumulate in the blood coming out of it;
finally at the anaerobic threshold, after an initial phase in which there is a small due to lactic acid build up oxygen, the lactate produced is nearly constant (or more precisely there growth of more than 1 m / Mol within 25-30 minutes), that is what is produced by glycolysis is oxidized inside the cell to be eliminated immediately. The oxygen is sufficient to maintain this balance. The
Test Maximum Lactate Steady State (MLSS) builds on the latter theory, it must identify the concentration of lactic acid in the blood at the anaerobic threshold (ie the actual maximum lactate steady state - MLSS), and the intensity (or in W, or F rate, or Km / h) of the anaerobic threshold, the test can be run in several ways, including tests with a duration of 20-30 minutes, but often the protocol used provides at least three steps with different loads (in Watts for cycling on a cycle ergometer in drag, in km / h on a treadmill for runners) for a period of 10 '. In the 10 'will be to analyze the performance of lactic acid with a withdrawal during and at the end of the step and associating the values \u200b\u200bof lactate obtained in each step you can find the maximum lactate steady state (MLSS) and 'in which intensity is maintained. The
Test Maximum Lactate Steady State (MLSS) turns out to be one of the most accurate ways to detect the real anaerobic threshold pace, and then locate the personal training and take that training. Also is very interesting as a benchmark for assessing the shape achieved.
